1. A patient with chest pain is prescribed sublingual nitroglycerin. What is the
priority nursing action?
A. Administer with food
B. Assess blood pressure before administration
C. Give with water
D. Monitor blood glucose
Correct Answer: B
Rationale: Nitroglycerin causes vasodilation and can significantly lower blood pressure. Always
check BP before giving.
2. A patient with heart failure reports sudden weight gain of 3 pounds overnight.
What should the nurse do first?
A. Document and monitor
B. Notify the provider
C. Restrict fluids immediately
D. Encourage ambulation
Correct Answer: B
Rationale: Rapid weight gain indicates fluid retention and worsening heart failure.
3. Which lab value is most concerning in a patient taking furosemide?
A. Sodium 138 mEq/L
B. Potassium 2.9 mEq/L
,C. Chloride 100 mEq/L
D. Glucose 100 mg/dL
Correct Answer: B
Rationale: Furosemide causes potassium loss; 2.9 indicates hypokalemia (risk for
dysrhythmias).
4. A patient with COPD is receiving oxygen at 6 L/min via nasal cannula. What is
the priority concern?
A. Oxygen toxicity
B. Respiratory alkalosis
C. Suppression of hypoxic drive
D. Hyperglycemia
Correct Answer: C
Rationale: COPD patients rely on hypoxic drive; high O2 can suppress respirations.
5. Which ABG indicates respiratory acidosis?
A. pH 7.48, CO₂ 30
B. pH 7.32, CO₂ 50
C. pH 7.50, HCO₃ 30
D. pH 7.40, CO₂ 40
Correct Answer: B
Rationale: Low pH + high CO₂ = respiratory acidosis.
6. A patient with DKA will most likely exhibit:
A. Slow, shallow breathing
B. Kussmaul respirations
C. Bradypnea
D. Apnea
Correct Answer: B
Rationale: DKA causes metabolic acidosis; body compensates with deep, rapid breathing.
, 7. Which electrolyte imbalance causes peaked T waves?
A. Hypokalemia
B. Hyperkalemia
C. Hypocalcemia
D. Hyponatremia
Correct Answer: B
Rationale: Elevated potassium causes tall peaked T waves on ECG.
8. A patient receiving insulin becomes diaphoretic and confused. What is the first
action?
A. Check blood glucose
B. Give insulin
C. Call provider
D. Administer potassium
Correct Answer: A
Rationale: Symptoms suggest hypoglycemia; confirm glucose immediately.
9. Which finding indicates worsening left-sided heart failure?
A. Peripheral edema
B. Jugular vein distention
C. Crackles in lungs
D. Hepatomegaly
Correct Answer: C
Rationale: Left-sided failure causes pulmonary congestion.
10. A patient with MI reports chest pain unrelieved by nitroglycerin. What is the
priority?
A. Reassure patient
B. Administer morphine as ordered
C. Encourage coughing
D. Offer fluids
