A 10-year-old patient is unresponsive in a park.

Comprehensive and Detailed Explanation (Based on NREMT standards):

For unresponsive children, NREMT guidelines recommend checking central pulses to determine circulation.

Option B (Carotid) is correct and is the preferred pulse site for children over 1 year old.

Option C (Femoral) is also acceptable as a central pulse, especially if the carotid pulse is difficult to locate.

Option A is a peripheral pulse and unreliable in shock.

Option D is used for infants under 1 year.

Option E is not used for pulse assessment.

Accurate pulse assessment guides CPR decisions and must be completed within 10 seconds.
