Which of the following activities performed during psychomotor client teaching requires gross motor skills?

Walking with crutches indeed requires gross motor skills, which involve large muscle movements and coordination of the body as a whole. In this context, the use of crutches not only involves the strength and coordination of the legs but also engaging the upper body to support and balance during movement.

Gross motor skills encompass actions such as walking, running, and jumping, which require significant strength and coordination of larger muscle groups. In the case of using crutches, the client must demonstrate the ability to shift their weight, maintain balance, and use the crutches effectively to navigate their environment, all of which are core components of gross motor skills.

The other activities listed primarily require fine motor skills. For example, administering an intradermal injection and applying an adhesive bandage involve precise hand movements and coordination of smaller muscles, while using a manual wheelchair requires some gross motor skills but is more closely associated with fine motor control for steering and maneuvering.
