A nurse is assessing a client who has COPD. The nurse should expect the client's chest to be which of the following shapes?

A. Remove the catheter: Removing the catheter may not be the immediate priority. The nurse should focus on preventing further air entry into the circulation and addressing the symptoms.

B. Replace the infusion system: While ensuring that the infusion system is intact is important, it is not the primary action needed to manage an air embolism.

C. Prepare for chest tube insertion: Chest tube insertion is not the primary intervention for an air embolism. The focus should be on preventing the progression of the embolism and providing supportive care.

D. Place the client on his left side in Trendelenburg position: This is the correct answer. Placing the client on the left side in Trendelenburg position is a maneuver used to trap air in the right atrium, preventing it from traveling to the pulmonary artery. The left side position helps to prevent the air from traveling to the right ventricle and into the pulmonary artery, reducing the risk of further complications.

A."I will follow a daily diet high in calories and protein": While maintaining adequate nutrition is important, emphasizing a diet high in calories may not be suitable. A balanced diet, including adequate protein, is recommended.

B."I will avoid getting a flu shot": Individuals with emphysema are at an increased risk of respiratory infections, including influenza. Getting a flu shot is generally recommended to reduce the risk of infection and complications.

C. "I will inhale slowly through pursed lips to help me breathe better."
This statement reflects a correct understanding of a beneficial breathing technique for individuals with emphysema. Inhaling slowly through pursed lips can help create back pressure in the airways, preventing them from collapsing and promoting better air exchange in the lungs. This technique can assist in managing shortness of breath and improving overall respiratory function.

D."I will lie on my stomach to practice abdominal breathing every day": While practicing abdominal breathing can be beneficial, lying on the stomach may not be the most practical or comfortable position for this purpose. The emphasis should be on proper breathing techniques, which can be done in various positions, including sitting or standing.
