Multiple Choice Questions on Gastrointestinal Disorders Questions
Question 1 of 5
Regarding HCL:
Correct Answer: B
Rationale: Step 1: HCL helps in the digestion of food by creating an acidic environment in the stomach. Step 2: This acidic environment aids in the breakdown of food components, including iron. Step 3: Iron absorption is enhanced in the presence of HCL. Conclusion: Choice B is correct as HCL helps in the absorption of iron. Choices A, C, and D are incorrect as HCL does not inhibit pepsinogen, aid in absorption of vitamin B12, or secreted in response to sympathetic stimulation.
Question 2 of 5
Which enzyme is responsible for the breakdown of carbohydrates in the mouth during the process of digestion?
Correct Answer: A
Rationale: The correct answer is A: Amylase. Amylase is responsible for breaking down carbohydrates in the mouth during digestion. It is produced in the salivary glands and helps to break down complex carbohydrates into simpler sugars like maltose. Lipase (B) breaks down fats, pepsin (C) breaks down proteins, and trypsin (D) is an enzyme that also breaks down proteins but is produced in the pancreas, not in the mouth. Amylase is the only enzyme among the choices that specifically targets carbohydrates in the mouth, making it the correct answer.
Question 3 of 5
A patient's peripheral parenteral nutrition (PN) bag is nearly empty, and a new PN bag has not arrived yet from the pharmacy. Which intervention by the nurse is appropriate?
Correct Answer: B
Rationale: Correct Answer: B Rationale: 1. Infusing 5% dextrose in water will provide the patient with necessary calories and prevent hypoglycemia until the new PN bag arrives. 2. Dextrose infusion will help maintain glucose levels and prevent metabolic complications. 3. Monitoring capillary blood glucose every 6 hours (Choice A) may not provide immediate support to prevent hypoglycemia. 4. Decreasing the PN infusion rate (Choice D) may lead to inadequate nutrition and compromise patient's metabolic needs.
Question 4 of 5
Which information in this male patient's electronic health record as shown in the accompanying figure will the nurse use to confirm that the patient has metabolic syndrome? (Select all that apply.)
Correct Answer: B
Rationale: The correct answer is B: Waist size. The nurse can confirm metabolic syndrome by assessing waist size as it is a key component in diagnosing the condition. Metabolic syndrome is characterized by central obesity, which is reflected in an increased waist circumference. The other choices, weight (A), blood glucose (C), and blood pressure (D), may provide valuable information in assessing the patient's overall health but are not specific indicators of metabolic syndrome. Weight alone does not necessarily indicate central obesity, blood glucose may be elevated due to other reasons, and blood pressure can be affected by various factors unrelated to metabolic syndrome. Therefore, waist size is the most relevant measure to confirm the presence of metabolic syndrome in this case.
Question 5 of 5
The term wisdom tooth refers to the _____ tooth.
Correct Answer: B
Rationale: The correct answer is B: third molar. Wisdom teeth are the third molars located at the back of the mouth. They typically erupt in late teens or early twenties. Incisors (A) are front teeth for cutting, second bicuspids (C) help with chewing, and first cuspids (D) are also known as canines for tearing food. The key is understanding dental anatomy and the specific location/function of each tooth type.
