A nurse is caring for a 78-year-old client with moderate Alzheimer's disease who has been exhibiting increased agitation and wandering behavior during the evening hours. The client's family reports that these behaviors have worsened over the past week. What is the most appropriate initial nursing intervention?

Establishing a consistent evening routine with calming activities is the most appropriate initial intervention for sundowning in Alzheimer's disease, as it addresses underlying causes non-pharmacologically. Other options involve restrictive measures or medications that are not first-line.

Core Nursing Explanation Key Concept Analysis: This question assesses the management of Sundowning in a patient with Alzheimer's disease. Sundowning refers to increased confusion, agitation, and wandering that typically occurs in the late afternoon and evening. The underlying causes are often related to fatigue, sensory overload or deprivation, disruption of the circadian rhythm, and unmet needs. The core nursing principle is to use non-pharmacological interventions as the first-line approach to manage behavioral and psychological symptoms of dementia (BPSD), as they address the root cause without the risks associated with medications or restraints.

Answer Rationale: Key Point! Option ④ is correct because establishing a consistent evening routine is a fundamental, evidence-based, non-pharmacological strategy. Consistency reduces anxiety and confusion by creating a predictable environment. Calming activities (e.g., soft music, gentle massage, quiet conversation) help reduce overstimulation and promote relaxation, directly addressing the triggers for sundowning. This intervention aligns with the nursing process by first assessing the pattern of behavior and then planning a structured, therapeutic environment.

Distractor Analysis:
Watch out for confusion! Option ① (Administer PRN lorazepam): While benzodiazepines like lorazepam may be used in some cases, they are not a first-line or initial intervention for dementia-related agitation. They can cause paradoxical agitation, increase fall risk, worsen confusion, and are associated with higher mortality in older adults. Pharmacological interventions are considered only after non-pharmacological methods have been tried and failed, or if the patient poses an immediate danger to self or others.
Option ② (Restrict to their room): This is a form of physical restraint and seclusion, which is ethically and legally problematic. Restriction increases frustration, fear, and agitation, and can lead to injury. It violates the principle of providing care in the least restrictive environment.
Option ③ (Increase environmental stimulation): This is counterproductive. Sundowning is often exacerbated by overstimulation, fatigue, and sensory overload. Adding more noise from TV and music would likely increase confusion and agitation, not alleviate it.

Related Concepts: Management of BPSD follows a tiered approach: 1) Identify and address triggers (pain, hunger, full bladder, infection), 2) Implement non-pharmacological strategies (routine, redirection, validation therapy), 3) Use pharmacological agents as a last resort. Always rule out delirium (a sudden change in mental status often due to infection, medication, or metabolic imbalance) as a cause for acute behavioral changes, as mentioned in the family's report of worsening over the past week.
Concept Summary • Sundowning: Evening agitation/confusion in dementia; manage with routine, reduced stimuli. • Non-Pharmacological First: Always the initial approach for BPSD (behavioral and psychological symptoms of dementia). • Avoid Restraints: Physical (restraints) and chemical (sedatives) restraints increase risk and agitation. • Assess for Delirium: Sudden change? Think infection (UTI), medication side effect, pain.
Side-by-Side Comparison!

Intervention Type	Example	Rationale & Use	Risks/Cautions
Non-Pharmacological (First-Line)	Consistent routine, calming activities, massage, music therapy, redirection.	Addresses root causes (anxiety, confusion); safe, person-centered.	Requires staff time and consistency; may not work for severe agitation.
Pharmacological (Last Resort)	Atypical antipsychotics (e.g., risperidone), mood stabilizers.	For severe symptoms where there is danger to self/others after other methods fail.	Black box warnings for increased mortality in elderly dementia patients; side effects.
Avoid / Inappropriate	Benzodiazepines (lorazepam), physical restraints, seclusion.	May be used in acute, specific settings (e.g., procedural anxiety) but not for routine BPSD management.	High risk of falls, paradoxical reactions, worsening cognition, ethical violations.

