15 Challenging NCLEX Practice Questions to Test Your Clinical Judgment

This NCLEX practice test is built for candidates who are ready to move beyond straightforward knowledge questions and challenge their clinical judgment at the difficulty level the actual exam delivers. Each of the 15 questions below is constructed at the application or analysis cognitive level — meaning the correct answer requires integrating clinical data, applying a reasoning framework, and selecting the option that is not just clinically accurate but specifically correct for the patient, the moment, and the nursing decision described in the scenario.

The questions in this NCLEX practice test span the highest-yield content categories on the 2026 exam: medical-surgical nursing, pharmacology, prioritization and delegation, maternal-newborn, mental health, and Next Generation NCLEX clinical judgment formats. Each question is followed by a full rationale that explains not only why the correct answer is right but specifically why each incorrect option fails — because understanding why distractors are wrong is as important as knowing why the correct answer is correct. Use this NCLEX practice test the way high-performing candidates use their question bank: read each stem twice, generate your own answer before reading the options, commit to your selection, and then read every rationale whether you answered correctly or not. If you answer a question incorrectly, identify which reasoning error produced the wrong selection — misread action verb, wrong process step, incorrect priority framework, or assumption not supported by the stem. That analysis is what converts a practice question into a clinical reasoning lesson.

How to Use This NCLEX Practice Test

Before reading the answer options for each question, read the stem twice: first to build clinical situational awareness, then to identify the specific action verb that tells you what type of nursing decision is being tested. Generate your best clinical answer from the stem alone before engaging the options. This pre-answer generation habit is the practice behavior most directly associated with improved clinical judgment performance on the actual exam.

• Time yourself: Allow 60 to 90 seconds per question to simulate exam pacing. If you exceed 90 seconds on a single question during this NCLEX practice test, note it — sustained time overruns on specific question types indicate a reasoning pattern to address.
• Read every rationale: Whether you answered correctly or not, read the full rationale including the explanations for each incorrect option. The distractors in this NCLEX practice test are constructed from real clinical misconceptions — understanding why they are wrong closes the reasoning gaps they exploit.
• Track your errors: After completing all 15 questions, categorize your incorrect answers by error type: wrong process step, wrong priority framework, misread action verb, or clinical knowledge gap. The pattern tells you precisely what to address next in your preparation.

Questions 1–5: Medical-Surgical Nursing and Prioritization

QUESTION 1  |  Medical-Surgical — Prioritization

A nurse on a medical-surgical floor is managing four patients. Which patient requires the most immediate assessment?

A.  A 58-year-old with COPD whose oxygen saturation is 91% on 2 L/min nasal cannula, which is their baseline.

B.  A 44-year-old who is 6 hours post-appendectomy and reports pain rated 6 out of 10 at the incision site.

C.  A 67-year-old with heart failure who has gained 1.8 kg since yesterday and reports increased shortness of breath when walking to the bathroom.

D.  A 72-year-old with a hip fracture repair who became acutely confused 30 minutes ago, has a heart rate of 118, and blood pressure of 88/54 mmHg.

✔  Correct Answer: D

Rationale

The patient in option D is exhibiting classic early signs of hypovolemic shock: acute-onset confusion indicating decreased cerebral perfusion, tachycardia, and hypotension. This constellation of findings represents an immediate threat to life and requires assessment and intervention before any other patient. Hemodynamic instability with altered mental status in a post-operative patient strongly suggests hemorrhage until proven otherwise.

A is incorrect: An oxygen saturation of 91% on 2 L/min is documented as this patient’s baseline. A value that is expected and unchanged from the patient’s established baseline does not constitute an acute change requiring immediate priority assessment.

B is incorrect: Post-operative incisional pain rated 6 out of 10 at 6 hours post-appendectomy is an expected finding. It requires assessment and pain management but does not represent an acute physiological emergency.

C is incorrect: A 1.8 kg weight gain and exertional dyspnea in a heart failure patient indicates fluid retention requiring assessment and likely intervention, but the patient is ambulating independently, which signals that the situation — while concerning — is not immediately life-threatening in the same way as option D’s hemodynamic instability.

