A client is to receive a dose of fluphenazine hydrochloride (Prolixin) by intramuscular injection. What is the most important nursing intervention related to the injection?

The most important nursing intervention related to the injection of fluphenazine hydrochloride (Prolixin) is to monitor the client for signs of extrapyramidal side effects (EPS).

Here are the steps:

1. Prior to the injection, the nurse should explain the procedure to the client to alleviate any anxiety or fear.

2. The nurse should then prepare the medication, ensuring the correct dosage and checking the expiration date.

3. The nurse should select an appropriate site for the injection, typically the deltoid or gluteal muscle. The site should be clean and free of infection, inflammation, or lesions.

4. The nurse should then administer the injection using the correct technique. This includes inserting the needle at the correct angle, aspirating prior to injection to ensure the needle is not in a blood vessel, and injecting the medication slowly.

5. After the injection, the nurse should apply pressure to the site with a cotton ball or gauze to prevent bleeding.

6. The most important step is monitoring the client after the injection for signs of extrapyramidal side effects (EPS). These can include symptoms such as muscle stiffness, spasms, restlessness, tremors, and tardive dyskinesia (involuntary movements).

7. If any of these symptoms are observed, the nurse should report them to the healthcare provider immediately, as they may indicate a need to adjust the medication dosage or switch to a different medication.

8. The nurse should also provide education to the client and their family about the signs of EPS and the need to report them to the healthcare provider if they occur.

9. Finally, the nurse should document the medication administration and the client's response in the medical record.
