Why should IV push opioids be administered slowly?

• A. To minimize adverse effects such as nausea, itching, and flushing
• B. To hasten relief
• C. To cause tachycardia
• D. To reduce analgesia duration

Answer: (A)

Administering IV opioids slowly reduces the rapid spike in drug levels in the bloodstream, which lowers the chance of side effects driven by that sudden peak. Opioids can cause histamine release, leading to flushing and itching, and a quick IV push can intensify these reactions as well as nausea and dizziness. By delivering the medication over a longer period, you still achieve pain relief while minimizing these adverse effects. It also helps lessen the risk of respiratory depression compared with a very rapid bolus. In practice, if more analgesia is needed, small additional doses can be given and titrated carefully.
