4,100+ practice questions with rationales on iOS

Question 1

60 of 125. During postoperative day 2 for abdominal surgery, a patient receiving patient-controlled analgesia (PCA) with morphine reports sudden dyspnea. Assessment reveals tachypnea (28/min), absent breath sounds in left lower lobe, and SpO2 91% on 2L O2. Pain score is 4/10. Which action aligns best with clinical urgency?

  • A) A) Administer supplemental oxygen via non-rebreather mask
  • B) B) Increase PCA basal rate for better pain control
  • C) C) Auscultate lung fields systematically for changes
  • D) D) Encourage incentive spirometry to improve ventilation
Show rationale

Hypoxemia (SpO2 91% on O2) with tachypnea and absent breath signals acute respiratory compromise, possibly atelectasis or pneumonia. Immediate oxygen escalation addresses impaired gas exchange before further diagnostics. While spirometry (D) prevents complications, it doesn't correct current hypoxemia. Auscultation (C) is assessment, not intervention. Increasing opioids (B) would worsen respiratory depression. Per CMSRN protocols, unresolved hypoxia requires rapid correction to prevent respiratory failure.

Question 2

85 of 125. A nurse receives telephone handoff for a post-op colectomy patient with diabetes and heart failure. The outgoing nurse reports "blood pressure stable" but the receiving nurse notes 90/50 mmHg in the chart and absent urine output for 3 hours. Which response demonstrates critical analysis?

  • A) A) Clarify if the stable BP reading reflects the most recent measurement
  • B) B) Request immediate notification of the surgeon regarding hypotension
  • C) C) Verify whether IV fluid rates match the prescribed maintenance orders
  • D) D) Ask if orthostatic vital signs were assessed with position changes
Show rationale

The discordance between "stable" handoff terminology and documented hypotension (cue 1) coupled with oliguria (cue 2) in a patient with heart failure requires data verification first. Option B bypasses essential clarification of current status. Option C/D address complications but not the handoff accuracy gap. CMSRN standards emphasize validating discrepancies during handoff to prevent errors. Clarification ensures appropriate action based on accurate data, whereas other options assume the chart is correct without reconciling conflicting reports.

Question 3

111 of 125. When a nurse's suggested evidence-based protocol change is rejected by the unit council, they feel dismissed. Which reflection approach best supports professional resilience?

  • A) A) Re-examining the proposal for alignment with organizational priorities and resubmitting
  • B) B) Seeking mentorship on persuasive communication strategies from a senior educator
  • C) C) Documenting the incident in a professional development portfolio for annual review
  • D) D) Presenting the idea at a hospital-wide committee to bypass unit-level resistance
Show rationale

Critical reassessment of the proposal demonstrates adaptive self-regulation through constructive response to feedback. Option B focuses on communication skills rather than proposal quality. Option C documents without active improvement. Option D escalates prematurely without addressing committee feedback. AMSN standards emphasize using setbacks for reflective refinement of professional contributions.

Question 4

101 of 125. A diabetic patient with stage 3 CKD has a foot ulcer with purulent drainage. WBC is 14.5 x10³/μL, and creatinine is 2.8 mg/dL (up from baseline 1.9). Which antibiotic choice demonstrates safest clinical reasoning?

  • A) A) Starting vancomycin IV per sepsis protocol
  • B) B) Awaiting culture results before initiating therapy
  • C) C) Prescribing cephalexin orally for gram-positive coverage
  • D) D) Administering gentamicin IV for broad-spectrum coverage
Show rationale

Purulent drainage, elevated WBC, and acute kidney injury (rising creatinine) suggest systemic infection requiring urgent IV antibiotics. Vancomycin covers MRSA while allowing renal dosing adjustments. Delaying treatment (B) risks sepsis progression. Cephalexin (C) may lack MRSA coverage and requires renal clearance. Gentamicin (D) is nephrotoxic and contraindicated in renal impairment. CMSRN guidelines emphasize early, appropriate antibiotics in immunocompromised patients with systemic signs.

Question 5

121 of 125. A hard-of-hearing COPD patient on BiPAP struggles with communication. The nurse wants to explain the weaning process. The patient has intact cognition but cannot use hearing aids with the mask. Which strategy is most effective?

  • A) A) Write detailed instructions for the patient to read independently.
  • B) B) Use exaggerated lip movements while speaking slowly near the ear.
  • C) C) Demonstrate weaning steps visually using gestures and equipment.
  • D) D) Defer teaching until BiPAP is discontinued for easier communication.
Show rationale

Visual demonstration accommodates hearing limitations without relying on auditory input. Option A assumes literacy and ignores comprehension checks. Option B is ineffective with mask noise. Option D delays critical education. Cues (BiPAP, intact cognition) support kinesthetic learning per AMSN standards.

Question 6

14 of 125. When using SBAR to escalate care for a post-op patient with chest pain radiating to the jaw, which Situation statement ensures clarity?

