Acute Confusion (Delirium) Nursing Care Plan

1. Detecting delirium and establishing baseline

• Ask family or the care facility what the patient's normal cognition is; without a baseline, delirium cannot be recognized reliably.
• Screen with a validated tool such as the Confusion Assessment Method at least once per shift for at-risk patients, since fluctuation means a single normal check proves nothing.
• Test attention specifically — months of the year backward, digit span — rather than asking only orientation questions.
• Look actively for the quiet, withdrawn hypoactive form; a compliant, sleepy patient is often delirious rather than 'settled'.
• Document specific observed behaviors and times rather than the word 'confused', so fluctuation and trend are visible to the team.

2. Searching for and treating the cause

• Check oxygen saturation and blood glucose immediately — both are instantly correctable causes of altered mentation.
• Assess for infection including urinary and respiratory sources, remembering that older adults may present with confusion and no fever.
• Perform a bladder scan and assess for constipation and fecal impaction; retention and impaction are common, easily missed and quickly reversible.
• Evaluate pain carefully — untreated pain causes delirium, and non-verbal patients need an observational pain scale.
• Review every medication with the pharmacist and provider, targeting anticholinergics, sedatives, hypnotics and recently added drugs.
• Take an alcohol and benzodiazepine history and anticipate withdrawal in the first 24–72 hours of admission.
• Check electrolytes, renal and liver function and relevant drug levels, and report abnormalities promptly.

3. Providing orientation and a therapeutic environment

• Ensure glasses and hearing aids are in place and working; correctable sensory deficit is one of the strongest and simplest reversible contributors.
• Place a visible clock and calendar in view and reorient conversationally at each interaction rather than quizzing the patient.
• Keep assignments consistent so the same faces recur, and introduce yourself by name and role every time.
• Encourage family to bring familiar photographs and objects and to visit during the day.
• Reduce noise and clutter, keep the room adequately lit during the day and dim at night, and avoid moving the patient between rooms.
• Speak slowly in short sentences, one instruction at a time, allowing time to respond.
• Do not argue with delusions or hallucinations; acknowledge the feeling, state your own perception simply, and redirect.

4. Maintaining safety without restraint

• Keep the bed low, brakes locked, call light within reach and frequently used items close by, and use a bed or chair alarm as available.
• Place the patient where they can be observed easily and increase rounding frequency rather than relying on alarms.
• Offer scheduled toileting every two hours; many falls happen during an unassisted attempt to reach the bathroom.
• Use physical restraint only when there is imminent danger and every alternative has failed — restraint increases agitation, injury, deconditioning and delirium duration.
• If restraints are unavoidable, apply the least restrictive type, check circulation and skin frequently, release and reposition on schedule, and reassess for removal at least every shift.
• Camouflage or secure lines and tubes, and discontinue any catheter, telemetry lead or infusion that is no longer needed.

5. Restoring sleep, mobility and physiologic balance

• Protect nighttime sleep by clustering care, silencing non-essential alarms, and avoiding routine overnight vital signs and blood draws where clinically safe.
• Promote daytime wakefulness with light, conversation and activity, and discourage long daytime naps to correct day-night reversal.
• Mobilize early and often — sitting up for meals, walking several times daily — since immobility both worsens and prolongs delirium.
• Offer fluids frequently and monitor intake, output and weight; even mild dehydration impairs cognition in older adults.
• Assist with meals, provide preferred foods and ensure dentures are in place; poor intake compounds every other factor.
• Provide oral care and prevent aspiration in drowsy patients.

6. Pharmacologic management

• Treat the cause and use non-drug measures first; no medication reverses delirium itself.
• Reserve low-dose antipsychotics for severe agitation that threatens safety, use the smallest effective dose for the shortest time, and monitor for QT prolongation and extrapyramidal symptoms.
• Avoid benzodiazepines, which usually deepen confusion — the exception is alcohol or sedative withdrawal, where they are the treatment.
• Avoid anticholinergics including diphenhydramine, and question every new sedating medication.
• Provide adequate scheduled analgesia; undertreated pain is a more common cause of agitation than any psychiatric process.
• Reassess and taper any psychoactive medication daily rather than continuing it by default at discharge.

7. Supporting family and planning follow-up

• Explain that delirium is caused by physical illness, is usually temporary, and is not the patient 'losing their mind'.
• Teach family how to help: calm presence, simple sentences, familiar objects, orienting statements and daytime visits.
• Warn that recovery can lag behind resolution of the cause by days to weeks, and that fluctuation during recovery is expected.
• Arrange cognitive reassessment after discharge, since delirium may unmask underlying dementia.
• Document the episode, the identified cause and the medications implicated so future admissions can prevent recurrence.

What are the nursing care goals for Acute Confusion?

The client will return to their documented baseline level of orientation and attention. The client will remain free of injury, with no falls and no dislodgement of lines or tubes. The underlying cause will be identified and treated within the current admission. The client will re-establish a normal day-night sleep pattern. The client will maintain adequate hydration, nutrition and elimination. The family will describe delirium, its expected course, and how to support the patient at home.

What should you assess in a patient with Acute Confusion?

Family reporting the person is 'not themselves' or different from baseline; Patient reporting seeing or hearing things others do not; Expressions of fear, suspicion or belief that staff intend harm; Complaints that are vague or inconsistent, or inability to describe symptoms; Reports of poor sleep, nightmares or day-night reversal; Inability to sustain attention: loses track mid-sentence, cannot recite months backward, easily distracted; Disorientation to time and place, with fluctuation from hour to hour; Agitation, pulling at lines and tubes, attempts to climb out of bed — or the opposite, lethargy and withdrawal; Disorganized or rambling speech and altered sleep-wake cycle with evening worsening; Vital signs, oxygen saturation, temperature and point-of-care glucose; Bladder scan for retention, last bowel movement, intake and output, weight; Laboratory work: complete blood count, electrolytes, urea and creatinine, glucose, urinalysis and culture, liver function, drug levels; Full medication review including newly started, recently stopped and over-the-counter agents
