1. A patient with heart failure has crackles, JVD, and weight gain. Which
order should the nurse question?
A. IV furosemide
B. Daily weights
C. Encourage oral fluids
D. Monitor potassium
Correct Answer: C
Rationale:
Heart failure involves fluid overload. Encouraging oral fluids worsens
pulmonary congestion. Diuretics, weights, and potassium monitoring are
appropriate.
2. A COPD patient is receiving oxygen at 6 L/min via nasal cannula.
Which finding requires intervention?
A. RR 18
B. O₂ sat 88%
C. Drowsiness
D. Barrel chest
Correct Answer: C
,Rationale:
High oxygen flow in COPD can suppress the hypoxic drive, leading to CO₂
retention and decreased LOC. An O₂ sat of ~88–92% is often acceptable
in COPD.
3. The priority assessment for a patient with suspected pulmonary
embolism is:
A. Lung sounds
B. Blood pressure
C. Oxygen saturation
D. Temperature
Correct Answer: C
Rationale:
PE causes impaired oxygenation. Airway and breathing come before
circulation (ABCs).
4. Which lab value is most important to monitor in a patient on heparin
infusion?
A. INR
B. aPTT
C. Platelets only
D. Hemoglobin
Correct Answer: B
Rationale:
aPTT measures heparin effectiveness. INR is for warfarin.
5. A patient on warfarin has an INR of 5.2. What is the nurse’s priority?
A. Give next dose
B. Encourage vitamin K foods
,C. Hold warfarin and notify provider
D. Recheck in 1 week
Correct Answer: C
Rationale:
An INR >4 increases bleeding risk. The medication must be held and the
provider notified immediately.
6. A patient with acute kidney injury has potassium 6.1 mEq/L. What is
the priority action?
A. Encourage fluids
B. Administer calcium gluconate
C. Place on telemetry
D. Restrict protein
Correct Answer: C
Rationale:
Hyperkalemia causes life-threatening arrhythmias. Continuous cardiac
monitoring is the immediate priority.
7. Which finding indicates digoxin toxicity?
A. Bradycardia
B. Green-yellow halos
C. Hypokalemia
D. All of the above
Correct Answer: D
, Rationale:
Classic digoxin toxicity signs include visual changes, bradycardia, and
low potassium, which increases toxicity risk.
8. A post-op patient suddenly develops stridor. What is the priority
action?
A. Assess incision
B. Call respiratory therapy
C. Prepare for intubation
D. Encourage coughing
Correct Answer: C
Rationale:
Stridor = airway obstruction. Airway emergencies require immediate
preparation for advanced airway management.
9. Which patient is at highest risk for pressure injuries?
A. BMI 32
B. Incontinent and immobile
C. Controlled diabetes
D. Ambulatory elderly
Correct Answer: B
Rationale:
Moisture, immobility, and poor perfusion are major risk factors for skin
breakdown.
