Final answer:
After coronary artery bypass graft surgery, once a patient doesn't need intensive care, they should be transferred to a Sub-acute or Step-down unit for continued monitoring and care.
Step-by-step explanation:
Once a patient has recovered sufficiently from coronary artery bypass graft surgery and no longer requires intensive care in the coronary intensive care unit, the nurse should prepare to transfer the client to a Sub-acute or Step-down unit. This type of unit is designed for patients who no longer need critical care but still require closer monitoring and medical care than is typically provided on a general medical floor. Patients in a step-down unit receive a higher level of nursing care and more frequent monitoring than in a general ward, which is essential for their continued recovery after a major cardiac procedure.
