Women taking probucol (Lorelco) should wait for 6 months after cessation of therapy before becoming pregnant. This consideration is:

Correct Answer: A

Rationale: The correct answer is A: TRUE. Probufol can stay in the body for a long time, and waiting 6 months after stopping the medication before becoming pregnant is crucial to prevent potential harm to the fetus. This waiting period allows the drug to be eliminated from the body, reducing the risk of any adverse effects on the pregnancy. Choice B (FALSE) is incorrect because it is important for women to wait before becoming pregnant after stopping probucol therapy. Choices C (All) and D (None) are also incorrect as they do not accurately represent the specific guideline related to probucol use and pregnancy.

Correct Answer: A

Rationale: The correct answer is A: 350-400 mg. The recommended daily allowance of magnesium for adults is typically around 350-400 mg. This amount is based on the average dietary intake needed to maintain optimal health and bodily functions. Magnesium plays a crucial role in various physiological processes such as muscle and nerve function, blood sugar regulation, and bone health. Choice B (6-9 g) is too high for daily magnesium intake and could lead to toxicity symptoms. Choice C (25 g) is also excessively high and can cause serious health issues. Choice D (1.5-4 mg) is too low and would not meet the body's daily magnesium requirements. Therefore, the correct answer is A as it falls within the recommended range for daily magnesium intake to support overall well-being.

Correct Answer: A

Rationale: The correct answer is A: Furosemide (Lasix). Furosemide is a loop diuretic that competitively blocks chloride channels in the ascending loop of Henle, preventing the reabsorption of sodium, potassium, and chloride in the renal tubules. This mechanism leads to increased excretion of these ions and water, resulting in diuresis. Acetazolamide (B) inhibits carbonic anhydrase, Triamterene (C) blocks sodium channels, and Mannitol (D) is an osmotic diuretic. Therefore, these choices do not competitively block chloride channels like Furosemide does in the renal tubular cells.

Correct Answer: C

Rationale: The correct answer is C: Myconazol. Myconazol is not an antibiotic; it is an antifungal drug that belongs to the class of azole antifungals. Antibiotics target bacteria, while antifungal drugs target fungi. Amphotericin B, Nystatin, and Griseofulvin are antifungal drugs that are also considered antibiotics because they inhibit the growth of fungi by various mechanisms. Amphotericin B disrupts fungal cell membrane function, Nystatin binds to ergosterol in fungal cell membranes, and Griseofulvin interferes with fungal cell division. Therefore, Myconazol is the correct answer as it does not belong to the antibiotic class.

Correct Answer: C

Rationale: Step-by-step rationale for choice C: 1. Sodium stibogluconate is a first-line treatment for leishmaniasis. 2. It is an antimonial compound effective against Leishmania parasites. 3. It is administered intravenously for visceral leishmaniasis. 4. Has been used for decades with proven efficacy. Summary of other choices: A: Pyrimethamine - used for malaria, not leishmaniasis. B: Albendazole - used for helminthic infections, not leishmaniasis. D: Tinidazole - used for protozoal infections like Giardiasis, not leishmaniasis.
