North Carolina EMT State Practice Exam

Where is the popliteal pulse located?

1. Behind the ankle

2. On top of the foot

3. Behind the knee

4. On the wrist

The correct answer is: Behind the knee

The popliteal pulse is located behind the knee. This pulse can be palpated in the popliteal fossa, which is the area at the back of the knee joint. The popliteal artery, which is a continuation of the femoral artery, runs through this space and is responsible for supplying blood to the lower leg and foot. Finding the popliteal pulse is clinically important, as it provides information about the circulation to the lower extremities. It's typically assessed by bending the knee slightly to help relax the hamstring muscles, which can make the pulse easier to feel. Understanding the anatomy and palpation techniques related to this pulse location is crucial for EMTs in assessing patients for vascular health and conditions. In contrast, the other options refer to pulse points that are anatomically different: behind the ankle refers to the posterior tibial pulse; on top of the foot refers to the dorsalis pedis pulse; and on the wrist refers to the radial pulse. Each of these locations corresponds to different arteries that are assessed for variations in blood flow and health.
