Final answer:
Miss Hayes's current condition upon waking from a nap is likely confusion and difficulty in recognizing her surroundings or familiar faces, indicative of Alzheimer's disease's effects on the brain, particularly in regions associated with memory and recognition.
Step-by-step explanation:
The current condition of Miss Hayes, a resident with Alzheimer's disease, upon waking from her nap would possibly be that she is confused and does not recognize her room or anyone (Option B). Alzheimer's disease often impairs memory and cognitive functioning. Based on the symptoms described in the scenario, such as her irritability, memory lapses, and disorientation, Miss Hayes's Alzheimer's has likely affected parts of her brain responsible for memory and recognition, which include the hippocampus and other areas associated with cognitive processing.
The development of amyloid plaques and neurofibrillary tangles, as mentioned in Figure 11.9.1, are hallmarks of Alzheimer's that lead to loss of synapses and neuron death. This contributes to the confusion and inability to recognize once familiar settings and faces, a common symptom in individuals with Alzheimer's.
