Step-by-step explanation:
A realistic short-term goal for a client with end-stage chronic obstructive pulmonary disease (COPD) would be to improve lung function through breathing exercises and medication adherence. For example, the client can work with a respiratory therapist to learn deep breathing techniques and use a nebulizer to deliver medication directly to the lungs. By consistently practicing these exercises and taking the prescribed medication, the client can improve their ability to breathe and manage their symptoms.
