Which of the following illustrates a characteristic of Schedule II Narcotics?

The correct choice highlights a key characteristic of Schedule II narcotics, which is the requirement for a prescription and the prohibition of refills. This classification indicates that these substances are considered to have a high potential for abuse, leading to severe psychological or physical dependence. Because of their potential for misuse, federal regulations mandate that Schedule II drugs cannot be refilled; a new prescription is required each time. This regulation helps to prevent misuse and ensures that patients use these medications under careful medical supervision.

In contrast, the other options do not accurately reflect the nature of Schedule II narcotics. Mild physical dependence does not apply, as these substances can lead to more severe forms of addiction. Including over-the-counter medications misrepresents the classification, as Schedule II narcotics are prescription medications that are not available over-the-counter. Finally, stating that there is no potential for abuse contradicts the very definition of Schedule II narcotics, which is characterized by their significant risk for abuse and dependence.
