Correct answer: C — Sevoflurane

Sevoflurane is relatively non-pungent and suitable for inhalational induction. Phenylephrine is less appropriate because it would fit a different clinical clue or a separate anaesthetic problem. Desflurane is less appropriate because it would fit a different clinical clue or a separate anaesthetic problem. Glycopyrronium is less appropriate because it would fit a different clinical clue or a separate anaesthetic problem. Ketamine is less appropriate because it would fit a different clinical clue or a separate anaesthetic problem. In Primary FRCA pharmacology, link the clinical effect to the receptor, distribution or elimination mechanism rather than memorising isolated facts.
