Correct Answer: A

Rationale: The correct answer is A because cathartics can exacerbate ulcerative colitis symptoms by increasing bowel motility and causing further inflammation. Giving an oil retention enema (choice B) is not necessary for a barium enema. Ingesting radiopaque tablets (choice C) is not typically part of the preparation for a barium enema. Positioning the patient in a high Fowler's position (choice D) is not a specific requirement following the procedure. Overall, avoiding cathartics is crucial in patients with acute ulcerative colitis to prevent worsening of symptoms during the barium enema.

Correct Answer: C

Rationale: Step-by-step rationale: 1. INH (Isoniazid) can lead to peripheral neuropathy due to vitamin B6 deficiency. 2. Pyridoxine is vitamin B6, which helps prevent neuropathy. 3. Supplementing with pyridoxine can counteract the deficiency caused by INH. 4. Thus, option C, supplementing the diet with pyridoxine, is the correct choice. Summary: - Option A is incorrect as a low cholesterol diet does not address the vitamin B6 deficiency. - Option B is incorrect as excessive bed rest does not prevent neuropathy. - Option D is incorrect as sun exposure is not related to the prevention of peripheral neuropathy.

Correct Answer: B

Rationale: The correct answer is B. A semiprivate room with one or two consistent caregivers is the most therapeutic setting for an agitated head-injured patient. Here's the rationale: 1. Consistency: Having one or two consistent caregivers provides the patient with a stable and familiar environment, which can help reduce agitation. 2. Privacy: A semiprivate room offers more privacy compared to a day room or a ward, which can help minimize external stimuli and promote relaxation. 3. Individualized care: In a semiprivate room, caregivers can focus more on the specific needs of the patient, leading to better management of agitation. 4. Reduced distractions: Being in a semiprivate room minimizes distractions and noise, which can be overwhelming for an agitated head-injured patient. Summary: A, C, and D are incorrect because they do not offer the same level of consistency, privacy, individualized care, and reduced distractions as a semiprivate room with one

Correct Answer: C

Rationale: The correct answer is C: Weighing the client before and after the procedure. This is crucial as it helps monitor fluid removal during dialysis, ensuring the process is effective and safe. Weighing helps determine if the correct amount of fluid has been removed. A: Keeping dialysis supplies in a clean area is important for infection control but not a direct responsibility during the procedure. B: Inspecting the catheter insertion site for signs of infection is essential for monitoring the site's health but not a direct responsibility during dialysis. D: Washing hands before and after handling the catheter is a general infection control measure but not specific to the dialysis procedure itself.

Correct Answer: C

Rationale: The correct answer is C: General to specific assessment. In this scenario, the nurse is starting with a broad assessment of the surgical dressing and the type of drainage present, then will progress to more specific assessments based on the findings. This approach allows for a systematic and comprehensive evaluation of the patient's condition by moving from general observations to detailed examinations. Explanation: 1. General assessment: The nurse is initially assessing the overall appearance of the surgical dressing and the type of drainage. 2. Specific assessment: Based on the initial findings, the nurse will proceed to conduct more focused assessments, such as checking for signs of infection, monitoring vital signs, and assessing the surgical site for any complications. Other choices are incorrect: A: Gordon’s Functional Health Patterns - This framework focuses on assessing different aspects of an individual's health patterns, such as activity level, sleep patterns, and coping mechanisms. It is not the most appropriate approach in this situation. B: Activity-exercise pattern assessment - This type of assessment focuses
