A nurse is caring for a client who has been taking propranolol. Which of the following findings indicates a need to withhold the medication?

Blood pressure 156/90 mm Hg

Pulse 54/min

Potassium 5.2 mEq/L

Sodium 130 mEq/L

Answer and Explanation

The Correct Answer is B

A. While a blood pressure of 156/90 mm Hg may be elevated, it is not necessarily an indication to withhold propranolol, which is commonly used to treat hypertension.

B. A pulse rate of 54/min suggests bradycardia, which is a potential side effect of propranolol and may warrant withholding the medication.

C. A potassium level of 5.2 mEq/L is within the normal range (3.5-5.0 mEq/L) and is not typically a reason to withhold propranolol.

D. A sodium level of 130 mEq/L is within the normal range (135-145 mEq/L) and is not typically a reason to withhold propranolol.
