A nurse is assisting with the care of a client who has delirium. The client is disoriented and restless. Which of the following conditions should the nurse identify as a risk factor for delirium?

Choice A reason: Family history informs genetic risks, not current mobility needs for therapy. Scientifically, it’s less relevant than functional data, as physical therapy focuses on present deficits, not hereditary patterns, making this secondary for referral purposes.

Choice B reason: Prior medications provide context but don’t detail current physical status for therapy goals. Scientifically, recent assessments outweigh past drug use, as therapists need functional baselines, not historical pharmacology, for effective planning.

Choice C reason: Physical assessment findings (e.g., strength, range of motion) directly inform therapy needs, setting baselines for intervention. Scientifically, this data drives rehabilitation plans, aligning with evidence-based practice to target specific deficits for mobility recovery.

Choice D reason: Insurance claims are administrative, not clinical, data. They don’t guide therapy goals or interventions. Scientifically, financial details are irrelevant to physical assessment, making this inappropriate for a referral focused on functional restoration.

Choice A reason: Diminished pulses signal compromised circulation, a critical cast complication like compartment syndrome. This risks tissue necrosis or amputation if untreated, prioritizing it scientifically, as arterial flow disruption demands immediate intervention to preserve limb viability per vascular assessment standards.

Choice B reason: Ecchymosis suggests bruising, possibly from cast pressure, but isn’t immediately life-threatening like poor circulation. It’s a secondary concern, manageable later. Scientifically, it indicates trauma, not acute vascular emergency, ranking lower in urgency per cast complication protocols.

Choice C reason: Muscle spasms may indicate irritation or pressure, but they’re less urgent than absent pulses. Pain is common in casts, not always critical. Scientifically, this suggests nerve or muscle stress, not imminent tissue loss, making it a lower priority for immediate action.

Choice D reason: One fingerbreadth space is normal, preventing tightness, not a concern. It’s ideal fit, not a problem. Scientifically, this aligns with safe cast application, lacking urgency compared to circulatory threats, as it supports, rather than jeopardizes, limb health.
