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

A. Seizure: While seizures may occur in severe cases of hypernatremia, they are more typically associated with hyponatremia, where cerebral edema is more prominent due to water shifts into brain cells. B. Elevated hematocrit: An elevated hematocrit may be seen with dehydration, which can accompany hypernatremia, but it is not a direct or reliable indicator of sodium imbalance itself. C. Bradypnea: Respiratory changes like bradypnea are not characteristic of hypernatremia. This condition primarily affects the neurological system, not the respiratory system. D. Personality change: Hypernatremia causes cellular dehydration, particularly in brain cells, leading to neurological symptoms such as confusion, agitation, irritability, and personality changes.
