Final answer:
The nurse correctly delegates the care of the 81-year-old stable client with chronic heart failure and emphysema to the LPN, as the client's condition is likely stable and within the LPN's scope of practice.
Step-by-step explanation:
The nurse demonstrates correct delegation when assigning the 81-year-old client with chronic heart failure and emphysema, who was admitted 3 days ago, to the Licensed Practical Nurse (LPN) under the Registered Nurse's (RN) supervision. This client's condition is likely to be stable at this point, and the care for chronic conditions is within the scope of practice for an LPN. On the other hand, the client with exacerbation of COPD admitted 8 hours ago, the young client with a recent concussion, and the client newly diagnosed with GERD who is being discharged today may require more complex care or assessments that are more appropriate for an RN to manage or to be directly involved with.
