Correct Answer: C

Rationale: In the context of AML, the 5-year survival rate significantly decreases with age. The 5-year survival rate for patients over 75 years old is less than 2% compared to 43% for those 50 years or younger, and 19% for those between 50 and 64 years. Choice A is incorrect as early diagnosis does not necessarily guarantee good outcomes in AML. Choice B is inaccurate as the 5-year survival rate is not approximately 50% for older adults with AML. Choice D is incorrect as survival rates for AML patients are influenced by various factors beyond just the pre-illness level of health.

Correct Answer: A

Rationale: The correct answer is A: Bowel sounds. Checking for bowel sounds is crucial before administering any diet to ensure the gastrointestinal tract is functioning properly following surgery. This assessment helps prevent complications such as paralytic ileus. Choices B, C, and D are not the priority in this situation. While the ability to ambulate, incision appearance, and urine specific gravity are important assessments, ensuring bowel function takes precedence in this postoperative scenario.

Correct Answer: C

Rationale: Choice C is the most therapeutic response as it acknowledges the patient's anxiety and encourages reflection on his behavior. This approach can help the patient explore his feelings and thoughts about smoking in relation to his surgery, promoting self-awareness and potentially opening the door for a constructive discussion. Choices A and B are more directive and may not address the underlying anxiety and need for reflection. Choice D is also somewhat permissive about smoking before surgery, which may not be in the patient's best interest.

Correct Answer: B

Rationale: The most appropriate response for a patient presenting with a firm, painless cervical lymph node and denying recent infectious diseases is to promptly refer the patient for medical assessment. This is crucial to rule out serious underlying conditions such as malignancy or other concerning causes. Calling 911 is not necessary in this situation as it is not an emergency. Ordering a radiograph may not be the most immediate or appropriate action, as further evaluation by a healthcare provider is needed first. Encouraging the patient to wait and track the lymph node for a week is not advisable when a potential serious condition needs to be ruled out promptly.

Correct Answer: D

Rationale: A diet high in fiber is not a risk factor for gastric cancer; in fact, it is generally considered protective against cancers. High sodium intake (Choice A) has been associated with an increased risk of gastric cancer. Diets with high amounts of chili garlic (Choice B) may irritate the stomach lining, potentially contributing to the development of gastric cancer. Smoking (Choice C) is a well-established risk factor for various types of cancers, including gastric cancer.
