ADULT-GERONTOLOGY ACUTE CARE NURSE PRACTITIONER
(AGACNP) TEST BANK WITH
100 HIGH-YIELD PRACTICE QUESTIONS WITH DETAILED CLINICAL
RATIONALES FOR BOARD EXAM AND CRITICAL CARE SUCCESS
Question 1
A patient admitted with heart failure presents with worsening dyspnea, crackles, and bilateral
lower-extremity edema. Which pathophysiologic process is primarily responsible for these
findings?
A. Increased cardiac output
B. Fluid overload from decreased cardiac pumping ability
C. Hyperventilation syndrome
D. Peripheral vasodilation only
Correct Answer:
B. Fluid overload from decreased cardiac pumping ability
Rationale:
Heart failure occurs when the heart cannot pump effectively to meet metabolic demands.
Reduced cardiac output activates compensatory mechanisms such as the renin-angiotensin-
aldosterone system, leading to sodium and water retention.
This fluid accumulation causes:
• Pulmonary congestion producing crackles and dyspnea
• Peripheral edema
• Weight gain
• Reduced oxygenation
Prompt recognition is essential to prevent progression to respiratory failure.
Question 2
,A patient with septic shock remains hypotensive despite adequate fluid resuscitation. Which
medication is commonly initiated next?
A. Beta blockers
B. Vasopressors
C. Antihistamines
D. Diuretics
Correct Answer:
B. Vasopressors
Rationale:
Persistent hypotension after fluid replacement indicates severe circulatory failure requiring
vasopressor support.
Vasopressors:
• Increase vascular tone
• Improve blood pressure
• Maintain organ perfusion
Norepinephrine is commonly the first-line agent in septic shock management.
Question 3
A patient with COPD exacerbation develops increasing somnolence and confusion. Which
complication should the AGACNP suspect?
A. Hypercalcemia
B. Hypercapnic respiratory failure
C. Stable COPD recovery
D. Hypothyroidism
Correct Answer:
B. Hypercapnic respiratory failure
Rationale:
COPD exacerbations can impair ventilation causing carbon dioxide retention.
Elevated CO2 levels may produce:
, • Drowsiness
• Headache
• Confusion
• Respiratory acidosis
Untreated respiratory failure may progress to respiratory arrest.
Question 4
Which assessment finding most strongly suggests pulmonary embolism?
A. Sudden dyspnea and pleuritic chest pain
B. Polyuria
C. Gradual weight gain
D. Bradycardia
Correct Answer:
A. Sudden dyspnea and pleuritic chest pain
Rationale:
Pulmonary embolism commonly presents with:
• Sudden shortness of breath
• Sharp chest pain
• Tachycardia
• Hypoxemia
Large emboli may also cause hypotension and shock.
Question 5
A patient with acute kidney injury develops potassium level of 6.5 mEq/L. Why is this finding
dangerous?
A. Risk of cardiac dysrhythmias
B. Improved renal function
, C. Increased oxygenation
D. Stable electrolyte balance
Correct Answer:
A. Risk of cardiac dysrhythmias
Rationale:
Hyperkalemia alters cardiac electrical conduction and may lead to:
• Peaked T waves
• Ventricular dysrhythmias
• Cardiac arrest
Immediate treatment is required.
Question 6
A patient with stroke suddenly loses the gag reflex. What is the priority concern?
A. Aspiration risk
B. Hyperglycemia
C. Stable neurologic recovery
D. Hypertension only
Correct Answer:
A. Aspiration risk
Rationale:
Loss of protective airway reflexes increases risk for aspiration pneumonia.
Priority interventions include:
• Keeping the patient NPO
• Airway monitoring
• Swallow evaluation