QUESTION 2  |  Medical-Surgical — Neurological

A nurse is caring for a patient with a traumatic brain injury who has been stable for two days. The patient suddenly becomes increasingly drowsy and begins to exhibit unequal pupils, with the left pupil now 6 mm and non-reactive. What is the nurse’s priority action?

A.  Reposition the head of bed to 30 degrees and ensure the head is in midline alignment.

B.  Notify the provider immediately and prepare for urgent intervention.

C.  Complete a full Glasgow Coma Scale assessment and document the findings.

D.  Increase the frequency of neurological checks to every 15 minutes.

✔  Correct Answer: B

Rationale

A fixed, dilated pupil combined with a decreasing level of consciousness in a TBI patient is a neurological emergency indicating uncal herniation — the temporal lobe herniating through the tentorium cerebelli and compressing cranial nerve III. This is a life-threatening change that requires immediate provider notification and preparation for urgent neurosurgical intervention. Every minute of delay worsens outcomes irreversibly.

A is incorrect: Head-of-bed elevation to 30 degrees in midline is an appropriate ongoing intervention for ICP management, but it is a maintenance measure — not an emergency response to acute herniation. Repositioning while the patient is actively herniating without simultaneously notifying the provider is a dangerous delay.

C is incorrect: Completing a GCS assessment is a component of neurological monitoring and has already been implicitly done by identifying the change — further assessment documentation without immediate provider notification wastes critical time in a herniation emergency.

D is incorrect: Increasing monitoring frequency is appropriate for a patient showing early signs of neurological deterioration, but this patient has already progressed to fixed, dilated pupils — a sign of advanced, immediately life-threatening deterioration that requires emergency intervention, not closer monitoring.

QUESTION 3  |  Medical-Surgical — Cardiovascular

A nurse is caring for a patient on telemetry who was admitted with chest pain. The patient calls the nurse and reports sudden onset of palpitations, lightheadedness, and near-syncope. The monitor shows a regular rhythm at 178 bpm with narrow QRS complexes. Which action does the nurse take first?

A.  Administer the prescribed PRN dose of metoprolol 25 mg orally.

B.  Obtain a 12-lead ECG and notify the provider of the rhythm change.

C.  Instruct the patient to bear down as if having a bowel movement and apply a cold, wet cloth to the face.

D.  Prepare for immediate synchronized cardioversion per the provider order.

✔  Correct Answer: C

Rationale

The presentation describes supraventricular tachycardia — a regular narrow-complex tachycardia with symptoms. For a patient who is hemodynamically stable (symptomatic but not in shock, not unconscious, not severely hypotensive), the first-line nursing intervention is vagal maneuvers: Valsalva maneuver (bearing down) and carotid sinus stimulation via cold facial stimulus. These parasympathetic maneuvers may terminate SVT without pharmacological or electrical intervention. The nurse attempts vagal maneuvers first before escalating to medication or cardioversion.

A is incorrect: Oral metoprolol takes 1 to 2 hours to reach therapeutic effect and is not an appropriate acute intervention for SVT with hemodynamic symptoms. IV formulations may be used in acute management after vagal maneuvers fail, but the oral route is incorrect in this situation.

B is incorrect: A 12-lead ECG and provider notification are important and will occur as part of ongoing management, but they are not the first action — vagal maneuvers are a safe, immediate intervention that should be attempted before escalating to diagnostic and provider communication steps.

D is incorrect: Synchronized cardioversion is appropriate for hemodynamically unstable SVT — a patient who is hypotensive, unconscious, or in acute pulmonary edema. This patient is symptomatic but stable, which places them in the vagal maneuver and pharmacological intervention pathway, not the immediate cardioversion pathway.

QUESTION 4  |  Prioritization and Delegation

A charge nurse is assigning patients to staff at the beginning of a shift. Which patient is most appropriate to assign to a nursing assistant?

A.  A patient with newly diagnosed type 1 diabetes who requires insulin education before discharge this afternoon.

B.  A stable patient with chronic heart failure admitted for routine medication adjustment who needs vital signs taken and morning hygiene assistance.

C.  A patient receiving a blood transfusion who is 30 minutes into the first unit.

D.  A post-operative patient who is 4 hours after a laparoscopic cholecystectomy and reports nausea and pain rated 5 out of 10.

