José is a 4-year-old child scheduled for a cardiac catheterization. What should be included in preoperative teaching?
- A. Directed at his parents because he is too young to understand
- B. Detailed in regard to the actual procedures so he will know what to expect
- C. Done several days before the procedure so that he will be prepared
- D. Adapted to his level of development so that he can understand
Correct Answer: D
Rationale: Preoperative teaching should always be directed at the child’s stage of development. The caregivers also benefit from the same explanations.

Preschoolers will not understand in-depth descriptions and should be prepared close to the time of the cardiac catheterization.
