A nurse manager in the pediatric intensive care unit understands that when providing information to parents of a critically ill child, the following should be performed FIRST:

The correct answer is A: assessing the parents' preferences regarding the amount of information provided. It is crucial to prioritize understanding the parents' preferences first, as this helps establish effective communication and build trust. By assessing their preferences, the nurse manager can tailor the information delivery to meet the parents' needs and emotional readiness. This approach fosters a supportive environment and ensures that information is provided in a manner that is most helpful to the family during a highly stressful time.

Choices B, C, and D are incorrect because they focus on providing information without considering the individual needs and preferences of the parents. Arranging for a specialist, directing to online resources, or making brochures available can be beneficial, but they should come after assessing the parents' preferences to ensure the information is received and understood effectively.
