The nurse is obtaining a medication history of a 48-year-old patient with an ear infection who is to receive penicillin therapy. The patient reports taking a beta-adrenergic blocker for his hypertension
The nurse would identify that this patient is at increased risk for which of the following if penicillin is administered?
A) Anaphylactic shock
B) Higher blood pressure
C) Excess bleeding
D) Heart attack
Ans: A
Feedback:
Combining penicillins with beta-adrenergic blocking drugs increases the risk of anaphylactic shock. Beta-adrenergic blocking drugs are used to control blood pressure and heart problems, but combining them with penicillins does not increase the risk of high blood pressure or heart attack. Risk of bleeding is maximized if penicillins are combined with anticoagulants.
