Chapter 11 Cardiovascular Drugs Test Questions Quizlet Questions
Question 1 of 5
Insulin can not be administered by:
Correct Answer: A
Rationale: The correct answer is A: Oral route. Insulin cannot be administered orally because it gets degraded by stomach enzymes. The correct routes for insulin administration are B: Intravenous route, C: Subcutaneous route, and D: Intramuscular route. These routes allow for direct absorption into the bloodstream without degradation. Intravenous route ensures rapid onset, subcutaneous route is commonly used for self-administration, and intramuscular route provides slower absorption.
Question 2 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 3 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 4 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 5 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.
