LPN Nutrition Practice Test
1. What action should be taken for a 2-year-old with laryngotracheobronchitis in an oxygen tent?
- A. Restrain the child and notify the healthcare provider
- B. Increase the oxygen concentration
- C. Take the child to the playroom
- D. Ask the mother to help in comforting the child
Correct answer: B
Rationale: In laryngotracheobronchitis (croup), a child may become restless due to poor oxygenation. Increasing the oxygen concentration in the oxygen tent is crucial to improve oxygenation levels and manage symptoms effectively. Restraint is not appropriate in this situation, as it may cause distress and worsen the child's condition. Taking the child to the playroom is not indicated when the child requires oxygen therapy. While comforting the child is important, the priority in this scenario is to optimize oxygen delivery to improve respiratory distress.
2. What is the smallest amount of a nutrient that, when consumed over a prolonged period, maintains a specific function?
- A. nutrient allowance
- B. nutrient requirement
- C. nutrient tolerable limit
- D. nutrient adequate intake
Correct answer: B
Rationale: The correct answer is 'B: nutrient requirement.' The nutrient requirement refers to the smallest amount of a nutrient that, when consumed over a prolonged period, maintains a specific function in the body. This amount ensures the body's optimal functioning and health. Choice A, 'nutrient allowance,' is incorrect as it does not specifically refer to the minimum amount needed for bodily functions but rather suggests a broader term. Choice C, 'nutrient tolerable limit,' is incorrect as it pertains to the maximum amount of a nutrient that can be consumed without adverse effects. Choice D, 'nutrient adequate intake,' is incorrect as it refers to the recommended average daily intake level of a nutrient to meet the requirements of most healthy individuals.
3. What is a key aspect of managing a child with eczema?
- A. Daily baths with soap
- B. Regular use of emollients and moisturizers
- C. High-protein diet
- D. Frequent exposure to sunlight
Correct answer: B
Rationale: Regular use of emollients and moisturizers is a key aspect of managing eczema in children. Emollients help maintain skin hydration and reduce irritation, which are crucial in managing eczema symptoms. Daily baths with soap can actually worsen eczema by drying out the skin further. A high-protein diet and frequent exposure to sunlight are not directly related to managing eczema and may not have a significant impact on the condition.
4. What is a common sign of iron-deficiency anemia in children?
- A. Yellowing of the skin
- B. Pallor and fatigue
- C. Rapid weight gain
- D. Increased appetite
Correct answer: B
Rationale: Pallor and fatigue are common signs of iron-deficiency anemia in children. Iron-deficiency anemia is characterized by a decreased production of red blood cells, leading to a paler appearance (pallor) and increased fatigue due to reduced oxygen-carrying capacity. Yellowing of the skin (choice A) is more commonly associated with liver or bile duct issues. Rapid weight gain (choice C) and increased appetite (choice D) are not typical signs of iron-deficiency anemia.
5. How does a double-blind experiment work?
- A. Both subject groups take turns receiving each treatment.
- B. Neither subjects nor researchers know which subjects are in the control or experimental group.
- C. Neither group of subjects knows whether they are in the control or experimental group, but the researchers do not know.
- D. Both subject groups know whether they are in the control or experimental group, but the researchers do not know.
Correct answer: B
Rationale: The correct answer is B. In a double-blind experiment, neither the subjects nor the researchers know which subjects are in the control or experimental group. This helps to eliminate bias and ensure that the results are more objective. Choice A is incorrect as in a double-blind experiment, subjects do not take turns receiving each treatment; it is about masking the treatment allocation. Choice C is incorrect because it implies that the researchers are aware of the group allocation, which goes against the principle of blinding in a double-blind study. Choice D is incorrect as both subject groups should not know whether they are in the control or experimental group to maintain the blindness of the study.
