Complete NCLEX-RN Quiz Bank
Prepare for the NCLEX-RN exam with a complete set of topic-wise practice quizzes covering all major nursing categories. From Safe & Effective Care to Pharmacology, Pediatrics, Mental Health, and more — each quiz is designed to match the latest exam blueprint with 25 high-quality questions
Question 1: A nurse is caring for four patients. Which patient should the nurse assess FIRST?
Answer: D — Airway and breathing always come first (ABCs). A respiratory rate of 10 with SpO2 of 85 percent indicates respiratory compromise requiring immediate intervention. The other findings are important but not immediately life-threatening.
Question 2: A patient is being discharged on warfarin therapy. Which statement indicates the patient needs FURTHER teaching?
Answer: A — Ibuprofen and all NSAIDs increase bleeding risk when combined with warfarin. Patients must avoid NSAIDs and use acetaminophen instead. The other statements reflect correct understanding of warfarin safety precautions.
Question 3: Which action by a newly licensed nurse requires the charge nurse to intervene?
Answer: D — Raising all four side rails is considered a restraint and requires a physician order. This is a patient safety and legal violation. The charge nurse must intervene immediately. The other actions reflect appropriate nursing practice.
Question 4: A nurse suspects a colleague is diverting controlled substances. The MOST appropriate action is to:
Answer: C — Suspected drug diversion must be reported through proper channels (nurse manager, supervisor, or compliance hotline) to protect patients. Ignoring it endangers patients. Confronting or gossiping is inappropriate and may compromise the investigation.
Question 5: A patient with a latex allergy is scheduled for surgery. Which action is MOST important for the nurse to take?
Answer: C — Ensuring a latex-free environment is the priority to prevent a potentially fatal anaphylactic reaction. All latex-containing products must be removed and replaced with non-latex alternatives before the patient enters the OR.
Question 6: A nurse receives a telephone order from a physician. The CORRECT action is to:
Answer: D — Read-back verification is a required patient safety practice for telephone and verbal orders. The nurse reads the complete order back to the physician to confirm accuracy, then documents it with date, time, and the prescriber name.
Question 7: A patient signs an informed consent form for surgery. Which situation would make this consent INVALID?
Answer: C — Informed consent requires the patient to be competent and free from mind-altering substances. Signing after receiving IV sedation invalidates the consent because the patient cannot make a fully informed, rational decision.
Question 8: A home health nurse visits an elderly patient who reports using herbal supplements. Which response is MOST appropriate?
Answer: C — Herbal supplements can interact dangerously with prescribed medications. The nurse should document all supplements and alert the provider. Many herbs affect bleeding, blood pressure, blood sugar, and drug metabolism.
Question 9: A nurse is teaching a 55-year-old patient about recommended health screenings. Which screening should the nurse recommend?
Answer: B — Current guidelines recommend colorectal cancer screening beginning at age 45 for average-risk individuals. Options include colonoscopy every 10 years or annual stool-based tests. Earlier screening is indicated for those with risk factors.
Question 10: A patient newly diagnosed with type 2 diabetes asks the nurse about lifestyle modifications. The BEST initial response is:
Answer: C — Lifestyle modifications (exercise, balanced diet, weight management) are the cornerstone of type 2 diabetes management. Carbohydrates are managed, not eliminated. Medication may be added later but lifestyle changes are always the first intervention.
Question 11: A 50-year-old male patient has no significant medical history. The nurse should recommend which immunization?
Answer: A — Adults need annual influenza vaccines, Td/Tdap boosters every 10 years, and additional vaccines based on age, health conditions, and risk factors. The nurse should assess immunization history and recommend accordingly.
Question 12: A nurse is teaching a patient about preventing osteoporosis. Which statement by the patient indicates understanding?
Answer: A — Weight-bearing exercise and adequate calcium and vitamin D intake are key prevention strategies for osteoporosis. Both men and women are at risk. Supplements should be discussed with the provider to determine appropriate dosing.