✔  Correct Answer: B

Rationale

A stable, chronic heart failure patient requiring vital signs and morning hygiene assistance is an appropriate nursing assistant assignment. Both tasks — vital sign measurement for a stable patient and basic hygiene care — are within the nursing assistant’s scope of practice and do not require professional nursing judgment. The patient’s condition is stable and not acutely changing.

A is incorrect: Insulin education requires professional nursing judgment, individualized teaching based on assessment of the patient’s learning needs and health literacy, and evaluation of learning outcomes. This is an RN responsibility and cannot be delegated to a nursing assistant.

C is incorrect: Blood transfusion monitoring requires nursing assessment skills — identifying early signs of transfusion reactions including fever, chills, urticaria, back pain, and dyspnea. The RN must assess the patient at regular intervals throughout the transfusion. This cannot be delegated to a nursing assistant.

D is incorrect: A post-operative patient 4 hours after surgery with active nausea and pain requires nursing assessment of post-operative recovery status, evaluation of vital signs in the context of post-operative complications, and clinical judgment about pain and nausea management. This patient requires RN monitoring, not nursing assistant care.

QUESTION 5  |  Medical-Surgical — Renal

A nurse is caring for a patient with acute kidney injury whose urine output has been 20 mL/hour for the past 3 hours. The most recent potassium level is 6.1 mEq/L. Which assessment finding requires the most immediate nursing action?

A.  The patient reports cramping and tingling in both hands.

B.  The patient’s blood pressure is 158/96 mmHg.

C.  The telemetry monitor shows peaked T-waves and a widening QRS complex.

D.  The patient’s weight has increased by 1.2 kg since admission.

✔  Correct Answer: C

Rationale

Peaked T-waves and widening QRS complex are the ECG manifestations of severe, immediately life-threatening hyperkalemia. Potassium of 6.1 mEq/L with these cardiac changes indicates that the elevated potassium is destabilizing the myocardial membrane and creating conditions for fatal dysrhythmias — ventricular fibrillation or asystole. This requires immediate provider notification and emergency pharmacological intervention including calcium gluconate for cardiac membrane stabilization, followed by potassium-lowering measures.

A is incorrect: Peripheral paresthesias and cramping are signs of hyperkalemia affecting neuromuscular function. They are concerning and warrant assessment, but they are less immediately life-threatening than cardiac dysrhythmia changes on telemetry.

B is incorrect: Hypertension is an expected finding in acute kidney injury due to fluid retention and renin-angiotensin activation. It requires management but is not an immediate emergency in this context compared to the cardiac rhythm changes.

D is incorrect: A 1.2 kg weight gain indicates fluid retention consistent with AKI pathophysiology. It requires assessment and management but represents a subacute concern compared to the immediate cardiac emergency of hyperkalemia-induced rhythm changes.

Questions 6–10: Pharmacology and Patient Safety

QUESTION 6  |  Pharmacology — Anticoagulants

A nurse receives an order to administer heparin 5,000 units subcutaneously to a patient admitted for a deep vein thrombosis. Before administering the medication, the nurse reviews the morning laboratory values and notes: PT 14 seconds, INR 1.1, aPTT 112 seconds, platelet count 48,000/mm3. Which action does the nurse take?

A.  Administer the heparin as ordered since it is a subcutaneous prophylactic dose.

B.  Hold the heparin, document the laboratory findings, and notify the provider before administering.

C.  Administer the heparin and notify the provider of the platelet count after administration.

D.  Reduce the heparin dose by half and proceed with administration given the critical platelet count.

✔  Correct Answer: B

Rationale

Two critical laboratory findings require provider notification before heparin administration. First, the aPTT of 112 seconds is supratherapeutic — the therapeutic target for heparin anticoagulation is 60 to 100 seconds, and 112 seconds indicates the patient is over-anticoagulated and at elevated bleeding risk. Second, a platelet count of 48,000/mm3 represents severe thrombocytopenia — either from heparin-induced thrombocytopenia (HIT), which requires immediate heparin discontinuation and alternative anticoagulation, or from another cause requiring evaluation. Administering additional heparin without provider evaluation of these values poses a serious and potentially fatal bleeding or HIT risk.

