Final answer:
The nurse should use a bed exit alarm system to minimize the risk of injury to a client with dementia. Raising four side rails should be avoided, wrist restraints should be a last resort, and good lighting should be maintained for safety.
Step-by-step explanation:
To minimize the risk for injury to a client who has dementia, the nurse should implement several interventions that enhance safety. One effective intervention is A) Use a bed exit alarm system. This alarm can alert staff if the client attempts to leave the bed, permitting a prompt response to assist the client and reduce the risk of falls. Additionally, while raising all four side rails might seem like a protective measure, it can actually increase the risk of injury by promoting climbing over the rails, potentially leading to falls. Hence, it is recommended to avoid B) Raising four side rails while the client is in bed. Option C) Applying one soft wrist restraint should be considered a last resort, as restraints can lead to additional problems such as agitation, decreased mobility, and even injury. It is important to use less restrictive means first. Finally, maintaining adequate lighting in the client's room is essential to prevent accidents, therefore option D) Dimming the lights in the client's room is not advisable.