Question 13: A nurse is performing a community health screening. Which finding requires IMMEDIATE referral?
Answer: B — A new breast lump requires immediate referral for diagnostic evaluation (mammogram, ultrasound, possible biopsy) to rule out malignancy. The other findings are either slightly elevated or within normal limits and do not require urgent referral.
Question 14: A patient tells the nurse that they have been feeling hopeless and have thought about ending their life. The PRIORITY nursing action is:
Answer: C — When a patient expresses suicidal ideation, the nurse must immediately perform a direct safety assessment by asking about a specific plan, means, and intent. This does not increase suicide risk - it opens critical dialogue and allows for immediate safety interventions.
Question 15: A patient with schizophrenia tells the nurse that the CIA is monitoring them through the television. The BEST therapeutic response is:
Answer: B — Acknowledge the patient feelings without reinforcing or arguing with the delusion. Saying it must be frightening validates the emotional experience while providing reassurance of safety. Arguing or agreeing with delusions is not therapeutic.
Question 16: A nurse is assessing a patient for signs of alcohol withdrawal. Which finding is MOST concerning?
Answer: D — Seizures with hallucinations and confusion indicate severe alcohol withdrawal (delirium tremens), which is a medical emergency with significant mortality risk. This requires immediate intervention including IV benzodiazepines, seizure precautions, and close monitoring.
Question 17: A patient with major depressive disorder is suddenly cheerful and gives away personal belongings. The nurse should:
Answer: B — A sudden mood improvement with giving away possessions is a classic warning sign that a patient has decided to act on a suicide plan and feels relieved. The nurse must immediately increase the level of observation and notify the provider.
Question 18: A patient in sickle cell crisis reports severe pain rated 10 out of 10. The nurse should FIRST:
Answer: B — Sickle cell pain crisis causes severe vaso-occlusive pain requiring prompt opioid administration. Pain is what the patient says it is. Delaying treatment or questioning the patient report is inappropriate. Cold application worsens sickling and is contraindicated.
Question 19: A patient with heart failure is being discharged on furosemide. Which instruction is MOST important?
Answer: C — Daily weights are the most sensitive indicator of fluid retention in heart failure. A weight gain of 2 pounds in one day (or 5 pounds in one week) suggests fluid overload requiring provider notification. Take diuretics in the morning, not bedtime, to avoid nocturia.
Question 20: A nurse is caring for a patient in diabetic ketoacidosis (DKA). Which findings does the nurse expect?
Answer: D — DKA presents with Kussmaul respirations (deep, rapid breathing to blow off CO2), fruity acetone breath (from ketone production), hyperglycemia above 300 mg/dL, dehydration, and metabolic acidosis. Treatment includes IV insulin, fluids, and electrolyte replacement.
Question 21: A patient develops sudden onset of chest pain, dyspnea, and a unilateral swollen calf. The nurse should suspect:
Answer: D — The triad of sudden chest pain, dyspnea, and unilateral calf swelling strongly suggests a pulmonary embolism from a DVT. This is a life-threatening emergency. Notify the provider immediately and prepare for anticoagulation therapy and diagnostic imaging.
Question 22: A patient with chronic kidney disease has a potassium level of 6.8 mEq/L. The nurse should:
Answer: D — Normal potassium is 3.5 to 5.0 mEq/L. A level of 6.8 is critically elevated and can cause fatal cardiac arrhythmias (peaked T waves, widened QRS, ventricular fibrillation). Expect orders for IV calcium gluconate, insulin with glucose, and possible dialysis.
Question 23: A patient is admitted with syndrome of inappropriate antidiuretic hormone (SIADH). The nurse expects to find:
Answer: D — SIADH causes excessive ADH secretion leading to water retention, dilutional hyponatremia, and concentrated urine despite low serum osmolality. Treatment includes fluid restriction, hypertonic saline for severe cases, and addressing the underlying cause.
