Which of the following sites needs to be assessed for a pulse during cardiac arrest in an adult?

Appeared in: SGPGI Nursing Officer-2024

Explanation

The carotid artery is the standard site for pulse assessment in an unresponsive adult as per Basic Life Support (BLS) guidelines.
It is a large, central artery located close to the heart, making it one of the last pulses to disappear when cardiac output is critically low.
Its location in the neck makes it quickly and easily accessible without removing extensive clothing, minimizing delays in starting CPR.

Option A: The femoral artery is a central pulse, but it is not the primary site for an initial pulse check in an adult cardiac arrest. It can be difficult to access quickly, especially if the patient is clothed.
Option C: The brachial artery is not the recommended site for assessing a pulse in an adult during cardiac arrest.
Option D: The apical pulse is not a palpable pulse. It is the sound of the heart contracting, which must be auscultated with a stethoscope.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Emergency Pulse Assessment in Adults as background academic context rather than a clinical decision trigger.
In a cardiac arrest scenario, time is critical. The pulse check should take no longer than 10 seconds. If a pulse is not definitively felt within this time, healthcare providers must assume pulselessness and begin chest compressions immediately to maximize the chances of survival.
What if the patient was an infant? The correct answer would change to the brachial artery. The brachial pulse is easier to palpate in infants due to their short, chubby necks.
Never check both carotid arteries simultaneously, as this can occlude blood flow to the brain and cause a syncopal episode or stroke.

How to Approach the Question

First, identify the key components of the question: the patient's age ('adult') and the clinical situation ('cardiac arrest').
Recall the standard Basic Life Support (BLS) guidelines for this specific scenario.
Consider the anatomical locations of the arteries listed in the options.
Evaluate each option based on its accessibility, reliability in a low-flow state (like cardiac arrest), and the established emergency protocols.
Eliminate options that are used for different age groups (Brachial for infants) or different assessment types (Apical for auscultation).
Select the option that represents the primary, most reliable, and quickest method for an adult in cardiac arrest, which is the carotid artery.
