When a tourniquet is applied to a patient’s upper arm (above the elbow), circulation will be cut off to parts of the arm that are best described with which term?
Explanation
Answer - A - If a tourniquet is applied to a patient’s upper arm, circulation will be cut off to parts of the arm that are distal. Although using the term “distal” typically refers to a point that is farther away from a reference point, in the case of a tourniquet, the reference point is the heart. Thus, a tourniquet on the upper arm stops circulation to the distal parts of the arm, such as the forearm.
