Final answer:
The appropriate way to dispose of a used syringe and needle is by placing it immediately into a puncture-resistant sharps disposal container and then following local regulations for disposal of the container once it is full.
Step-by-step explanation:
The appropriate way to dispose of a syringe and needle after giving an injection is to immediately place it in a specially designed sharps disposal container. These containers are typically made of puncture-resistant plastic with leak-resistant sides and a tight-fitting, puncture-resistant lid. This helps prevent needle-stick injuries and the spread of infections. It is crucial not to recap, bend, break, or hand manipulate used needles, for your safety as well as the safety of sanitation workers.
Once the sharps disposal container is full, it should be sealed and handled according to local regulations. Often, these can be brought to specific collection sites, such as pharmacies, healthcare providers, or fire stations. Some areas may offer special services for home pick-up or mail-back programs for these types of medical waste. It is important to stay informed about the regulations in your region.