Question 24: A patient with cirrhosis develops confusion and asterixis (liver flap). The nurse suspects:
Answer: C — Confusion and asterixis (flapping hand tremor) in a cirrhosis patient are hallmark signs of hepatic encephalopathy caused by the liver inability to clear ammonia. Expect orders for lactulose (to excrete ammonia via stool) and rifaximin.
Question 25: A patient is receiving a blood transfusion and develops fever, chills, back pain, and dark urine 15 minutes after initiation. The nurse should FIRST:
Answer: B — These are signs of a hemolytic transfusion reaction - a life-threatening emergency. Stop the transfusion immediately, maintain IV access with NS, notify the provider and blood bank, send the blood bag and blood samples for analysis, and monitor for shock and renal failure.
Question 26: A nurse is administering metoprolol (a beta-blocker). Before giving the medication, the nurse should:
Answer: A — Beta-blockers decrease heart rate and blood pressure. Always check apical pulse for 60 seconds and BP before administration. Hold the dose and notify the provider if HR is below 60 bpm or systolic BP is below 90 mmHg.
Question 27: A patient is prescribed enoxaparin (Lovenox) subcutaneously. The nurse should administer the injection:
Answer: B — Enoxaparin is given subcutaneously in the abdomen (at least 2 inches from the umbilicus). Do NOT aspirate before injection or massage afterward, as this causes bruising and hematoma formation at the injection site. Rotate injection sites.
Question 28: A patient on phenytoin (Dilantin) reports gum overgrowth and has difficulty maintaining balance. The nurse should:
Answer: D — Gingival hyperplasia and ataxia (balance difficulty) are known phenytoin side effects. Ataxia may indicate toxicity (therapeutic level 10-20 mcg/mL). Check the serum level. Teach meticulous oral hygiene for gum overgrowth. Notify the provider for dose evaluation.
Question 29: A nurse is preparing to administer IV potassium chloride. Which action is ESSENTIAL?
Answer: C — IV potassium must NEVER be given by IV push - it causes fatal cardiac arrest. Always dilute, use an infusion pump, and limit the rate to 10 mEq/hour peripherally. Monitor the IV site, cardiac rhythm, and serum potassium levels.
Question 30: A patient receiving morphine has a respiratory rate of 8 and is difficult to arouse. After stopping the morphine, the nurse should prepare to administer:
Answer: D — Naloxone (Narcan) is the opioid antagonist that reverses morphine-induced respiratory depression. Flumazenil reverses benzodiazepines, protamine reverses heparin, and vitamin K reverses warfarin. Knowing each antidote is critical for NCLEX.
Question 31: A nurse is teaching a patient about reducing the risk of deep vein thrombosis (DVT) after surgery. Which instruction is MOST important?
Answer: C — Early ambulation, ankle pumps, and calf exercises promote venous return and prevent blood stasis that leads to DVT formation. Compression stockings and anticoagulant prophylaxis may also be ordered. Bed rest and leg crossing increase DVT risk.
Question 32: A patient is scheduled for a cardiac catheterization. Which assessment is MOST important before the procedure?
Answer: B — Cardiac catheterization uses iodine-based contrast dye. Allergy to iodine, contrast, or shellfish increases the risk of an anaphylactic reaction. The provider must be notified so premedication with steroids and antihistamines can be ordered.
Question 33: A patient has a chest tube connected to a water-seal drainage system. The nurse observes continuous bubbling in the water-seal chamber. This indicates:
Answer: A — Continuous bubbling in the water-seal chamber indicates an air leak - either from the patient lung (persistent pneumothorax) or from a connection leak in the tubing system. The nurse should check all connections, assess the patient respiratory status, and notify the provider.
Question 34: A nurse is performing a neurological assessment and notes that the patient pupils are fixed and dilated bilaterally. This finding suggests:
Answer: A — Fixed, dilated pupils bilaterally indicate a neurological emergency - most likely severely elevated intracranial pressure with brainstem compression. This is a life-threatening finding. Notify the provider immediately and prepare for emergency interventions.
