Drugs for Cardiovascular Disease Questions
Question 1 of 5
The indication for interferon alpha administration is:
Correct Answer: D
Rationale: Rationale: Interferon alpha is indicated for treating viral infections and certain cancers, making it suitable for Hepatitis C, Kaposi's sarcoma, and Condyloma acuminatum. Therefore, the correct answer is D. Choice A is correct as interferon alpha is used in Hepatitis C treatment. Choice B is also correct as it is used in treating Kaposi's sarcoma. Choice C is correct as it is used in treating Condyloma acuminatum. Therefore, choosing all of the above (D) is the correct answer as interferon alpha is indicated for all these conditions.
Question 2 of 5
Effects of drugs in lowering blood cholesterol levels are additive with those of diet. This consideration is:
Correct Answer: A
Rationale: Correct Answer: A (TRUE) Rationale: 1. Drugs and diet independently lower blood cholesterol levels. 2. When used together, their effects are additive, leading to a greater reduction. 3. This synergy implies that the statement is true. 4. Other options (B, C, D) are incorrect as they do not acknowledge the additive nature of combining drugs and diet interventions.
Question 3 of 5
The unwanted effect of cholecalciferol is:
Correct Answer: D
Rationale: The correct answer is D: Metastatic calcifications. Cholecalciferol, a form of vitamin D, can lead to excessive calcium levels in the blood, causing calcium deposits in soft tissues like the kidneys, lungs, and blood vessels. This can result in metastatic calcifications. Choice A is incorrect as cholecalciferol deficiency, not excess, leads to defective bone mineralization. Choice B is unrelated to cholecalciferol effects. Choice C is not a common side effect of cholecalciferol supplementation.
Question 4 of 5
The drug can promote sodium loss in patients with low (e.g., 40 ml/min) glomerular filtration rates:
Correct Answer: A
Rationale: The correct answer is A: Furosemide (Lasix). Furosemide is a loop diuretic that acts on the ascending loop of Henle to inhibit sodium reabsorption, leading to sodium loss. In patients with low glomerular filtration rates, furosemide can still promote sodium loss by directly affecting renal tubular function. Acetazolamide, on the other hand, is a carbonic anhydrase inhibitor that primarily works in the proximal tubule and is not as effective in promoting sodium loss in patients with low GFR. Therefore, the correct choice is A as furosemide can promote sodium loss in patients with low GFR, while acetazolamide is not as effective in this scenario.
Question 5 of 5
Antibiotics inhibiting the bacterial cell wall synthesis are:
Correct Answer: A
Rationale: The correct answer is A: Beta-lactam antibiotics. These antibiotics work by inhibiting the synthesis of bacterial cell walls through binding to penicillin-binding proteins, leading to cell lysis. Tetracyclines (B) inhibit protein synthesis, aminoglycosides (C) disrupt protein synthesis by binding to ribosomes, and macrolides (D) interfere with protein synthesis by binding to the 50S ribosomal subunit. Therefore, only beta-lactam antibiotics directly target bacterial cell wall synthesis, making them the correct choice.
