How does a nurse assess the dorsalis pedis pulse?

Assessing the dorsalis pedis pulse involves palpating the pulse at a specific anatomical location, which is correctly described as placing the fingertips lateral to the extensor tendon of the big toe. This area corresponds to the location of the artery that runs along the dorsum of the foot, making it the optimal site for measuring the pulse.

To locate the dorsalis pedis pulse, a nurse typically positions their fingers on the upper surface of the foot, just adjacent to the tendon that can be felt when the big toe is extended. This technique allows for accurate detection of the pulse by feeling for the rhythm and strength of the blood flow through the artery.

In contrast to the correct method, using a stethoscope would not be effective for checking the dorsalis pedis pulse, as it is generally assessed by palpation rather than auscultation. Applying pressure with the palm of the hand would likely inhibit the ability to feel the pulsation accurately, as it does not target the artery. Lastly, directly observing the foot's color does not provide information about the pulse or blood flow. While changes in color can indicate issues with circulation, they do not provide the direct measurement of pulse that is necessary for a thorough vascular assessment.
