Which of the following is NOT an example of medical equipment often used by patients?

The correct choice indicates that a wheelchair is not classified as medical equipment typically used by patients in the same sense as the other options listed. A wheelchair is primarily considered a mobility aid or assistive device, helping individuals with mobility challenges navigate their environment. It enables patients to move independently but does not directly provide medical treatment or support specific physiological functions.

In contrast, the other items listed—pacemakers, insulin pumps, and ventilators—are medical devices designed specifically for treating or managing health conditions. A pacemaker regulates heart rhythms for individuals with cardiac issues; an insulin pump delivers insulin to manage diabetes; and a ventilator assists individuals with respiration difficulties. Each of these devices plays a critical role in sustaining life or managing chronic health conditions, distinguishing them from mobility aids like wheelchairs.
