Due to the risk of hitting the sciatic nerve, the least favored site for IM injection is which of the following?

A. Ask the client to state his name and medical record number: Asking the client to state identifiers is appropriate; however, relying solely on verbal confirmation without cross-checking with the armband and source document does not meet full identification standards. Patients may be confused, sedated, or provide incorrect information unintentionally.

B. Check the sign above the bed to the MAR & check the armband: The sign above the bed should never be used as a primary identifier because room assignments can change. While checking the armband is essential, including the bed sign introduces risk and does not align with best-practice identification policies.

C. Compare the source document to the client's armband & ask him to state his name: Best practice requires using at least two identifiers, such as full name and medical record number, and verifying them against the armband and the MAR. Asking the client to state their name rather than confirming it ensures active participation and reduces identification errors.

D. Call the client by name on MAR and observe his response: Calling the client by name and observing a response is insufficient because patients may respond reflexively even if misidentified. This method does not fulfill the requirement of using two independent identifiers to ensure safe medication administration.

A. The ventrogluteal: The ventrogluteal site is considered the safest for IM injections because it is free of major nerves and blood vessels. Even in thin patients, it provides adequate muscle mass and reduces the risk of nerve injury, making it a preferred site for medications like morphine.

B. The dorsalgluteal: The dorsalgluteal site is located near the sciatic nerve, which increases the risk of nerve injury, especially in extremely thin or cachectic patients like Mrs. Westmore. Due to her significant muscle and fat loss, the likelihood of accidentally hitting the nerve is higher, making this the least favored site for IM injections.

C. The vastus lateralis: The vastus lateralis (anterolateral thigh) is safe for IM injections, particularly in adults who may have reduced gluteal mass. It is free of major nerves and vessels, making it a suitable alternative when the gluteal muscles are atrophied.

D. The deltoid: The deltoid muscle is an option for small-volume IM injections, but in cachectic patients, muscle mass may be insufficient for larger doses. However, it is still safer than the dorsalgluteal site because it avoids proximity to the sciatic nerve.
