Correct answer: D — Etomidate 0.3 mg/kg

Etomidate provides cardiovascular stability with minimal histamine release. Ketamine also provides haemodynamic stability and bronchodilation but with increased secretions and emergence phenomena. Propofol and thiopental at standard doses cause significant hypotension. Etomidate is preferred for haemodynamically compromised emergency patients.
