Problem:
John is a 62-year-old male who underwent a total knee replacement 8 hours ago. He is on a morphine infusion to manage his post-operative pain. One hour ago, he was complaining of 8/10 pain to his left knee. His wife calls the nurse into his room as she is concerned about her husband's breathing. On assessment, the nurse notes the following vital signs: T 36.2C, HR 74, RR 6, BP 108/60, oxygen sats 84% in room air. Lung sounds are clear on auscultation. Air entry and chest movement is decreased. John responds to painful stimuli.
