Question

The nurse is preparing to administer a beta blocker to a client diagnosed with CAD. Which assessment data would cause the nurse to question administering the medication?

a. The client's BP is 110/70.
b. The client has an apical pulse of 56.
c. The client is complaining of a headache.
d. The client's potassium level is 4.5 mEq/L.

Answer 1

The nurse should question administering the beta blocker if the client has a low heart rate.

Step-by-step explanation:

The nurse should question administering the beta blocker to the client if the client has an apical pulse of 56 (b). Beta-blockers work by slowing down the heart rate, so if the client already has a low heart rate, administering a beta-blocker could further decrease the heart rate to a dangerously low level. Abrupt discontinuation of beta blockers can also cause rebound hypertension, so it's important for the nurse to assess the client's blood pressure (a) before administering the medication. Headache (c) is a known side effect of beta blockers but would not be a reason to question administering the medication. A potassium level of 4.5 mEq/L (d) is within the normal range and would not be a cause for concern in administering the medication.
