Step-by-step explanation:
The rationale for the interdisciplinary team meeting with the client's parents in the pediatric intensive care unit (PICU) is to share and evaluate information for care planning and implementation. This meeting allows the different health professionals involved in the client's care to come together, discuss the client's condition, and develop a comprehensive care plan while preventing priority conflicts, redundancy, and omissions in care. It is important to involve the parents in these discussions so they can be informed and involved in the decision-making process.
