When administering a subcutaneous injection,if blood appears in the syringe,you should:

A) pull the needle out opposite to the angle of entry
B) pull the needle out at the angle of entry
C) continue with the injection because it is normal this to occur
D) push the needle in further to move past the blood vessel

When administering a subcutaneous injection and blood appears in the syringe after aspiration, it indicates that the needle may have entered a blood vessel. The correct action is to withdraw the needle at the same angle it was inserted to minimize tissue damage and then attempt the injection at a different site. Continuing the injection could introduce medication into the bloodstream, which is not intended for a subcutaneous injection, and pushing the needle further could increase the risk of deeper tissue damage or intramuscular injection.
