You are working at a night clinic as a nurse supervisor and are assessing an elderly male (72 years old) who came in complaining of cough, shortness of breath, fever, and chest pain. He states his cough is productive with rust-colored sputum. He also states that about one week ago, he began to experience symptoms such as a runny nose and upper respiratory congestion which he treated with over-the-counter medications. His symptoms gradually worsened with a sudden fever and intense, shaking chills. The patient appeared cyanotic and was having trouble breathing.
