Which of the following sites is assessed to check the pedal pulse?

Appeared in: AIIMS Rishikesh NO - 2019

Explanation

The term 'pedal' refers to the foot, making 'On the foot' the correct anatomical region.
The pedal pulse is specifically the dorsalis pedis pulse, which is palpated on the dorsal (top) surface of the foot.
As shown in the provided image, this pulse is located in the groove just lateral to the extensor tendon of the great toe.
This site is a key checkpoint for assessing arterial circulation to the distal part of the lower limb.

Option A: The site behind the knee is where the popliteal pulse is assessed, not the pedal pulse.
Option C: The area below the medial malleolus (the bony prominence on the inner ankle) is the site for the posterior tibial pulse.
Option D: The pulse assessed 'on the heart' is the apical pulse. It is auscultated with a stethoscope, not palpated like a peripheral pulse.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Anatomical locations for peripheral pulse assessment as background academic context rather than a clinical decision trigger.
Regular assessment of the pedal pulse is a critical nursing skill for evaluating perfusion in the lower extremities, especially in patients with diabetes, peripheral artery disease (PAD), or after vascular or orthopedic surgery on the leg.
A weak or absent pedal pulse can be one of the '5 Ps' of acute arterial occlusion (Pain, Pallor, Pulselessness, Paresthesia, Paralysis), signaling a medical emergency that requires immediate intervention to save the limb.
What if? If the dorsalis pedis pulse is not palpable (which can be a normal anatomical variation), the nurse's next step is to assess the posterior tibial pulse. If neither is found, a Doppler ultrasound should be used to confirm the presence or absence of blood flow.

How to Approach the Question

First, identify the key term in the question: 'pedal pulse'. The word 'pedal' is an anatomical term for the foot.
Scan the options to find the one that corresponds to this anatomical region. 'On the foot' is the most direct and correct choice.
Use your knowledge of anatomy to eliminate the other options. 'Behind the knee' is the popliteal pulse, 'below medial malleolus' is the posterior tibial pulse, and 'on the heart' refers to the apical pulse.
The provided image serves as a visual confirmation, showing the exact location of the dorsalis pedis (pedal) pulse on the top of the foot.
