A nurse is caring for a 75-year-old client with Lewy body dementia who has been increasingly agitated and attempting to leave the unit. Which nursing intervention should be the nurse's first priority to ensure client safety?

Validation therapy and a calm, structured environment address emotional needs and safety without restraints, which is the priority for agitated dementia patients. Restraints, sedatives, or room placement are less therapeutic or restrictive alternatives.

Understanding the Priority: Safety in Lewy Body Dementia

When caring for a client with Lewy body dementia (LBD) exhibiting agitation and exit-seeking behavior, the nurse's first priority is to de-escalate the situation using the least restrictive, non-pharmacological approach. This aligns with the foundational NCLEX-RN principle of maintaining client safety while preserving autonomy and dignity. The correct intervention is to implement validation therapy and provide a calm, structured environment.

Why Validation and a Structured Environment are First-Line
Agitation and wandering in LBD are often manifestations of unmet emotional needs, fear, or disorientation rather than intentional disruptiveness. Emotion-oriented interventions (EOIs), which include validation therapy, directly address these underlying psychological and emotional triggers. A systematic review and meta-analysis of randomized controlled trials confirms that EOIs are effective non-pharmacological approaches designed to address the emotional and psychological needs of people with dementia ^[2]. Rather than confronting the client’s reality, validation therapy acknowledges their feelings, reducing the fear and anxiety that fuel the desire to leave. Creating a calm, structured environment further minimizes overstimulation, a common trigger for behavioral and psychological symptoms in LBD. This approach is a cornerstone of high-quality nursing care for neurological disorders, where addressing the patient's immediate psychosocial context is critical for positive outcomes .

Analyzing the Incorrect Options

- Option 2: Apply soft wrist restraints. Physical restraints are a restrictive intervention and are never a first-line choice. Guidelines for geriatric care emphasize the need for tailored management that considers multimorbidity and frailty, explicitly cautioning against interventions that can cause physical harm, increased agitation, or loss of function . Restraints can escalate fear and combativeness in a client with dementia, leading to injury.
- Option 3: Administer prescribed PRN sedative medication immediately. While PRN medications have a role, they are not the initial priority before trying non-pharmacological de-escalation. Sedatives can have paradoxical effects, increase the risk of falls, and worsen cognitive clouding, particularly in the frail geriatric population where evidence-based recommendations guide decision-making to avoid such iatrogenic harm . The nurse must first attempt to manage the behavior environmentally and interpersonally.
- Option 4: Place the client in a room closer to the nurses' station. This is an appropriate environmental modification for safety, but it is a passive surveillance strategy. It does not actively address the client's immediate emotional distress and agitation. The priority is to intervene therapeutically to calm the client’s agitation at its source. Once the client is calmer, relocating them closer to the station is a sound secondary prevention measure.

Connecting to the Underlying Pathology
In LBD, fluctuations in cognition and visual hallucinations are core features that directly contribute to agitation and wandering. A client may attempt to leave the unit because they misperceive a threat or believe they need to fulfill a past obligation. Validation therapy works by entering their reality, reducing the terror that drives the behavior. This is a more immediate and therapeutic safety measure than simply observing the behavior or chemically/physically restricting it. The evidence supports that addressing sleep disturbances and behavioral symptoms with structured, non-pharmacological strategies is both clinically effective and preferred over immediate pharmacotherapy in dementia care .
