A nurse administered ondansetron (Zofran) IV to a client one hour ago.Which of the following findings should the nurse recognize as a complication of this medication?

Bradycardia.

Absence of nausea.

Shortened QT interval.

Prolonged QT interval.

Answer and Explanation

The Correct Answer is D

Choice A rationale

Bradycardia is not a common complication of ondansetron (Zofran). Instead, one should watch for changes in heart rhythm such as QT interval prolongation.

Choice B rationale

Absence of nausea indicates the desired effect of ondansetron, not a complication.

Choice C rationale

Ondansetron is associated with prolongation of the QT interval, not shortening. QT interval shortening is not a recognized complication.

Choice D rationale

Prolonged QT interval is a known complication of ondansetron and can increase the risk of life-threatening arrhythmias. .
