CAMRT Radiography Practice Exam

Which artery should be used to assess pulse when starting CPR?

1. Radial

2. Femoral

3. Carotid

4. Brachial

The correct answer is: Carotid

In an emergency situation where CPR is being initiated, accessing the carotid artery is the most appropriate choice for assessing a pulse. The carotid artery is located in the neck, making it relatively easy to palpate. It provides a strong pulse and is centrally located, which is crucial during a cardiac arrest scenario since it can be more reliable in detecting blood flow. During CPR, time is of the essence, and assessing the carotid pulse allows responders to quickly determine whether the heart is beating. If the pulse is not present, it reinforces the need to start chest compressions and rescue breaths immediately. While the radial and brachial arteries can also be used to assess pulse, they may not be as easily accessible or reliable in a critical emergency. The femoral artery, while it can be palpated, is less commonly used in assessing pulse in adults during CPR, particularly because the carotid artery is more directly indicative of central circulation. Therefore, using the carotid artery ensures a quicker and more efficient assessment of a patient’s condition.
