Step-by-step explanation:
The goal that must be met before discharging Blanca and Maria from the hospital is D. Parents demonstrating proper care for Maria's needs.
Before a patient can be discharged from the hospital, it is important for the parents or caregivers to demonstrate that they are capable of providing the necessary care for the patient's needs. This includes things like administering medications, managing any medical equipment or devices, and following any specific instructions or protocols related to the patient's care.
For example, in the case of Maria who had cleft lip surgery scheduled (goal A), while the surgery itself may have been successful, it is crucial for her parents to show that they can properly care for her post-surgery needs before she can be discharged.
