How should a laboratory assistant dispose of a needle after a venipuncture?

The proper disposal of needles after a venipuncture is crucial for ensuring safety and preventing needle-stick injuries. Placing the uncapped needle and plastic holder in a rigid biohazard container is the correct procedure because these containers are specifically designed to safely contain sharp objects such as needles and ensure that they do not pose a risk to healthcare workers or the general public.

These biohazard containers are puncture-resistant and are used exclusively for disposal of sharps to minimize the risk of exposure to bloodborne pathogens. It also helps in the proper handling and disposal of hazardous waste, complying with health regulations and protocols.

The other methods mentioned pose risks to safety. Recapping the needle increases the likelihood of accidental needle-stick injuries, while wrapping the uncapped needle or discarding it in a regular garbage can does not provide adequate protection or compliance with biohazard waste disposal regulations. Proper training emphasizes the need for immediate disposal in a designated biohazard container, making this procedure essential for workplace safety.
