1. Which of the following converts starch to disaccharides, and this reaction occurs in the _____?
- A. pancreatic amylases, small intestine
- B. brush border enzymes, small intestine
- C. luminal enzymes, large intestine
- D. pancreatic amylases, pancreas
Correct answer: A
Rationale: The correct answer is A. Pancreatic amylases break down starch into disaccharides in the small intestine. This process occurs in the small intestine, not the large intestine or pancreas. Brush border enzymes act on disaccharides to break them down into monosaccharides, while luminal enzymes are not specifically involved in the conversion of starch to disaccharides.
2. Which of the following is a tricyclic antidepressant drug?
- A. Venlafaxine (Effexor)
- B. Fluoxetine (Prozac)
- C. Sertraline (Zoloft)
- D. Imipramine (Tofranil)
Correct answer: D: Imipramine (Tofranil)
Rationale: Imipramine (Tofranil) is a tricyclic antidepressant drug. This class of medications is used to treat depression, and they work by increasing the levels of certain chemicals in the brain that help lift mood. On the other hand, Venlafaxine (Effexor) is a serotonin and norepinephrine reuptake inhibitor (SNRI), Fluoxetine (Prozac) is a selective serotonin reuptake inhibitor (SSRI), and Sertraline (Zoloft) is also an SSRI. Therefore, they are not classified as tricyclic antidepressants.
3. The purpose of chest percussion and vibration is to loosen secretions in the lungs. The difference between the procedures is:
- A. Percussion uses only one hand, while vibration uses both hands
- B. Percussion delivers cushioned blows to the chest with cupped palms, while vibration gently shakes secretions loose
- C. In both percussion and vibration, the hands are not on top of each other, and hand action is not in tune with the client's breath
- D. Percussion slaps the chest to loosen secretions, while vibration shakes the secretions along with the inhalation
Correct answer: D
Rationale: Chest percussion involves the use of rhythmic tapping to dislodge mucus from the lungs, facilitating its movement toward the larger airways where it can be expelled. This technique is particularly important in conditions where mucus retention is a significant risk factor for infection. The key difference between chest percussion and vibration is that percussion involves slapping the chest to loosen secretions, while vibration involves shaking the secretions along with the inhalation, aiding in moving the loosened secretions upwards for easier removal. Choices A, B, and C do not accurately describe the main difference between chest percussion and vibration, making them incorrect.
4. What is the most significant dietary influence on the development of dental caries?
- A. Carbohydrates
- B. Vitamins
- C. Minerals
- D. Fats
Correct answer: A
Rationale: The correct answer is A: Carbohydrates. Carbohydrates, especially fermentable sugars, are the most significant dietary factor in the development of dental caries. When these sugars are consumed, they can be fermented by bacteria in the mouth, leading to the production of acids. These acids lower the pH in the mouth, creating an acidic environment that promotes demineralization of the tooth enamel, ultimately causing dental caries. Choices B, C, and D are incorrect because while vitamins and minerals are important for overall health, they do not have the same direct impact on the development of dental caries as fermentable carbohydrates do. Fats, on the other hand, do not play a significant role in the development of dental caries.
5. Which adolescent student lunch, evaluated by the school nurse, is the least nutritious?
- A. Ham sandwich, apple, and milk
- B. Hamburger, fries, and soft drink
- C. Macaroni and cheese, green beans, and peaches
- D. Meatloaf, broccoli, and pear slices
Correct answer: B: Hamburger, fries, and soft drink
Rationale: The correct answer is B: Hamburger, fries, and soft drink. This meal is considered the least nutritious among the options provided due to its high content of unhealthy fats, processed carbohydrates, and added sugars, which lack essential nutrients. On the other hand, choice A: Ham sandwich, apple, and milk, offers a balanced meal with protein, fiber, vitamins, and calcium. Choice C: Macaroni and cheese, green beans, and peaches, provides a mixture of carbohydrates, vegetables, and fruits. Choice D: Meatloaf, broccoli, and pear slices, includes protein, fiber, and vitamins. Thus, all choices except B provide a more balanced and nutritious meal.
