When administering mouth to mouth rescue breathing to an adult, you should breathe at the rate of how many breaths per minute?

Correct Answer: Option D — 12

Standard rescue breathing protocols for an adult require a rate of approximately 12 breaths per minute, or one breath every five seconds. This cadence ensures adequate oxygenation of the blood while preventing hyperventilation and gastric distension, which can lead to vomiting and aspiration during the resuscitation process.
