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?
  1. Distal
  2. Superior
  3. Anterior
  4. Inferior
  5. Medial
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.