Question 35: A nurse suspects a patient is developing sepsis. Which assessment findings support this suspicion?
Answer: D — Sepsis presents with fever (or hypothermia), tachycardia, hypotension, and altered mental status. The SIRS criteria include temperature above 100.4 or below 96.8, heart rate above 90, respiratory rate above 20, and WBC abnormalities. Early recognition saves lives.
Question 36: A nurse is caring for a patient with a new tracheostomy. Which item should ALWAYS be kept at the bedside?
Answer: D — A spare tracheostomy tube (one size smaller for easier insertion) and the obturator must always be at the bedside in case of accidental decannulation. This is a life-threatening airway emergency that requires immediate tube replacement.
Question 37: A nurse is caring for four patients with potential infectious conditions. Which patient requires AIRBORNE precautions?
Answer: B — Active pulmonary TB requires airborne precautions: negative-pressure isolation room and N95 respirator. MRSA requires contact precautions. C. difficile requires contact precautions with soap-and-water handwashing. Influenza requires droplet precautions.
Question 38: A nurse is caring for a patient with a central venous catheter. Which finding indicates a possible catheter-related bloodstream infection?
Answer: A — Fever, chills, and insertion site redness are classic signs of a central line-associated bloodstream infection (CLABSI). The nurse should obtain blood cultures (from the line and peripherally), notify the provider, and anticipate catheter removal and antibiotic therapy.
Question 39: A nurse accidentally sustains a needlestick from a needle used on an HIV-positive patient. The FIRST action is to:
Answer: C — Needlestick from an HIV-positive source requires immediate action: wash the site, report to the supervisor, and go to the ED for post-exposure prophylaxis (PEP) evaluation. PEP must be started within 2 hours (ideally within 72 hours) for maximum effectiveness.
Question 40: A patient has been on contact precautions for C. difficile. The nurse should perform hand hygiene using:
Answer: C — C. difficile produces spores that are resistant to alcohol-based sanitizers. Only thorough handwashing with soap and water physically removes the spores. This is a critical exception to the general preference for alcohol-based hand hygiene in healthcare.
Question 41: A patient develops hives, wheezing, and hypotension during an IV antibiotic infusion. The nurse should FIRST:
Answer: C — These are signs of anaphylaxis - a life-threatening allergic reaction. Stop the causative agent immediately, maintain IV access, call for help, prepare epinephrine, and monitor airway, breathing, and circulation. Every second of delay increases mortality risk.
Question 42: A charge nurse must assign four patients. Which patient is MOST appropriate to assign to an experienced LPN/LVN?
Answer: A — LPNs can perform routine care on stable patients including tracheostomy suctioning. Discharge teaching on new complex medications, initial comprehensive assessments, and post-procedure assessments with unstable potential require RN-level judgment and scope of practice.
Question 43: A charge nurse receives report on four patients. Which patient should be assessed FIRST?
Answer: B — Increasing dyspnea and audible wheezing in an asthma patient indicates worsening airway obstruction that can progress to respiratory failure. ABCs (airway, breathing, circulation) always take priority. The other patients have expected or non-urgent findings.
Question 44: A nurse delegates the task of obtaining vital signs on a stable patient to a UAP (unlicensed assistive personnel). Which instruction is MOST appropriate?
Answer: C — When delegating, the RN must provide clear instructions and require the UAP to report ALL results back. The RN retains accountability for assessment and documentation. Telling the UAP to report only abnormal findings is unsafe because they may not recognize abnormalities.
Question 45: An RN is supervising a new graduate nurse. The new nurse prepares to administer insulin without having another nurse verify the dose. The RN should:
Answer: A — Insulin is a high-alert medication requiring independent double verification before administration per most facility policies. The RN must intervene before the medication is given to prevent a potentially dangerous dosing error.
Question 46: A charge nurse must decide which task can be delegated to a UAP. Which task is appropriate?
