QUESTIONS AND DETAILED VERIFIED ANSWERS
FROM ACTUAL EXAMS TEST GRADE A+
1. A patient with heart failure is prescribed furosemide. Which finding requires
immediate intervention?
A. Potassium 3.1 mEq/L
B. Blood pressure 110/70 mmHg
C. Urine output 40 mL/hr
D. Mild ankle edema
Answer: A. Potassium 3.1 mEq/L
Rationale: Furosemide causes potassium loss; hypokalemia can lead to life-
threatening dysrhythmias.
2. Which sign is most indicative of hypoxia in an adult patient?
A. Bradycardia
B. Confusion
C. Hypertension
D. Fever
Answer: B. Confusion
Rationale: Early hypoxia often presents as restlessness or confusion due to
decreased cerebral oxygenation.
3. Priority action for a patient with chest pain?
,A. Obtain ECG
B. Give antacid
C. Encourage rest
D. Take full history
Answer: A. Obtain ECG
Rationale: ECG is essential to rule out myocardial infarction immediately.
4. Which electrolyte imbalance is associated with Trousseau’s sign?
A. Hyperkalemia
B. Hypocalcemia
C. Hypernatremia
D. Hypomagnesemia
Answer: B. Hypocalcemia
Rationale: Trousseau’s sign indicates low calcium levels.
5. First action for suspected anaphylaxis?
A. Give antihistamine
B. Administer epinephrine
C. Start oxygen
D. Insert IV line
Answer: B. Administer epinephrine
Rationale: Epinephrine is the first-line treatment for anaphylaxis.
6. Which lab value indicates kidney dysfunction?
A. Creatinine 0.8 mg/dL
B. BUN 28 mg/dL
C. Potassium 4.0 mEq/L
D. Sodium 140 mEq/L
,Answer: B. BUN 28 mg/dL
Rationale: Elevated BUN suggests impaired renal function.
7. Most common sign of left-sided heart failure?
A. Ascites
B. Pulmonary edema
C. Peripheral edema
D. Hepatomegaly
Answer: B. Pulmonary edema
Rationale: Left-sided HF leads to fluid accumulation in lungs.
8. Priority nursing intervention for stroke patient?
A. Oral fluids
B. Swallowing assessment
C. High-protein diet
D. Bed bath
Answer: B. Swallowing assessment
Rationale: Prevents aspiration before oral intake.
9. Which condition requires airborne precautions?
A. Influenza
B. Tuberculosis
C. MRSA
D. Hepatitis B
Answer: B. Tuberculosis
Rationale: TB spreads via airborne droplets.
, 10. Normal adult urine output per hour?
A. 10 mL/hr
B. 20 mL/hr
C. 30 mL/hr
D. 50 mL/hr
Answer: C. 30 mL/hr
Rationale: Minimum normal output is about 30 mL/hr.
11. Which symptom suggests hypoglycemia?
A. Fruity breath
B. Sweating and tremors
C. Deep breathing
D. Polyuria
Answer: B. Sweating and tremors
Rationale: Adrenergic response occurs in low glucose.
12. Priority in acute asthma attack?
A. Oral steroids
B. Oxygen therapy
C. Antibiotics
D. Chest X-ray
Answer: B. Oxygen therapy
Rationale: Restores oxygenation first.
13. Which is a classic sign of dehydration?
A. Bradycardia
B. Hypotension
