1.
Which of the following is not a screening test for Colorectal Cancer?
Correct Answer
B. Endarterectomy
Explanation
Endarterectomy is a surgical procedure used to remove plaque buildup from the arteries, typically in the carotid artery. It is not a screening test for colorectal cancer. Screening tests for colorectal cancer include colonoscopy, sigmoidoscopy, barium enema, and fecal occult blood test. These tests are used to detect and diagnose colorectal cancer or precancerous polyps in the colon and rectum. Endarterectomy is unrelated to colorectal cancer screening and is used to treat atherosclerosis in the arteries.
2.
Which of the following is not a risk factor for Colorectal Cancer?
Correct Answer
D. Low levels of mercury on the blood stream
Explanation
Low levels of mercury in the bloodstream are not a risk factor for colorectal cancer. Colorectal cancer is primarily influenced by factors such as age, history of certain types of cancer, and family history of colorectal cancer. Mercury exposure is not directly linked to the development of colorectal cancer, therefore low levels of mercury in the bloodstream do not increase the risk of this type of cancer.
3.
Which of the following is most important in the prevention of Colorectal Cancer?
Correct Answer
A. Early detection of polyps and colorectal cancer
Explanation
Early detection of polyps and colorectal cancer is the most important factor in the prevention of Colorectal Cancer because it allows for timely intervention and treatment. By detecting and removing polyps early, the risk of them developing into cancer is significantly reduced. Similarly, detecting colorectal cancer in its early stages increases the chances of successful treatment and improves the overall prognosis for the patient. Regular screenings and tests, such as colonoscopies, are crucial in identifying any abnormalities and ensuring early detection.
4.
Which of the following stages is characterized by a tumor on the innermost layersof the colon?
Correct Answer
B. Stage 0
Explanation
Stage 0 is characterized by a tumor on the innermost layers of the colon. This stage is also known as carcinoma in situ, where the tumor is confined to the inner lining of the colon and has not spread to nearby tissues or lymph nodes. It is considered the earliest stage of colon cancer and has a high chance of successful treatment and a good prognosis.
5.
Which form of treatment is advised for Stage 4 Colorectal Cancer?
Correct Answer
A. Surgery
Explanation
Surgery is the recommended form of treatment for Stage 4 Colorectal Cancer. This is because surgery allows for the removal of the tumor and surrounding tissues, which can help in controlling the spread of cancer and improving the patient's prognosis. Surgery may be combined with other treatments such as chemotherapy or radiation therapy to further enhance the effectiveness of the treatment.
6.
Which of the following is not used as a chemotherapeutical agent for colorectal cancer?
Correct Answer
A. Zofran
Explanation
Zofran is not used as a chemotherapeutic agent for colorectal cancer. Zofran, also known as ondansetron, is an antiemetic medication commonly used to prevent nausea and vomiting caused by chemotherapy. However, it is not directly used to treat colorectal cancer. On the other hand, Fluorouracil, Oxaliplatin, and Irinotecan are all chemotherapeutic agents commonly used in the treatment of colorectal cancer.
7.
Which of the following is not a common side effect of chemotherapeutical treatment for colorectal cancer?
Correct Answer
D. Hair loss
Explanation
Hair loss is not a common side effect of chemotherapeutic treatment for colorectal cancer. Chemotherapy drugs are designed to target rapidly dividing cells, such as cancer cells, but they can also affect healthy cells that divide rapidly, such as hair follicle cells. This can lead to hair loss as a side effect of chemotherapy. However, hair loss is more commonly associated with treatments for other types of cancer, such as breast or ovarian cancer, rather than colorectal cancer.
8.
Which of the following is not a home treatment for mouth sores resulting from chemotherapeutical treatment for colorectal cancer?
Correct Answer
D. Hot packs applied to the jaw
Explanation
Hot packs applied to the jaw are not a home treatment for mouth sores resulting from chemotherapeutical treatment for colorectal cancer. This is because hot packs can further irritate the mouth sores and increase discomfort. Drinking cold liquids can provide relief by numbing the area, using a straw can help to avoid direct contact with the sores, and rinsing with warm salt water can help to clean the sores and promote healing.