  • A) A) History of hypertension and current morphine PCA usage
  • B) B) ST-elevation on ECG with troponin rise confirms myocardial infarction
  • C) C) New crushing substernal pain with diaphoresis and nausea
  • D) D) Recommend transferring to ICU and consulting cardiology stat
Show rationale

Situation (S) concisely states the acute problem. C describes symptom quality/associated signs without interpretation. A is Background. B is Assessment (interpretation). D is Recommendation. Radiation and autonomic symptoms are critical discriminators for cardiac pain; SBAR protocol mandates starting with objective observations before conclusions.

Question 7

116 of 125. Between patient rounds, a nurse plans to chart assessments but is interrupted by a colleague asking for help with a difficult IV start, a pharmacy call about a medication discrepancy, and a patient's call light for water. Which response balances efficiency and patient care?

  • A) A) Postpone charting to assist with the IV and call light first
  • B) B) Ask the colleague to wait, resolve the pharmacy query, then help
  • C) C) Delegate the call light response and address IV/pharmacy issues
  • D) D) Complete charting before responding to any interruptions
Show rationale

Medication discrepancies (pharmacy call) and IV access for treatment require RN expertise, while hydration needs can be delegated. Option A delays medication safety verification. Option B ignores immediate patient requests. Option D disregards team needs. Delegating simple tasks (water) to NAP allows focus on high-skill interventions. Addressing pharmacy concerns prevents errors per Joint Commission standards, and assisting with IV access supports workflow efficiency without compromising care continuity. Brief charting delays are acceptable for acute issues.

Question 8

8 of 125. A nurse prepares SBAR for a rapid response call for an oncology patient with neutropenic fever (39°C) and systolic BP drop from 130 to 85 mmHg in 30 minutes. Which Recommendation aligns with sepsis guidelines?

  • A) A) Suggest repeating vital signs in 15 minutes for trend confirmation
  • B) B) Request blood cultures, broad-spectrum antibiotics, and fluid bolus
  • C) C) Order a chest X-ray and urinary analysis for infection source
  • D) D) Initiate acetaminophen and monitor for fever reduction
Show rationale

B follows sepsis-bundle standards: cultures, antibiotics, and fluids for hypotension. A delays time-sensitive intervention. C omits antibiotics/fluids. D addresses fever but not perfusion. Neutropenia and rapid BP drop are discriminating cues for sepsis urgency; guidelines prioritize immediate antimicrobials/fluid resuscitation over diagnostic tests.

Question 9

7 of 125. A nurse is triaging phone calls. Caller 1: Patient's spouse reports the patient (history of DVT, discharged yesterday) has new calf swelling and tenderness. Caller 2: Patient reports incisional drainage 3 days post-op, no fever or pain increase. Caller 3: Patient with diabetes reports a fasting BG of 160 mg/dL this morning. Caller 4: Patient requests renewal of a blood pressure prescription refill due tomorrow. Which caller requires the nurse to advise seeking immediate emergency care?

  • A) A) The spouse reporting new calf swelling and tenderness post-DVT discharge.
  • B) B) The patient reporting incisional drainage without fever or increased pain.
  • C) C) The patient reporting a fasting blood glucose of 160 mg/dL.
  • D) D) The patient needing a blood pressure prescription refilled tomorrow.
Show rationale

New calf swelling and tenderness in a patient with a recent DVT history is a hallmark symptom of a potential new or recurrent DVT, which carries a high risk for pulmonary embolism (PE), a life-threatening emergency requiring immediate ED evaluation. Incisional drainage without systemic signs (B) needs assessment but isn't typically emergent. Elevated fasting BG (C) requires follow-up but isn't acutely dangerous. Medication refill (D) is administrative.

Question 10

10 of 125. A veteran with PTSD and chronic pain becomes hypervigilant during a crowded unit transfer, yelling at staff about "ambush tactics." His heart rate is 130 bpm, and he's blocking access to his IV site. Which response prioritizes therapeutic de-escalation?

  • A) A) Assign a male nurse to assertively redirect him to comply with care
  • B) B) Clear non-essential personnel and speak from his visual periphery
  • C) C) Administer prescribed PRN lorazepam to rapidly reduce anxiety
  • D) D) Remind him that staff are healthcare professionals, not military
Show rationale

Reducing perceived threats (crowds, direct confrontation) addresses PTSD triggers. Option A escalates via gender-specific coercion. Option C uses medication prematurely, contravening de-escalation-first protocols. Option D invalidates his reality, worsening distrust. Non-confrontational positioning and space creation align with trauma-informed care standards for hyperarousal states.

