Correct Answer: C

Rationale: The correct answer is that normal cells undergo apoptosis, which is a programmed cell death process essential for maintaining tissue homeostasis. Choice A is incorrect as normal cells do have specific functions. Choice B is incorrect as the size of the nucleus may vary but is not a defining characteristic of normal cells. Choice D is incorrect as the color of the nucleus is not a standard characteristic of normal cells.

Correct Answer: C

Rationale: For patients experiencing difficulties with oral intake, the provision of small, easily chewed meals may be beneficial. Option A (TPN) and B (PEG tube placement) are more invasive interventions and should be considered if non-oral routes are necessary. Option D is not appropriate as the primary responsibility for a patient's nutrition should lie with healthcare professionals to ensure proper management and monitoring.

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: 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.

Correct Answer: B

Rationale: The patient's signs of ecchymoses and petechiae are suggestive of thrombocytopenia, which is a common complication of leukemia. Thrombocytopenia is a condition characterized by a low platelet count, leading to abnormal bleeding. Checking the patient's most recent platelet level is crucial to assess the severity of thrombocytopenia and guide further interventions. Initiating measures to prevent venous thromboembolism (VTE) (Choice A) is not directly related to the patient's current signs. Placing the patient on protective isolation (Choice C) is not necessary for ecchymoses and petechiae. Ambulating the patient (Choice D) is not appropriate without addressing the underlying cause of abnormal bleeding.
