A 16-year-old boy is brought to the clinic by his father who says that he has been
increasingly aggressive and has been stumbling and tripping around the house for several
weeks. He is especially worried about his uncharacteristic violent behavior. The patient's
temperature is 38 C (100.4 F), blood pressure is 140/90 mm Hg, pulse is 90/ min, and
respirations are 22/min. He has slightly dilated pupils and nystagmus. He begins to have
convulsions on the table, making the remainder of the examination impossible. Which of
the following is the most likely cause of these findings?
A. Cocaine withdrawal
B. Heroin
C. Marijuana
D. Morphine
E. Phencyclidine (PCP)
