The patient with suspected gallbladder disease is scheduled for an ultrasound of the gallbladder. What should the nurse explain to the patient about this test?

Correct Answer: A

Rationale: The correct answer is A) It is noninvasive and is a very reliable method of detecting gallstones. Rationale: Ultrasound of the gallbladder is a common diagnostic test for gallbladder disease because it is noninvasive, painless, and highly effective in identifying gallstones. It uses high-frequency sound waves to create images of the gallbladder, allowing healthcare providers to visualize the presence of stones. This method is preferred over other imaging techniques like CT scans or MRIs due to its accuracy and safety. Option B) is incorrect because ultrasound is not limited to cases where other tests are contraindicated. Option C) is incorrect as ultrasound primarily focuses on identifying gallstones rather than outlining the entire ductal system. Option D) is incorrect as ultrasound is used for direct visualization rather than assessing inflammation through liver function tests. Educational Context: Understanding the diagnostic procedures for gallbladder disease is crucial for nurses caring for patients with suspected conditions. Educating patients about the purpose, process, and benefits of ultrasound helps alleviate anxiety and promotes patient cooperation. Nurses play a key role in ensuring that patients are well-informed about their healthcare journey, including the rationale behind specific tests and procedures.

Correct Answer: D

Rationale: The correct answer is D: visceral peritoneum. The visceral peritoneum covers the stomach and is a serous membrane that covers the organs within the abdominal cavity. It provides support and protection to the stomach. The falciform ligament (choice A) attaches the liver to the anterior abdominal wall and doesn't cover the stomach. The mesocolon (choice B) is a peritoneal fold that supports the colon, not the stomach. The parietal peritoneum (choice C) lines the abdominal wall and does not cover the stomach directly. Therefore, the correct choice is D because the visceral peritoneum directly covers and protects the stomach.

Correct Answer: B

Rationale: The correct answer is B because obesity can indeed contribute to complications like osteoarthritis due to increased pressure on the joints. This is supported by research showing a link between obesity and joint issues. Choice A is incorrect as obesity can have various causes beyond excessive eating. Choice C is incorrect as metabolism can vary among older adults, and obesity remains a concern regardless. Choice D is incorrect as obesity tends to be a persistent issue that requires management rather than resolving with age.

Correct Answer: A

Rationale: The correct answer is A because MRI provides better contrast between normal and pathologic tissue compared to CT scans. This is crucial for accurately diagnosing certain conditions. Choice B is incorrect as MRI images often require more complex analysis. Choice C is incorrect as both MRI and CT scans can produce digital images. Choice D is incorrect because CT scans expose patients to less radiation than MRI.

Correct Answer: B

Rationale: The correct answer is B: small intestine. The majority of chemical digestion occurs in the small intestine, specifically in the duodenum, where enzymes from the pancreas and bile from the liver break down food into nutrients. Stomach primarily performs mechanical digestion and initial protein breakdown. Mouth initiates mechanical digestion through chewing and begins carbohydrate digestion. Large intestine mainly absorbs water and electrolytes. Therefore, small intestine is the site of most chemical digestion due to its specialized enzymes and processes.
