A nurse is caring for a patient post-thyroidectomy who reports tingling around the mouth and fingertips. Which electrolyte imbalance should the nurse suspect?

✓ Correct Answer: Option B

Tingling around the mouth and fingertips (paresthesia) is a classic sign of hypocalcemia, often due to accidental removal or damage to the parathyroid glands during thyroid surgery. These glands regulate calcium levels.
