After determining that an 8-year-old child is unresponsive, what is the best site to check for a pulse?

• A. Femoral artery
• B. Carotid artery
• C. Brachial artery
• D. Radial artery

Answer: (B)

Verified step by step guidance

1. Step 1: Understand the context of the problem. The question is asking about the best site to check for a pulse in an unresponsive 8-year-old child. This involves knowledge of anatomy and physiology, specifically the circulatory system and pulse points.
2. Step 2: Recall the major pulse points in the human body. Common pulse points include the carotid artery (neck), brachial artery (upper arm), radial artery (wrist), and femoral artery (groin). Each has specific uses depending on the situation and age of the individual.
3. Step 3: Consider the age of the child. For infants (under 1 year old), the brachial artery is typically used to check for a pulse. For children older than 1 year, the carotid artery is generally preferred because it is easier to locate and provides a strong pulse signal.
4. Step 4: Evaluate the accessibility of the pulse points in an emergency situation. The carotid artery is located in the neck and is often the most accessible and reliable site for checking a pulse in an unresponsive child over 1 year old.
5. Step 5: Conclude that the carotid artery is the best site to check for a pulse in an unresponsive 8-year-old child, based on anatomical location, ease of access, and reliability of the pulse signal.
