A nurse is providing discharge instructions to the parent of a 10-year-old child following a cardiac catheterization. Which of the following instructions should the nurse include?

A. Acetaminophen is appropriate for managing mild discomfort post-procedure. B. Tub baths are generally avoided for the first few days to prevent infection at the catheterization site; sponge baths are preferred. C. Keeping the child home for 1 week might be excessive; follow the healthcare provider's specific instructions regarding activity and school return. D. Clear liquids are typically offered as tolerated, but the primary concern post-procedure is monitoring the insertion site and ensuring the child rests adequately.
