Name 4 common points for checking pulse.

• A. Carotid, Temporal, Femoral, Brachial
• B. Radial, Ulnar, Posterior Tibial, Popliteal
• C. Carotid, Dorsalis Pedis, Radial, Femoral
• D. Carotid, Axillary, Scapular, Facial

Answer: (C)

Checking a pulse at multiple accessible sites lets you quickly gauge circulation to the heart and limbs. The four most commonly used points are the carotid pulse in the neck, the radial pulse at the wrist, the femoral pulse in the groin, and the dorsalis pedis pulse on the top of the foot. These sites are easy to reach on a person who is lying down or seated and provide reliable points to assess heart rate and rhythm.

The carotid pulse is often checked first in an unresponsive patient or when you need to know if blood is reaching the brain; it’s a strong central pulse, but you should only palpate one side at a time to avoid reducing blood flow to the brain. The radial pulse is the most convenient for a conscious person and is the typical site for routine heart rate assessment. The femoral pulse is large and accessible when peripheral perfusion is poor or the upper limbs aren’t reliable, giving a sense of central circulation to the legs and pelvis. The dorsalis pedis pulse checks distal circulation to the feet, helping assess overall limb perfusion.

Other pulses exist, such as temporal or brachial in certain contexts, but they’re not as commonly used for quick four-point assessment in basic first aid.
