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?
Hypomagnesemia
Hypocalcemia
Hyponatremia
Hypokalemia
The Correct Answer is C
A. Hypomagnesemia: While lithium can affect magnesium levels, starting a new exercise program is not typically associated with hypomagnesemia. Hypomagnesemia may result in muscle weakness, tremors, and cardiac dysrhythmias.
B. Hypocalcemia: Starting a new exercise program is not typically associated with hypocalcemia. Hypocalcemia may present with muscle cramps, tetany, and seizures.
C. Hyponatremia: Starting a new exercise program may lead to dehydration and electrolyte imbalances, including hyponatremia (low sodium levels). This can have profound effects on patients taking lithium. Symptoms of hyponatremia include weakness, confusion, and seizures.
D. Hypokalemia is not a common occurrence among individuals doing exercise.

Correct Answer is ["500"]
Explanation
To calculate the dose of erythromycin per administration, you can follow these steps:
- Determine the total daily dose: 2 g.
- Divide the total daily dose by the number of equally divided doses per day: 2 g / 4 doses =
0.5 g per dose.
- Convert grams to milligrams: 0.5 g * 1000 mg/g = 500 mg.
So, the nurse should administer 500 mg of erythromycin per dose.
Correct Answer is B
Explanation
A. 0.45% sodium chloride: 0.45% sodium chloride solution, also known as half-normal saline, is a hypotonic solution used for rehydration and maintenance fluid therapy. However, in cases of
major burns where there is a significant loss of fluid and electrolytes, isotonic solutions are generally preferred.
B. Lactated Ringer's: Lactated Ringer's solution is an isotonic crystalloid solution that closely resembles the electrolyte composition of extracellular fluid. It is commonly used for fluid resuscitation in clients with major burns to replace lost fluids and electrolytes and restore
intravascular volume.
C. Dextrose 5% in water: Dextrose 5% in water is a hypotonic solution used primarily for hydration in clients with normal electrolyte levels or as a vehicle for administering medications.
It is not typically used for fluid resuscitation in clients with major burns, as it does not adequately replace lost electrolytes.
D. Dextrose 5% in 0.45% sodium chloride: This solution combines dextrose 5% and 0.45% sodium chloride and is used for maintenance fluid therapy and mild dehydration. However, in cases of major burns where there is significant fluid and electrolyte loss, isotonic solutions like lactated Ringer's or normal saline are preferred for fluid resuscitation.
