Final answer:
A nurse is responsible for assessing, making nursing diagnoses, planning, implementing, and evaluating nursing care, playing a central role in patient care within the healthcare team.
Step-by-step explanation:
The health team member who assesses, makes nursing diagnoses, plans, implements, and evaluates nursing care is a nurse. Nurses are trained healthcare professionals who work closely with patients to ensure their physical and psychological needs are met. The process of providing nursing care involves a multi-step approach: assessing the patient to determine their needs, making nursing diagnoses to identify potential or actual health problems, planning personalized care strategies, implementing the planned nursing interventions, and continually evaluating the effectiveness of the care provided to ensure the patient's health goals are being met.
