A client who will be undergoing chemotherapy and internal radiation for cancer treatment asks the nurse why they are scheduled for the placement of a central venous access device (CVAD). Which of the following is a benefit of placing a CVAD for someone who will be undergoing cancer treatment?
Allows for long-term administration of chemotherapy
Can be used to implant radioactive material for internal radiation treatments
Eliminates the risk of infection associated with accessing a blood vessel
Reduces the risk of nausea and vomiting caused by chemotherapy medication
The Correct Answer is A
A. Chemotherapy often requires multiple infusions over a long period, and a CVAD provides a reliable and convenient access point for these treatments. It allows for the continuous or intermittent administration of chemotherapy drugs, which are often irritating to veins and require precise dosing.
B. While CVADs are used for administering chemotherapy and other treatments, they are not typically used to implant radioactive material for internal radiation (brachytherapy).
C. While CVADs reduce the need for repeated venipunctures and can help manage the complications of frequent injections, they do not eliminate the risk of infection. CVADs can themselves become a source of infection if not properly maintained, as they are open to the external environment.
D. The placement of a CVAD does not directly affect the side effects of chemotherapy, such as nausea and vomiting. The CVAD’s role is primarily related to the administration of medications and access to blood vessels.

Correct Answer is D
Explanation
A. While vitamin A can interact with some medications, it does not have a significant effect on verteporfin.
B. Verteporfin does not typically affect blood sugar levels.
C. Verteporfin is usually administered intravenously, so it is not taken orally.
D. Verteporfin is a photosensitizing agent used in photodynamic therapy for age-related macular degeneration. After treatment with verteporfin, the client should avoid sunlight and other intense light for several days to prevent a severe sunburn-like reaction. This is because verteporfin makes the skin and eyes more sensitive to light.
