The nurse has conducted a cancer prevention community education program. In evaluating the participants understanding of the carcinogens, which statement indicates an accurate understanding?
Carcinogens are substances that contain cancerous cells.
Substances that change a cell so that it becomes cancerous are potential sources of cancer.
Environmental factors such as sunlight and chemicals can cause cancer to spread.
Carcinogens are in the environment and cannot be avoided.
The Correct Answer is B
A. Carcinogens are substances that contain cancerous cells:
This statement is incorrect. Carcinogens are substances that have the potential to cause cancer, but they do not necessarily contain cancerous cells themselves.
B. Substances that change a cell so that it becomes cancerous are potential sources of cancer:
This is the correct answer. Carcinogens are agents that can induce changes in the genetic material of cells, leading to the development of cancer. They can initiate or promote the process of carcinogenesis.
C. Environmental factors such as sunlight and chemicals can cause cancer to spread:
This statement is not accurate. Carcinogens can contribute to the initiation or promotion of cancer, but the spread of cancer (metastasis) involves complex biological processes and is not directly caused by environmental factors.
D. Carcinogens are in the environment and cannot be avoided:
This statement is not accurate. While carcinogens may be present in the environment, efforts can be made to minimize exposure and adopt preventive measures. Avoidance of known carcinogens and the promotion of a healthy lifestyle can contribute to cancer prevention.

Correct Answer is D
Explanation
A. Thick skin plaques topped by silvery white scales:
This is a characteristic presentation of psoriasis vulgaris, not an indicator of overexposure to PUVA.
B. Tenderness upon palpation and generalized erythema:
This may be associated with various skin conditions but is not specific to overexposure to PUVA.
C. Brown, rough, greasy, wart-like papules on the face:
This description is not consistent with the expected outcomes or side effects of PUVA treatment.
D. Requires sunglasses because sunlight hurts the eyes.
PUVA treatment involves the use of psoralen, a light-sensitizing medication, followed by exposure to ultraviolet A (UVA) light. Overexposure to PUVA can lead to phototoxic reactions, including eye sensitivity to sunlight (photophobia). If the client requires sunglasses because sunlight hurts the eyes, it suggests that the eyes have been affected by the treatment, and the nurse should intervene to prevent further damage.
Correct Answer is D
Explanation
A. Type 2 diabetes mellitus
Type 2 diabetes mellitus is not a contraindication for peritoneal dialysis. In fact, peritoneal dialysis can be a suitable option for individuals with diabetes who require renal replacement therapy. However, the presence of diabetes may require additional considerations and close monitoring.
B. Nephrotic syndrome history
Having a history of nephrotic syndrome is not a contraindication for peritoneal dialysis. Peritoneal dialysis can be used in individuals with various causes of chronic kidney disease, including those with nephrotic syndrome.
C. Latent hepatitis C
Latent hepatitis C alone may not be an absolute contraindication for peritoneal dialysis. However, the decision to initiate peritoneal dialysis would depend on the overall health status of the client, the degree of liver involvement, and the risk of infection. Close monitoring and appropriate precautions may be necessary.
D. Crohn's disease with colectomy
Crohn's disease with colectomy is considered a contraindication for peritoneal dialysis. Surgical alterations in the abdomen, such as colectomy, can lead to adhesions or other complications that may interfere with the effectiveness of peritoneal dialysis. In such cases, alternative forms of dialysis, such as hemodialysis, may be considered.
