Final answer:
The aide should check Mr. F's care plan or consult with a healthcare professional before removing the splint, as it may be prescribed for continuous use to protect the injury.
Step-by-step explanation:
When Mr. F requests the removal of his splint at bedtime because he believes it is only needed when he is up and about, the aide should first refer to the care plan or seek guidance from a nurse or another healthcare professional.
Splints are often prescribed for continuous use, including during sleep, to immobilize and protect an injured limb.
However, if the healthcare provider has given instructions for the splint to be removed at specific times, such as during rest, the aide should follow those instructions carefully and ensure Mr. F's leg is supported properly after splint removal.
