Which practice best prevents chemotherapy dosing errors?

• A. Use of full brand name of the drug
• B. Independent dose calculation
• C. Abbreviations for drug clarification
• D. Rely on height in inches for dosing

Answer: (B)

Independent dose calculation acts as a safety check because chemotherapy dosing often depends on body size measures like body surface area or weight and requires precise unit conversions. A second, independent calculation by another qualified clinician helps catch arithmetic mistakes, misread orders, or misapplied formulas before the drug is prepared or given, reducing the risk of dosing errors and ensuring the dose aligns with institutional protocols.

Using the brand name alone doesn’t guarantee accuracy and can introduce confusion with similar-sounding drugs. Abbreviations for drug names can lead to misinterpretation and errors. Relying on height in inches ignores weight and body surface area, which are essential for correct chemotherapy dosing.
