1. A patient with a history of heart failure presents with a sudden onset of shortness of
breath and pink, frothy sputum. Which rhythm is most commonly associated with the
development of acute pulmonary edema in this context?
A. Sinus Bradycardia
B. Premature Atrial Contractions
C. First-degree AV block
D. Atrial Fibrillation with Rapid Ventricular Response
Answer: D
Rationale: Atrial fibrillation with RVR decreases diastolic filling time and cardiac output,
leading to increased pulmonary hydrostatic pressure and acute pulmonary edema.
2. The nurse notes a high-pressure alarm on the mechanical ventilator of a patient with ARDS.
After assessing the patient, which action should the nurse take first?
A. Check for kinks in the ventilator tubing
B. Increase the oxygen concentration to 100%
C. Auscultate the patient’s breath sounds
D. Suction the endotracheal tube
, Answer: C
Rationale: The first step is always patient assessment. Auscultating breath sounds helps
determine if the cause is a pneumothorax, displacement of the tube, or obstruction.
3. A patient is admitted with Acute Kidney Injury (AKI) and a serum potassium level of 6.8
mEq/L. Which EKG change is the nurse most likely to observe?
A. Prominent U waves
B. ST-segment depression
C. Prolonged QT interval
D. Tall, peaked T waves
Answer: D
Rationale: Hyperkalemia (K+ > 5.0) typically manifests on an EKG as tall, peaked T waves,
followed by widening of the QRS complex as levels increase.
4. Which clinical manifestation would be expected in a patient experiencing the
compensatory stage of shock?
A. Metabolic acidosis
B. Anuria
C. Listlessness and lethargy
D. Narrowing pulse pressure
Answer: D
