A common intravenous dose of naloxone for prompt reversal is

• A. 0.5-1 mcg/kg
• B. 10-20 mcg/kg
• C. 1-4 mcg/kg
• D. 0.04 mg

Answer: (C)

Naloxone works by competitively blocking mu-opioid receptors to rapidly reverse opioid-induced respiratory depression. Because the duration of different opioids can vary and the reversal effect may wear off, dosing is given in small, titratable boluses and repeated as needed to achieve adequate ventilation without overshooting into withdrawal or sudden cardiovascular stimulation. A common intravenous dose is 1–4 micrograms per kilogram, delivered as a bolus and repeated every few minutes if necessary until there is clear improvement in respiration and consciousness. This weight-based approach lets you quickly reverse the depressant effect while maintaining control over the level of reversal, reducing the risk of precipitating withdrawal or severe sympathetic effects. For example, a 70-kg patient would receive roughly 70–280 micrograms per bolus, adjusted based on response. Other options either underestimate the dose, risk excessive reversal, or aren’t aligned with the typical titratable, weight-based strategy that prioritizes rapid yet controlled recovery of ventilation.
