Final answer:
Breath sounds that are clear bilaterally indicate that the client does not have respiratory complications following a hemiarthroplasty, as this suggests healthy lung function without obstruction or fluid.
Step-by-step explanation:
The practical nurse is caring for a client who has just had a hemiarthroplasty. Among the assessment findings, breath sounds that are clear bilaterally would indicate that the client does not have respiratory complications. This finding suggests that the lungs are functioning properly and air is moving through both the left and right sides without obstruction or fluid accumulation which could suggest pneumonia or other lung conditions. In contrast, a productive cough with yellow mucus, elevated respiratory rates, or the use of an incentive spirometer do not definitively demonstrate the absence of respiratory issues. Incentive spirometry is often used as a preventive measure to encourage deep breathing and prevent postoperative pneumonia. A productive cough with yellow mucus could indicate an infection. Therefore, clear bilateral breath sounds are the most reassuring indicator among the options provided.
