Which analgesic is listed with a maximum dose of 10 mg for synchronized cardioversion analgesia?

• A. Morphine Sulfate
• B. Fentanyl
• C. Hydromorphone
• D. Ketamine

Answer: (A)

Analgesia during synchronized cardioversion is guided by per-dose maximums in the protocol to balance pain relief with safety. The analgesic that has a defined maximum amount per administration in this context is morphine sulfate. This reflects its dosing is given in milligrams per dose and capped to reduce the risk of respiratory depression and hemodynamic instability during the procedure. The other options are dosed differently: fentanyl is given in micrograms per dose and typically doesn’t align with a fixed milligram ceiling; hydromorphone is usually limited by a smaller per-dose amount; ketamine is used for analgesia or sedation with dosing patterns not described as a simple fixed per-dose maximum in this setting. So morphine sulfate is the one associated with a defined maximum per administration for synchronized cardioversion analgesia.
