1. 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.
2. The small intestine is comprised of the cecum, colon, and rectum. The large intestine includes the duodenum, jejunum, and ileum.
- A. Both statements are true
- B. Both statements are false
- C. The first statement is true; the second is false
- D. The first statement is false; the second is true
Correct answer: B
Rationale: Both statements are false. The small intestine consists of the duodenum, jejunum, and ileum, while the large intestine includes the cecum, colon, and rectum.
3. 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 are intended for the general population and do not specifically address disease states, which are managed with different clinical guidelines. Choice A is correct as DRIs have replaced the older recommended daily allowances. Choice B is correct as current DRIs aim to estimate the required nutrients for long-term health. Choice D is correct as DRIs also attempt to establish maximum safe levels of tolerance for nutrients.
4. Which breakfast items indicate an understanding of foods high in antioxidants A and C?
- A. Fried eggs, sausage, and whole wheat toast
- B. Oatmeal with blueberries and coffee
- C. Cereal with strawberries and low-fat milk
- D. Hard-boiled eggs, cantaloupe, and orange juice
Correct answer: D
Rationale: The correct answer is D: Hard-boiled eggs, cantaloupe, and orange juice. Cantaloupe and orange juice are rich in vitamins A and C, which are known for their antioxidant properties. Choice A is incorrect because fried eggs, sausage, and whole wheat toast do not contain high levels of antioxidants A and C. Choice B is incorrect because, while blueberries are high in antioxidants, coffee does not provide significant amounts of vitamins A and C. Choice C is incorrect because, although strawberries are a good source of vitamin C, low-fat milk does not contribute significantly to vitamins A and C.
5. Which medical problem is not generally associated with malnutrition?
- A. incontinence
- B. pressure sores
- C. celiac disease
- D. major surgery
Correct answer: A
Rationale: Incontinence is not typically associated with malnutrition, whereas conditions like pressure sores and celiac disease are directly linked to nutritional deficiencies and malabsorption.
