Which of the following routes can a CMA administer medications?

The correct choice is based on the specific scope of practice for a Certified Medication Aide (CMA) in Iowa. CMAs are trained to administer medications using certain routes, and one of the primary methods is through transdermal patches and topical applications. These methods allow for medication to be absorbed through the skin, providing a non-invasive way to deliver treatment.

Transdermal patches offer a controlled release of medication over time, while topical applications deliver medication directly to a localized area. These methods are considered within the training and allowed practices for CMAs, differentiating them from more complex routes like intravenous (IV) or intramuscular (IM) injections.

Other options involve routes that often require more advanced training or licensure, such as IV and IM injections, which are typically beyond the scope of practice for a CMA. Hence, the choice that emphasizes transdermal and topical administration is the appropriate answer, reflecting the CMA's responsibility to safely provide care within their knowledge and training limitations.
