Final answer:
If you notice incomplete chest recoil during chest compressions in CPR, you should inform the person about its importance.
Step-by-step explanation:
If you notice that the person giving chest compressions is not allowing for complete chest recoil during a resuscitation attempt, your next course of action would be to inform the person about the importance of complete chest recoil. Complete chest recoil is vital in CPR as it allows blood to flow back into the heart and helps improve the effectiveness of compressions. By informing the person, you can ensure they understand the importance of this step and can adjust their technique accordingly.
