Final answer:
The nurse would question the prescription for mydriatic eye drops.
Step-by-step explanation:
If a nurse is reviewing the preoperative prescriptions of a client scheduled for a keratoplasty, one prescription that the nurse would question is Mydriatic eye drops. Mydriatic eye drops are used to dilate the pupil, which can increase intraocular pressure and may not be ideal for a client undergoing a keratoplasty. The dilation of the pupil can also interfere with proper assessment of the eye during the surgery. Therefore, the nurse would want to clarify or discuss this prescription with the healthcare provider.
