The nurse applies a blood pressure cuff around a client's left thigh. To measure the client's blood pressure, where should the diaphragm of the stethoscope be placed? (Mark the location on one of the images.)

To measure blood pressure from the left thigh, the diaphragm of the stethoscope should be placed over the popliteal artery, which is located behind the knee. This placement allows you to auscultate the Korotkoff sounds accurately when measuring thigh blood pressure.
