A nurse is teaching a health promotion class about preventing cancer. Which statement by a client indicates understanding of gastric cancer risk factors?
"I should switch from regular to decaffeinated coffee to reduce my risk of gastric cancer."
"I should decrease eating salted, smoked, processed foods to reduce my risk of gastric cancer."
"I need to decrease fiber from my diet to reduce my risk of gastric cancer."
"I have been lactose-intolerant for many years, so I should have a yearly test for gastric cancer."
The Correct Answer is B
A. Switching from regular to decaffeinated coffee does not significantly impact gastric cancer risk. The main dietary risk factors include high intake of salted, smoked, and processed foods, not caffeine consumption.
B. Consuming large amounts of salted, smoked, and processed foods has been shown to increase the risk of gastric cancer. These foods contain nitrates and nitrites, which can be converted into cancer-causing compounds in the stomach.
C. High-fiber diets are generally protective against gastrointestinal cancers, including gastric cancer, rather than increasing the risk. A reduction in fiber intake could contribute to other gastrointestinal problems.
D. Lactose intolerance is not a known risk factor for gastric cancer. Regular testing for gastric cancer is not necessary for people who are lactose-intolerant unless they have additional risk factors, such as a family history of gastric cancer.

Correct Answer is A
Explanation
A. Requesting a prescription to culture the wound is the priority action because the presence of redness, warmth, and serosanguinous drainage could indicate an infection that needs to be confirmed and treated appropriately.
B. While antibiotics may be necessary if an infection is confirmed, it is crucial to first determine the presence of infection through culturing the wound.
C. Assuring the client that these findings are normal may delay necessary intervention if an infection is present, which could worsen the client's condition.
D. Cleaning the wound with sterile normal saline may be appropriate as part of wound care, but it does not address the underlying concern of possible infection and would not be prioritized over obtaining a culture.
Correct Answer is ["A","B","C"]
Explanation
A. An irregular border is a key characteristic of potentially cancerous skin lesions, particularly melanoma. Melanomas often have uneven, poorly defined edges.
B. Asymmetry is another sign of melanoma. If one half of a lesion does not match the other in shape or size, it should be evaluated by a healthcare professional.
C. Any lesion that has been increasing in size, particularly over a short period, is a concern and should be checked. Rapid growth can be a sign of malignancy.
D. A lesion with a diameter of less than 4 mm is generally less concerning, as most cancerous lesions are larger. However, the other factors (such as asymmetry and border irregularity) are more significant for diagnosis.
E. Ecchymosis (bruising) is not typically associated with cancerous skin lesions. Skin cancers like melanoma present as new or changing moles, not bruising.
