Carcinogens are factors related to the formation of various malignancies. Which factor has the greatest impact on the development of all cancers?
chemical agents
environmental factors
viruses
defective genes
The Correct Answer is B
A. Chemical agents: Chemical agents (e.g., tobacco smoke, asbestos) are significant carcinogens but are not the most influential across all types of cancer.
B. Environmental factors: Environmental factors, including exposure to radiation, chemicals, and lifestyle choices, have a broad impact on cancer development. This is the most comprehensive factor, as it encompasses various elements that contribute to cancer risk.
C. Viruses: Certain viruses (e.g., HPV, Hepatitis B) are linked to specific cancers, but they are not the primary cause of most cancers.
D. Defective genes: Genetic mutations play a critical role in cancer development, but they are often triggered by environmental factors, making environmental factors the most significant overall.

Correct Answer is C
Explanation
A. Wear sterile gloves. Sterile gloves are typically required for invasive procedures, not general care after chemotherapy. The key concern here is exposure to chemotherapy agents in bodily fluids.
B. Place incontinence pads in the regular trash container. Incontinence pads and other items contaminated with bodily fluids should be disposed of in a hazardous waste container, not regular trash, to prevent exposure to chemotherapy agents.
C. Wear personal protective equipment when handling blood, body fluids, and feces. Chemotherapy agents can be excreted in bodily fluids, so wearing PPE is essential to protect the healthcare worker from exposure.
D. Provide a urinal or bedpan to decrease the likelihood of soiling linens. While providing a urinal or bedpan may be practical, it does not address the key concern of handling potentially contaminated bodily fluids safely.
Correct Answer is B
Explanation
A. The client can obtain and maintain employment. While obtaining and maintaining employment can be a positive outcome, it does not specifically address the control of aggressive behaviors which are the focus here.
B. The client is free from aggressive behaviors. Being free from aggressive behaviors directly reflects successful treatment of aggressive symptoms in schizophrenia. This outcome specifically addresses the primary concern.
C. The client utilizes relaxation techniques. Utilizing relaxation techniques can be part of managing symptoms but does not directly measure the control of aggressive behaviours.
D. The client maintains healthy relationships with others. Maintaining healthy relationships is a positive outcome, but it is a broader goal and does not directly indicate control of aggressive behaviours.
