Correct Answer is A

Explanation

Choice A rationale

Omeprazole (Prilosec) is a proton pump inhibitor used to prevent peptic ulcers by reducing stomach acid production.

Choice B rationale

Omeprazole is used in combination with antibiotics to treat H. pylori-induced ulcers but not for acute treatment.

Choice C rationale

Omeprazole is not solely used to treat heartburn; it is mainly for preventing and treating peptic and gastric ulcers.

Choice D rationale

Omeprazole is used to prevent gastric ulcers caused by NSAIDs, but its primary indication is for peptic ulcers prevention. .

A. Prolonged QT interval. B. Constipation. C. Tachycardia. D. Hyperkalemia.

Correct Answer is A

Explanation

Choice A rationale

Azithromycin can prolong the QT interval, leading to potential cardiac arrhythmias. Patients with a history of prolonged QT interval or other heart conditions should be monitored closely.

Choice B rationale

Constipation is not commonly associated with azithromycin use. Gastrointestinal side effects may include diarrhea or nausea but not constipation.

Choice C rationale

While tachycardia can be a side effect of some medications, azithromycin is more commonly associated with QT prolongation rather than causing increased heart rate directly.

Choice D rationale

Hyperkalemia is not typically a concern with azithromycin. Electrolyte imbalances are not a common side effect of this antibiotic.
