Correct Answer: C

Rationale: The correct answer is C: Diagnostic reasoning. The nurse is using assessment data to analyze, interpret, and make a judgement about the patient's condition. This process involves critical thinking skills to develop a nursing diagnosis. Choice A (Assigning clinical cues) is incorrect because it refers to identifying specific signs and symptoms. Choice B (Defining characteristics) is incorrect as it pertains to the features of a diagnosed condition. Choice D (Diagnostic labeling) is incorrect because it focuses on naming a specific nursing diagnosis. Diagnostic reasoning encompasses the entire process of analyzing data, making connections, and formulating a nursing diagnosis based on critical thinking.

Correct Answer: B

Rationale: The correct answer is B: Ineffective airway clearance related to obstruction by a tumor or secretions. This takes highest priority as compromised airway can lead to respiratory distress and potential respiratory failure. Maintaining clear airways is essential for oxygenation and ventilation. Choices A, C, and D are important but do not pose immediate life-threatening risks compared to compromised airway. Disturbed body image, anxiety, and imbalanced nutrition can be addressed once the airway clearance is stabilized.

Correct Answer: C

Rationale: The correct answer is C: Performing a physical examination. This method allows the nurse to collect objective data directly from the patient, which is crucial in establishing a comprehensive patient database. By assessing the patient's physical condition, the nurse can gather vital information such as vital signs, overall health status, and potential areas of concern. Reviewing literature (A) and checking orders for tests (B) may provide additional insights but are not direct data collection methods. Ordering medications (D) is a treatment intervention, not a data collection method.

Correct Answer: D

Rationale: The correct answer is D: All of the above. Involvement of the sacral plexus can affect bladder control, leading to bladder problems. It can also impact bowel function, requiring bowel management. Additionally, the sacral plexus plays a role in sexual function, so assessment should include sexual activity. Therefore, all options are relevant when assessing a disease process involving the sacral plexus. Other choices are incorrect as they do not cover the comprehensive assessment needed for this specific condition.

Correct Answer: B

Rationale: The correct answer is B: radiation therapy. Radiation therapy uses high-energy radiation to target and destroy cancer cells while minimizing damage to surrounding healthy tissues. It is a localized treatment that is effective in shrinking tumors and preventing cancer cell growth. Surgery (A) involves physically removing the tumor and surrounding tissues, while chemotherapy (C) uses drugs to kill cancer cells throughout the body. Palliative treatment (D) focuses on symptom management and improving quality of life in advanced stages of cancer. In this case, the focus is on a form of cancer therapy involving high-energy electromagnetic radiation, making radiation therapy the most appropriate choice.
