Which of the following routes is used to instill a dye for a radionuclide imaging test?

Correct Answer: A

Rationale: The correct answer is A because instilling a dye for radionuclide imaging test involves injecting the dye intravenously or orally to allow it to circulate in the bloodstream and be absorbed by the body tissues. IV route ensures rapid and direct entry into the bloodstream for proper distribution. Choices B, C, and D are incorrect as they do not provide the necessary direct access to the bloodstream required for effective distribution of the dye for imaging purposes.

Correct Answer: D

Rationale: The correct answer is D: Two hours before a meal. This timing allows for the colon to be relatively empty, making irrigation more effective. Irrigating two hours before a meal helps to prevent interference with digestion and absorption processes. Irrigating after a meal (choice A) or during a meal (choice C) may lead to discomfort, bloating, or potential leakage. Irrigating after a bowel movement (choice B) may not provide enough time for the colon to be adequately empty for effective irrigation.

Correct Answer: A

Rationale: The correct answer is A: Surgery. Surgery increases protein-calorie needs due to the body's increased demand for nutrients to support healing and recovery. The body requires more protein and calories to repair tissues and maintain immune function post-surgery. Choice B: A vegan diet does not necessarily contribute to increased protein-calorie needs as it is possible to meet nutritional requirements with proper planning. Choice C: Lowered temperature does not directly affect protein-calorie needs. Choice D: Cultural or religious beliefs do not inherently increase protein-calorie needs, as dietary choices can still meet nutritional requirements.

Correct Answer: B

Rationale: The correct answer is B: History of untreated depression. Before proceeding with further patient preparation for bariatric surgery, it is crucial to address untreated depression as it can significantly impact the patient's mental and emotional well-being post-operatively. Untreated depression can lead to poor compliance with post-operative instructions, medication management issues, and potentially increase the risk of complications. It is essential to involve the surgeon to assess the patient's psychological readiness for surgery and ensure appropriate support and resources are in place. Incorrect choices: A: History of hypertension - While hypertension should be managed pre-operatively, it is not a critical factor that would require immediate attention before further preparation. C: History of multiple attempts at weight loss - This is a common issue in patients undergoing bariatric surgery and does not pose an immediate risk that needs urgent attention. D: History of sleep apnea treated with CPAP - While sleep apnea is a relevant consideration for bariatric surgery, the fact that it is being treated with

Correct Answer: A

Rationale: The correct answer is A because a 55-year-old female who is a smoker and experiencing symptoms of nausea and vomiting has multiple risk factors for developing a gastric ulcer. Smoking and older age are established risk factors for gastric ulcers. Nausea and vomiting can be indicative of underlying gastrointestinal issues. Choice B is less likely as illicit drug use typically does not directly increase the risk of gastric ulcers. Choice C is less likely as the male falling while looking for a job does not directly relate to gastric ulcer development. Choice D is less likely as divorce and back pain are not direct risk factors for gastric ulcers.
