Final answer:
To correctly measure for axillary crutches, measure from the axilla (armpit) to the floor, ensuring a one to two-inch gap between the crutch top and axilla when standing.
Step-by-step explanation:
To measure for axillary crutches, the correct position is C) From the axilla (armpit) to the floor. This measurement ensures that the crutches are the correct height for the individual's body. The crutch should be adjusted so that there is a one to two-inch gap between the top of the crutch and the axilla when the person is standing upright, to prevent pressure on the underarm nerves and blood vessels. Therefore, option A) From the wrist to the floor, B) From the elbow to the wrist, and D) From the shoulder to the elbow are incorrect measurements for axillary crutches.
