Chapter 11 Cardiovascular Drugs Test Questions Quizlet Questions
Question 1 of 5
Indicate the nootropic agent useful in disorders of brain circulation:
Correct Answer: B
Rationale: The correct answer is B: Pyracetam. Pyracetam is a nootropic agent that is known for its benefits in enhancing cognitive function and improving brain circulation. It works by increasing blood flow and oxygen utilization in the brain, making it useful in disorders of brain circulation. A: Aspirin is a common pain reliever and anti-inflammatory drug, but it is not specifically classified as a nootropic agent for brain circulation disorders. C: Warfarin is an anticoagulant medication that helps prevent blood clots, but it is not a typical choice for enhancing brain circulation or cognitive function. D: "All the above" is incorrect as only Pyracetam is specifically known for its benefits in disorders of brain circulation, making it the correct choice in this scenario.
Question 2 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 3 of 5
These histamine H1 antagonists are recognized for as second-generation antihistamines, EXCEPT:
Correct Answer: D
Rationale: The correct answer is D, Suprastine, because it is not a second-generation antihistamine. Second-generation antihistamines are known for having minimal sedative effects and longer duration of action compared to first-generation antihistamines. Astemizole, Loratadine, and Cetirizine are all second-generation antihistamines with these characteristics. Suprastine, on the other hand, is a first-generation antihistamine and does not meet the criteria for being a second-generation antihistamine. Therefore, it is the exception in this list.
Question 4 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 5 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.
