Answer to Question 1

Ans: A
Feedback:
The nurse should observe for decreased effectiveness of the antipsychotic drug in the client as the effect of the interaction of the antispasmodic drug and haloperidol. Increased risk for bleeding results from the interaction of oral anticoagulants with anti-infective drugs. Increased effect of the antispasmodic drug occurs with the interaction of an antispasmodic drug with a tricyclic antidepressant. Plasma concentrations are lowered due to the interaction of fosfomycin, which is an anti-infective, with metoclopramide, which is used to relieve gastric upset.

Answer to Question 2

Ans: B, D
Feedback:
Finasteride (Proscar) and dutasteride (Avodart) inhibit the conversion of testosterone into 5-alpha-dihydrotestosterone (DHT), which results in a decrease in prostate gland size, making them useful in the treatment of benign prostatic hypertrophy.
