Correct Answer: C

Rationale: The correct answer is C: Obesity. Obesity is a known risk factor for colon cancer as it can lead to chronic inflammation and changes in hormone levels, increasing the risk of developing cancerous cells in the colon. Smoking (choice A) is more strongly associated with lung cancer. Heavy alcohol consumption (choice B) is linked to increased risk of liver and esophageal cancer, not colon cancer. Saccharin consumption (choice D) has not been definitively linked to colon cancer. In summary, obesity is the most relevant risk factor for colon cancer among the choices provided.

Correct Answer: B

Rationale: The correct answer is B: Take the NSAID with meals. Taking NSAIDs with meals helps reduce stomach irritation and risk of developing ulcers. Food acts as a protective barrier and helps in the absorption of the medication. Incorrect Choices: A: Taking NSAID with aspirin can increase the risk of stomach irritation and bleeding due to combined antiplatelet effects. C: Orange juice does not potentiate the effect of NSAIDs and may even worsen stomach irritation due to its acidity. D: NSAIDs do not coat the stomach lining; in fact, they can irritate the stomach lining and increase the risk of ulcers.

Correct Answer: A

Rationale: The correct answer is A: Increase fluid intake. This is important for a client undergoing radiation and chemotherapy for non-Hodgkin's lymphoma to prevent dehydration, help flush out toxins, and support kidney function. Increasing fluid intake can also help manage side effects like nausea and vomiting. Choices B, C, and D are incorrect because low-fat meals, soft bland foods, and foods rich in folic acid are not specifically indicated for clients undergoing radiation and chemotherapy for non-Hodgkin's lymphoma.

Correct Answer: A

Rationale: The correct answer is A: Fruits such as bananas. Bananas are high in potassium, which is essential for various bodily functions like muscle contractions and maintaining fluid balance. Fruits are a natural source of potassium and are easily incorporated into the diet. Milk and yogurt (B) are good sources of calcium, not potassium. Green leafy vegetables (C) are nutritious but may not provide as much potassium as fruits. Nuts and legumes (D) are good sources of protein and healthy fats but are not as rich in potassium as fruits like bananas.

Correct Answer: C

Rationale: The correct answer is C because it helps the patient explore her support system. By asking who she usually goes to when facing problems, the nurse encourages the patient to identify her sources of emotional support, which can help her cope with the new diagnosis. This response acknowledges the patient's need for support and fosters a therapeutic relationship. Explanation for incorrect choices: A: "Don't worry. You'll be okay." - This response dismisses the patient's feelings and offers false reassurance, which may not address her emotional needs. B: "The treatments you are receiving will make you feel better very soon." - While this statement provides information about treatment, it does not directly address the patient's difficulty in coping with the diagnosis. D: "Have you made end-of-life decisions?" - This response may be premature and could unnecessarily increase the patient's anxiety about her prognosis.
