Correct Answer is B

Explanation

Choice A rationale:

Checking for a positive Chvostek’s sign is not relevant. This sign is associated with hypocalcemia, not with the lab values provided.

Choice B rationale:

The nurse should request a potassium replacement. The normal range for potassium is 3.5-5.0 mEq/L. A level of 3.0 mEq/L is low, indicating hypokalemia.

Choice C rationale:

Administering glucagon IM is not appropriate. The glucose level is within the normal range (70-110 mg/dL), so there is no need for glucagon.

Choice D rationale:

Discontinuing the TPN infusion is not the first action. The nurse should address the abnormal lab value (low potassium) first.

A. Decreased deep-tendon reflexes. B. Skeletal muscle weakness. C. Hypoactive bowel sounds. D. Tingling of the lips.

Correct Answer is D

Explanation

Choice A rationale:

Decreased deep-tendon reflexes are not a common symptom of hypocalcemia. Normal calcium levels in the blood range from 8.5 to 10.2 mg/dL1.

Choice B rationale:

Skeletal muscle weakness is a symptom of hypercalcemia, not hypocalcemia.

Choice C rationale:

Hypoactive bowel sounds are associated with hypercalcemia, not hypocalcemia.

Choice D rationale:

Tingling of the lips is a common symptom of hypocalcemia. This occurs due to increased excitability of the nerves.
