is an inherited disorder that, most often, begins before the age of fifty

causes unusual sensory sensations such as numbness and shooting pain (paresthesia)
The Correct Answer is A
A. Manifests as neurofibrillary tangles and amyloid plaques that cause a disruption of brain impulses: Alzheimer's disease is characterized by the accumulation of amyloid plaques and neurofibrillary tangles in the brain, leading to disrupted neural communication.
B. Is an inherited disorder that, most often, begins before the age of fifty: While there are inherited forms of Alzheimer's (early-onset), most cases are sporadic and occur after age 65.
C. Can be caused by increased cerebral levels of acetylcholine: Alzheimer's disease is associated with decreased levels of acetylcholine, not increased levels.
D. Causes unusual sensory sensations such as numbness and shooting pain (paresthesia): Paresthesia is not a typical symptom of Alzheimer's disease; it is more related to neurological or peripheral nerve disorders.

Correct Answer is C
Explanation
A. Administer some insulin: Insulin is not appropriate unless there is evidence of hyperglycemia, which is not suggested by the symptoms described.
B. Prepare the patient to receive a blood transfusion: The symptoms described are not indicative of a need for a blood transfusion but rather suggest adrenal insufficiency.
C. Administer IV glucose: Addisonian crisis can be triggered by stress and dehydration, leading to low blood sugar and symptoms such as weakness and confusion. Administering IV glucose can help manage hypoglycemia and provide immediate support.

Explanation
A. The patient is now sleepy and won't wake up: Increased drowsiness or difficulty waking up could indicate worsening of the hemorrhagic stroke, potentially due to increased intracranial pressure or a secondary brain injury.
B. Identification of an elevated serum cholesterol level: Elevated cholesterol is a risk factor for ischemic strokes but is not a direct indicator of complications from a hemorrhagic stroke.
C. The presence of nausea and a headache: This could be a common symptom following a hemorrhagic stroke but is not necessarily a specific indicator of a complication.
D. A complaint of neck pain and light intolerance: These symptoms are less specific to complications of a hemorrhagic stroke and could be related to other issues.
