The employee health nurse is providing care to an employee who was injured on the job. The client has a history of drug addiction and is currently enrolled in a 12-step recovery program
In order to determine whether the employee was impaired at the time of the accident, which diagnostic tool will the nurse use?
A) Liver enzymes
B) Stool guaiac
C) Urine toxicology testing
D) Hair testing
Answer: C
Urine toxicology testing will determine whether the employee had drugs in his system during the shift in which the injury occurred. Hair testing can detect substance use for up to 90 days and is not an accurate tool to determine whether the employee was impaired at the time of the injury. Liver enzymes detect liver damage but are not specific to damage from substance abuse. A stool guaiac tests for blood.
