What risk factor will the nurse specifically ask about when a patient is being admitted with acute pancreatitis?

Correct Answer: B

Rationale: The correct answer is B: Alcohol use. Alcohol is a significant risk factor for acute pancreatitis as it can lead to inflammation and damage to the pancreas. The nurse will specifically ask about alcohol use to assess the potential cause of the pancreatitis. Diabetes (A), high-protein diet (C), and cigarette smoking (D) are not typically primary risk factors for acute pancreatitis, although smoking may exacerbate existing conditions. Therefore, the nurse's focus should be on identifying alcohol use as it directly correlates with the development of acute pancreatitis.

Correct Answer: C

Rationale: The correct answer is C: cholecystokinin. It is a hormone released by the small intestine in response to the presence of fat and protein in the digestive tract. Cholecystokinin plays a role in the digestion and absorption of nutrients. Trypsin, ribonuclease, and chymotrypsinogen are enzymes involved in digestion, not hormones. Hormones are chemical messengers produced by glands and released into the bloodstream to regulate various physiological processes in the body.

Correct Answer: A

Rationale: The duodenum has the greatest amount of enzyme activity among the choices given. This is because the duodenum is the first part of the small intestine where most digestion occurs. It receives bile from the liver and pancreatic enzymes, which aid in breaking down food molecules. The colon, jejunum, and ileum are parts of the small intestine but have less enzyme activity compared to the duodenum. The colon mainly absorbs water and electrolytes, while the jejunum and ileum are involved in nutrient absorption rather than enzyme activity. Therefore, the duodenum is the correct choice based on its role in digestion and enzyme secretion.

Correct Answer: B

Rationale: The large intestine is primarily responsible for the absorption of water in the digestive system. It reabsorbs water and electrolytes from the indigestible food residue, forming feces. The small intestine is more involved in nutrient absorption. The stomach mainly digests food, while the duodenum is the initial segment of the small intestine where most digestion occurs. The large intestine's main role in water absorption makes it the correct answer.

Correct Answer: B

Rationale: The correct answer is B: The laxative helps eliminate the barium. After a barium swallow, the client needs to expel the barium from their system to prevent barium toxicity. The laxative helps to move the barium through the digestive system and facilitate its elimination. Choices A, C, and D are incorrect because preventing magnesium absorption, facility protocol, and changing the color of barium are not reasons for the necessity of a laxative after a barium swallow.
