Final answer:
If a client can dress their upper extremities 50-74% and complete 2 or 3 out of 4 steps, moderate assistance is needed to ensure their safety and encourage independence.
Step-by-step explanation:
When a client completes 50-74% of the dressing of the upper extremities (UE) and achieves 2 or 3 out of 4 steps, it is indicated that they require moderate assistance. This is due to the client not being able to complete the task independently yet showing considerable ability to perform the task with some help. Providing this level of assistance ensures safety and encourages independence where possible.
