Q: In patients who go into cardiorespiratory arrest due to opioid overdose, the initial recommended dose of naloxone is?
A) .02 mg
B) .04 mg
C) .08 mg
D) 1 mg
E) 2 mg
Answer: E
Naloxone should be given in opioid toxicity depending on the clinical scenario. If a patient is spontaneously breathing, an initial dose of 0.04 mg intravenously (IV) is recommended. But if a patient is found to or near apnea, an initial dose of 1 mg can be tried to prevent impending respiratory failure and labor of ventilator. Patients in cardiorespiratory arrest due to opioid toxicity should receive an initial dose of a minimum of 2 mg.

ReplyDeleteIt's crucial to distinguish between spontaneous breathing and apnea when dosing. I didn’t realize the jump to 2mg was the standard for full arrest cases. This technical precision is exactly why formal naloxone administration training is vital for anyone responding to overdoses.
