After administering an epinephrine auto-injector, what is the time frame within which you should reassess the patient?

  1. Immediately

  2. Three minutes

  3. Five minutes

  4. Ten minutes

The correct answer is: Five minutes

Reassessing the patient five minutes after administering an epinephrine auto-injector is crucial because this timeframe allows for a proper evaluation of the patient’s response to the medication. Epinephrine, particularly for conditions such as anaphylaxis, typically starts to have an effect within minutes of administration, but a complete assessment of efficacy, including any potential side effects or the need for additional doses, usually takes about five minutes. This period not only allows you to determine if the symptoms are improving or persisting, but also to monitor for any adverse effects that may arise from the medication itself. In emergency situations, immediate reassessment after administration may not provide an accurate picture of how the patient is responding, as symptoms may take some time to stabilize. Similarly, waiting longer than five minutes can result in a delayed response to ongoing symptoms or complications. Thus, the five-minute timeframe is considered optimal for both efficacy assessment and patient safety.
