Physiologic doses of glucocorticoid can result in:

Correct Answer: D

Rationale: The correct answer is D because physiologic doses of glucocorticoids can indeed result in all of the mentioned effects. A: Glucocorticoids can increase liver glycogen stores, gluconeogenesis, and lipolysis. B: Glucocorticoids help maintain cardiovascular function by potentiating norepinephrine and improve skeletal muscle function. C: Glucocorticoids can enhance hemoglobin synthesis, leading to an increase in red blood cell count. Therefore, all three choices are valid effects of physiologic doses of glucocorticoids, making option D the correct answer.

Correct Answer: D

Rationale: The correct answer is D (All of the above) because riboflavin deficiency can manifest as all the symptoms mentioned in choices A, B, and C. Riboflavin is essential for maintaining healthy skin and mucous membranes, so deficiency can lead to cheilitis (choice A) and cheilosis (choice B), which both involve inflammation and fissures in the lips. Additionally, riboflavin deficiency can cause angular stomatitis (choice C), which is characterized by inflammation and fissures at the corners of the mouth. Therefore, all the symptoms listed in choices A, B, and C are potential deficiency symptoms of riboflavin. Choices A, B, and C are incorrect individually because they only describe specific symptoms of riboflavin deficiency, whereas the correct answer D encompasses all the possible symptoms.

Correct Answer: D

Rationale: The correct answer is D because chylomicron is a large lipoprotein particle produced in the small intestine absorbing dietary fats. This lipoprotein transports lipids to adipose tissue where they are broken down by lipoprotein lipase. The other choices are incorrect because: A: Chylomicron does not contain small amounts of cholesterol and triglycerides, nor is it associated with decreased risk of atherosclerosis. B: Chylomicron carries dietary lipids, not cholesterol from the liver to tissues. C: Chylomicron does not contain high amounts of cholesterol and is not associated with increased risk of atherosclerosis.

Correct Answer: C

Rationale: The correct answer is C: Colchicine. Uricosuric drugs increase excretion of uric acid in the urine to treat gout. Colchicine is not a uricosuric drug; it is used to treat gout flares by reducing inflammation. Probenecid and Sulfinpyrazone are uricosuric drugs that work by inhibiting uric acid reabsorption in the kidneys. Aspirin at high dosages can compete with uric acid for excretion in the kidneys, so it can also have uricosuric effects.

Correct Answer: C

Rationale: Rationale: C. Renal failure and malabsorption are not major causes of hypercalcemia. - Hyperparathyroidism leads to increased calcium levels due to overproduction of PTH. - Cancer with or without bone metastases can release calcium into the bloodstream. - Hypervitaminosis D can cause hypercalcemia by increasing intestinal calcium absorption. Renal failure and malabsorption do not directly increase calcium levels.