Answer: B — Obtaining fingerstick blood glucose is a routine, standardized task within UAP scope after proper training. Assessment, education, and care planning require RN clinical judgment and cannot be delegated to unlicensed personnel.
Question 47: A nurse must prioritize care for four patients. Which situation can the nurse address LAST?
Answer: C — Requesting a warm blanket is a comfort measure that can wait. Choking (airway obstruction), hemorrhage (circulation), and chest pain (possible MI) are all emergencies that must be addressed before comfort needs.
Question 48: A post-operative patient has not voided 8 hours after surgery. The nurse should FIRST:
Answer: A — Eight hours without voiding post-operatively requires assessment for urinary retention. Try non-invasive measures first: palpate for bladder distention, assist to bathroom, run warm water, pour warm water over the perineum. Catheterize only if these fail.
Question 49: A nurse is caring for a patient with a new colostomy. During the first assessment, the nurse notes the stoma is dark red and moist. This finding indicates:
Answer: A — A healthy stoma should be beefy red, moist, and slightly raised. Dark red and moist is normal. A pale, dusky, blue, or black stoma indicates impaired blood supply (ischemia/necrosis) and requires immediate provider notification.
Question 50: A patient is 12 hours post-thyroidectomy. Which assessment finding requires IMMEDIATE action?
Answer: A — Perioral tingling, fingertip numbness, and positive Chvostek sign (facial twitching when tapping the facial nerve) indicate hypocalcemia from accidental parathyroid removal or damage during thyroidectomy. This can progress to laryngospasm and seizures. IV calcium gluconate must be available.
Question 51: A nurse is assessing a patient with suspected appendicitis. Which finding is MOST consistent with this diagnosis?
Answer: B — McBurney point tenderness (right lower quadrant, one-third of the distance from the right anterior superior iliac spine to the umbilicus) with rebound tenderness is the classic presentation of appendicitis. Do not apply heat - this can cause rupture.
Question 52: A nurse is caring for a patient with a hip fracture who is in Buck traction. Which finding requires IMMEDIATE intervention?
Answer: B — A rope caught in the pulley disrupts the traction mechanism and can cause improper alignment, pressure injury, or loss of fracture reduction. Weights should hang freely, ropes should move smoothly through pulleys, and the patient should maintain proper alignment at all times.
Question 53: A patient with COPD is receiving oxygen at 2 L/min via nasal cannula. The patient SpO2 is 91 percent. A new nurse plans to increase the oxygen to 6 L/min. The experienced nurse should:
Answer: D — COPD patients may rely on hypoxic drive for breathing stimulus. High-flow oxygen can suppress this drive, leading to CO2 retention and respiratory failure. Low-flow oxygen (1-2 L/min) targeting SpO2 of 88-92 percent is appropriate for most COPD patients.
Question 54: A nurse is caring for a patient receiving total parenteral nutrition (TPN). The current bag is empty and the next bag is not available from pharmacy. The nurse should:
Answer: D — Abruptly stopping TPN causes rebound hypoglycemia because the pancreas is producing high insulin levels in response to the concentrated dextrose in TPN. Hanging D10W provides glucose to prevent a dangerous blood sugar crash until the new TPN bag arrives.
Question 55: A patient in labor is having contractions every 2 minutes lasting 90 seconds. The fetal heart rate tracing shows late decelerations. The nurse should FIRST:
Answer: D — Late decelerations indicate uteroplacental insufficiency - the fetus is not receiving adequate oxygen. Immediate interventions include left lateral positioning (improves placental blood flow), oxygen administration, IV fluid bolus, stopping oxytocin if running, and notifying the provider urgently.
Question 56: A nurse is assessing a newborn at 1 minute after birth. The baby has a heart rate of 110, slow irregular respirations, some flexion, grimaces when stimulated, and the body is pink with blue extremities. The APGAR score is:
Answer: D — APGAR scoring: Heart rate above 100 = 2, Slow respirations = 1, Some flexion = 1, Grimace = 1, Pink body with blue extremities (acrocyanosis) = 1. Total = 7. A score of 7 to 10 is considered normal. Below 7 requires intervention.
