Final answer:
The client who performs over 75% of the dressing task independently, with some help, requires minimal assistance according to the defined levels of assistance.
Step-by-step explanation:
If a client performs 75% or more of the task during the dressing of the upper extremities, such as zipping, buttoning, and clasping, and requires a helper for the activity, the level of assistance needed is defined as minimal assistance. Minimal assistance means that the client is able to do most of the activity by themselves but may require a little help to complete it. In this case, since the client is performing the majority of the task, they are not dependent on extensive or total assistance, and it requires less than moderate assistance.
When dressing the upper extremities, if the client performs 75% or more of the task, this indicates that they have some level of independence in dressing themselves. However, they still require some assistance in specific actions such as zipping, buttoning, and clasping. This level of assistance falls under the category of moderate assistance.
