Propofol induction dose (IV) is typically:

• A. 0.5-1 mg/kg
• B. 1.5-2.5 mg/kg
• C. 3-4 mg/kg
• D. 4-6 mg/kg

Answer: (B)

Propofol is used for rapid induction of anesthesia, so the dose is chosen to quickly produce loss of consciousness with a short, controllable effect. For a healthy adult, the standard IV induction dose is about 1.5 to 2.5 mg per kilogram of body weight, with many clinicians aiming around 2 mg/kg. This range typically achieves unconsciousness within about 30 seconds to a minute and allows prompt airway management. The lower end (around 0.5–1 mg/kg) tends to be insufficient for reliable induction and is more aligned with sedation rather than full induction. Doses in the higher range (3–4 mg/kg or more) increase the risk of profound hypotension and apnea and are not routine for standard induction, though they might be used in special circumstances with careful monitoring and titration. Patient factors such as age, cardiovascular status, and body composition can shift the ideal dose downward, but the 1.5–2.5 mg/kg window remains the typical starting target for most healthy adults.
