A patient presents to the emergency department (ED) with a two-hour history of hemiparesis of the right arm and leg. Also, it is noted during assessment (examination) that the left side of her face moves normally, but the other side droops. Identify the item which helps to explain the connection between the pathophysiology of this illness and the pattern of signs and symptoms (555)
Ischemia of the brain tissue is causing cellular injury, swelling and malfunction of the contralateral side
The functioning of the right cranial nerve controlling facial movement is compromised by cerebral edema
The sensorimotor tracts leading from the brain to the body decussate and control the arm and leg on the same side as the lesion,
The corticospinal tracts leading from the brain to the body decussate and control the ipsilateral arm and leg.
The Correct Answer is A
A. Ischemia of the brain tissue is causing cellular injury, swelling, and malfunction of the contralateral side: Hemiparesis occurs on the side opposite to the brain lesion due to the crossing (decussation) of motor pathways.
B. The functioning of the right cranial nerve controlling facial movement is compromised by cerebral edema: While facial nerve involvement can cause drooping, the hemiparesis suggests a central (brain) rather than peripheral issue.
C. The sensorimotor tracts leading from the brain to the body decussate and control the arm and leg on the same side as the lesion: This is incorrect because the tracts control the contralateral side of the body.
D. The corticospinal tracts leading from the brain to the body decussate and control the ipsilateral arm and leg: This is incorrect; the corticospinal tracts control the contralateral side.

Explanation
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. Tetany of the hands with a positive Chvostek sign: Tetany and a positive Chvostek sign are more associated with hypocalcemia rather than Hashimoto's thyroiditis.
B. Polyuria, sweating, and dry mucous membranes: These symptoms are more indicative of hyperthyroidism or diabetes rather than hypothyroidism, which is characteristic of Hashimoto's thyroiditis.
C. Forgetfulness, depression, and anemia: Hashimoto's thyroiditis, which causes hypothyroidism, can lead to symptoms like forgetfulness, depression, and anemia due to reduced thyroid hormone levels.
D. Nervousness, irritability, and diarrhea: These symptoms are associated with hyperthyroidism rather than hypothyroidism.
