Chapter 11 Cardiovascular Drugs Test Questions Quizlet Questions
Question 1 of 5
Which of the following glucocorticoids is an intermediate-acting drug?
Correct Answer: B
Rationale: The correct answer is B: Triamcinolone. Triamcinolone is an intermediate-acting glucocorticoid due to its duration of action, which typically lasts between 12 to 36 hours. Cortisone (A) is a short-acting glucocorticoid, with a duration of action of about 8-12 hours. Betamethasone (C) is a long-acting glucocorticoid, with a duration of action of around 36-54 hours. Choice D is incorrect as not all of the listed glucocorticoids are intermediate-acting.
Question 2 of 5
Deficiency symptom of vitamin A is:
Correct Answer: D
Rationale: The correct answer is D, "All of the above." Vitamin A deficiency can lead to various symptoms, including night blindness (choice A), xerophthalmia and keratomalacia (choice B), and various epithelial tissue defects that can result in decreased resistance to infective diseases, male and female infertility (choice C). These symptoms occur due to the role of vitamin A in maintaining healthy vision, skin, and mucous membranes. Therefore, choosing option D is correct as it encompasses all the possible deficiency symptoms associated with vitamin A deficiency.
Question 3 of 5
Hypertriglyceridemia denotes high blood levels of triglycerides. It has been associated with atherosclerosis, even in the absence of hypercholesterolemia (high cholesterol levels). This consideration is:
Correct Answer: A
Rationale: The correct answer is A: TRUE. Hypertriglyceridemia is indeed associated with atherosclerosis, even without high cholesterol levels. Triglycerides play a role in the development of atherosclerosis by contributing to the formation of plaque in the arteries. High levels of triglycerides can lead to inflammation and damage to the arterial walls, promoting the development of atherosclerosis. Therefore, the statement is true. Choices B, C, and D are incorrect because they do not accurately reflect the relationship between hypertriglyceridemia and atherosclerosis as described in the question stem.
Question 4 of 5
Which of the following drugs used in the treatment of gout has as its primary effect the reduction of uric acid synthesis:
Correct Answer: A
Rationale: Allopurinol is the correct answer as it inhibits xanthine oxidase, an enzyme involved in uric acid synthesis. By reducing the conversion of hypoxanthine to xanthine and xanthine to uric acid, allopurinol effectively lowers uric acid levels. Sulfinpyrazone increases uric acid excretion, not synthesis. Colchicine works by reducing inflammation in gout attacks, not affecting uric acid levels. Indomethacin is a nonsteroidal anti-inflammatory drug that alleviates gout symptoms but does not target uric acid synthesis.
Question 5 of 5
Indication for calcium administration is:
Correct Answer: B
Rationale: Step-by-step rationale: 1. Calcium administration is indicated in malabsorption of vitamin D because vitamin D is necessary for calcium absorption in the intestine. 2. Malabsorption of vitamin D leads to decreased calcium absorption, which can result in calcium deficiency. 3. Administering calcium can help compensate for the decreased absorption of calcium due to vitamin D malabsorption. Summary: - Option A is incorrect as the formation of vitamin D in the skin is not directly related to calcium administration. - Option C is incorrect as hypercalcemia of malignancy indicates excess calcium, not a need for calcium administration. - Option D is incorrect as it mentions the deficiency of vitamin D, not the malabsorption of vitamin D, which is the indication for calcium administration.
