A nurse is caring for an 82-year-old client with moderate Alzheimer's disease who has been experiencing increased agitation and wandering behavior during evening hours. Which nursing intervention should be the priority to manage this client's sundown syndrome?

Non-pharmacological interventions like structured activities and consistent lighting (option 2) are first-line for sundown syndrome. Options 1, 3, and 4 are inappropriate due to risks of sedation, restriction, or increased agitation.

Core Nursing Explanation This question tests the priority nursing intervention for managing sundown syndrome in a client with Alzheimer's disease. Sundowning refers to a state of increased confusion, agitation, and behavioral problems that typically occur in the late afternoon or evening. The core principle is that Key Point! non-pharmacological, environmental, and behavioral strategies are the first-line and preferred approach for managing behavioral and psychological symptoms of dementia (BPSD), including sundowning. Key Concept Analysis The question centers on Evidence-Based Nursing (EBN) for dementia care. The pathophysiology involves the degeneration of brain regions that regulate circadian rhythms (the sleep-wake cycle) and process environmental cues. As daylight fades, the aging brain with Alzheimer's has more difficulty interpreting sensory input, leading to disorientation and fear, which manifests as agitation and wandering. The priority is to create a safe, predictable, and calming environment to reduce these triggers. Answer Rationale Option ② is correct because it directly addresses the root causes of sundowning through structured, non-pharmacological means.
Key Point! Structured evening activities (e.g., simple puzzles, folding laundry, listening to calming music) provide a sense of purpose and focus, reducing boredom and anxiety that fuel wandering.
Key Point! Maintaining consistent lighting helps mitigate the confusion caused by shadows and dim light. It supports the client's impaired circadian rhythm and reduces environmental triggers of fear and disorientation. This approach aligns with the nursing principle of promoting safety and maximizing patient function with the least restrictive interventions. Distractor Analysis
Watch out for confusion! Option ①: While lorazepam (a benzodiazepine) may be prescribed for severe agitation, it is not the first-line or priority intervention for an elderly client with dementia. These medications carry significant risks, including increased sedation, confusion, falls, and paradoxical agitation. Pharmacological interventions are considered only after non-pharmacological strategies have been optimized and if the behavior poses a significant safety risk.
Option ③: Physically restricting or secluding a client increases feelings of fear, powerlessness, and agitation. It is a form of restraint and violates ethical nursing principles. Wandering is a behavior that needs redirection, not punishment.
Option ④: Caffeine is a central nervous system stimulant. Increasing intake in the afternoon would directly counteract the goal of promoting evening calm and would likely exacerbate agitation, anxiety, and insomnia, worsening the sundowning behavior. Related Concepts This scenario integrates concepts of geriatric pharmacology (increased sensitivity to psychoactive drugs), therapeutic communication for confused clients, and the nursing process where assessment of triggers leads to planning environmental modifications. Concept Summary
Sundown Syndrome: Worsening of confusion/agitation in dementia patients during late day/evening.
First-Line Management: Non-pharmacological, environmental modifications.
Core Interventions: Maintain routines, ensure adequate lighting, reduce noise/clutter, provide structured activities.
Pharmacology Caution: Antipsychotics/benzodiazepines are last-resort due to high risk of adverse effects in elderly. Side-by-Side Comparison!

Intervention Type	Example	Rationale & Use	Risks/Cautions
Non-Pharmacological (First-Line)	Structured activities, consistent lighting, music therapy, gentle reorientation.	Addresses environmental/sensory triggers. Promotes safety and autonomy.	Requires staff time and consistency. May not stop all acute agitation.
Pharmacological (Last-Resort)	Atypical antipsychotics (e.g., risperidone), benzodiazepines (e.g., lorazepam PRN).	For severe agitation posing immediate danger to self/others after other methods fail.	High risk: sedation, falls, stroke, mortality. Requires informed consent and frequent monitoring.

Anatomy, Physiology & Pharmacology Points
Circadian Rhythm Dysregulation: The suprachiasmatic nucleus (SCN) in the hypothalamus is often damaged in Alzheimer's, disrupting sleep-wake cycles.
Benzodiazepine Mechanism: Enhance GABA (an inhibitory neurotransmitter) causing sedation. In elderly, they have a prolonged half-life, increasing fall and confusion risk.
Antipsychotic Black Box Warning: Atypical antipsychotics carry an FDA black box warning for increased risk of death in elderly patients with dementia-related psychosis. Memory Tips

Structure the evening.
Use consistent lighting.
Noise reduction.
Divert with simple activities.
Offer reassurance.
Watch for triggers.
Never restrain first.

