The nurse is caring for a client with hypertension who is prescribed a thiazide diuretic. The nurse should check which parameter before administering the medication?

  • A. Serum potassium level
  • B. Blood pressure
  • C. Heart rate
  • D. Serum sodium level
Correct Answer: B

Rationale: Before administering a thiazide diuretic to a client with hypertension, the nurse should check the blood pressure. Thiazide diuretics are prescribed to lower blood pressure, so assessing the client's blood pressure prior to administration helps to monitor the effectiveness of the medication and to ensure the client's safety. Checking the serum potassium level (Choice A), heart rate (Choice C), or serum sodium level (Choice D) are also important parameters in the care of a client on a thiazide diuretic, but the priority assessment before administering the medication is the blood pressure to evaluate the drug's effectiveness in managing hypertension.
