A nurse is teaching a group of adults about screening and prevention of colorectal cancer. The nurse should describe which of the following as the most common sign of possible colon cancer?
Abdominal bloating and flank pain
Change in bowel habits
Unexplained weight gain
Development of new hemorrhoids
The Correct Answer is B
Choice A reason:
Abdominal bloating and flank pain may be associated with various gastrointestinal conditions, but they are not the most common signs of possible colon cancer.
Choice B reason:
This statement is correct. A change in bowel habits, such as persistent constipation, diarrhea, or a change in stool consistency, is the most common sign of possible colon cancer.
Choice C reason:
Unexplained weight gain is not typically associated with colon cancer; unexplained weight loss may be more indicative.
Choice D reason:
The development of new hemorrhoids is not a common sign of possible colon cancer.

Correct Answer is D
Explanation
Choice A reason:
Taking metronidazole with food can help reduce stomach upset. It is not typically recommended to take on an entirely empty stomach.
Choice B reason:
Metronidazole can cause drowsiness, but taking it at bedtime specifically for this reason is not a standard recommendation. It's more important to focus on avoiding alcohol.
Choice C reason:
Taking an extra dose without specific medical advice is not recommended. It's important to follow the prescribed dosing regimen.
Choice D reason:
Avoiding alcohol while taking metronidazole is crucial. The combination of metronidazole and alcohol can cause severe reactions, including nausea, vomiting, abdominal cramps, headache, and flushing. This interaction can occur for several days after discontinuing metronidazole, so it's essential to abstain from alcohol throughout the course of treatment.
Correct Answer is A
Explanation
Choice A reason:
A painless sore with raised edges is a characteristic early sign of oral cancer. It may appear as a small, painless lump or sore in the mouth, often with raised edges. This finding should raise suspicion and prompt further evaluation.
Choice B reason:
Diffuse inflammation of the buccal mucosa is a non-specific finding and can be caused by various factors, including infection or irritation. While it's important to assess the oral mucosa for any abnormalities, it is not specific to oral cancer.
Choice C reason:
Dull pain radiating to the ears and teeth is not a characteristic early sign of oral cancer. Pain associated with oral cancer may occur in later stages or if there is local invasion of nerves.
Choice D reason:
Areas of tenderness that make chewing difficult may occur for various reasons, including dental issues or other oral health problems. While this can be distressing for the patient, it is not specific to oral cancer.
