Which of the following is a first priority assessment in CPR?

Appeared in: NORCET -4 , 2023

Explanation

The initial and highest priority action in any resuscitation scenario is to assess for consciousness or responsiveness.
This is performed by tapping the person's shoulder and shouting to see if they respond.
This step is crucial to determine if the person is truly unresponsive and requires emergency intervention, thus preventing unnecessary and potentially harmful CPR on a conscious individual.
The internationally recognized C-A-B (Compressions-Airway-Breathing) sequence of CPR begins only after unresponsiveness is confirmed.

Option A: Chest compressions are a critical intervention, but not the first assessment. They are initiated only after confirming the victim is unresponsive and has no pulse or normal breathing.
Option B: Checking for breathing is performed after determining the victim is unresponsive.
Option C: Managing the airway is part of the C-A-B sequence, which occurs after starting chest compressions.

Clinical Relevance

Nursing practice connection: Use the key finding related to Priority Assessment in Basic Life Support (BLS) to guide bedside assessment, documentation, and the next nursing action.
Always ensure scene safety before approaching a victim. A rescuer's safety is paramount and the first step before any patient interaction.
Checking for consciousness first prevents initiating CPR on a person who may be sleeping, intoxicated, or otherwise responsive but not in cardiac arrest, which could cause injury.
What if? If the person is conscious but appears to be choking and cannot speak or cough, the priority shifts from the CPR algorithm to performing abdominal thrusts (Heimlich maneuver).

How to Approach the Question

This is a priority-setting question, asking for the 'first' assessment in a specific clinical situation (CPR).
Recall the standard algorithm for Basic Life Support (BLS) as per AHA or other national guidelines.
The sequence always begins with ensuring scene safety, followed by checking the victim for a response (consciousness).
Evaluate each option against this established sequence. 'Check consciousness' is the first assessment performed on the victim.
The other options—chest compression, checking breathing, and checking airway—are all critical steps that occur later in the sequence, only after unresponsiveness has been confirmed.