A is incorrect: The dose route does not change the safety concern. Subcutaneous heparin in the setting of supratherapeutic aPTT and severe thrombocytopenia carries the same risks as IV heparin — and the specific combination of thrombocytopenia plus heparin use requires evaluation for HIT before any further heparin exposure.

C is incorrect: Administering a potentially contraindicated medication and notifying the provider afterward reverses the correct sequence. The five rights of medication administration include the right to question orders that appear unsafe before administration — not after.

D is incorrect: A nurse does not independently adjust medication doses. Dose modifications require a provider order. Additionally, dose reduction does not address the potential HIT concern that severe thrombocytopenia in a heparin-treated patient raises.

QUESTION 7  |  Pharmacology — Psychiatric Medications

A patient with schizophrenia has been receiving haloperidol 10 mg daily for three weeks. The patient presents to the clinic with involuntary repetitive movements of the tongue, lips, and jaw, along with grimacing that the patient states has been present for several days. Which is the nurse’s priority action?

A.  Reassure the patient that these movements are a normal adjustment to antipsychotic therapy and will resolve with time.

B.  Document the findings and notify the provider, recognizing these as signs of tardive dyskinesia requiring medication evaluation.

C.  Administer a PRN dose of benztropine as prescribed, since this presentation indicates acute dystonia.

D.  Advise the patient to continue taking haloperidol and schedule a follow-up appointment in 30 days.

✔  Correct Answer: B

Rationale

The presentation describes tardive dyskinesia — a late-onset, potentially irreversible movement disorder caused by prolonged dopamine receptor blockade from antipsychotic medications. It is characterized by involuntary orofacial movements including tongue protrusion, lip smacking, grimacing, and choreiform movements, occurring after weeks to months of antipsychotic therapy. Early recognition and provider notification are critical because continuing the offending medication may worsen TD irreversibly. Management may include dose reduction, medication change to a lower-potency or atypical antipsychotic, or specific TD treatments such as valbenazine or deutetrabenazine.

A is incorrect: These movements are not a benign adjustment effect — they are signs of a potentially irreversible medication-induced movement disorder. Falsely reassuring the patient delays necessary evaluation and risks permanent neurological impairment.

C is incorrect: Benztropine is used for acute dystonia — an acute, painful muscle spasm occurring shortly after antipsychotic initiation, typically within hours to days. Tardive dyskinesia is a late-onset, non-painful, choreiform movement disorder that does not respond to anticholinergic medications and may actually worsen with them.

D is incorrect: Continuing haloperidol without evaluation in a patient with suspected tardive dyskinesia risks worsening irreversible neurological damage. This is not an appropriate independent nursing action — provider notification and medication evaluation are required immediately.

QUESTION 8  |  Patient Safety — Medication Administration

A nurse is preparing to administer a nasogastric tube feeding to a patient. After inserting the NG tube, the nurse aspirates gastric contents with a pH of 5. The chest X-ray ordered for tube confirmation has not yet been completed. Which action does the nurse take?

A.  Begin the tube feeding since a gastric aspirate pH below 6 confirms gastric placement.

B.  Attempt to auscultate air over the epigastrium to verify placement before proceeding.

C.  Wait for the chest X-ray confirmation before initiating the tube feeding.

D.  Flush the tube with 30 mL of water and begin the feeding at a reduced rate while awaiting imaging.

✔  Correct Answer: C

Rationale

Although a gastric aspirate pH below 6 is supportive of gastric placement, it is not definitive confirmation. Respiratory secretions, pleural fluid, and certain gastrointestinal conditions can produce aspirates with a pH below 6 from non-gastric locations. The gold standard for initial NG tube placement confirmation before first use is radiographic verification — a chest X-ray that visualizes the tube’s position in the stomach. Current evidence-based guidelines and institutional standards require radiographic confirmation before initiating any feeding or medication administration through a newly placed NG tube.

A is incorrect: Gastric aspirate pH below 6 is a supporting indicator but not a sole confirmation method for initial tube placement. The risk of inadvertent pulmonary feeding from a misplaced tube — which can cause aspiration pneumonia and death — requires the highest-certainty confirmation method for initial use.

