LPN Nutrition Practice Test
1. A child develops a strong dislike of noodle soup after consuming a bowl while sick with the flu. Her reaction is an example of a food-related ___.
- A. habit
- B. social interaction
- C. emotional turmoil
- D. negative association
Correct answer: D
Rationale: The correct answer is 'negative association.' A negative association occurs when a person develops a dislike for a food due to a past negative experience, such as getting sick after eating it. In this case, the child's dislike of noodle soup is specifically linked to the negative experience of consuming it while sick with the flu. Choices A, B, and C are incorrect because the situation described does not relate to habit formation, social interactions, or emotional turmoil, but rather to a learned aversion based on a specific negative event.
2. An essential nutrient is one that ___
- A. must be made in large quantities by the body
- B. can only be synthesized by the body
- C. cannot be made in sufficient quantities by the body
- D. is used to synthesize other compounds in the body
Correct answer: C
Rationale: An essential nutrient is a substance that cannot be made in sufficient quantities by the body itself, so it must be obtained from the diet. Choice A is incorrect because essential nutrients are required in specific amounts, not necessarily large quantities. Choice B is incorrect as essential nutrients cannot be synthesized by the body at all. Choice D is incorrect because although essential nutrients may be used in the synthesis of other compounds, that is not the defining characteristic of an essential nutrient.
3. 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.
4. How should a healthcare professional manage a child with scabies?
- A. Use topical permethrin cream
- B. Administer oral antibiotics
- C. Apply topical antifungals
- D. Provide supportive care only
Correct answer: A
Rationale: Corrected Rationale: Topical permethrin cream is the appropriate treatment for scabies as it effectively kills the mites causing the infestation. Oral antibiotics are not indicated for scabies as it is not a bacterial infection. Topical antifungals are used to treat fungal infections, not scabies. Providing supportive care only would not address the underlying cause of scabies, which is the mite infestation.
5. When an increase in exercise is accompanied by a decrease in body weight, it is an example of what?
- A. variable effect
- B. positive correlation
- C. negative correlation
- D. randomization effect
Correct answer: C
Rationale: When an increase in exercise is accompanied by a decrease in body weight, it demonstrates a negative correlation. This means that as one variable (exercise) increases, the other variable (body weight) decreases. Choice A, 'variable effect,' is vague and does not accurately describe the relationship between exercise and body weight. Choice B, 'positive correlation,' is incorrect because in a positive correlation, both variables would increase or decrease together. Choice D, 'randomization effect,' is unrelated to the scenario described.
