Correct Answer is C

Explanation

Choice A reason: While education is important, it is not the priority for a client with significantly progressed dementia, as their ability to learn new information is likely impaired.

Choice B reason: Support is crucial for clients with dementia, but it is not the immediate priority in the context of safety concerns.

Choice C reason: This is the correct choice. Safety is the priority for clients with significantly progressed dementia due to increased risk of harm from confusion, wandering, and other behaviors.

Choice D reason: Cognitive interventions may be part of the treatment plan, but they are not the priority when compared to ensuring the client's safety.

A. A client with a blood glucose level of 110 mg/dL (6.1 mmol/L). B. A client who sustained a fractured femur in a motor vehicle crash. C. An adult client being prepared for a laparoscopic cholecystectomy. D. An older adult client with sepsis from a urinary tract infection.

Correct Answer is D

Explanation

Choice A reason: This choice is incorrect. A blood glucose level of 110 mg/dL is within normal range and does not significantly increase the risk of delirium.

Choice B reason: While a fractured femur can be painful and stressful, it does not pose the highest risk for delirium compared to sepsis.

Choice C reason: Preparation for surgery can be a risk factor for delirium, but it is not as high a risk as sepsis in an older adult.

Choice D reason: This is the correct choice. Older adults with sepsis are at a high risk for delirium due to the systemic infection and its impact on overall health.
