A nurse is monitoring a client who was admitted for hypocalcemia. Which of the following findings should the nurse expect?

A. Positive Chvostek's sign. Hypocalcemia increases neuromuscular excitability, leading to involuntary twitching of facial muscles when the facial nerve is tapped. This sign is a well-known indicator of calcium deficiency and reflects heightened nerve sensitivity. B. Hypotension. While severe hypocalcemia can affect cardiovascular function, hypotension is not a primary or consistent finding. More commonly, calcium imbalances affect muscle contractions rather than directly causing low blood pressure. C. Confusion. Hypocalcemia can cause neurological symptoms, but confusion is more common in severe or prolonged cases. Early manifestations are usually neuromuscular, such as tetany or muscle cramps, rather than cognitive impairment. D. Positive Babinski reflex. This reflex is associated with upper motor neuron dysfunction and neurological disorders rather than electrolyte imbalances like hypocalcemia. Calcium deficiency primarily affects peripheral nerves and muscle excitability.
