In the NEALSIVMAN mapping, which drug is designated by the letter S?

• A. Succinylcholine
• B. Lidocaine
• C. Versed
• D. Fentanyl

Answer: (A)

The key idea here is that the S element in this mnemonic is linked to a rapid-acting depolarizing neuromuscular blocker. Succinylcholine provides the fastest onset of muscle paralysis, which is why it’s matched with that designation and is typically used for rapid sequence induction. The other drugs listed belong to different classes: lidocaine is a local anesthetic, Versed (midazolam) is a benzodiazepine for sedation, and fentanyl is an opioid analgesic. Because succinylcholine uniquely offers very quick, short-duration paralysis, it is the best fit for the S designation.
