Correct Answer: D

Rationale: The course of polycythemia vera can be best ascertained by monitoring the patient's hematocrit, which should remain below 45%. Hematocrit levels are a key indicator in assessing the progression of the disease. Choices A, B, and C are not the most appropriate methods for gauging the course of polycythemia vera. Monitoring the color of the patient's palms and face, or their response to erythropoietin injections, may not provide an accurate reflection of the disease's progression. Similarly, while erythrocyte sedimentation rate can be affected in polycythemia vera, it is not the primary marker for monitoring the disease's course.

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: 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: 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: A

Rationale: Clients are often overwhelmed by a sudden cancer diagnosis; therefore, it is best for the nurse to call the client at home the next day to review teaching. This approach allows the client time to process the information before the surgery. Choice B may be beneficial but is not the priority at this time. Providing written instructions (Choice C) is helpful but does not offer the personalized interaction needed. Reassuring the client (Choice D) is important but does not address the educational aspect of preoperative preparation.