Question 57: A nurse is teaching a postpartum patient about warning signs to report. Which symptom requires IMMEDIATE medical attention?
Answer: A — Soaking more than one pad per hour or passing large clots indicates postpartum hemorrhage - the leading cause of maternal death worldwide. The patient should seek emergency care immediately. Causes include uterine atony, retained placenta, and lacerations.
Question 58: A nurse assesses a pregnant patient at 36 weeks gestation who reports a sudden gush of painless bright red vaginal bleeding. The nurse should suspect:
Answer: D — Painless, bright red vaginal bleeding in the third trimester is the classic presentation of placenta previa (placenta covering the cervical os). NEVER perform a vaginal exam - this can trigger life-threatening hemorrhage. Notify the provider and prepare for ultrasound.
Question 59: A postpartum nurse notes that a patient uterus is boggy and displaced to the right. The FIRST action is to:
Answer: B — A boggy uterus displaced to the right is most commonly caused by a full bladder preventing the uterus from contracting properly. Have the patient void first, then assess the fundus. If it remains boggy after bladder emptying, massage the fundus and notify the provider.
Question 60: A 3-year-old child is admitted with suspected epiglottitis. The nurse should:
Answer: B — Epiglottitis is a life-threatening airway emergency. NEVER examine the throat with a tongue depressor - this can trigger complete airway obstruction. Keep the child calm and in an upright position, maintain a quiet environment, and have emergency airway equipment immediately available.
Question 61: A nurse is assessing a 6-month-old infant. Which finding requires IMMEDIATE intervention?
Answer: A — A bulging fontanelle with a high-pitched cry in an infant indicates increased intracranial pressure, possibly from meningitis or hydrocephalus. This is a medical emergency. Normal fontanelle should be flat and soft when the infant is calm and upright.
Question 62: A 5-year-old is prescribed amoxicillin for otitis media. The parent asks why the child should finish all the medication even if they feel better. The BEST response is:
Answer: A — Incomplete antibiotic courses allow surviving bacteria (the most resistant ones) to multiply, increasing the risk of antibiotic-resistant infections and recurrence. The full prescribed course must be completed even after symptoms resolve.
Question 63: A nurse is assessing an 8-year-old with a new diagnosis of type 1 diabetes. The child is confused, pale, diaphoretic, and trembling. The blood glucose is 52 mg/dL. The nurse should FIRST:
Answer: A — Blood glucose of 52 with confusion, pallor, and diaphoresis indicates hypoglycemia requiring immediate treatment. Give 15 grams of fast-acting carbohydrate (juice, glucose tablets), wait 15 minutes, and recheck. Insulin would worsen hypoglycemia and is contraindicated.
Question 64: A child is brought to the emergency department with a suspected ingestion of a household chemical. The parent asks if they should induce vomiting. The nurse should advise:
Answer: B — Inducing vomiting is contraindicated for many ingestions (caustic substances, hydrocarbons, sharp objects) as it causes additional esophageal and airway damage. Contact Poison Control for specific guidance based on the substance ingested. Syrup of ipecac is no longer recommended.
Question 65: A patient with bipolar disorder in the manic phase has not slept in 3 days and is pacing the hallway making grandiose statements. The PRIORITY nursing intervention is:
Answer: A — During mania, priorities are safety, nutrition, and rest. Provide a calm, low-stimulation environment to reduce agitation. Offer high-calorie finger foods (the patient will not sit for meals). Set firm, consistent limits. Avoid arguing with grandiose beliefs.
Question 66: A nurse is caring for a patient experiencing a panic attack. Which intervention is MOST therapeutic?
