A nurse is providing education to a client who is scheduled for a left knee arthroplasty. Which of the following statements regarding informed consent indicates client understanding of the teaching?

Choice A reason: Warming blood products prevents hypothermia during transfusion but is not the priority in a trauma patient. Airway management takes precedence, as oxygenation is critical to survival. Administering blood products comes later in the trauma algorithm, after securing the airway and stabilizing breathing, making this action secondary.
Choice B reason: Establishing a patent oral airway is the first priority in trauma care, following the ABCs (Airway, Breathing, Circulation). A clear airway ensures oxygenation, critical for preventing hypoxia in a patient with multiple injuries. Without a patent airway, other interventions are ineffective, as oxygen delivery is essential for survival and organ function.
Choice C reason: Creating a sterile field for wound care is important to prevent infection but is not the first priority in a trauma patient. Airway and breathing take precedence, as immediate life-threatening issues like hypoxia or shock must be addressed before wound care, making this action lower in priority.
Choice D reason: Administering IV fluids to maintain blood pressure is part of the circulation phase in trauma care but follows airway and breathing stabilization. Without a patent airway, fluid administration cannot address hypoxia, a primary cause of mortality in trauma. This action is secondary to ensuring airway patency.

Choice A reason: Performing ADLs independently is not a specific indicator of donepezil’s effectiveness, as it treats cognitive symptoms in Alzheimer’s, not physical function. While improved cognition may indirectly aid ADLs, this outcome is too broad and not directly tied to the medication’s primary action, making it incorrect.
Choice B reason: Increased food intake is not an expected outcome of donepezil, which targets acetylcholinesterase to improve cognitive function in Alzheimer’s. Appetite changes are unrelated to its mechanism, and this finding does not indicate effectiveness, making it an incorrect measure of the drug’s impact.
Choice C reason: Enhanced mood is not a primary effect of donepezil, which focuses on slowing cognitive decline. While mood may improve indirectly, it is not a direct indicator of efficacy. Other medications address mood in Alzheimer’s, making this finding less relevant and incorrect.
Choice D reason: Improved short-term memory is a key indicator of donepezil’s effectiveness, as it increases acetylcholine levels to slow cognitive decline in Alzheimer’s. Enhanced memory reflects the drug’s intended action, aligning with clinical expectations, making this the correct measure of therapeutic success.
