Question

Trisha is learning how to do a first-aid procedure known as CPR. She is practicing using a mannequin, or a model of the top half of the human body. What is one limitation of a CPR mannequin? A. It is not possible to lay a CPR mannequin on the floor. B. It is not possible to check for a real pulse on a CPR mannequin. C. It is not possible to breathe into the mouth a CPR mannequin. D. It is not possible to press down on the chest of a CPR mannequin.

Answer 1

The correct option is B

Step-by-step explanation:

CPR means cardiopulmonary resuscitation. CPR is done as a first aid in emergency situations such as heart attack, rescued drowned patient and other situations that causes an individual's breathing or heartbeat to stop. CPR is done so the heart can resume it's function of supplying oxygenated blood to the body organs (especially the brain).

Checking the pulse is quite important while performing CPR because it's a direct measurement of the heart rate which can be used to know the effectiveness of the CPR or the progress made during the course of the CPR. Unfortunately, CPR mannequins are plastics/rubbers and hence cannot have real pulse.
