A child has undergone a cardiac catheterization and is being prepared for discharge. The nurse is instructing the parents and child about postprocedure care. Which statements if made by the parents indicate the need for further teaching.

Choice A rationale The statement that the child needs to stay in bed for only 4–6 hours post-catheterization indicates the need for further teaching. For a venous approach, bed rest is typically required for 4–6 hours, but for an arterial approach, the standard period is 6–8 hours to allow adequate sealing of the vessel puncture site and minimize the risk of bleeding or hematoma formation. The nurse should confirm the specific approach and stress adherence to the minimum 6–8 hours for arterial entry to ensure vessel integrity is maintained. Choice B rationale The statement "I should apply pressure to the site in his groin if it starts to bleed" indicates an appropriate understanding of the required post-catheterization care and does not require further teaching. If bleeding occurs at the puncture site after discharge, the priority is to apply continuous, firm pressure immediately above the site to compress the vessel against the underlying bone, a crucial first-aid measure to control hemorrhage before seeking emergency medical help. Choice C rationale The statement that "A fever after the procedure is normal for a day or so" is incorrect and requires immediate correction. While a low-grade temperature elevation is possible in the first few hours due to the invasive nature of the procedure, a persistent or high fever is not normal and is often the earliest sign of infection, such as at the site or a systemic infection (sepsis). Parents should be instructed to report any fever (temperature ≥ 38.0°C or 100.4°F) immediately to their healthcare provider. Choice D rationale The statement "I can start his medications when we get home" indicates an appropriate understanding, assuming the child's regular medications were held temporarily for the procedure. Unless instructed otherwise by the cardiologist, the routine for most non-procedure-specific medications, such as maintenance drugs for heart failure or chronic conditions, is to resume them as scheduled once the child is stable and home to ensure continued management of their underlying cardiac condition. —.
