What is the antidote for Warfarin?

Correct Answer: C

Rationale: The correct answer is C: Vitamin K. Warfarin is an anticoagulant that works by inhibiting vitamin K-dependent clotting factors. Therefore, the antidote for Warfarin is vitamin K, as it helps restore the clotting factors to their normal activity levels. Vitamin D (choice A), Vitamin C (choice B), and Vitamin B (choice D) do not have a direct role in counteracting the effects of Warfarin and are thus incorrect choices.

Correct Answer: A

Rationale: The correct answer is A: Laxative. Senna is classified as a laxative due to its mechanism of action in stimulating bowel movements. Senna contains compounds that act on the colon to increase fluid secretion and promote peristalsis, aiding in relieving constipation. Choices B, C, and D are incorrect. B: Anti-Ulcer drugs like proton pump inhibitors or H2 blockers are used to treat ulcers by reducing stomach acid production. C: ACE inhibitors are used to treat high blood pressure by blocking an enzyme that constricts blood vessels. D: Benzodiazepines are a class of drugs used to treat anxiety, insomnia, and seizures by enhancing the effects of the neurotransmitter GABA.

Correct Answer: B

Rationale: The correct answer is B: pre and post prandial advice. This section in MIMS provides guidance on how food can affect the absorption and efficacy of drugs. It includes recommendations on whether to take medication with or without food, which can impact drug effectiveness. Choice A, Preg. Cat, focuses on pregnancy category classification of drugs. Choice C, drug category, categorizes drugs based on their therapeutic class. Choice D, abbreviations, lists common medical abbreviations used in drug prescribing. Therefore, the correct answer B is the most relevant section for understanding the effect of food on drugs in MIMS.

Correct Answer: B

Rationale: The correct answer is B: mucilage. Mucilage refers to thick, viscid, adhesive liquids made by dispersing gum in water. Effervescent (A) means producing bubbles in a liquid, not related to gum dispersion. Spirits (C) are alcoholic beverages, unrelated to the given description. Collyria (D) are eye lotions, not related to the characteristics described. Therefore, B is the correct choice.

Correct Answer: D

Rationale: The correct answer is D: None of the above. Rationale: 1. Morphine is effective when given through various routes, not just subcutaneously. 2. The route of administration can affect the onset of action, with oral administration having a slower onset compared to intravenous. 3. Therefore, morphine is not only effective subcutaneously, can have varying effectiveness based on the route, and does not have a faster onset when administered orally. Summary: A is incorrect as morphine is effective through multiple routes. B is incorrect as the route of administration can impact effectiveness. C is incorrect as oral administration typically results in a slower onset of action.
