During an intramuscular injection, the patient asks why you pulled back on the syringe. What is the best nurse response?

• A. Because that is how we were taught to perform injections.
• B. Because best practice guidelines state the nurse should aspirate before injecting.
• C. Because I want to make sure the plunger slides smoothly in the syringe.
• D. Because I need to ensure the needle has not hit a blood vessel.

Answer: (D)

The main idea is safety: aspirating helps you verify the needle isn’t in a blood vessel before delivering the medication. When you pull back on the plunger, you’re looking for blood return in the syringe. If blood shows up, that signals intravascular placement, and injecting at that site could send the medication directly into the bloodstream, which may cause unintended systemic effects or tissue damage. If no blood appears, you can proceed, delivering the medication into the muscle where it’s intended to be absorbed gradually. This step is about preventing inadvertent intravascular injection and protecting the patient.
