A nurse is caring for a client who is experiencing preterm labor and has a new prescription for terbutaline.Which of the following findings is a contraindication for administration of this medication?

Choice A rationaleTerbutaline is contraindicated in heart disease because it can cause tachycardia and arrhythmias, worsening cardiac conditions. Cardiovascular side effects result from its beta-adrenergic agonist action.Choice B rationaleCervical dilation of 2 cm is not a contraindication for terbutaline. The medication can be used to delay labor regardless of early cervical changes.Choice C rationaleGestational age of 34 weeks is not a contraindication. Terbutaline can be administered to halt preterm labor at this gestational stage if needed.Choice D rationaleAllergy to penicillin does not contraindicate terbutaline use, as the medication belongs to a different pharmacological class and lacks cross-reactivity with penicillins.