B is incorrect: Auscultation of air over the epigastrium was historically used for NG tube placement verification but is no longer considered a reliable confirmation method. It has been shown to produce audible sounds even when the tube is in the lung, and major nursing organizations have removed it from placement verification protocols.

D is incorrect: Initiating feeding at a reduced rate does not reduce the risk of pulmonary administration. If the tube is misplaced in the airway, any feeding volume administered causes direct pulmonary injury. There is no safe partial approach — radiographic confirmation must precede all feeding.

QUESTION 9  |  Pharmacology — Digoxin

A nurse is preparing to administer digoxin 0.125 mg orally to a patient with heart failure. The nurse reviews the morning assessment and notes: heart rate 54 bpm, blood pressure 112/68 mmHg, potassium 3.1 mEq/L, digoxin level 1.8 ng/mL. Which action is correct?

A.  Administer the digoxin as ordered since the digoxin level is within the therapeutic range.

B.  Hold the digoxin because the heart rate is below 60 bpm and notify the provider.

C.  Hold the digoxin and notify the provider of both the bradycardia and the hypokalemia.

D.  Administer the digoxin and recheck the potassium level in four hours.

✔  Correct Answer: C

Rationale

Two concurrent findings require provider notification and justify withholding digoxin. First, a heart rate below 60 bpm is a standard parameter for holding digoxin — bradycardia is both a side effect of digoxin and a contraindication to its administration without provider reassessment. Second, and critically, a potassium level of 3.1 mEq/L represents hypokalemia, which significantly potentiates digoxin toxicity by increasing myocardial sensitivity to the drug even at therapeutic serum levels. A digoxin level of 1.8 ng/mL, while technically within the conventional therapeutic range of 0.5 to 2.0 ng/mL, becomes clinically dangerous in the setting of hypokalemia. Both findings require simultaneous provider notification before any digoxin is administered.

A is incorrect: The digoxin level being within therapeutic range does not override the clinical safety concerns of bradycardia and hypokalemia. Serum drug levels are interpreted in clinical context — a level that is technically therapeutic can produce toxicity when potassium depletion sensitizes the myocardium.

B is incorrect: Holding digoxin for bradycardia alone addresses only one of the two safety concerns. The hypokalemia is independently significant and must also be communicated to the provider — option B incompletely addresses the clinical situation.

D is incorrect: Administering digoxin to a bradycardic, hypokalemic patient and rechecking potassium in four hours is dangerous. The potassium needs to be corrected before digoxin is administered — not after, when the drug is already on board and potentially producing toxicity.

QUESTION 10  |  Patient Safety — Infection Control

A nurse is caring for a patient in airborne precautions for confirmed pulmonary tuberculosis. The patient needs to be transported to radiology for a chest CT scan. Which action is correct before transporting the patient?

A.  Place a standard surgical mask on the patient and notify radiology to prepare a negative pressure room for the scan.

B.  Place a surgical mask on the patient, notify radiology of the patient’s precaution status, and ensure transport staff wear N95 respirators.

C.  Apply an N95 respirator to the patient before transport to prevent transmission in hallways and radiology.

D.  Cancel the transport and arrange for portable imaging at the bedside to avoid exposing other patients and staff.

✔  Correct Answer: B

Rationale

For transport of a patient on airborne precautions, the patient wears a standard surgical mask — not an N95 — to contain respiratory droplets and reduce airborne particle dispersion during transport. The N95 respirator is worn by healthcare workers, not by the patient. Radiology must be notified in advance so the department can prepare for the patient’s arrival and minimize exposure time for other patients and staff. Transport personnel and receiving staff must wear N95 respirators when in proximity to the patient.

A is incorrect: Notifying radiology to prepare a negative pressure room for a CT scanner is not standard or feasible in most facilities — CT rooms are not typically negative pressure environments. The preparation involves minimizing patient flow overlap and ensuring staff protection, not room air system modification for the scan.

C is incorrect: The patient wears a surgical mask during transport — not an N95. N95 respirators are designed for healthcare worker protection and require fit-testing for proper seal. Placing an N95 on the patient does not align with infection control transport guidelines for airborne precautions.

D is incorrect: Cancelling medically necessary imaging is not appropriate unless portable imaging would provide equivalent diagnostic value. Airborne precaution patients are transported when clinically necessary — the protocol for safe transport exists precisely to enable this while protecting others.

