Question 1 of 5
Which of the following glucocorticoids have one fluoride atom in its chemical structure?
Correct Answer: B
Rationale: The correct answer is B: Fluocinolone. This glucocorticoid has one fluoride atom in its chemical structure, making it the only option that fits the criteria. Prednisolone (A) does not contain any fluoride atoms. Triamcinolone (C) also does not have a fluoride atom. Option D is incorrect because only Fluocinolone (B) has the specific chemical structure with one fluoride atom. Thus, B is the correct answer.
Question 2 of 5
Keratomalacia is:
Correct Answer: B
Rationale: The correct answer is B because keratomalacia is specifically defined as softening and subsequent ulceration and perforation of the cornea due to severe vitamin A deficiency. Choice A is incorrect as it describes xerophthalmia, not keratomalacia. Choice C describes photophobia, not keratomalacia. Choice D is incorrect as it includes all the options, but only choice B accurately defines keratomalacia.
Question 3 of 5
Which of the following consideration about type I familial hyperlipoproteinemia is True:
Correct Answer: A
Rationale: Rationale: 1. Type I familial hyperlipoproteinemia is characterized by increased chylomicrons and triglycerides in the serum, which decrease with a fat-free diet. 2. High- and low-density lipoproteins decrease with a fat-free diet, contrary to other types of hyperlipoproteinemia. 3. Tissue lipoprotein lipase activity is decreased in type I familial hyperlipoproteinemia. 4. Other choices are incorrect because they do not accurately describe the characteristics and pathophysiology of type I familial hyperlipoproteinemia. Summary: Choice A is correct as it aligns with the hallmark features of type I familial hyperlipoproteinemia. Choices B, C, and D contain inaccuracies regarding the lipid profile, genetic basis, and response to dietary changes in this condition.
Question 4 of 5
Action of the parathyroid hormone is:
Correct Answer: D
Rationale: The correct answer is D because the parathyroid hormone (PTH) has multiple functions in the body. A: PTH increases calcium and phosphate absorption in the intestine by stimulating the production of active vitamin D. B: PTH decreases calcium excretion and increases phosphate excretion in the kidneys, helping to maintain serum calcium levels. C: In bone, PTH increases calcium and phosphate resorption at high doses and may increase bone formation at low doses. Therefore, all of the above statements are true, making D the correct choice.
Question 5 of 5
Which of the oral calcium preparations is often the preparation of choice:
Correct Answer: A
Rationale: The correct answer is A: Calcium carbonate. It is often the preparation of choice due to its high calcium content (40%). This means that a smaller dose can provide the required amount of elemental calcium compared to other options. Additionally, calcium carbonate is well-absorbed in an acidic environment, making it suitable for individuals with normal gastric acid production. Incorrect choices: B: Calcium lactate has a lower calcium content (13%) compared to calcium carbonate, requiring a higher dose to achieve the same calcium intake. C: Calcium phosphate has a lower calcium content (25%) compared to calcium carbonate, making it less efficient in providing elemental calcium. D: Calcium citrate has a lower calcium content (17%) compared to calcium carbonate and is better absorbed in individuals with low gastric acid production. However, in general, calcium carbonate is preferred for its higher calcium content and cost-effectiveness.
