- A. Age
- B. Waist circumference
- C. Smoking
- D. All three options above
Correct Answer: D

The physician tells the patient that there will be an initial course of treatment with continued maintenance treatments and ongoing observation for signs and symptoms over a prolonged period of time. You can help the patient by reinforcing that the primary goal for this type of treatment is:
- A. Cure
- B. Control
- C. Palliation
- D. Permanent remission
Correct Answer: B
Rationale: The physician's plan initial treatment, maintenance, and long-term monitoring suggests a chronic cancer unamenable to cure, aiming instead to control growth and spread. Control stabilizes disease, extending life and quality, unlike cure, which eradicates cancer, or permanent remission, implying no recurrence both unfeasible here. Palliation focuses on symptom relief, not longevity, misaligning with ongoing treatments. Reinforcing control clarifies expectations, reducing anxiety by framing therapy as proactive management, not defeat. Nurses bolster this by explaining observation's role in adjusting care, aligning patient understanding with realistic goals, vital for adherence and emotional resilience in prolonged cancer battles.

Giddiness and drowsiness lag, hitting as brain sugar drops, a later neuroglycopenic fade, not the first alarm. Clinicians teach this split, pushing quick carbs at the front signs, a chronic drill to dodge the haze.
An oncology nurse educator is providing health education to a patient who has been diagnosed with skin cancer. The patient's wife has asked about the differences between normal cells and cancer cells. What characteristic of a cancer cell should the educator cite?
- A. Malignant cells contain more fibronectin than normal body cells
- B. Malignant cells contain proteins called tumor-specific antigens
- C. Chromosomes contained in cancer cells are more durable and stable than those of normal cells
- D. The nuclei of cancer cells are unusually large, but regularly shaped
Correct Answer: B
Rationale: Cancer cells sport tumor-specific antigens (e.g., CEA) proteins marking them as rogue, unlike normal cells. Fibronectin's less in malignant cells, aiding their slipperiness. Chromosomes are fragile and jumbled (aneuploidy), not stable. Nuclei are big and wonky (pleomorphic), not regular. Nurses in oncology education lean on this antigen trait it's why tests spot cancer and therapies target it, a clear line from normal to malignant.
