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.
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. .
