Final answer:
A hospital may only sell prescription drugs that are approved by the FDA.
Step-by-step explanation:
A hospital may not sell, purchase, or trade prescription drugs unless certain criteria are met. One of the key criteria is that the drugs must be approved by the Food and Drug Administration (FDA) for sale in the United States. The FDA regulates the safety and efficacy of medicines to protect the public from potential harm. This means that a hospital can only sell prescription drugs that have gone through rigorous testing and have been deemed safe and effective.
