Which of the following drugs is associated with the reaction of Cinchonism?
- A. Valproic acid
- B. Quinidine
- C. Isoniazid
- D. Ethosuximide
Correct Answer: B
Rationale: The correct answer is B: Quinidine. Cinchonism is a condition caused by the toxicity of Cinchona alkaloids, which are found in drugs like quinine and quinidine. Quinidine is specifically known to cause symptoms of cinchonism such as tinnitus, headache, blurred vision, and nausea. Valproic acid (choice A) is an anticonvulsant, not associated with cinchonism. Isoniazid (choice C) is an antibiotic used to treat tuberculosis and does not cause cinchonism. Ethosuximide (choice D) is an anticonvulsant used to treat absence seizures and is not linked to cinchonism.

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.
Which of the following conditions is not treated with Lansoprazole?
- A. Zollinger-Ellison syndrome
- B. Gastritis
- C. Hypertension
- D. Reflux
Correct Answer: C
Rationale: Rationale: Lansoprazole is a proton pump inhibitor used to reduce stomach acid production. Hypertension is a condition related to high blood pressure and is not treated with Lansoprazole. Zollinger-Ellison syndrome, gastritis, and reflux are all conditions that can be treated with Lansoprazole due to its ability to reduce stomach acid. Therefore, choice C is the correct answer.
A drug ending in the suffix (tidine) is considered a ______.
- A. Antidepressant
- B. Protease inhibitor
- C. Beta antagonist
- D. H antagonist
Correct Answer: D
Rationale: The correct answer is D: H antagonist. Drugs ending in the suffix (tidine) typically belong to the class of histamine H2-receptor antagonists. These drugs work by blocking the action of histamine on H2 receptors in the stomach, reducing the production of stomach acid. This is commonly used to treat conditions such as peptic ulcers and gastroesophageal reflux disease.
Explanation of other choices:
A: Antidepressant - Drugs ending in (pramine) or (ine) are more commonly associated with antidepressants.
B: Protease inhibitor - Drugs ending in (navir) are typically protease inhibitors used in antiviral therapy.
C: Beta antagonist - Drugs ending in (olol) are beta-blockers, which are used to treat conditions such as hypertension and heart disease, not related to (tidine) suffix.
Which of the following is not a side effect associated with Prednisone toxicity?
- A. Cataracts
- B. Hypotension
- C. Psychosis
- D. Acne
Correct Answer: B
Rationale: The correct answer is B: Hypotension. Prednisone toxicity typically causes hypertension, not hypotension. Prednisone can lead to increased blood pressure due to its sodium-retaining effects. Cataracts (A), Psychosis (C), and Acne (D) are all known side effects of Prednisone toxicity. Cataracts can form due to long-term steroid use, psychosis can occur especially at higher doses, and acne is a common skin side effect. Therefore, hypotension is the odd one out among the choices given.
Which of the following is not a side effect of the ACE Inhibitor (Captopril)?
- A. Rash
- B. Angioedema
- C. Cough
- D. Congestion
Correct Answer: D
Rationale: The correct answer is D: Congestion. ACE Inhibitors like Captopril do not typically cause congestion as a side effect. The main reason is that ACE inhibitors work by dilating blood vessels, which helps reduce blood pressure and improve blood flow. Congestion is more commonly associated with conditions like allergies or upper respiratory infections.
A: Rash - Possible side effect of ACE inhibitors, but not specific to Captopril.
B: Angioedema - Rare but serious side effect of ACE inhibitors, including Captopril.
C: Cough - Common side effect of ACE inhibitors due to increased bradykinin levels.
