A nurse is collecting data from a client who has a sodium level of 156 mEq/L. Which of the following findings should the nurse expect?

A. Nausea and vomiting: Nausea and vomiting can be present with hypernatremia (high sodium levels), but they are not the most prominent or specific symptom. The client may experience these symptoms, but they are usually accompanied by other signs. B. Altered mental status: This is a common manifestation of hypernatremia. The elevated sodium level causes an osmotic imbalance, leading to water shifting out of cells, which results in neurological symptoms, including confusion, lethargy, or seizures. C. Dysrhythmias: Dysrhythmias can occur with electrolyte imbalances, including hypernatremia, but the primary symptoms related to sodium levels are more often neurological in nature, such as confusion or altered mental status, rather than dysrhythmias specifically. D. Hypothermia: Hypernatremia typically causes an increase in body temperature, not hypothermia. Elevated sodium levels cause dehydration, which could contribute to increased body temperature rather than cooling.
