The Physical Therapist (PT) Is Training a Newly Employed PT

The physical therapist (PT) is training a newly employed PT and they are preparing to ambulate with a patient in the hallway using a walker. The new PT asks, "Should we use a wheelchair behind the patient in case the patient gets tired and needs to sit down?" Which response, if made by the PT, would best be classified as nonmaleficence?

A) "I will not go very far, so if the patient does get tired you can just grab a chair."
B) "We usually do not have a wheelchair, so it is best if you walk behind the patient for support."
C) "We do not have one right now, so we will come back later with a wheelchair."
D) "I will get the patient sitting up, while you obtain a wheelchair."
