Step-by-step explanation:
The correct answer is 4) Crutches.
All of the other options - gurney, stretcher, and wheelchair - are examples of standard patient transfer equipment commonly used in healthcare settings. A gurney is a type of bed with wheels that can be used to transport patients, while a stretcher is a device used to carry patients horizontally. A wheelchair is a chair with wheels used for mobility support.
On the other hand, crutches are not typically used as patient transfer equipment. They are a mobility aid used by individuals who have difficulty walking or are recovering from lower limb injuries.
