Illness in one family member can affect the other family members. This is because family-centered nursing care recognizes that the family is the basic unit of society and that each member's health influences the whole family's health. Family-centered nursing care also involves collaborating with the family to provide care that meets their needs, preferences, and values. Choice A is wrong because the nurse does not provide family-centered nursing care to avoid the client’s loneliness. Loneliness is a psychosocial need, not a physiologic one, and it can be addressed by other means than involving the family. Choice B is wrong because the client’s compliance with medical instructions is not the primary goal of family-centered nursing care. Compliance is influenced by many factors, such as motivation, education, culture, and trust, and it may not always depend on the family’s involvement. Choice C is wrong because the family’s willingness to listen to instructions is not the main reason for providing family-centered nursing care. The nurse should respect the family’s autonomy and decision-making, and not impose instructions that may conflict with their beliefs or values.
