Case Study^

Three high school students are being evaluated by health care providers at a drug re-

habilitation clinic that serves adolescents. Hector, a 15-year-old boy, appears agi-tated

and restless. He tells his health care provider that he is having muscle spasms. Upon

examination, the care provider notes that Hector has a rapid heart rate and a dan-

gerously high blood pressure. Carolyn, a 16-year-old girl, is being reassessed following a

visit to the emergency room last night. According to her ER records, Carolyn was at a

party with her friends when she suddenly had a seizure. Her records also document that

she had an abnormal heart rate upon admission. Dante, a 14-year-old boy, was also

admitted to the ER the night before. Dante’s parents found him lying on the couch in a

deep sleep. When they could not arouse their son, they rushed him to the hospital where

he experienced a convulsion. Later that night, Dante’s parents discovered medi-^

cation hidden in his room that his mother had used earlier, following major surgery.

Review Questions

3.^ What type of drug do you think Hector might be using?^
4.^ What long-term problems can this type of drug cause?^
5.^ What drug likely caused Carolyn’s seizure and abnormal heart rhythm?^
6.^ How do users obtain the most dramatic “high” when using this drug?^
7.^ What drug might have caused Dante’s symptoms?^
8. Do you think the drug Dante used is legal or illegal, or does it depend on the
circumstances?
