A nurse is caring for a client who has hypocalcemia. Which of the following findings should the nurse expect?

Rationale A. Lethargy: Lethargy is more commonly associated with hypercalcemia, which depresses the central nervous system. In hypocalcemia, neuromuscular excitability is increased, so clients are more likely to experience irritability or paresthesia rather than lethargy. B. Constipation: Constipation is a manifestation of hypercalcemia due to decreased smooth muscle contractility. Hypocalcemia typically increases neuromuscular excitability and does not generally cause constipation. C. Positive Chvostek's sign: A positive Chvostek's sign indicates facial muscle twitching in response to tapping over the facial nerve and is a hallmark sign of hypocalcemia. It reflects increased neuromuscular excitability due to low calcium levels and is commonly used in assessment. D. Muscle flaccidity: Muscle flaccidity occurs with hypercalcemia or decreased neuromuscular activity. In hypocalcemia, muscles are more likely to exhibit tetany, spasms, or cramping due to heightened excitability, rather than flaccidity.
