Final answer:
The correct instruction for the parents of an infant postoperative following hypospadias repair with a stent placement is to apply direct pressure if bleeding occurs at the surgical site.
Step-by-step explanation:
The question pertains to postoperative care instructions for an infant following hypospadias repair with stent placement. Among the given options, the correct instruction for the parents should be B) Apply direct pressure if bleeding occurs at the surgical site. This is because postoperative bleeding is a potential complication, and applying direct pressure can help to control it. Removing the stent (option A) during diaper changes should not be done unless instructed by the surgeon, as the stent is placed to ensure proper healing and drainage. Option C, avoiding giving the infant pain medication, is incorrect because pain management is important after surgery. Option D, limiting fluid intake, is also not recommended as proper hydration is essential for healing and to prevent blockage of the stent.
