Final answer:
The nurse should include instructions to resume tub baths after 24 hours when planning discharge teaching for a child who had a cardiac catheterization.
Step-by-step explanation:
When planning discharge teaching for the guardian of a child who had a cardiac catheterization, the nurse should include several instructions. One important instruction is to resume tub baths after 24 hours. This is because the child may have a dressing at the site of the catheter insertion, which needs time to heal. After 24 hours, it is usually safe to remove the dressing and allow the child to take tub baths.
However, it's important to note that if there are any signs of infection, such as redness, warmth, or discharge at the site, the guardian should contact the healthcare provider before resuming tub baths. In addition to this instruction, the nurse should also provide information on wound care, activity restrictions, and any medications that need to be administered at home.
