A 74-year-old man requires evaluation in the orthopedic ward four days after undergoing a right hip hemiarthroplasty for a femoral neck fracture. Over the last 12 hours, he has experienced progressively worsening shortness of breath, chest tightness, and a new-onset cough producing small amounts of clear sputum. His past medical history is significant for hypertension and moderate chronic obstructive pulmonary disease. His home medications, which include a daily fluticasone-salmeterol inhaler, were inadvertently not restarted after the procedure. His temperature is 38.1°C (100.6°F), blood pressure is 138/86 mmHg, pulse is 108/min, and respiratory rate is 22/min. Pulse oximetry shows 91% on room air. Physical examination reveals a prolonged expiratory phase and diffuse expiratory wheezing over all lung fields. There is no jugular venous distention, and heart sounds are normal without gallops or murmurs. The surgical incision is clean, dry, and intact with no surrounding erythema. There is no unilateral lower extremity edema. A chest radiograph demonstrates hyperinflated lung fields and flattened hemidiaphragms, without focal consolidation, pleural effusion, or pulmonary vascular congestion. An electrocardiogram shows sinus tachycardia without right heart strain. Which of the following is the most appropriate next step in the management of this patient?
- Administer systemic glucocorticoids and nebulized bronchodilatorsCevap
- BAdminister a dose of intravenous furosemide
- CBegin treatment with intravenous levofloxacin
- DObtain computed tomography pulmonary angiography
- EEncourage hourly use of an incentive spirometer
