[Answered]: Mr

Mr. Johnson is a 72-year-old man admitted to your unit with a history of COPD (chronic obstructive pulmonary disease) and high blood pressure. He is short of breath when walking to the bathroom and needs to rest often. His oxygen saturation is 89% on room air, and he tells you he sometimes skips his blood pressure pills because they make him feel tired. What are some signs that Mr. Johnson might be having trouble with his breathing or circulation? What nursing actions can you take to help improve his oxygen levels and make him more comfortable?
