An older patient diagnosed with severe, late-stage dementia no longer recognizes family members. The family asks how long it will be before this patient recognizes them when they visit. What is the nurse's best reply?

Choice A reason: This is an example of appropriate nursing intervention and "verbal de-escalation." Convincing a patient to return to a unit through persuasion does not constitute illegal confinement, especially when the patient is under an involuntary hold due to the risk of self-harm or suicide.

Choice B reason: Restraining a patient without an immediate medical order or failing to obtain one in a timely manner according to hospital policy constitutes false imprisonment. While emergency restraint is sometimes permitted for immediate safety, keeping a patient restrained until the "next morning" without proper authorization violates their legal rights.

Choice C reason: Preventing an involuntarily committed patient with homicidal ideation from leaving is a legal requirement under the "duty to protect" and "commitment" laws. Using established security protocols to maintain the confinement of a dangerous individual is a lawful exercise of the facility's authority and duty.

Choice D reason: This action is an example of an "assault" (the threat of harm) and potentially an "illegal use of seclusion" as a punishment, but it does not meet the technical definition of false imprisonment in the same way that unauthorized physical mechanical restraint does in choice B.

Choice A reason: Placing the bed in the lowest position is a primary falls prevention strategy for patients with dementia. It minimizes the distance to the floor if the patient attempts to exit the bed unassisted, thereby reducing the impact and severity of potential injuries while maintaining the patient's dignity and autonomy.

Choice B reason: Restricting fluids after 1800H (6:00 PM) is generally discouraged as it can lead to dehydration and urinary tract infections in the elderly. While it might reduce nocturia, it does not address the underlying cognitive impairment causing the patient to wander or attempt to exit the bed during the night.

Choice C reason: The application of physical restraints, especially on a PRN (as needed) basis, is ethically and legally restricted. Restraints often increase agitation in patients with dementia and can lead to serious injuries or strangulation. They are considered a last resort and require specific, time-limited physician orders.

Choice D reason: Using four side rails is often classified as a form of physical restraint. For a patient with dementia, side rails can create a "caging" effect, leading the patient to attempt to climb over them. This significantly increases the risk of falling from a greater height, leading to more severe head or hip injuries.
