Answer:
Intramuscular injection (IM) technique
Step-by-step explanation:
The injection technique that has the highest risk of hematoma is the intramuscular injection (IM) technique. Hematoma is a condition where blood collects outside of the blood vessels and forms a localized swelling. This can occur when a needle punctures a blood vessel during the injection process and causes bleeding into the surrounding tissue.
Intramuscular injections are given into the muscle tissue and can cause hematoma if the needle accidentally punctures a blood vessel. Some factors that increase the risk of hematoma with an IM injection include using a large-gauge needle, injecting into a highly vascular area, using excessive force during the injection, or administering the injection to a patient with a bleeding disorder or who is taking blood-thinning medications.
