What is the appropriate action for administering multiple doses of epinephrine?

Administering multiple doses of epinephrine is crucial in the context of treating anaphylaxis or severe allergic reactions, where timely intervention can save a life. The correct practice is to administer doses at intervals of 5-15 minutes. This timing allows for a prompt response to the ongoing or recurring symptoms of anaphylaxis.

Epinephrine works quickly to counteract the life-threatening symptoms by constricting blood vessels, opening airways, and reducing swelling. However, its effects are not permanent, and symptoms can recur as the duration of the allergic reaction evolves. By allowing 5-15 minutes between doses, healthcare providers can monitor the patient's response and decide whether further doses are warranted while minimizing the risk of potential side effects from excessive dosing.

The other answer choices suggest either longer intervals or giving all doses at once, which could lead to inefficacy in managing the situation or increase the risk of adverse effects. Continuous monitoring and timely additional doses are critical in effectively managing anaphylaxis, hence the importance of the recommended 5-15 minute interval between doses.
