The recommended location to assess a pulse in an unresponsive patient is indeed the carotid artery. This method is preferred primarily because the carotid artery is located centrally in the neck and is large enough to provide a detectable pulse even in situations where blood flow may be compromised.

In unresponsive patients, especially those who may not be breathing or exhibiting other vital signs, it is crucial to quickly assess circulation. The carotid pulse is accessible and can be easily palpated by placing two fingers in the groove between the trachea and the sternocleidomastoid muscle in the neck.

Additionally, other locations, such as the brachial, femoral, and radial arteries, while valid pulse-checking sites in various scenarios, may not be the most effective in assessing a pulse for an unresponsive individual. The brachial pulse is more commonly utilized in infants and can be less reliable in adults. The femoral artery is deep and requires more effort to locate, which may delay assessment. The radial artery is often too weak to palpate in cases of severe shock or cardiac arrest.

In summary, the carotid artery is the best choice for a quick and effective assessment of circulation in an unresponsive patient.
