A 28 y/o male comes to the emergency room complaining of 6 days of fever with shaking chills. Over the past two days he has also developed a productive cough with greenish sputum. He has also noticed that occasionally the sputum is blood streaked. He reports to having no dyspnea, but sometimes he does experience chest pain upon deep inspiration. He does not have headaches, abdominal pain, urinary symptoms. No nausea, vomiting, or diarrhea. No significant past medical history. He does smoke. He drinks several beers daily. Denies IV drug use. Upon physical examination, his oral temperature was recorded at 102.5 degrees F. His heart rate was 109 bpm and his BP was 128/76. His respiration count was 23 per minute. He was alert awake and oriented. He has no oral lesions and his fundoscopic exam was normal. He has no JVD and his heart was appreciated with tachycardia and had a harsh holosystolic murmur heard at the left lower sternal border that increased with inspiration.
