The nurse is caring for a patient who is prescribed azithromycin for a respiratory infection.
The nurse should assess the patient's medical history for any past or current conditions related to:
Prolonged QT interval.
Constipation.
Tachycardia.
Hyperkalemia.
The Correct Answer is A
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.
