A client is prescribed intravenous dopamine as part of treatment for shock. Which of the following medications should be available to the nurse when administering this medication?
1. Epinephrine (Adrenalin)
2. Naltrexone (Revia)
3. Phentolamine (Regitine)
4. Flumazenil (Romazicon)
3. Phentolamine (Regitine)
Rationale:
Extravasation of dopamine can cause severe, localized vasoconstriction resulting in tissue necrosis. The antidote for this is phentolamine (Regitine). Epinephrine (Adrenalin) is used for anaphylaxis. Naltrexone (Revia) is used for opiate overdose. Flumazenil (Romazicon) is used for benzodiazepine overdose.
