- A. Inflammation
- B. Asthma
- C. Addison's disease
- D. Wilson's disease
Correct Answer: D
Rationale: Explanation: Dexamethasone is a corticosteroid used to treat inflammation and conditions like asthma and Addison's disease, which involve inflammation or immune responses. Wilson's disease is a genetic disorder related to copper metabolism, not treated with Dexamethasone. Dexamethasone could worsen Wilson's disease due to its potential impact on copper levels.

Which of the following is the primary site of activity for the drug Warfarin?
- A. Kidney
- B. Liver
- C. Blood
- D. Heart
Correct Answer: B
Rationale: The correct answer is B: Liver. Warfarin is primarily metabolized in the liver by the cytochrome P450 enzyme system. The liver is responsible for breaking down and activating many drugs, including Warfarin. It is where the drug's metabolism and effects are most significant. The other choices are incorrect because Warfarin's main site of activity is in the liver, not the kidney, blood, or heart. The kidney mainly excretes the drug, while the blood carries it throughout the body, and the heart is not directly involved in Warfarin's metabolism.
Which of the following is not a side effect of the cholinoreceptor blocker (Atropine)?
- A. Increased pulse
- B. Diarrhea
- C. Constipation
- D. Mydriasis
Correct Answer: B
Rationale: The correct answer is B: Diarrhea. Atropine, a cholinoreceptor blocker, inhibits acetylcholine, causing decreased GI motility leading to constipation. Atropine also increases pulse rate due to reduced vagal tone (A). It causes mydriasis by blocking cholinergic receptors in the eye (D). Diarrhea is not a typical side effect of atropine due to its anticholinergic properties.
Which of the following is not a side effect of Sympathoplegics (Clonidine)?
- A. Hypertension
- B. Difficulty breathing
- C. Dry oral cavity
- D. Lethargic behavior
Correct Answer: A
Rationale: The correct answer is A: Hypertension is not a side effect of Sympathoplegics (Clonidine). Sympathoplegics are medications that inhibit the sympathetic nervous system, leading to decreased heart rate and blood pressure. Therefore, hypertension is not a common side effect. Choices B, C, and D are incorrect because difficulty breathing, dry oral cavity, and lethargic behavior are potential side effects of Sympathoplegics due to their central nervous system depressant effects.
A drug ending in the suffix (pril) is considered a ______.
- A. H
- B. ACE inhibitor
- C. Antifungal
- D. Beta agonist
Correct Answer: B
Rationale: The correct answer is B: ACE inhibitor. Drugs ending in the suffix (-pril) typically refer to ACE inhibitors, which are commonly used to treat hypertension and heart failure by inhibiting the angiotensin-converting enzyme. ACE inhibitors do not belong to the categories mentioned in the other choices. Choice A (H) is vague and does not provide any relevant information. Choice C (Antifungal) is incorrect as drugs ending in (-pril) are not typically used to treat fungal infections. Choice D (Beta agonist) is also incorrect as drugs ending in (-pril) do not belong to the class of beta agonists, which are used to treat conditions like asthma and COPD.
Which of the following conditions is not treated with Nifedipine?
- A. Angina
- B. Arrhythmias
- C. Hypertension
- D. Fluid retention
Correct Answer: D
Rationale: Nifedipine is a calcium channel blocker primarily used to treat angina, arrhythmias, and hypertension due to its vasodilatory effect. However, it does not treat fluid retention as it does not have diuretic properties. Therefore, the correct answer is D. Choice A, B, and C are incorrect because nifedipine is commonly used to manage these conditions.
