Tick the drug – a derivative of Ergot:

Correct Answer: A

Rationale: Nicergoline is the correct answer as it is a derivative of Ergot. Ergot alkaloids are compounds derived from the ergot fungus and Nicergoline falls under this category. Warfarin is a blood thinner, Cinnarizine is a calcium channel blocker, and Vinpocetine is a nootropic drug. These drugs are not derivatives of Ergot, making them incorrect choices.

Correct Answer: A

Rationale: Prednisolone is the correct answer because it is a short- to medium-acting glucocorticoid, with a duration of action of about 12-36 hours. Dexamethasone is a long-acting glucocorticoid, with a duration of action of 36-72 hours. Triamcinolone is also a long-acting glucocorticoid with a duration of action of 12-36 hours. Therefore, choices B and C are incorrect. Choice D is incorrect because not all of the options are short- to medium-acting drugs.

Correct Answer: B

Rationale: The correct answer is B: Piperidines; i.e. Loratadine, Fexofenadine. Second-generation antihistamines like Loratadine and Fexofenadine belong to the piperidine category. Second-generation antihistamines are preferred over first-generation due to their lower sedative effects and longer duration of action. Alkylamines (A), Ethylenediamines (C), and Phenothiazines (D) are not classified as second-generation antihistamines and are associated with more sedation and anticholinergic side effects.

Correct Answer: D

Rationale: The correct answer is D because vitamin A does not act as a hormone involved in the regulation of calcium and phosphorus homeostasis. A: This statement is true as vitamin A is essential for the transmission of light stimuli to the brain through the formation of visual pigment in the retina. B: This statement is true as retinoic acid, a metabolite of vitamin A, plays a crucial role in regulating cell growth and differentiation in various tissues. C: This statement is true as retinoic acid is important during embryogenesis for proper development. In summary, vitamin A is not involved in the regulation of calcium and phosphorus homeostasis, making statement D the correct answer.

Correct Answer: A

Rationale: The correct answer is A: TRUE. Hyperlipoproteinemia is indeed a condition characterized by elevated levels of lipoproteins in the blood. Lipoproteins carry cholesterol and other fats through the bloodstream. The high levels of lipoproteins in hyperlipoproteinemia can increase the risk of cardiovascular diseases. Explanation of other choices: B: FALSE - This is incorrect because hyperlipoproteinemia is a real medical condition. C: All - This is incorrect as it doesn't accurately reflect the specific nature of hyperlipoproteinemia. D: None - This is incorrect as hyperlipoproteinemia is a recognized medical condition with specific diagnostic criteria.
