The client receiving naltrexone should be monitored for which of the following side effects?

• A. Nervousness
• B. Depressed respirations
• C. Hypotension
• D. Bradycardia

Answer: (A)

Naltrexone blocks opioid receptors, so in someone who is opioid-dependent it can precipitate withdrawal. The most likely and noticeable effect to monitor for is nervousness or agitation as an early withdrawal symptom. This occurs because the body is suddenly without the opioids it’s accustomed to, leading to autonomic and emotional signs such as anxiety and restlessness. Depressed respirations are not expected with naltrexone alone since it does not depress breathing; rather, respiratory depression is associated with opioid effects before blockade. Hypotension and bradycardia are not typical primary concerns with naltrexone either.
