A nurse is reviewing the medical record of an adolescent and notes a low calcium level of 6.5 mEq/L. Which of the following findings should the nurse expect?

A. Diaphoretic skin is not a classic manifestation of hypocalcemia; it is more often associated with hyperthyroidism, fever, or sympathetic nervous system activation. B. Tachycardia may occur in some electrolyte imbalances, but it is not a hallmark sign of low calcium levels. C. Hypertension is not typically related to hypocalcemia; calcium deficiency more commonly affects neuromuscular excitability rather than blood pressure directly. D. A positive Chvostek’s sign (twitching of facial muscles when the cheek is tapped) is a classic indicator of hypocalcemia.
