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.

Answer and Explanation

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.

Correct Answer is A

Explanation

A. Decrease osteoclastic activity: Osteoporosis treatments often focus on reducing osteoclastic activity, which is responsible for bone resorption, thereby helping to maintain or increase bone density.

B. Increase the kidneys' tubular secretion of calcium into the urine: This would decrease calcium levels in the body, which is not desired in osteoporosis treatment, as it would worsen bone density.

C. Increase resorption of calcium: Increasing bone resorption would exacerbate osteoporosis by weakening the bones further.

D. Suppress calcitonin: Calcitonin helps to inhibit bone resorption, so suppressing it would be counterproductive in treating osteoporosis.

A. percentage of glycosylated hemoglobin molecules that spill into the urine. B. percentage of glycosylated hemoglobin molecules carried by RBCs. C. effect of hypertension on RBCs over a long period of time. D. effect of insulin on the ability of hemoglobin to bond with glucose. E. effect of insulin on the ability of hemoglobin to bond with glucose.

Correct Answer is B

Explanation

A. His body does not produce any insulin so he must receive insulin injections: Type I diabetes is characterized by the destruction of pancreatic beta cells, resulting in little to no insulin production. Therefore, insulin must be administered via injection to replace the insulin the body cannot produce.

B. The pills are not as effective as the insulin injections: While this might be partially true for Type I diabetes, it is not the complete answer. Oral medications are generally not effective in Type I diabetes because they stimulate the pancreas to produce insulin, which is not possible in these patients.

C. He will only be on insulin injections for a short while, then he can take a pill: This is incorrect. Type I diabetes requires lifelong insulin therapy.

D. He can stop the insulin injections once his body begins to make insulin again: This is incorrect as Type I diabetes is a permanent condition where the body cannot produce insulin.
