Which regulatory body oversees medical devices in the United States?

• A. The FDA (U.S. Food and Drug Administration)
• B. The EMA
• C. The WHO
• D. The NCI

Answer: (A)

In the United States, medical devices are regulated by the FDA. The Food and Drug Administration, through its Center for Devices and Radiological Health, ensures that devices marketed in the U.S. are safe and effective. It does this by classifying devices by risk, requiring premarket submissions (such as 510(k) for many devices or Premarket Approval for high-risk ones), and enforcing quality and labeling standards. After a device is on the market, the FDA continues to monitor safety through postmarket reporting and inspections to make sure manufacturers comply with good manufacturing practices.

Other organizations operate in different contexts: the EMA regulates devices in Europe, the WHO provides international health guidance but does not approve U.S. devices, and the NCI focuses on cancer research rather than regulatory approval.
