1. What stimulates bile secretion from the liver to the small intestine?
- A. Pepsin
- B. Salivary Amylase
- C. CCK
- D. Secretin
Correct answer: C
Rationale: Cholecystokinin (CCK) is the hormone that stimulates the release of bile from the gallbladder into the small intestine, aiding in fat digestion. Pepsin is an enzyme in the stomach that breaks down proteins into smaller peptides, not involved in bile secretion. Salivary Amylase is an enzyme in saliva that initiates starch digestion in the mouth, not related to bile secretion. Secretin is a hormone that regulates the release of gastric juice in the stomach and triggers the pancreas to neutralize stomach acid in the small intestine, but it does not stimulate bile secretion.
2. Each of the following accurately describes aspects of the dietary reference intakes (DRIs) published by the Food and Nutrition Board of the Institute of Medicine (IOM) except one. Which one is the exception?
- A. The DRIs replace the older recommended daily allowances.
- B. Current DRIs attempt to estimate required nutrients to improve long-term health.
- C. DRIs specifically address individuals whose requirements are affected by a disease state.
- D. The DRIs attempt to establish maximum safe levels of tolerance for nutrients.
Correct answer: C
Rationale: The correct answer is C. DRIs do not specifically address individuals with disease states; they are intended for the general healthy population. Choice A is correct because DRIs indeed replace the older recommended daily allowances. Choice B is correct as current DRIs aim to estimate required nutrients to enhance long-term health. Choice D is accurate as DRIs also attempt to establish maximum safe levels of tolerance for nutrients.
3. Which consumption pattern of fermentable carbohydrate is considered most cariogenic?
- A. A single exposure to a large quantity
- B. A single exposure to a small quantity
- C. Multiple exposures of small quantities
- D. Multiple exposures followed by chewing sugarless gum
Correct answer: C
Rationale: Multiple exposures of small quantities are considered most cariogenic. The total amount of dietary fermentable carbohydrate seems to matter less than the form and frequency in which it is consumed. Having multiple exposures of even small quantities of fermentable carbohydrate throughout the day promotes a highly cariogenic environment in the mouth. Choices A and B, involving single exposures, are less cariogenic as they do not sustain the fermentation process over time. Choice D suggests a beneficial practice by chewing sugarless gum after exposures, which can reduce the risk, making it less cariogenic compared to multiple exposures of small quantities.
4. All of the following are seen in a child with measles. Which one is not?
- A. Reddened eyes
- B. Coryza
- C. Pustule
- D. Cough
Correct answer: C
Rationale: Measles typically presents with symptoms like reddened eyes, coryza (inflammation of the mucous membrane in the nose), and cough. However, pustules are not a common symptom of measles. Pustules are more characteristic of conditions like chickenpox rather than measles. Understanding these distinctions is crucial for accurate diagnosis and appropriate treatment.
5. A nurse is providing discharge teaching about food choices to a client who has hypokalemia. Which of the following foods should the nurse identify as the best source of potassium?
- A. 1 cup grapes
- B. 1 cup shredded lettuce
- C. 1 cup cooked tomatoes
- D. 1 cup apple slices
Correct answer: C
Rationale: Cooked tomatoes are high in potassium, which is crucial for maintaining normal cell function, nerve transmission, and muscle contraction, making them a suitable choice for addressing hypokalemia. Grapes, shredded lettuce, and apple slices do not contain as much potassium as cooked tomatoes, so they are not the best choice for addressing hypokalemia.
