A nurse is reviewing the laboratory results of a client who has hypothyroidism. The client's calcium level is 7.6 mg/dL. When assessing the client, which of the following findings should the nurse expect?

Muscle twitching

Hypertension

Bounding pulse

Hypoactive bowel sounds

Answer and Explanation

The Correct Answer is A

A. Muscle twitching – Hypocalcemia (normal range: 8.5–10.5 mg/dL) causes neuromuscular excitability, leading to muscle twitching, tetany, and positive Chvostek's and Trousseau's signs.

B. Hypertension – Hypocalcemia does not cause hypertension; instead, it may lead to hypotension.

C. Bounding pulse – Hypocalcemia does not cause a bounding pulse; it may cause weak and irregular pulses.

D. Hypoactive bowel sounds – Hypocalcemia is more likely to cause hyperactive bowel sounds and diarrhea rather than hypoactive bowel sounds.
