Problem: Bill, Ann, and Connie are in different clinical sections at separate facilities. As they discuss their clinical experiences, they note some variances in nursing care delivery. Bill says that at his facility there is one charge nurse who is responsible for the functions of others-medication nurse, treatment nurse, several nursing assistants, and secretaries. Ann relates that her hospital uses a patient-focused care model, whereby the nurse supervises all those who come into contact with the patient. She explains that the aides are trained in dietary education and that the lab draws are done by the nurse. Connie describes how she participated in a meeting in which the dietitian, respiratory therapists, nurses, aides, and a physician met to discuss the more complicated patient cases. She explains how the facility uses a care map that shows each day and details outcomes the patient should achieve daily to move forward. 1. What are the three patterns of nursing care delivery described? 2. Which of the patterns described would benefit the intensive care patient? Why? 3. Although each of the various models works toward quality patient care, which pattern of care delivery makes the best use of available resources? Defend your answer.
