The nurse is preparing to administer a beta blocker to the client diagnosed with coronary artery disease. Which assessment data would cause the nurse to question administering the medication?
- A. The client has a BP of 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.
