What symbol must narcotic stock bottles have?

The correct answer is that narcotic stock bottles must bear the symbol "N." This designation serves a crucial role in pharmacy practice by clearly identifying medications that contain narcotics, which are controlled substances.

The "N" symbol helps pharmacy staff quickly recognize these products, ensuring that appropriate safeguards and procedures are followed in their handling, storage, and dispensing. This identification is essential for compliance with regulations surrounding the management of controlled substances and helps prevent misuse or diversion.

Each regulated symbol, including the "N," is part of a broader system of labeling that aids in maintaining safety and accountability within pharmacy operations. In contrast, the other symbols mentioned (C, T/C, R) pertain to different classifications of substances or medications and do not specifically indicate narcotic content. This distinction is critical for pharmacists and technicians to ensure adherence to legal standards and promote patient safety.
