A nurse is caring for a client who is taking lithium and reports starting a new exercise program. The nurse should assess the client for which of the following electrolyte imbalances?
Correct answer
C
Rationale
The correct answer is C: Hyponatremia. When a client taking lithium starts a new exercise program, they may sweat excessively, leading to increased sodium loss causing hyponatremia. Lithium can also interfere with the body's ability to regulate sodium levels. Hypomagnesemia (A), hypocalcemia (B), and hypokalemia (D) are not directly associated with lithium use or exercise. Sodium levels should be the priority assessment in this scenario.
