Which of the following is listed as a common route of exposure to chemotherapy agents?

• A. Cleaning up chemo spills
• B. Assessing the patient with cancer
• C. Drug administration
• D. Drug vaporization

Answer: (D)

Exposure to chemotherapy agents happens when staff come into contact with the drug through routes like inhalation, dermal absorption, ingestion, or needle-stick exposure. The option that describes inhaling airborne drug particles or vapors directly represents how exposure can occur, especially since some agents can volatilize or become aerosolized during preparation or administration. This makes inhalation of drug vapors a common exposure route in practice. Cleaning up spills is a safety scenario that can lead to exposure if precautions aren’t followed, but it’s not the route itself; administering the drug and assessing the patient are clinical tasks, not exposure pathways.
