Certified Medical Assistant (CMA AAMA)Clinical Workflow and Patient IntakeEasy
A medical assistant is about to measure a patient's radial pulse. Which anatomical location should be used to palpate this pulse?
- AAnterior aspect of the elbow at the antecubital fossa
- BGroin, medial to the femoral head
- CMedial aspect of the wrist, thumb side
- DLateral aspect of the wrist, thumb side
Show answer & explanationAnswer & explanation
Correct answer: D. Lateral aspect of the wrist, thumb side
The radial pulse is palpated on the lateral (thumb) side of the anterior wrist, over the radial artery. The other locations correspond to different pulse points (brachial and femoral).
Why the other options are wrong
- A. This describes the brachial pulse location.
- B. This describes the femoral pulse location.
- C. Medial wrist is not where the radial artery runs.
Radial Pulse Location
The radial pulse is palpated at the lateral, thumb-side aspect of the anterior wrist over the radial artery.
- Most commonly used site for routine pulse checks
- Palpate with pads of fingers, not thumb
- Assess rate, rhythm, and volume
Memory trick: Radial = thumb side of wrist, like a ring on the thumb hand.
