Which of the following is NOT listed as a sedation option for synchronized cardioversion?

• A. Etomidate
• B. Diazepam
• C. Morphine Sulfate
• D. Midazolam

Answer: (C)

Procedural sedation for synchronized cardioversion relies on agents that quickly sedate the patient while preserving airway control and stable blood pressure. Etomidate is valued for its rapid onset and minimal cardiovascular impact. Benzodiazepines like midazolam and diazepam provide sedation, anxiolysis, and amnesia, which helps the patient tolerate the shock without combative movement. Morphine sulfate, in contrast, is an opioid analgesic. It does not provide the rapid, controlled sedation needed for cardioversion and can depress respiration and lower blood pressure, complicating the procedure. Since the question asks which is not used for sedation in this setting, morphine sulfate is the one that does not fit.
