Correct Answer is D

Explanation

The intravenous route provides the most rapid onset of medication action because the medication is delivered directly into the bloodstream. However, this route also poses the greatest risk of adverse eﬀects if the medication is administered incorrectly or too rapidly because there is no opportunity for the body to metabolize or excrete the medication before it reaches its target organs.

A. The client’s family will also need to take medications to prevent infection. B. A typical course of treatment involves 6 to 9 months of consistent medication use. C.
