What action should the nurse take for an older client with Alzheimer’s disease who experiences sleep deprivation?

Leaving a dim light on in the room is a beneficial approach for an older client with Alzheimer’s disease who is experiencing sleep deprivation. This action can help create a comforting and safer environment, reducing anxiety and disorientation that may occur in the dark. Individuals with Alzheimer's often have difficulty interpreting their surroundings, so a soft light can provide reassurance and assist with navigation during night-time awakenings without overwhelming them.

In contrast, closing the client’s door during the night may increase feelings of isolation or fear, as it can create confusion about the environment. Applying a vest restraint can pose safety risks and ethical concerns, as restraints can lead to physical harm and diminish the client’s autonomy. Administering prescribed sedative medication might be considered, but it's usually viewed as a last resort, given the potential for side effects and diminished alertness, which can complicate the client’s care and increase the risk of falls. Thus, leaving a dim light on is a proactive, supportive measure to help manage sleep deprivation while fostering a sense of security.
