A nurse is caring for a client who experienced a lacerated spleen and has been on bedrest for several days. The nurse auscultates decreased breath sounds in the lower lobes of both lungs. The nurse should realize that this finding is most likely an indication of which of the following conditions?

A. Pulmonary edema: Pulmonary edema presents with crackles, dyspnea, and sometimes frothy sputum due to fluid accumulation in the alveoli. It does not usually manifest as decreased breath sounds in the lower lobes alone. B. Atelectasis: Prolonged bedrest reduces lung expansion, particularly in the lower lobes, leading to alveolar collapse and atelectasis. This condition is characterized by diminished or absent breath sounds in affected areas and is common in immobilized or post-injury clients. C. Delayed gastric emptying: This is a gastrointestinal complication, not a respiratory one. It may cause bloating or nausea but has no direct effect on lung sounds or breath sound assessment. D. An upper respiratory infection: Infections of the upper airway generally cause congestion, cough, and sometimes rhonchi or wheezes. They are not associated with decreased breath sounds localized to the lower lobes.
