A nurse is collecting data from a client who has a sodium level of 155 mEq/L (136-145 mEq/L). Which of the following manifestations should the nurse expect?

A. Hypernatremia causes fluid shifts out of cells, including neurons, leading to neurological manifestations such as confusion, lethargy, seizures, and decreased level of consciousness. B. Hypernatremia often causes fluid retention and increased vascular volume rather than hypotension; blood pressure may be normal or elevated depending on hydration status. C. Increased salivation is not associated with hypernatremia; in fact, dehydration from hypernatremia often leads to dry mucous membranes. D. Cool, clammy skin is typically seen in hypovolemic shock; in hypernatremia, skin may be dry due to cellular dehydration rather than moist and clammy.
