LPN Nutrition Practice Test
1. How should a healthcare provider respond to a parent concerned about their child's frequent ear infections?
- A. Recommend over-the-counter ear drops
- B. Suggest an ENT specialist evaluation
- C. Advise on increasing fluid intake
- D. Encourage more physical exercise
Correct answer: B
Rationale: When a parent expresses concerns about their child's frequent ear infections, suggesting an ENT specialist evaluation is the most appropriate response. This specialist can conduct a thorough examination to identify the underlying cause of the recurrent infections and recommend the most suitable treatment. Recommending over-the-counter ear drops (Choice A) may not address the root cause of the issue and could potentially lead to inappropriate treatment. Advising on increasing fluid intake (Choice C) and encouraging more physical exercise (Choice D) are unrelated to addressing the specific concern of frequent ear infections.
2. Which statement best describes the relationship between diet and chronic diseases?
- A. Diet has no impact on chronic diseases.
- B. A poor diet can increase the risk of developing chronic diseases.
- C. Diet is the sole cause of chronic diseases.
- D. A balanced diet can help prevent or manage chronic diseases.
Correct answer: B
Rationale: Choice B is the correct answer. A poor diet can increase the risk of developing chronic diseases due to the lack of essential nutrients or the presence of harmful components like excessive sugar, salt, or saturated fats. While diet plays a significant role in the development of chronic diseases, it is not the sole cause (choice C). Choice A is incorrect because diet does indeed have a significant impact on chronic diseases. Choice D is not the best answer as it does not acknowledge the negative impact of a poor diet on chronic diseases.
3. What is a common symptom of a respiratory infection in infants?
- A. Wheezing
- B. High appetite
- C. Increased thirst
- D. Lethargy
Correct answer: A
Rationale: Wheezing is a common symptom of respiratory infections in infants, often associated with coughing and difficulty breathing. It occurs due to the narrowing of the airways. Choice B, 'High appetite,' is incorrect as respiratory infections usually lead to a decrease in appetite rather than an increase. Choice C, 'Increased thirst,' is incorrect as it is not a typical symptom of a respiratory infection in infants. Choice D, 'Lethargy,' can be a symptom of respiratory infections but is not as specific and common as wheezing.
4. How many vitamins are known to be required in the diet of human beings?
- A. 5
- B. 8
- C. 10
- D. 13
Correct answer: D
Rationale: The correct answer is D: 13. There are 13 essential vitamins required in the diet of human beings, including vitamins A, C, D, E, K, and the B vitamins. Choice A (5), Choice B (8), and Choice C (10) are incorrect because they do not represent the total number of essential vitamins needed by human beings.
5. What is the primary purpose of a placebo in an experiment?
- A. To reduce the cost of the experiment.
- B. To make the experiment double-blind.
- C. To increase the number of participants.
- D. To serve as a control for comparison with the treatment group.
Correct answer: D
Rationale: The correct answer is D. A placebo serves as a control for comparison with the treatment group, helping to eliminate bias and ensure the results are due to the treatment itself. Placebos are crucial in research to distinguish the actual effect of the treatment from psychological or subjective factors. Choice A is incorrect because the purpose of a placebo is not related to reducing the cost of the experiment. Choice B is incorrect because while placebos are used in double-blind studies, their primary purpose is not to make the experiment double-blind. Choice C is incorrect because the purpose of a placebo is not to increase the number of participants but rather to serve as a comparison group for the treatment being tested.