Anatomy, Physiology & Pharmacology Points • Circadian Rhythm Disruption: In Alzheimer's, damage to the suprachiasmatic nucleus (the brain's "body clock") in the hypothalamus contributes to sleep-wake cycle disturbances and sundowning. • Neurotransmitters: Agitation may be linked to imbalances in acetylcholine (decreased) and dopamine/norepinephrine. • Lorazepam Mechanism: A benzodiazepine that enhances GABA (an inhibitory neurotransmitter) action. In the elderly brain, it can cause excessive sedation, confusion, and loss of inhibition leading to paradoxical agitation.
Memory Tips • ABCs of Dementia Care: Assess for triggers, Be consistent with routine, Create a calm environment. • Drug Warning Mnemonic: "Benzos Bad for Brains" in the elderly. • Sundowning Strategy: Think "Sun Down = Structure & De-stimulate."
High-Frequency NCLEX Topics NCLEX heavily tests the least restrictive intervention principle and the non-pharmacological first approach for behavioral issues in dementia, psychiatric care, and geriatrics. You will often be asked to choose the initial, first, or most appropriate nursing action, which is almost always an assessment or a therapeutic communication/intervention before administering medication.
Watch Out for Question Variations! • Shift from Intervention to Assessment: "The nurse notes increased agitation. What should the nurse assess first?" (Answer: Assess for pain, infection, full bladder, environmental triggers). • Priority Setting: "The client is agitated and trying to climb out of bed. Which action should the nurse take first?" (Answer: Ensure client safety by staying with the client, using a bed alarm, or gently redirecting—not immediately administering medication). • Family Education: "What should the nurse teach the family about managing evening agitation at home?" (Answer: Establish a predictable bedtime routine, limit caffeine, ensure daytime light exposure/exercise).

Nursing Clinical Practice Guide Clinical Scenario: You are the night shift nurse on a geriatric unit. Mr. Johnson, 78 with Alzheimer's, becomes increasingly restless around 7 PM each evening. He paces the hallways, mumbles incoherently, and becomes resistant when staff try to guide him back to his room. His daughter mentions he seems more confused this week.

Nursing Intervention Strategy: 1. Assessment: First, rule out acute causes. Perform a focused assessment: Check for signs of UTI (cloudy urine, frequency), pain (grimacing, guarding), constipation, hunger, or thirst. Review his medication list for new drugs or side effects. Assess his pain level using a valid scale for non-verbal patients (e.g., PAINAD scale). 2. Planning & Implementation: • Evening Routine: Collaborate with the day shift to establish a consistent wind-down routine starting at 6 PM. This includes: a warm, caffeine-free drink; soft, familiar music; dimming overhead lights; and a quiet activity like looking at family photo albums. • Environment: Reduce noise and clutter. Ensure pathways are clear for safe wandering. Use nightlights to reduce shadows that can cause fear. • Communication: Use simple, calm statements. Validate his feelings ("It seems like you're looking for something. Let's sit here together for a moment.") instead of arguing or using logic. • Documentation: Chart the specific behaviors, antecedents (what happened before), interventions tried, and the client's response. This tracks patterns and effective strategies. 3. Evaluation & Communication: Evaluate if the routine reduces agitation. Report findings and effective strategies to the care team and family. If behaviors escalate to the point of being dangerous, follow facility protocol, which may involve a team approach and, as an absolute last resort with a specific order, a pharmacological intervention.
Patient Safety and Precautions: • Fall Prevention: Agitation and wandering increase fall risk. Ensure the bed is in low position, floors are dry, and appropriate supervision is provided. • Medication Caution: If a PRN medication like lorazepam is administered, monitor closely for respiratory depression, excessive sedation, and increased confusion. It should not be used as a routine "chemical restraint." • Avoid Confrontation: Never argue with a confused patient. It escalates agitation. Redirect and distract instead.
Nursing Procedure & Medication Flow Non-Pharmacological Behavioral Management Procedure: 1. Identify the behavior and its potential trigger. 2. Approach the patient calmly from the front, identify yourself. 3. Ensure a safe environment (remove hazards). 4. Use therapeutic communication (validation, redirection). 5. Offer a preferred, calming activity. 6. If unsuccessful, provide supervised space for safe wandering. 7. Document the entire episode: A-B-C (Antecedent, Behavior, Consequence/Intervention).
If Medication is Required (by provider order after other methods fail): 1. Verify order, indication, and dose. Check for allergies. 2. Perform a pre-medication assessment (vital signs, level of consciousness). 3. Administer as prescribed. 4. Monitor vital signs, respiratory status, and level of sedation per protocol (e.g., every 15-30 minutes initially). 5. Implement fall precautions (side rails up, bed alarm on).
A Word from Your Senior Nurse Caring for patients with dementia requires immense patience and a shift in perspective. Your goal isn't to "fix" their confusion but to enter their world and provide comfort and safety. That moment when a simple, consistent routine or a familiar song calms a agitated patient is a powerful reminder of the impact of skilled nursing care. On the NCLEX, they are testing your clinical judgment—can you see past the behavior to the underlying need and choose the safest, most therapeutic response? Remember: Connect, don't correct. Comfort, don't confront. This mindset is the heart of excellent dementia care and will guide you to the right answer.
