A patient is admitted to the medical unit after experiencing chest pain. Which of these additional findings would support a diagnosis of cocaine abuse?

Cocaine is a central nervous system stimulant, increasing heart rate and blood pressure. Because of vasoconstriction, long-term intranasal use of cocaine is associated with a perforated nasal septum, as well as loss of smell. Reduced blood flow can also lead to gangrenous bowels and chronic diarrhea. Jaundice is related to impaired liver function; if present, it is usually due to viral hepatitis or concurrent alcohol use.
