Nurses are subject to drug testing due to their responsibility for patient care, including administering medications. Medical facilities may conduct random drug tests and test nurses based on reasonable suspicion, such as patient complaints or unusual behavior. Additionally, drug tests may be performed if medicinal drugs go missing. Nurses are often required to undergo more frequent random drug tests than employees in other professions. This is to protect patients and create accountability for the nurses, as the stressful nature of the job can lead to unhealthy coping mechanisms.