Answer: C — During a panic attack, the nurse should stay with the patient (never leave them alone), maintain a calm demeanor, speak slowly and simply, and guide controlled breathing to reduce hyperventilation. Telling someone to calm down is dismissive and ineffective.
Question 67: A patient on a psychiatric unit refuses to take their prescribed antipsychotic medication. The nurse should:
Answer: A — Competent patients have the legal right to refuse medication. The nurse must respect this right, document the refusal, educate the patient about consequences of non-adherence, and notify the provider. Forcing or hiding medication is assault and a violation of patient rights.
Question 68: A nurse receives the following lab results for a patient on heparin therapy. Which value should be reported to the provider IMMEDIATELY?
Answer: C — A platelet count of 42,000 (normal 150,000-400,000) in a patient on heparin indicates possible heparin-induced thrombocytopenia (HIT) - a serious, potentially fatal complication. The nurse must stop heparin immediately, notify the provider, and anticipate switching to an alternative anticoagulant.
Question 69: A patient has the following arterial blood gas results: pH 7.30, PaCO2 50 mmHg, HCO3 24 mEq/L. This indicates:
Answer: D — pH 7.30 is acidotic (below 7.35). PaCO2 of 50 is elevated (above 45), which causes acidosis. HCO3 of 24 is normal (22-26), meaning the kidneys have not yet compensated. This is uncompensated respiratory acidosis, commonly caused by COPD, respiratory depression, or airway obstruction.
Question 70: A patient with heart failure has the following lab result: BNP (B-type natriuretic peptide) of 850 pg/mL. This indicates:
Answer: B — BNP above 100 pg/mL suggests heart failure; above 400 strongly indicates it. A BNP of 850 indicates significant ventricular volume overload and stretching. BNP is used to diagnose heart failure, evaluate severity, and monitor treatment response.
Question 71: A patient on digoxin has the following lab values: digoxin level 2.4 ng/mL, potassium 3.2 mEq/L. The nurse should:
Answer: D — Therapeutic digoxin level is 0.5-2.0 ng/mL; this patient is at 2.4 (toxic). Low potassium (3.2, normal 3.5-5.0) significantly increases digoxin toxicity risk because potassium and digoxin compete for the same cardiac binding sites. Hold digoxin, notify provider, and replace potassium.
Question 72: A patient has the following ABG results: pH 7.48, PaCO2 38 mmHg, HCO3 32 mEq/L. This indicates:
Answer: B — pH 7.48 is alkalotic (above 7.45). PaCO2 of 38 is normal (35-45), so the respiratory system is not the primary cause. HCO3 of 32 is elevated (above 26), which causes alkalosis. This is metabolic alkalosis, commonly caused by vomiting, NG suction, or excessive antacid use.
Question 73: A patient has a serum sodium level of 118 mEq/L. The nurse should FIRST:
Answer: C — Sodium of 118 is critically low (severe hyponatremia; normal 135-145). Severe hyponatremia causes cerebral edema and can trigger seizures, coma, and death. Implement seizure precautions, perform a neurological assessment, notify the provider, and anticipate fluid restriction or cautious hypertonic saline administration.
Question 74: A patient with a history of peptic ulcer disease reports sudden severe abdominal pain that is rigid and board-like on palpation. The nurse should suspect:
Answer: A — A rigid, board-like abdomen with sudden severe pain indicates peritonitis from a perforated ulcer. This is a surgical emergency. Position the patient upright, start IV access, keep NPO, and notify the surgeon immediately.
Question 75: A patient is admitted with acute pancreatitis. Which nursing intervention is the PRIORITY?
Answer: B — Acute pancreatitis requires pancreatic rest (NPO), aggressive IV hydration, and effective pain management. Position the patient in a side-lying or fetal position for comfort. Oral feeding worsens inflammation by stimulating pancreatic enzyme secretion.
