Gastrointestinal Questions Questions
Question 1 of 5
The frenulum is the membrane attached to the inferior surface of the _____.
Correct Answer: A
Rationale: The correct answer is A: tongue. The frenulum is a small fold of tissue that connects the tongue to the floor of the mouth. This attachment helps with the movement and function of the tongue during activities such as speaking and eating. Choices B, C, and D are incorrect because the frenulum is not associated with the stomach, lips, or liver in the human anatomy. The specific location and function of the frenulum on the tongue make choice A the correct answer in this context.
Question 2 of 5
Which of these is a water soluble vitamin?
Correct Answer: B
Rationale: Step 1: Water-soluble vitamins dissolve in water, are not stored in the body, and need to be replenished daily. Step 2: Vitamin C fits these criteria as it dissolves in water, is not stored in the body, and needs daily intake. Step 3: Vitamin D, E, and K are fat-soluble vitamins, stored in the body, and do not need daily replenishment. Summary: Choice B (Vitamin C) is the correct answer as it is water-soluble, while choices A (Vitamin D), C (Vitamin E), and D (Vitamin K) are fat-soluble vitamins and do not meet the criteria of water solubility.
Question 3 of 5
Which enzyme is responsible for the digestion of carbohydrates?
Correct Answer: C
Rationale: The correct answer is C: amylase. Amylase is an enzyme that specifically breaks down carbohydrates into simple sugars like glucose. It is produced in the salivary glands and pancreas, aiding in the digestion process. Lipase (choice A) digests fats, pepsin (choice B) digests proteins, and trypsin (choice D) also digests proteins in the small intestine. However, amylase is the only enzyme responsible for the digestion of carbohydrates, making it the correct choice in this scenario.
Question 4 of 5
A nurse is providing instructions for a 52-year-old client who is scheduled for a colonoscopy. The client reports that he has not had the procedure before and is very anxious about feeling pain during the procedure. Which of the following responses by the nurse is appropriate?
Correct Answer: B
Rationale: The correct answer is B because administering a sedative before the colonoscopy will help the client relax and reduce anxiety. Sedatives are commonly used to ensure the client is comfortable during the procedure. This approach addresses the client's fear of feeling pain and helps ensure a successful and tolerable experience. Choice A is incorrect because dismissing the client's concerns may increase anxiety. Choice C is incorrect as it does not offer a solution to alleviate the client's anxiety. Choice D is also incorrect because discussing the procedure after signing the consent form may not address the client's immediate anxiety about pain during the procedure.
Question 5 of 5
A nurse in a PACU is assessing a client who has a newly created colostomy. Which of the following findings should the nurse report to the provider?
Correct Answer: C
Rationale: The correct answer is C: Purplish-colored stoma. A purplish-colored stoma may indicate inadequate blood supply to the area, which is a sign of ischemia and can lead to tissue necrosis. This is a critical finding that requires immediate intervention to prevent further complications. A: Stoma oozing red drainage is a common finding in the immediate postoperative period and is not typically concerning unless it is excessive or accompanied by other symptoms. B: A shiny, moist stoma is a healthy stoma appearance, indicating good blood supply and hydration. D: A rosebud-like stoma orifice is a normal finding and not typically concerning unless there are signs of infection or other complications.
