Correct Answer: B

Rationale: Cinchonism is associated with Quinidine, not Valproic acid, Isoniazid, or Ethosuximide. Cinchonism is characterized by symptoms such as tinnitus, dizziness, and headaches. Quinidine, being an antiarrhythmic agent, can lead to this condition as a side effect.

Correct Answer: A

Rationale: Ephedrine is not typically used to treat COPD. While it can help relieve symptoms like congestion and hypotension, it is not a first-line treatment for COPD. Incontinence is not a condition commonly treated with Ephedrine either.

Correct Answer: C

Rationale: Lansoprazole is a proton pump inhibitor used to treat conditions related to excessive stomach acid production, such as Zollinger-Ellison syndrome, gastritis, and reflux. However, it is not indicated for the treatment of hypertension, which is managed using antihypertensive medications. Therefore, the correct answer is C: Hypertension.

Correct Answer: D

Rationale: Nifedipine is a calcium channel blocker primarily used in the management of angina and hypertension. It is not typically used to treat arrhythmias or fluid retention. Angina is chest pain caused by reduced blood flow to the heart, and hypertension is high blood pressure. Therefore, fluid retention is the condition that is not treated with Nifedipine.

Correct Answer: D

Rationale: Midazolam is a benzodiazepine commonly used for its sedative, anxiolytic, and amnestic effects. While dizziness can be a side effect of Midazolam, it is not a primary or common effect. Therefore, the correct answer is D, as it deviates from the typical effects associated with Midazolam.
