Answer to Question 1

B
Patients with impaired renal function who are taking macrolide antibiotics will experience in-creased levels of rivaroxaban, increasing the risk of bleeding. It is correct to discuss using a dif-ferent antibiotic if possible. The nurse should not administer the dose without discussing the sit-uation with the provider. The patient's renal impairment is minor; if it were more severe, using a different anticoagulant might be appropriate. It is not correct to increase the dose of rivaroxaban.

Answer to Question 2

A
Both diphenhydramine and morphine sulfate act by depressing the central nervous system, lead-ing to sedation.
These drugs do not lead to toxicity unless given in excessive doses.
Sedation is an expected side effect of these medications, not an adverse reaction.
These drugs are not competitive antagonists, but they do act on the central nervous system.
