The nurse is giving an intramuscular (IM) injection. Upon aspiration, the nurse notices blood return in the syringe. What should the nurse do?
Give the injection and hold pressure over the site for 3 minutes.
Administer the injection at a slower rate.
Withdraw the needle and prepare the injection again.
Pull the needle back slightly and inject the medication.
The Correct Answer is C
A. Continuing with the injection after seeing blood return increases the risk of injecting into a blood vessel, which is not safe for IM injections.
B. Administering at a slower rate does not address the issue of possible intravascular injection.
C. If blood is aspirated, the correct procedure is to withdraw the needle, dispose of the medication, and prepare a new dose to prevent intravascular administration, as IM injections are meant to be given into muscle tissue, not into a vein.
D. Pulling the needle back slightly is not recommended because it does not ensure that the needle is completely out of the blood vessel.

C. The pulmonary artery carries deoxygenated blood from the heart to the lungs and is not involved in coronary circulation.
