Before administering a calcium channel blocker to a client with hypertension, what parameter should the nurse check?

  • A. Serum calcium level
  • B. Apical pulse
  • C. Blood pressure
  • D. Respiratory rate
Correct Answer: C

Rationale: Before administering a calcium channel blocker to a client with hypertension, the nurse should check the client's blood pressure. Calcium channel blockers are prescribed to lower blood pressure, so it is essential to assess the current blood pressure to ensure safe administration and monitor the medication's effectiveness. Checking the serum calcium level (Choice A) is not necessary before administering a calcium channel blocker, as it does not directly impact the drug's action. Monitoring the apical pulse (Choice B) is important for other types of medications like beta-blockers, not specifically for calcium channel blockers. Assessing the respiratory rate (Choice D) is not directly related to administering calcium channel blockers for hypertension.
