Correct Answer: C

Rationale: For an oral cholecystogram, the client should eat a fat-free meal the evening before the procedure and avoid oral intake except for water on the day of the procedure. During the test, the client may be given a high-fat meal or drink to stimulate gallbladder emptying. Choice A is incorrect because the client should have a fat-free meal, not a high-fat meal. Choice B is incorrect as strict NPO status is not required. Choice D is incorrect as a high-fat meal is not recommended for breakfast on the day of the procedure.

Correct Answer: B

Rationale: Common signs of acute viral hepatitis include weight loss, dark urine, and fatigue. The client is anorexic, possibly from a toxin produced by the diseased liver, and finds food distasteful. The urine darkens because of excess bilirubin being excreted by the kidneys. Fatigue occurs during all phases of hepatitis.

Correct Answer: A

Rationale: The correct answer is A: increasing fluid intake to prevent dehydration. An ileostomy typically drains liquid waste, so the client is at risk of fluid loss. By increasing fluid intake, the client can prevent dehydration. It's essential for the client to wear a collection appliance at all times because ileostomy drainage is incontinent. Consuming a low-protein, high-fiber diet is not recommended as high-fiber foods can cause intestinal irritation. Enteric-coated medications should be avoided because they may not be absorbed properly after an ileostomy.

Correct Answer: B

Rationale: An abdominal ultrasound is the most commonly used test to diagnose cholecystitis.

Correct Answer: C

Rationale: The correct answer is C, 'Barium swallow.' A barium swallow should be done after a barium enema or gallbladder series to prevent the contrast used in the barium swallow from obstructing the view of other organs. It takes several days for swallowed barium to pass completely out of the gastrointestinal tract. Choices A, B, and D are incorrect because a barium swallow should be the last test performed to ensure clear imaging without interference from residual contrast material.
