The health care professional has recommended sulfonamide therapy for a client. While obtaining the client's medical history, the nurse discovers that he is taking oral anticoagulants
Which of the following are the possible effects of combining sulfonamide therapy with oral anticoagulants?
A) Increased action of the anticoagulant
B) Increased risk of anaphylactic shock
C) Rendering of sulfonamide therapy ineffective
D) Development of leukopenia
Ans: A
Feedback:
Taking sulfonamide drugs when the client is already taking oral anticoagulants may result in increased action of the anticoagulants. Anaphylactic shock and leukopenia are some of the adverse reactions of sulfonamides but are not associated with mixing sulfonamides and anticoagulants. Oral anticoagulants do not decrease the effectiveness of sulfonamides.
