Rationale: The correct instruction that the nurse should include is to keep the child on bed rest for 12 hours following a cardiac catheterization. This is important to prevent bleeding at the insertion site and ensure proper healing. Allowing the child to bathe soon after the procedure, maintaining a pressure dressing for only 8 hours, or resuming regular activities the day after the procedure can increase the risk of complications such as bleeding or infection.

Rationale: Neuromaturational theory emphasizes that motor development progresses in a predictable sequence and rate, starting from primitive reflexes to voluntary control. It also states that low-level skills are foundational for higher-level skills. However, the theory does not support the idea that movement solely emerges from an interaction and cooperation of many systems, as it focuses more on the hierarchical development of motor skills.
