“I can’t breathe and my chest hurts.”
Todd Jefferson is a 38-year-old African-American man with a history of sickle cell anemia who presents to the local community hospital ED with pain. On waking up three days prior to admission, he experienced a sudden onset of pain in his hands, legs, and lower back. He began taking oxycodone 15 mg every 4 hours at that time with minor pain relief. This morning he experienced a fever of 102°F, progressive shortness of breath, and priapism, which caused him to seek treatment at the ED. Patient acknowledged having sick contacts at his workplace.