Question 76: A patient with Addison disease is admitted with a blood pressure of 76/50 and serum sodium of 126 mEq/L. The nurse recognizes this as:
Answer: C — Addisonian crisis (acute adrenal insufficiency) presents with severe hypotension, hyponatremia, hyperkalemia, and hypoglycemia. It is life-threatening and requires immediate IV hydrocortisone, normal saline fluid resuscitation, and vasopressors if needed.
Question 77: A nurse is caring for a patient who had a stroke 2 hours ago. The provider orders alteplase (tPA). The nurse knows this medication must be administered within:
Answer: C — Alteplase (tPA) is a thrombolytic that dissolves the clot causing ischemic stroke. It must be given within 4.5 hours of symptom onset to be effective. Beyond this window, the risk of hemorrhagic transformation outweighs the benefit.
Question 78: A nurse discovers that a medication error has occurred but no harm came to the patient. The nurse should:
Answer: A — All medication errors must be reported regardless of whether harm occurred. Incident reports help identify system failures and prevent future errors. Near-miss reporting is essential for patient safety improvement and is not used for punitive action.
Question 79: A patient with limited English proficiency needs informed consent for a procedure. The nurse should:
Answer: B — Certified medical interpreters must be used for informed consent to ensure accurate and complete communication. Family members may omit information, lack medical vocabulary, or have conflicts of interest that compromise the consent process.
Question 80: A patient is scheduled for a lumbar puncture. Which position should the nurse assist the patient into?
Answer: D — The lateral recumbent (fetal) position with knees drawn up and chin tucked maximally opens the intervertebral spaces for needle insertion during lumbar puncture. An alternative is sitting upright leaning over a bedside table. Post-procedure: keep flat to prevent spinal headache.
Question 81: A nurse is donning PPE to enter the room of a patient on airborne precautions for tuberculosis. Which type of respiratory protection is required?
Answer: D — Airborne precautions for TB require an N95 respirator individually fit-tested to ensure a proper seal. Standard surgical masks do not filter the tiny airborne droplet nuclei that carry TB bacteria. The patient must be in a negative-pressure isolation room.
Question 82: Four patients ring their call lights simultaneously. Which patient should the nurse see FIRST?
Answer: A — Feeling of chest pressure with dyspnea suggests a possible myocardial infarction or pulmonary embolism - both are life-threatening emergencies. ABCs (airway, breathing, circulation) always take priority over comfort and informational requests.
Question 83: A patient is started on an SSRI antidepressant. The nurse should teach the patient that:
Answer: A — SSRIs require 2 to 4 weeks to reach full therapeutic effect. Patients must not stop abruptly as this causes discontinuation syndrome (dizziness, nausea, anxiety, flu-like symptoms). Monitor closely for increased suicidal ideation in the first weeks, especially in young adults.
Question 84: A patient has the following lab result: troponin I level of 2.5 ng/mL (normal less than 0.04 ng/mL). Combined with chest pain and ST elevation on ECG, this indicates:
Answer: B — Elevated troponin is the most specific biomarker for cardiac muscle damage. A troponin of 2.5 with chest pain and ST elevation confirms acute MI (STEMI). The patient needs emergent cardiac catheterization and reperfusion therapy.
Question 85: A nurse is assessing a newborn and notes yellow discoloration of the skin and sclera at 18 hours of life. This finding suggests:
Answer: C — Jaundice appearing within the first 24 hours of life is always considered pathological (not physiological, which appears after 24 hours). Causes include Rh or ABO blood type incompatibility and require immediate bilirubin level assessment, investigation, and likely phototherapy.

- SATA: Treat each option as True/False independently — don’t look for patterns
- Priority questions: Use ABC then Maslow. Acute > Chronic. Unstable > Stable.
- Delegation: RNs handle assessments & unstable patients. UAP handles routine tasks on stable patients.
- “First action” Qs: Always assess before intervening — unless immediate life threat exists
- NGN bowtie/matrix: Read all findings first, identify the most urgent concern, then select conditions & actions
- Eliminate clearly wrong answers first, then choose most therapeutic / least restrictive option
