Can you change injection site and use the same syringe if you aspirate blood?

If you aspirate blood while using a syringe, it typically indicates that the needle has entered a blood vessel. In such cases, it's best to withdraw the needle, discard the syringe, and use a new one for a different injection site. Reusing the same syringe after aspirating blood poses a risk of contamination and infection. Always prioritize safety and proper protocols when administering injections.
