Exercise 3

As a health care worker in a busy health maintenance organization (HMO), you work with dozens of patients each day. You've noticed that each of the following three patients who were treated today has been prescribed a drug that could cause problems. For each patient, identify and explain the potential drug problem.
a. Patient A came to the HMO this morning complaining of muscle pain following a back injury. He was prescribed the muscle relaxant cyclobenzaprine. Patient A is always joking with the nurses about how much he drinks. It's clear that he takes several drinks of whiskey every day.
b. Patient B came into the HMO last week with strep throat, for which he was prescribed streptomycin. Today, he's complaining of neck and shoulder pain, which he attributes to driving his car for a total of 20 hours over the past 2 days. Patient B was prescribed metaxalone for the muscle pain.
c. Patient C takes lidocaine for a heart arrhythmia. Yesterday, she injured herself doing calisthenics and spent a sleepless night in pain. Today, she visited the doctor and was prescribed methocarbamol to relax her sore muscles.
