Question 1 of 5
A nurse is preparing to administer potassium chloride elixir 20 mEq/day PO to divide equally every 12 hr. Available is 6.7 mEq/5 mL. How many mL should the nurse administer per dose?
Correct Answer: A
Rationale:
Total dose is 20 mEq/day, so 10 mEq per dose every 12 hours. Calculation: (10 mEq / 6.7 mEq) x 5 mL = 7.46 mL, rounded to 7.5 mL per dose.
Question 2 of 5
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: D
Rationale: Exercise-induced sweating can lead to sodium loss, and lithium can further increase hyponatremia risk, requiring careful monitoring.
Question 3 of 5
A nurse is caring for a client who is taking triamterene. For which of the following laboratory values should the nurse withhold the medication?
Correct Answer: B
Rationale: Triamterene is a potassium-sparing diuretic, and a potassium level of 5.3 mEq/L (above normal) indicates hyperkalemia risk, so the medication should be withheld.

Correct Answer: A
Rationale: Pioglitazone, a thiazolidinedione, can cause fluid retention and edema, which requires monitoring, especially in clients with diabetes.