Question 11

34 of 125. A nurse is caring for four patients: 1) Post-op day 2 hip replacement reporting 7/10 pain, 2) New admission with uncontrolled type 2 diabetes and blood glucose of 320 mg/dL, 3) COPD exacerbation requiring nebulizer treatment now, and 4) Discharge teaching for CHF. The unit secretary notifies the nurse that a physician is waiting on callback for patient #2. Which action best demonstrates effective time management?

  • A) A) Complete discharge teaching first since it was previously scheduled
  • B) B) Administer the nebulizer treatment while returning the physician's call
  • C) C) Assess the hip replacement patient's pain before addressing other needs
  • D) D) Address the glucose result and physician callback immediately
Show rationale

Uncontrolled hyperglycemia (320 mg/dL) poses immediate risks like ketoacidosis, requiring prompt intervention per ADA guidelines. The physician callback directly relates to this acute issue. While pain management and scheduled treatments are important, the combination of a critical lab value and pending provider communication creates urgency. Option B attempts task clustering but risks incomplete attention to both tasks. Option A delays an unstable condition for routine care. Option C addresses discomfort but not the highest physiological risk. Addressing the glucose and callback first prevents complications and leverages the available provider contact.

Question 12

84 of 125. A patient with cirrhosis has an EWS score of 6 (HR 130, SBP 85, RR 24, mild agitation). Which collateral information most critically modifies EWS interpretation?

  • A) A) Hemoglobin of 8.2 g/dL from yesterday
  • B) B) Last INR result of 2.5 eight hours ago
  • C) C) Family report of 24-hour alcohol withdrawal symptoms
  • D) D) Documentation of non-adherence to diuretics
Show rationale

Agitation and tachycardia in cirrhosis with unreported alcohol withdrawal indicate delirium tremens risk, escalating the EWS score's severity. Option C provides context for neurological/vital sign changes, requiring benzodiazepines and ICU consideration. Option A explains anemia but doesn't acutely worsen EWS. Option B’s stable INR doesn't explain hemodynamic changes. Option D suggests fluid overload but lacks acute respiratory/neurological correlation. EWS accuracy relies on contextual data; withdrawal mandates immediate intervention beyond standard scoring.

Question 13

20 of 125. A patient with cirrhosis and hepatic encephalopathy exhibits asterixis and agitation. Vital signs are stable. The family reports the patient consumed deli meats yesterday. Which intervention is most critical?

  • A) A) Administering scheduled lactulose orally
  • B) B) Placing bilateral padded bed rails
  • C) C) Drawing ammonia levels immediately
  • D) D) Starting a low-protein diet today
Show rationale

Agitation with asterixis indicates worsening encephalopathy, posing high fall/injury risk, making safety measures (B) urgent per JC safety goals. Lactulose (A) reduces ammonia but isn't immediate for injury prevention. Ammonia levels (C) confirm diagnosis but don't mitigate acute risk. Diet change (D) is important but less pressing than environmental safety for a confused patient. Deli meat (high in sodium and protein) likely precipitated the episode.

Question 14

108 of 125. During a hospital fire alarm, a nurse discovers a visitor having a tonic-clonic seizure near an oxygen-dependent patient's room. Which action demonstrates effective crisis resource utilization?

  • A) A) Close all patient doors and activate the nearest fire pull station
  • B) B) Move the seizing visitor into the nearest vacant patient room
  • C) C) Retrieve the unit's seizure rescue kit and administer PRN lorazepam
  • D) D) Direct nearby staff to clear the corridor of equipment and furniture
Show rationale

Closing doors contains fire/smoke spread and activating alarms mobilizes specialized responders - critical in dual crises per hospital emergency protocols. Option B risks moving a seizing person unnecessarily and delays fire containment. Option C focuses only on the seizure while ignoring fire hazards near oxygen. Option D addresses injury prevention but neglects immediate fire response requirements. RACE protocol (Rescue, Alarm, Contain, Extinguish) prioritizes alarm activation and containment for imminent hazards.

Question 15

37 of 125. A 62-year-old patient with COPD and heart failure has an EWS score of 7 (RR 28/min, SpO₂ 89% on 2L NC, HR 112, systolic BP 90 mmHg). The nurse notes new confusion. Which action best aligns with EWS protocols?

  • A) A) Administer PRN supplemental oxygen and reassess in 30 minutes
  • B) B) Increase oxygen flow rate to 4L/min and document findings
  • C) C) Notify the rapid response team while preparing transfer equipment
  • D) D) Obtain a stat ECG and administer prescribed bronchodilators
Show rationale

An EWS score of 7 with new confusion indicates critical deterioration requiring immediate escalation per standard EWS protocols. Option C activates rapid response for advanced assessment/intervention, addressing hypoxia and neurological change. Option A delays escalation despite low SpO₂ and confusion. Option B addresses oxygenation but ignores systemic deterioration and neurological cues. Option D focuses on cardiac/pulmonary management but delays team notification for high-risk instability. EWS guidelines mandate urgent team activation for scores ≥7 with neurological decline.
