Questions & Verified Answers
1. Which clinical manifestation is most characteristic of hypocalcemia?
A. Muscle weakness and diminished deep tendon reflexes
B. Constipation and decreased bowel sounds
C. Polydipsia and polyuria
D. Positive Chvostek’s sign and Trousseau’s sign
Answer: D
Rationale: Hypocalcemia increases neuromuscular excitability. A positive Chvostek’s sign (facial twitching)
and Trousseau’s sign (carpal spasm) are classic indicators of low calcium levels. Applying this knowledge in
clinical settings supports safe, evidence-based practice and improves patient outcomes.
2. A patient is admitted with a potassium level of 6.2 mEq/L. Which ECG change should the
nurse expect?
A. Prominent U waves
B. Tall, peaked T waves
C. ST-segment depression
D. Shortened PR interval
Answer: B
Rationale: Hyperkalemia (potassium > 5.0 mEq/L) causes cardiac conduction disturbances, most notably tall,
peaked T waves and eventually QRS widening. Exam questions often test the ability to distinguish this concept
from closely related distractors, making a clear rationale essential for mastery. Applying this knowledge in
clinical settings supports safe, evidence-based practice and improves patient outcomes.
3. Interpret the following ABG: pH 7.30, PaCO2 52 mmHg, HCO3 24 mEq/L.
A. Metabolic Acidosis
B. Respiratory Alkalosis
C. Respiratory Acidosis
D. Metabolic Alkalosis
Answer: C
Rationale: The pH is low (< 7.35), indicating acidosis. The PaCO2 is high (> 45 mmHg), indicating a respiratory
cause. The bicarbonate is normal, suggesting no compensation yet. Exam questions often test the ability to
distinguish this concept from closely related distractors, making a clear rationale essential for mastery.

4. Which intervention is a priority for a post-operative patient to prevent atelectasis?
A. Administering prophylactic antibiotics
B. Encouraging use of the incentive spirometer every hour
C. Restricting fluid intake to decrease pulmonary secretions
D. Keeping the patient in a supine position
Answer: B
Rationale: Incentive spirometry promotes alveolar expansion and prevents the collapse of lung tissue
(atelectasis) in post-operative patients. Exam questions often test the ability to distinguish this concept from
closely related distractors, making a clear rationale essential for mastery. Applying this knowledge in clinical
settings supports safe, evidence-based practice and improves patient outcomes.
5. A patient with COPD is receiving oxygen therapy. Why is it important to avoid high-flow
oxygen?
A. High flow causes pulmonary edema
B. High flow causes rapid oxygen toxicity
C. It increases the risk of metabolic alkalosis
D. It may suppress the hypoxic drive to breathe
Answer: D
Rationale: Patients with chronic hypercapnia rely on low oxygen levels (hypoxic drive) to stimulate breathing.
Excess oxygen can reduce this drive, leading to respiratory arrest. This is an important clinical concept
because selecting the correct answer (D) requires understanding both the pathophysiology and the practical
nursing implications.
6. What is the primary goal of the ‘Time Out’ procedure in the operating room?
A. To ensure the surgeon is ready
B. To allow the anesthesia provider to check equipment
C. To confirm correct patient, site, and procedure
D. To document the start time of the surgery
Answer: C
Rationale: A ‘Time Out’ is a safety pause to verify the identity of the patient, the surgical site, and the
procedure being performed to prevent errors. Recognizing this principle allows the nurse to prioritize care,
anticipate complications, and provide accurate patient education. Exam questions often test the ability to
distinguish this concept from closely related distractors, making a clear rationale essential for mastery.
