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: Sims’ position is for rectal exams, not central catheter insertion. Trendelenburg or supine is used, so this is incorrect for TPN prep.

Choice B reason: Verifying TPN amount is ongoing care, not insertion prep. Initial placement confirmation via x-ray takes precedence over infusion monitoring here.

Choice C reason: Clean technique risks infection in central lines; sterile is required. This compromises TPN safety, making it an incorrect preparatory step.

Choice D reason: Chest x-ray confirms catheter tip placement in the vena cava for TPN. It’s a critical prep step to ensure safe administration begins.

Choice A reason: Memory loss disrupting ADLs is a dementia hallmark, as progressive neuronal death impairs recall and function. Scientifically, this defines dementia (e.g., Alzheimer’s), distinguishing it from acute states, aligning with chronic cognitive decline impacting daily life per neurological evidence.

Choice B reason: Acute confusion is delirium, not dementia, which develops gradually. Scientifically, dementia’s insidious onset contrasts with delirium’s rapid shift, driven by reversible causes (e.g., infection), making this uncharacteristic of dementia’s chronic progression.

Choice C reason: Illusions (misinterpretations) may occur in dementia but aren’t defining; memory loss is core Jr.. Scientifically, perceptual errors are secondary to cognitive decay, not a primary expectation, as dementia targets memory over sensory processing initially.

Choice D reason: Catatonia, motor immobility, is tied to psychiatric or neurological crises, not dementia. Scientifically, dementia affects cognition, not movement primarily, making this rare and untypical compared to memory-driven functional loss in its pathology.
