A nurse is preparing to administer medications to a client. Which of the following resources should the nurse use to obtain information about medications they have never administered?

A. Food and Drug Administration (FDA): The FDA provides information about drug approval, safety, and labeling, but it is not the primary resource for practical administration guidance in a clinical setting. B. The Joint Commission (TJC): TJC focuses on healthcare quality and safety standards, accreditation, and patient safety goals, rather than detailed medication administration instructions. C. Medication Administration Record (MAR): The MAR contains the client-specific medication list, dosages, routes, and times. It is the most direct and reliable resource for a nurse to review prior to administering unfamiliar medications. D. Agency for Healthcare Research and Quality (AHRQ): AHRQ provides evidence-based guidelines and research on healthcare practices but does not serve as a primary source for step-by-step medication administration information.
