Who among the following healthcare professionals is authorized to administer IV medication?

Nurses are the healthcare professionals authorized to administer intravenous (IV) medication. This responsibility requires specialized training and knowledge of pharmacology, patient assessment, and the management of IV therapy. Nurses are trained to ensure that medications are delivered safely and effectively, managing any complications that may arise during the administration.

The other options represent professions that do not typically have the authority or training to perform IV medication administration as part of their standard practice. Medical assistants have a supportive role in healthcare and usually do not have the scope of practice or training required to administer IV medications. Pharmacists focus on the preparation and dispensing of medications, providing guidance on drug interactions and side effects but are not involved in direct patient care that includes administering IVs. Physical therapists specialize in rehabilitation and therapeutic exercise, without direct training in medication administration. Thus, the role of administering IV medication is specifically designated to nurses who possess the necessary skills and certification for this critical task.
