A nurse is planning to teach a group of newly licensed nurses about hypercalcemia. Which of the following manifestations should the nurse Include in the teaching?

Rationale: A. Stridor: Stridor is a high-pitched airway sound typically associated with hypocalcemia due to laryngeal spasms from increased neuromuscular excitability. It is not a common feature of hypercalcemia, where muscle excitability is decreased. B. Seizure: Seizures result from heightened neuronal activity, which occurs more frequently in hypocalcemia. Hypercalcemia depresses neural and muscular activity, making seizures an unlikely symptom. C. Elevated hematocrit: Elevated hematocrit can occur with dehydration but is not a direct effect of high serum calcium levels. It is not considered a hallmark manifestation of hypercalcemia. D. Personality change: Hypercalcemia affects the central nervous system, often leading to confusion, lethargy, or personality changes. These alterations occur due to the depressive effects of excess calcium on brain function.
