Which of the following is the transporter for fructose in the small intestine?

Correct Answer: D

Rationale: The correct answer is D: GLUT5. GLUT5 is the specific transporter responsible for transporting fructose across the apical membrane of enterocytes in the small intestine. It is a uniporter that facilitates the movement of fructose down its concentration gradient via facilitated diffusion. SGLT1 (Choice A) and SGLT2 (Choice B) are sodium-glucose transporters involved in the absorption of glucose and galactose, not fructose. GLUT4 (Choice C) is primarily found in muscle and adipose tissue and is responsible for insulin-mediated glucose uptake, not fructose transport in the small intestine.

Correct Answer: D

Rationale: The correct answer is D. A board-like abdomen with shoulder pain indicates a perforated ulcer, a medical emergency requiring immediate intervention. A perforation can lead to peritonitis and septic shock. Choice A, projectile vomiting, may indicate a gastric outlet obstruction but is not as immediately life-threatening as a perforation. Choice B, burning sensation 2 hours after eating, is a common symptom of peptic ulcer disease and does not indicate a complication. Choice C, coffee-ground emesis, may indicate bleeding but is not as severe as a perforation.

Correct Answer: C

Rationale: The correct instruction for a client scheduled for a gallbladder series test is not to eat or drink until the test is complete. This is because the test requires fasting to ensure clear visualization of the gallbladder and surrounding structures. Eating or drinking could interfere with the results by causing gallbladder contraction or obscuring the images. A) Instructing the client to remain on a low-residue diet is not necessary for this specific test and may not provide the required fasting. B) Taking a laxative or cleansing enemas is not typically required for a gallbladder series test and can be unnecessary and may even be harmful.

Correct Answer: D

Rationale: The correct answer is D because smoking can lead to chronic coughing and sneezing, which may increase intra-abdominal pressure. This can be detrimental post-surgery, especially in herniation cases where increased pressure can strain the surgical site, leading to complications like wound dehiscence or hernia recurrence. Choices A and B are incorrect as they do not directly relate to the impact of smoking on intra-abdominal pressure. Choice C is also incorrect as it focuses on medication contraindications rather than the physiological effects of smoking on surgical outcomes.

Correct Answer: B

Rationale: The correct answer is B: Colostomy. A colostomy is an opening in the large bowel created by bringing a section of the large intestine out to the abdomen to form a stoma. This procedure is typically done to divert stool in cases of colorectal diseases or surgeries. A: Continent ileostomy - This choice is incorrect because a continent ileostomy involves creating a pouch inside the body to collect waste, rather than bringing a section of the large intestine out to the abdomen. C: Ileostomy - This choice is incorrect because an ileostomy involves bringing the end of the small intestine out to the abdomen to create a stoma, not a section of the large intestine. D: Ileoanal reservoir - This choice is incorrect as it refers to a surgical procedure where the colon and rectum are removed, and a pouch is created from the small intestine to restore bowel function, not to create a stoma in the large bowel.
