What is a potential consequence of using an incorrect injection site for IM injections?

Using an incorrect injection site for intramuscular (IM) injections can lead to tissue or nerve damage. IM injections are designed to be administered into specific muscle groups that have a good blood supply, allowing for optimal absorption of the medication. If the injection is not delivered into the correct muscle, it may inadvertently impact surrounding tissues, including nerves and blood vessels.

For instance, an injection into the deltoid muscle should be carefully placed in the middle third of the muscle to avoid the risk of damaging the radial nerve. Similarly, injecting into areas that have less muscle mass or are closer to major nerves can cause complications such as pain, numbness, or even permanent nerve damage. Proper technique and site selection are crucial to minimize these risks and ensure the safety and efficacy of the IM injection.

The other options do not correctly represent the primary concern with incorrect injection sites. Prolonged duration of action and improved absorption are not likely outcomes of using an improper site, and while improper dosage may occur due to other factors, it is not a direct consequence of site selection.