Questions 11–15: Specialty Areas and Clinical Judgment

QUESTION 11  |  Maternal-Newborn — Fetal Monitoring

A laboring patient at 39 weeks gestation is receiving oxytocin augmentation. The fetal monitor shows a fetal heart rate of 144 bpm with moderate variability, followed by a deceleration that begins 20 seconds after the peak of a contraction, recovers slowly, and reaches a nadir of 104 bpm. Which action does the nurse take first?

A.  Continue monitoring since the deceleration pattern is consistent with early decelerations, which are benign.

B.  Reposition the patient to the left lateral position, apply oxygen at 8 to 10 L/min via non-rebreather mask, and stop the oxytocin infusion.

C.  Perform a vaginal examination to assess for umbilical cord prolapse.

D.  Increase the oxytocin infusion rate to shorten the duration of labor and reduce fetal stress.

✔  Correct Answer: B

Rationale

The deceleration described is a late deceleration — it begins after the peak of the contraction, recovers slowly, and does not mirror the contraction shape. Late decelerations indicate uteroplacental insufficiency: the placenta is unable to deliver adequate oxygen to the fetus during the contraction, and the fetal heart rate drops as a result of myocardial hypoxia. The NCLEX intervention sequence for late decelerations is: position change to left lateral (increases uterine blood flow), administer oxygen by non-rebreather mask (increases maternal-fetal oxygen gradient), stop oxytocin (removes the exacerbating factor of increased uterine activity), and IV fluid bolus to improve circulating volume and placental perfusion, followed by provider notification.

A is incorrect: Early decelerations begin at the onset of a contraction, mirror its shape, and recover by the end of the contraction — they reflect fetal head compression and are benign. This deceleration begins after the contraction peak and recovers slowly, which is the defining pattern of a late deceleration, not an early one.

C is incorrect: Vaginal examination for cord prolapse is the priority action for variable decelerations — which are abrupt, V-shaped, and associated with cord compression — not late decelerations. Performing an unnecessary vaginal examination does not address uteroplacental insufficiency.

D is incorrect: Increasing oxytocin in the setting of late decelerations directly worsens the underlying problem by increasing uterine contraction frequency and duration, further reducing placental perfusion time between contractions. Oxytocin must be stopped, not increased.

QUESTION 12  |  Mental Health — Therapeutic Communication

A nurse is caring for a patient admitted after a suicide attempt. The patient tells the nurse: I just feel like everyone would be better off without me. I have nothing left to live for. Which response by the nurse is most therapeutic?

A.  I understand how you feel. Many people go through periods like this and come out stronger on the other side.

B.  You should not say that. You have so much to live for, and your family needs you.

C.  You are feeling as though your absence would benefit the people around you. Can you tell me more about what has brought you to this point?

D.  I need to let you know that everything you share with me may be documented and shared with your care team for your safety.

✔  Correct Answer: C

Rationale

Option C uses reflection — restating the emotional content of the patient’s statement in the nurse’s own words — to demonstrate that the patient has been heard, and follows with an open-ended question that invites the patient to elaborate on their experience. This is the foundational therapeutic communication technique for patients expressing suicidal ideation: validate the feeling, do not dismiss or minimize it, and open the space for further expression. This approach builds therapeutic alliance, provides the nurse with additional clinical data about the patient’s current risk state, and keeps the patient engaged in the conversation rather than shutting down.

A is incorrect: Saying I understand how you feel when you do not have the patient’s experience is a form of false empathy, and the statement that things will get better is false reassurance — a blocking technique that minimizes the patient’s current experience and may cause them to disengage from the conversation.

B is incorrect: You should not feel that way and you have so much to live for are invalidating responses that dismiss the patient’s expressed experience and impose the nurse’s perspective. This blocks therapeutic communication and may cause the patient to feel judged and misunderstood — increasing rather than decreasing isolation.

D is incorrect: While safety planning and confidentiality limits are important topics to address, delivering a documentation and sharing disclosure as the first response to a patient expressing suicidal hopelessness is clinically inappropriate. It shifts focus from the patient’s emotional state to legal/procedural concerns at the most vulnerable moment and disrupts the formation of therapeutic alliance.

