Review Question - QID 212786

A 74-year-old man comes to the attention of the inpatient hospital team because he started experiencing shortness of breath and left-sided back pain 3 days after suffering a right hip fracture that was treated with hip arthroplasty. He says that the pain is sharp and occurs with deep breathing. His past medical history is significant for diabetes and hypertension for which he takes metformin and lisinopril. On physical exam, chest auscultation reveals mildly diminished breath sounds at the bases with faint bibasilar crackles, unchanged from his exam during morning rounds prior to his new dyspnea. His right calf is also swollen with erythema and induration. Given this presentation, which of the following most likely describes the status of the patient's lungs?
