Chapter 1 How does the FDA ensure the safety and effectiveness of drugs? What types of drugs does the FDA regulate or control? - ANS-The FDA, through its Center for Drug Evaluation and Research (CDER), exercises control over whether prescription drugs and OTC drugs may be used for therapy. The mission of the CDER is to facilitate the availability of safe, effective drugs; keep unsafe or ineffective drugs off the market; improve the health of Americans; and provide clear, easily understandable drug information for safe and effective use. The FDA's Center for Biologics Evaluation and Research (CBER) regulates the use of biologics including serums, vaccines, and blood products. Chapter 2 Why are certain drugs placed in schedules? What does the nurse need to know when a scheduled drug is ordered? - ANS-Schedules refer to the potential for abuse. These schedules help the nurse identify the potential for abuse and require the nurse to maintain complete records for all quantities prescribed.

When educating the patient about a prescription, the nurse should also include this information on any prescription or refills as part of the education.
