Final answer:
The nurse will instruct the adolescent fitted with a Milwaukee brace to follow the prescribed schedule for wearing the brace consistently.
Step-by-step explanation:
When an adolescent is fitted with a Milwaukee brace, the nurse will provide the instruction to 'follow the prescribed schedule for wearing the brace consistently'. This is because the Milwaukee brace is a rigid spinal orthosis designed to treat scoliosis, and it needs to be worn for a certain amount of time every day to be effective. Wearing the brace only during physical activities or avoiding wearing it during sleep would not provide the necessary support and correction for the spine. Additionally, ensuring the brace fits snugly is important, but it should be done according to the healthcare provider's guidance to prevent any complications.
