In risk assessment, which combination of factors is considered?

• A. Type of HD, dosage form, risk of exposure, prepackaged and manipulation
• B. Type of HD alone
• C. Risk of exposure only
• D. Prepackaged status only

Answer: (A)

In risk assessment for hazardous drugs, multiple interacting factors shape how dangerous a handling task can be and what controls are needed. The intrinsic hazard comes from the drug type itself, but the risk also depends on how the drug is presented—the dosage form—which affects how easily it can be spilled, aerosolized, or absorbed. The likelihood of exposure is determined by the specific tasks and workflows involved, such as drawing, compounding, or administration, and how frequently they occur. Finally, whether the product is prepackaged or must be manipulated (reconstituted, mixed, or drawn into syringes) changes the level of containment and protective measures required. Putting these elements together gives a complete risk picture and guides appropriate controls, such as containment devices, ventilation, and proper PPE.

Relying on only one aspect, like just the drug type or just the exposure risk or just packaging status, fails to capture how these dimensions interact. For example, a highly hazardous drug may pose less exposure risk if it’s prepackaged and requires no manipulation, but it could present significant risk if it must be manipulated.
