Correct Answer is A
Explanation
Choice A rationale
A receptor antagonist blocks the effects of normal cellular functions by binding to receptor sites and preventing endogenous substances (like hormones or neurotransmitters) from activating those receptors.
Choice B rationale
Receptor antagonists do not accelerate hormones attaching to cell receptor sites; they prevent this process by blocking the receptors.
Choice C rationale
Receptor antagonists do not minimize the risk of other medications becoming toxic. They specifically block the action of certain endogenous substances.
Choice D rationale
Receptor antagonists do not increase the action of cells; rather, they inhibit or block the usual effects.
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.
