Final answer:
Restraining the patient with a body restrain may not be the best approach to preventing injury. Other interventions can be tried, such as a bed alarm system and night lights, before considering a restraint.
Step-by-step explanation:
Based on the given information, restraining the patient with a body restrain may not be the best approach to preventing injury. The patient's agitated state during the night could be due to her functional urinary incontinence and poor vision caused by diabetes. Before considering a restraint, other interventions can be tried to ensure her safety. For example, providing a bed alarm system that alerts the nursing staff when she climbs out of bed could be one option. Additionally, using night lights or glow-in-the-dark pathways to guide her to the bathroom might help reduce falls.
