A client with diabetes mellitus visits a health care clinic. The client's diabetes previously had been well controlled with glyburide (Diabeta), 5 mg PO daily, but recently, the fasting blood glucose has been running 180-200 mg/dl. Which medication, if added to the clients regimen, may have contributed to the hyperglycemia?

phenelzine (Nardil)

allopurinol (Zyloprim)

Metoprolol (Lopressor)

Methylprednisolone (Medrol pack)

Answer and Explanation

The Correct Answer is D

Choice A rationale: Phenelzine is an antidepressant that typically does not affect blood glucose levels significantly.

Choice B rationale: Allopurinol, used for gout, is not known to significantly impact blood glucose levels.

Choice C rationale: Metoprolol, a beta-blocker, might mask some symptoms of hypoglycemia but is not typically associated with causing hyperglycemia.

Choice D rationale: Methylprednisolone, a corticosteroid, can elevate blood glucose levels and might contribute to hyperglycemia in a person with diabetes mellitus.

Correct Answer is B

Explanation

Choice A rationale: Anterior spinal artery syndrome is caused by ischemia of the anterior two-thirds of the spinal cord, resulting in loss of motor function and pain and temperature sensation below the level of the lesion.

Choice B rationale: This is a condition that occurs when the nerve roots in the lower end of the spinal cord are compressed, causing symptoms such as lower back pain, sciatica, saddle anesthesia, bladder and bowel dysfunction, and sexual dysfunction.

Choice C rationale: Horner's syndrome is caused by damage to the sympathetic nerve fibers in the neck or chest, resulting in drooping eyelid, constricted pupil, and lack of sweating on one side of the face.

Choice D rationale: Brown-Séquard syndrome is caused by hemisection of the spinal cord, resulting in ipsilateral loss of motor function and proprioception and contralateral loss of pain and temperature sensation below the level of the lesion.

A. Increases insulin release from the pancreas, inhibits glucagon secretion, and decreases gastric emptying. B. Reduces glucose production by the liver and enhances insulin sensitivity. C. Slows the absorption of carbohydrate in the small intestine. D. Increases insulin production from the pancreas.

Correct Answer is B

Explanation

Choice A rationale: Metformin does not significantly affect insulin release from the pancreas or glucagon secretion but reduces glucose production by the liver and enhances insulin sensitivity in tissues.

Choice B rationale: Metformin primarily works by reducing glucose production in the liver and improving the body's response to insulin, thereby lowering blood sugar levels.

Choice C rationale: Metformin does not notably slow carbohydrate absorption in the small intestine.

Choice D rationale: Metformin does not directly increase insulin production from the pancreas.