QUESTION 13  |  Medical-Surgical — Respiratory

A nurse is caring for a patient with asthma who is in moderate respiratory distress. The patient has received two doses of albuterol via nebulizer 20 minutes apart. The nurse reassesses and finds: respiratory rate 32 breaths/min, oxygen saturation 91%, use of accessory muscles, and the patient is now speaking in one to two word sentences. Auscultation reveals significantly diminished breath sounds bilaterally with no wheezing. Which finding is most concerning?

A.  The persistent use of accessory muscles despite two albuterol treatments.

B.  The oxygen saturation remaining at 91% after bronchodilator therapy.

C.  The absence of wheezing with severely diminished breath sounds bilaterally.

D.  The patient’s inability to speak in full sentences.

✔  Correct Answer: C

Rationale

The absence of wheezing in a patient with worsening asthma is a critical danger sign, not a reassuring one. Wheezing requires sufficient airflow to produce sound. When wheezing disappears in a worsening asthmatic patient — particularly when accompanied by severely diminished breath sounds — it indicates a silent chest: airflow has become so severely restricted that there is no longer enough movement to generate wheeze sounds. A silent chest in an asthmatic patient indicates impending respiratory failure and requires immediate emergency intervention including high-dose bronchodilators, systemic corticosteroids, and preparation for possible intubation and mechanical ventilation.

A is incorrect: Persistent accessory muscle use is concerning and indicates ongoing respiratory distress, but it is an expected finding in a patient who has not yet responded to bronchodilator therapy. It is less acutely dangerous than the silent chest finding.

B is incorrect: An oxygen saturation of 91% after two albuterol treatments indicates inadequate response to therapy and requires escalation of care, but it is a quantitative finding that provides less immediate information about the severity of airflow obstruction than the auscultation finding of absent breath sounds.

D is incorrect: One to two word speech is a clinical marker of severe dyspnea and indicates significant respiratory distress, but it is a functional consequence of respiratory effort — the silent chest finding directly indicates the underlying mechanism of impending respiratory collapse.

QUESTION 14  |  NGN Bow Tie — Clinical Judgment

A nurse is caring for a 78-year-old patient who was admitted 24 hours ago for a urinary tract infection and is receiving IV ceftriaxone. The patient was alert and oriented on admission. The nurse enters the room and finds the patient pulling at the IV tubing, unable to state the current year, calling out for a deceased family member, and with a heart rate of 108 and temperature of 38.9 degrees Celsius.

For this NGN Bow Tie question, identify the following:

Most likely condition: Delirium superimposed on acute infection (sepsis-related delirium in an elderly patient)

Two priority nursing actions:

1. Perform a full safety assessment — lower the bed to its lowest position, raise side rails, remove the patient’s hands from the IV tubing, and activate a bed exit alarm.

2. Notify the provider of the acute change in mental status and the elevated vital signs, which together meet criteria for clinical deterioration potentially indicating sepsis progression.

Two parameters to monitor:

1. Neurological status — serial cognitive assessments using the Confusion Assessment Method (CAM) to track the trajectory of the delirium.

2. Vital signs and sepsis indicators — temperature trend, heart rate, blood pressure, respiratory rate, and urine output to monitor for progression to septic shock.

Rationale

Acute-onset confusion in an elderly patient with an active infection and new vital sign changes — tachycardia and fever — constitutes a medical emergency requiring immediate safety intervention and provider notification. Delirium in elderly patients is associated with significantly increased mortality, prolonged hospitalization, and risk of long-term cognitive decline. The combination of acute confusion, tachycardia, and fever in an infection context requires rapid assessment for sepsis progression. Safety is the immediate nursing priority, but it must be concurrent with clinical escalation — not sequential.

QUESTION 15  |  Medical-Surgical — Post-Operative

A nurse receives a patient in the PACU who is 45 minutes post-general anesthesia following an open bowel resection. The patient is arousable but difficult to keep awake, respiratory rate is 8 breaths/min, oxygen saturation is 90% on 6 L/min nasal cannula, and the patient’s pupils are pinpoint bilaterally. Which action does the nurse take first?

