Explanation

The absence of a carotid pulse and respirations indicates cardiac arrest, a medical emergency requiring immediate intervention.
According to current Basic Life Support (BLS) guidelines from the American Heart Association (AHA), the sequence of actions is C-A-B: Compressions, Airway, and Breathing.
The first and most critical step is to initiate high-quality chest compressions on the lower sternum to circulate oxygenated blood to the brain and other vital organs.
This 'compressions-first' approach is crucial because any delay in restoring blood flow significantly reduces the chances of survival and good neurological outcome.

Option A: This is the 'A' (Airway) step in the C-A-B sequence. It is a critical part of resuscitation but is performed after starting the first cycle of 30 chest compressions, not as the initial action.
Option B: This is an outdated resuscitation guideline. Current BLS protocols recommend a ratio of 30 compressions to 2 rescue breaths for an adult. Furthermore, providing breaths (Breathing) is the third step in the C-A-B sequence.
Option D: This action is incorrect and wastes valuable time. The absence of a central pulse (carotid) is the definitive sign used to confirm cardiac arrest and start CPR.

Clinical Relevance

Nursing practice connection: Knowing Initial management of cardiac arrest (Basic Life Support - BLS) helps nurses interpret findings accurately and avoid errors in routine assessment, medication administration, and patient teaching.
Immediate initiation of high-quality CPR is the single most important determinant of survival and positive neurological outcomes following cardiac arrest.
Every nurse must be proficient in BLS, as they may be the first responder to a cardiac arrest in a hospital setting, and their prompt actions can save a life.
What if? If the patient was found to have a carotid pulse but was not breathing (i.e., respiratory arrest), the correct initial action would be to provide rescue breaths (1 breath every 6 seconds for an adult) and NOT start chest compressions.

How to Approach the Question

First, identify the clinical emergency presented in the stem: The patient has no carotid pulse and no respirations, which defines cardiac arrest.
Next, recall the standard algorithm for managing this emergency. The current guideline for Basic Life Support (BLS) is the C-A-B sequence (Compressions-Airway-Breathing).
Analyze the options in the context of the C-A-B sequence. The first priority is 'C' - Compressions.
Evaluate each option: 'Clears the airway' is 'A', 'Gives... inflations' is 'B', and 'Checks for radial pulse' is an incorrect assessment step.
Select the option that corresponds to initiating chest compressions. This is the correct first step in managing cardiac arrest.
