Correct Answer: A

Rationale: The correct answer is A: Palliative surgery. In this scenario, the patient's colon cancer has already progressed to stage IV with metastasis to the liver, indicating an advanced and incurable condition. Palliative surgery aims to alleviate symptoms, improve quality of life, and prolong survival without aiming for a cure. Reconstructive surgery (B) is typically done to restore form or function, which is not the primary goal in this case. Salvage surgery (C) is usually performed to rescue a situation where initial treatment has failed, which is not the case here. Prophylactic surgery (D) is preventive and is not appropriate in a situation where cancer is already present and advanced.

Correct Answer: B

Rationale: The correct answer is B because injecting air into the stomach via the tube and auscultating helps confirm the tube placement in the stomach before administering the feeding. This step ensures the safety of the patient by preventing accidental lung feeding. Choice A is incorrect because securing the tube with a safety pin to the gown is not a standard practice and can lead to complications. Choice C is incorrect because the temperature of the feeding does not affect the tube placement or safety. Choice D is incorrect because checking the pH level is not a reliable method for verifying tube placement.

Correct Answer: A

Rationale: The correct answer is A. Recording times when the patient is incontinent is crucial in identifying patterns and establishing a structured bowel training program. This data helps in determining the optimal timing for toileting. Choices B, C, and D are incorrect. Choice B is not specific to bowel training and may not address the patient's individual needs. Choice C is not a recommended posture for effective bowel elimination. Choice D, while important for overall health, is not directly related to bowel training.

Correct Answer: D

Rationale: The correct answer is D. The plausible conclusion the nurse should draw is that the patient has not achieved the desired learning outcomes. 1. The patient's repeated questions indicate a lack of understanding despite the nurse's teaching efforts. 2. This suggests that the patient has not grasped the information provided. 3. It does not necessarily mean the patient is not listening effectively, noncompliant, or has low intelligence. 4. The focus should be on reassessing the teaching methods and providing additional support to help the patient achieve the desired learning outcomes.

Correct Answer: B

Rationale: The correct answer is B: Constipation. When a patient is receiving opioids, constipation is a common side effect due to decreased gut motility. It is a priority assessment because untreated constipation can lead to serious complications such as bowel obstruction. Monitoring for constipation allows for early intervention with stool softeners or laxatives to prevent complications. Incorrect choices: A: Clostridium difficile - While important to consider in patients on antibiotics, it is not directly related to opioid use. C: Hemorrhoids - Although opioids can contribute to constipation which may exacerbate hemorrhoids, it is not the priority assessment. D: Diarrhea - Opioids typically cause constipation, so diarrhea is less likely to be a priority concern in this scenario.
