While shopping for an over-the-counter (OTC) cough suppressant, the nurse identifies that the medication will be classified as a:

A. Non-scheduled medication: OTC cough suppressants are typically classified as non-scheduled medications because they are not considered controlled substances and do not require a prescription for purchase. B. Schedule III medication: Schedule III medications are controlled substances with a moderate potential for abuse and dependence. OTC cough suppressants do not fall under this category. C. Schedule I medication: Schedule I medications are drugs with no accepted medical use and a high potential for abuse (e.g., heroin). OTC cough suppressants are not classified in this schedule. D. Schedule V medication: Schedule V medications are controlled substances with a lower potential for abuse. While some cough medications containing codeine may be Schedule V, common OTC cough suppressants do not fall under this category unless they contain specific controlled substances.
