The nurse is aware that a client with broken ribs is likely to have difficulty with:
1. Gas exchange.
2. Movement of the diaphragm.
3. Chest expansion on inspiration.
4. Movement of air through the bronchi.
Answer: 3
1. Broken ribs would not affect the exchange of air in the alveoli.
2. A broken rib is not likely to hamper movement of the diaphragm.
3. During inspiration, the intercostal muscles pull the ribs up and out to allow for expansion of the chest. If ribs are broken, expansion will be lessened, and there is severe pain.
4. Broken ribs will not affect the movement of air in the bronchi.
