Case 1:

Ms. G. is a 76 year-old Hispanic female who presents to your urgent care clinic with headache, blurry vision, and shortness of breath. She reports that these symptoms began approximately one week ago. Ms. G. is a migrant farm worker from Mexico and has never had a primary care physician in this country.

Via an interpreter, you learn that Ms. G. has a past medical history of diabetes mellitus, for which she takes an oral medication prescribed by a physician in Mexico. She denies any other medical problems.

Ms. G.’s vital signs are as follows:

Heart rate 99
Blood pressure 190/110
Respirations 12/min
Temperature 96.9 F
Weight 220 pounds (100 kg)
Height 5’ 3”

Ms. G. repeatedly denies any prior history of hypertension. You question her about illicit drug use and she vehemently denies this. At last, you ask her if she takes herbal medicines and she replies that she obtained a preparation from a family member in Mexico, who purchased it from a pharmacy in Juarez. Ms. G. tearfully explains that she has been struggling with obesity and had been told that the compound would be helpful. She has lost approximately 20 pounds since she began taking it about a month ago.