A.  Apply a non-rebreather mask at 15 L/min and elevate the head of bed to 30 degrees.

B.  Stimulate the patient by calling their name loudly and applying a sternal rub.

C.  Administer naloxone per the standing post-operative opioid reversal protocol.

D.  Notify the anesthesiologist and document the findings while continuing to monitor.

✔  Correct Answer: C

Rationale

The clinical triad of respiratory depression (rate 8/min), decreased level of consciousness refractory to stimulation, and pinpoint pupils in a post-operative patient who recently received general anesthesia is the classic presentation of opioid-induced respiratory depression. Pinpoint pupils are the pathognomonic finding — they reflect excessive parasympathetic tone from opioid receptor activation at the midbrain. This is a pharmacological emergency requiring immediate administration of naloxone, an opioid antagonist, which will rapidly reverse respiratory depression, improve consciousness, and restore normal pupil size. Delay in administering naloxone risks hypoxic brain injury or respiratory arrest.

A is incorrect: Increasing supplemental oxygen addresses the hypoxia symptomatically but does not reverse the underlying cause — opioid-induced respiratory center suppression. A patient with a respiratory rate of 8 and CNS depression is not protecting their airway adequately; oxygenation improvement without ventilatory drive restoration is insufficient.

B is incorrect: Attempting to stimulate the patient may briefly increase consciousness but will not reverse opioid-induced respiratory depression. The physiological cause — opioid receptor binding — is not addressed by physical stimulation, and the respiratory rate and pupil findings indicate pharmacological rather than behavioral sedation.

D is incorrect: Notifying the anesthesiologist is necessary and will occur, but it is not the first action. Naloxone is a standing post-operative protocol medication specifically for this clinical situation, and the nurse administers it immediately while simultaneously notifying the provider — not after documenting and waiting.

Scoring and Performance Analysis

After completing all 15 questions of this NCLEX practice test, calculate your score and use the performance analysis framework below to extract maximum preparation value from your results.

Score Interpretation

• 13 to 15 correct: Strong clinical judgment performance. Review the rationales for any missed questions and identify whether errors were knowledge-based or reasoning-based. Focus remaining preparation on NGN format fluency and mixed-content simulation building.
• 10 to 12 correct: Solid foundation with identifiable gaps. Review all missed rationale explanations carefully. Identify which content categories produced the most errors and increase targeted question bank practice in those areas.
• 7 to 9 correct: Foundational reasoning patterns need strengthening. For each missed question, identify the specific error type — wrong process step, wrong priority framework, or clinical knowledge gap. Content areas with multiple missed questions require dedicated review book study before additional question practice.
• Below 7 correct: Significant preparation gaps exist across multiple areas. Use this NCLEX practice test result to identify your three weakest content categories and build a revised study schedule that prioritizes those areas with active recall content review before returning to practice questions.

Error Pattern Analysis

Regardless of your total score, categorize each incorrect answer from this NCLEX practice test by the reasoning error that produced it. If you selected the right action at the wrong nursing process step — an implementation answer when assessment was correct — that is a process sequencing error. If you selected the correct treatment for the wrong patient — a COPD intervention on an asthma question — that is a patient-context error. If you did not recognize the clinical significance of a specific finding — missed the significance of absent wheezing or pinpoint pupils — that is a clinical knowledge gap. The category that produces the most of your incorrect answers is the preparation target that will produce the fastest performance improvement on your next NCLEX practice test and on the actual exam.

Conclusion

This NCLEX practice test is designed to do more than measure what you currently know — it is designed to develop the clinical reasoning habits that produce correct answers consistently on the most difficult questions the exam delivers. The 15 questions above span the highest-yield content categories, include a Next Generation NCLEX bow tie format, and are constructed at the application and analysis cognitive levels that the CAT algorithm targets when assessing clinical judgment competency.

If you completed this NCLEX practice test using the two-read discipline, the pre-answer generation method, and the full rationale review for every question, you have built clinical reasoning experience equivalent to a deliberate practice session — not just an accuracy check. The candidates who improve most rapidly on the NCLEX are not the ones who answer the most questions but the ones who extract the most learning from each question they complete. Return to this NCLEX practice test in two weeks and measure whether your score and your error pattern have changed — that trajectory is the most meaningful indicator of preparation progress.
