Answer: D - Needle-stick protection devices are required by law according to the Occupational Safety and Health Administration. These devices are engineering controls that reduce the risk of needle-sticks by providing a cover for used needles.

While all used needles should be placed directly into an approved sharps container, these engineering controls add an extra protective mechanism to avoid injury.
