The answer is B. Patients taking oral antineoplastic medications at home should not be instructed to use a urinal or bedpan instead of a toilet to reduce the risk of contamination via body fluids.
Use of a toilet is preferred over a urinal or bedpan for a patient on oral antineoplastic drugs. If a urinal or bedpan must be used, it should be handled with gloves and washed with soap and water after use.
The other answers are all patient and family education that should be provided to promote safe administration of oral antineoplastic agents in the home. The ONS oral chemotherapy guide provides additional patient and family information, and nurses can use the oral chemotherapy education sheets to teach patients and their families about specific medications.
