Grade A - WCU
1. A patient is admitted with a serum sodium level of 125 mEq/L. Which nursing
intervention is the highest priority?
A. Encouraging increased fluid intake
B. Administering a diuretic as ordered
C. Implementing seizure precautions
D. Providing a high-salt diet
Answer: C
Rationale: Hyponatremia (sodium < 135 mEq/L) can lead to cerebral edema and seizures.
Safety through seizure precautions is the priority.
2. Which of the following is a classic clinical manifestation of hypocalcemia?
A. Positive Trousseau’s sign
B. Constipation
C. Depressed deep tendon reflexes
D. Polyuria
Answer: A
Rationale: Hypocalcemia increases neuromuscular excitability, leading to signs like
Trousseau’s (carpal spasm) and Chvostek’s signs.

ECG change should the nurse monitor for?
A. Presence of U waves
B. Tall, peaked T waves
C. Widened QRS complex
D. Shortened ST segment
Answer: A
Rationale: Hypokalemia often results in the presence of U waves, ST-segment depression,
and flat or inverted T waves.
4. Which fluid is classified as a hypotonic solution?
A. 0.9% Normal Saline
B. Lactated Ringer’s
C. 0.45% Sodium Chloride
D. 5% Dextrose in 0.9% Saline

How does the nurse interpret these results?
A. Metabolic Acidosis
B. Respiratory Acidosis
C. Metabolic Alkalosis
D. Respiratory Alkalosis
Answer: B
Rationale: The pH is low (<7.35) and the PaCO2 is high (>45), indicating respiratory
acidosis.

action?
A. Perform a bladder scan
