What is the maximum number of Epinephrine doses during cardiac arrest when using the 1:10,000 concentration?

• A. 3 doses of 1:10,000 every 5 minutes
• B. 1 mg every 3 minutes
• C. 5 mg every 5 minutes
• D. 2 mg every 5 minutes

Answer: (A)

During cardiac arrest, epinephrine at 1:10,000 is given as a 1 mg IV/IO dose and then repeated at intervals of about 3 to 5 minutes. In many practice guidelines and tests, there’s a practical cap on how many doses are given before reassessing the situation and continuing high-quality CPR. The best answer reflects giving three doses, each 1 mg, spaced roughly five minutes apart. This matches the standard dose per administration (1 mg) and the common teaching that up to three doses are given before moving on to reassessment or additional measures. The other options propose either higher single doses, different total amounts, or intervals that don’t align with the typical 1 mg per dose and the usual three-dose limit used in this context.
