What is the final product of carbohydrate digestion in the small intestine?

Correct Answer: D

Rationale: The final product of carbohydrate digestion in the small intestine is glucose. Carbohydrates are broken down into simple sugars like glucose during digestion. Enzymes in the small intestine, such as amylase, break down complex carbohydrates into glucose molecules, which can then be absorbed into the bloodstream for energy. Fatty acids (A) are the final product of lipid digestion, while amino acids (B) are the final product of protein digestion. Choice C is irrelevant. In summary, glucose is the correct answer as it is the end product of carbohydrate digestion, while the other choices are related to different types of digestion products.

Correct Answer: A

Rationale: Rationale for Correct Answer (A): The statement "I can take a shower and walk around the house tomorrow" indicates an understanding of post-operative activity expectations. After a laparoscopic cholecystectomy, early ambulation is encouraged to prevent complications like blood clots. Additionally, showering promotes wound healing and hygiene. Incorrect Choices: B: "I need to limit my activities and not return to work for 4 weeks" - This choice is incorrect as it overestimates the recovery time for a laparoscopic cholecystectomy, which typically allows for a quicker return to normal activities. C: "I can expect yellowish drainage from the incision for a few days" - While drainage is common after surgery, the color and duration mentioned are not typical for this procedure. D: "I will follow a low-fat diet for life because I do not have a gallbladder" - Following a low-fat diet is recommended after surgery, but the statement is too extreme as dietary

Correct Answer: B

Rationale: The correct answer is B: palatine tonsils. Palatine tonsils are the most commonly inflamed lymphatic areas due to their location at the back of the throat where they can easily come into contact with pathogens. They play a crucial role in immune defense against infections. Peyer's patches are found in the small intestine and are involved in immune responses to pathogens in the digestive tract. Lingual tonsils are located at the base of the tongue and are less frequently inflamed compared to the palatine tonsils. Adenoids are located in the upper part of the throat behind the nose and are also less commonly inflamed than the palatine tonsils.

Correct Answer: A

Rationale: The correct answer is A: cholecystokinin. Cholecystokinin stimulates the pancreas to secrete an enzyme-rich fluid to aid in digestion in response to the presence of fats and proteins in the small intestine. Secretin mainly stimulates bicarbonate secretion from the pancreas. Enterogastrone inhibits gastric emptying. Enterocrinin stimulates the secretion of digestive enzymes from the pancreas and also helps regulate the movements of the intestine.

Correct Answer: B

Rationale: The correct answer is B: duodenum. The duodenum is the shortest section of the small intestine, measuring around 25-30 cm in length. It is the first part of the small intestine and plays a crucial role in the digestion process by receiving partially digested food from the stomach and mixing it with digestive enzymes from the pancreas and bile from the liver. The colon (choice A) is the longest part of the large intestine, the ileum (choice C) and jejunum (choice D) are longer sections of the small intestine, following the duodenum in the digestive tract. Therefore, the duodenum is the correct answer as it is specifically the shortest part of the intestines.
