Nutrition Final Exam Quizlet
1. What does a positive correlation between two variables indicate?
- A. One variable causes the other.
- B. Both variables move in the same direction.
- C. Both variables move in opposite directions.
- D. There is no relationship between the variables.
Correct answer: B
Rationale: A positive correlation between two variables indicates that they move in the same direction. This means that as one variable increases (or decreases), the other variable also increases (or decreases). Choice A is incorrect because correlation does not imply causation; it only shows a relationship between variables. Choice C is incorrect as it describes a negative correlation where variables move in opposite directions. Choice D is incorrect as a positive correlation implies a relationship between the variables.
2. What is the primary goal in managing a child with asthma?
- A. Prevent triggering asthma attacks
- B. Avoid triggering asthma attacks
- C. Administer corticosteroids
- D. Increase physical activity
Correct answer: B
Rationale: The primary goal in managing a child with asthma is to avoid triggering asthma attacks. This involves managing allergens, ensuring proper medication use, and creating an asthma action plan. Choice A is incorrect because the goal is to avoid triggering asthma attacks, not necessarily to prevent recurrent infections. Choice C is incorrect as corticosteroids are a treatment option but not the primary goal of asthma management. Choice D is incorrect because although physical activity is important, the primary goal is to prevent asthma attacks and manage symptoms effectively.
3. What should be assessed in an infant diagnosed with hypertrophic pyloric stenosis?
- A. Diarrhea after each feeding
- B. Gastric pain and vigorous crying
- C. Poor appetite due to poor sucking reflex
- D. An olive-shaped mass right of the midline
Correct answer: D
Rationale: In hypertrophic pyloric stenosis, an olive-shaped mass can often be palpated in the infant's abdomen, which is a hallmark sign of this condition. This mass is located in the right upper quadrant of the abdomen, right of the midline. Choices A, B, and C are incorrect because while infants with hypertrophic pyloric stenosis may experience vomiting (not diarrhea), gastric pain, and irritability, and have feeding difficulties, the key assessment finding specific to this condition is the palpable olive-shaped mass in the abdomen.
4. What does the term 'essential nutrient' refer to?
- A. A nutrient that can be synthesized by the body.
- B. A nutrient that is required for proper body functioning.
- C. A nutrient that must be obtained from the diet because the body cannot produce it.
- D. A nutrient that can be stored in the body for long periods.
Correct answer: C
Rationale: The correct answer is C. An essential nutrient is a substance that is necessary for normal body functioning but cannot be synthesized in adequate amounts by the body, therefore it must be obtained from the diet. Choices A, B, and D are incorrect because essential nutrients are not synthesized by the body, they are necessary for body functioning, and they are not typically stored in the body for long periods.
5. What is the key to preventing recurrent respiratory infections in children with cystic fibrosis?
- A. Routine use of antibiotics
- B. Daily chest physiotherapy
- C. Increased fluid intake
- D. Dietary supplements
Correct answer: B
Rationale: The correct answer is B: Daily chest physiotherapy. Daily chest physiotherapy is essential in cystic fibrosis as it helps in clearing mucus from the lungs, reducing the frequency of respiratory infections. Antibiotics (Choice A) may treat infections but are not the key preventive measure. Increased fluid intake (Choice C) and dietary supplements (Choice D) can be beneficial for overall health but do not directly prevent recurrent respiratory infections in children with cystic fibrosis.