Mnemonic: "Lights and Routine Keep Calm at Night" – emphasizes the two key elements of the correct answer. High-Frequency NCLEX Topics NCLEX frequently tests the priority of non-pharmacological over pharmacological interventions for dementia behaviors. You must know that restraint (physical or chemical) is a last resort. Questions often present a scenario with an agitated elderly patient and ask for the "first," "initial," or "priority" action—the answer is almost always an assessment or a calming, non-restrictive intervention. Watch Out for Question Variations!

• Instead of "priority intervention," the question may ask: "The nurse is developing a plan of care. Which goal is most appropriate?" (Answer: Client will participate in evening activities without agitation.)
• The scenario might shift to a client already on medication: "A client with Alzheimer's on risperidone presents with shuffling gait and stiff movements. What is the nurse's priority action?" (Answer: Assess for extrapyramidal symptoms (EPS) and notify the provider—focusing on medication side effect monitoring.)
• It could combine sundowning with fall risk: "Which intervention addresses both sundowning agitation and fall prevention?" (Answer: Implementing a supervised walking program in a secure area during the day to reduce evening restlessness.)

Nursing Clinical Practice Guide Clinical Scenario: You are the night shift nurse on a geropsychiatric unit. Mr. Johnson, 82, with moderate Alzheimer's, begins pacing the hallways at 7 PM, trying to open doors and muttering about "going home to make dinner." He appears anxious and does not respond to simple verbal redirection. Nursing Intervention Strategy 1. Assessment: Quickly assess for immediate safety risks (is he near an exit? does he have IV lines?). Note the time and any potential triggers (change in staff, recent nap, dimmed lights). 2. Intervention:

• Environmental: Turn on additional lights in the hallway and his room to minimize shadows. Reduce overhead paging and other sudden noises.
• Behavioral: Approach calmly. Use validation therapy ("It must feel important to get home to make dinner. Can you help me set this table for our snack here?"). Redirect to a structured, familiar activity: "Mr. Johnson, I need help folding these towels. Your help would be wonderful." Guide him to a supervised activity area.
• Collaborative: Ensure the nursing assistant knows to engage him in a simple, repetitive task. Consider offering a warm, non-caffeinated beverage (like milk) which can have a calming effect.

3. Evaluation: Monitor his response. Does the pacing slow? Does he engage in the activity? Document the specific intervention used and its effectiveness to ensure consistency across shifts. Patient Safety and Precautions

• Chemical Restraint Caution: Administering PRN lorazepam should only be done per a specific protocol for extreme agitation unresponsive to other measures. You must document a clear rationale (e.g., "aggressive behavior posing imminent danger") and monitor closely for respiratory depression and falls.
• Physical Safety: Ensure the environment is "wander-proof" with disguised door locks and safe walking paths. Never leave an agitated, wandering client unattended.
• Family Education: Teach family members about sundowning and the importance of maintaining a calm, well-lit evening routine at home.

Nursing Procedure & Medication Flow Procedure for Managing Agitation (Non-Pharmacological First): 1. Ensure personal safety and have sufficient staff. 2. Approach slowly from the front, speak in a low, calm voice. 3. Use simple, concrete statements. Avoid arguing or complex logic. 4. Offer a distraction or redirect to a preferred activity. 5. If unsuccessful, provide personal space but maintain observation. 6. Only as a last resort, administer medication per order and facility policy, followed by 1:1 monitoring. Medication Administration (if required):

• Drug: Lorazepam 0.5 mg PO/IM PRN agitation.
• Precautions: Check for allergies. For elderly, "start low and go slow." Assess fall risk before and after administration. Monitor for paradoxical reaction (increased agitation).
• Documentation: Must include: Behavior preceding administration, non-pharmacological attempts made, patient response post-administration, and ongoing safety monitoring.

A Word from Your Senior Nurse Caring for a sundowning patient tests your patience and creativity. Remember, the agitation is not personal—it's a symptom of a damaged brain struggling with a confusing world. Your role is to be that steady, calming anchor. Turning on a light, offering a simple task, or just sitting quietly with them can be more powerful than any pill. On the NCLEX, they want nurses who think like this: safety first, humanity always, medication as a carefully considered tool, not a first resort. When you see "priority" in a behavioral question, think "What can I do to make the environment safer and less frightening?" That mindset will guide you to the right answer every time.
