Nutrition Final Exam
1. What is an important nursing intervention for a child with a newly inserted central venous catheter?
- A. Regularly monitor for signs of infection
- B. Administer intravenous fluids only as ordered
- C. Restrict the child's movement
- D. Perform daily dressing changes only
Correct answer: A
Rationale: Regularly monitoring for signs of infection is a critical nursing intervention for a child with a newly inserted central venous catheter. This intervention is essential to detect any early signs of infection, such as redness, swelling, or drainage at the catheter site, which can lead to serious complications like sepsis. Administering intravenous fluids as ordered is important but not the most crucial intervention for a newly inserted central venous catheter. Restricting the child's movement is unnecessary unless specified by the healthcare provider. Performing daily dressing changes alone is not sufficient to ensure the catheter's integrity and the child's safety; monitoring for signs of infection is key.
2. What is one function of water in the human body?
- A. Water provides calories for energy.
- B. Water helps transport nutrients and waste products.
- C. Water acts as a solvent for many biological reactions.
- D. Water maintains body temperature.
Correct answer: B
Rationale: The correct answer is B: Water helps transport nutrients and waste products. Water plays a crucial role in the body by aiding in the transportation of essential nutrients to cells and removing waste products. While water is essential for various metabolic processes, it does not provide calories for energy (choice A). Although water can act as a solvent for biological reactions (choice C), its primary function is not as a solvent. Additionally, while water does help in regulating body temperature to some extent, its main role is not to maintain body temperature (choice D).
3. You have been asked to help a top nutrition researcher conduct human experiments on vitamin C. As the subjects walk into the laboratory, you distribute all the vitamin C pill bottles to the girls and all the placebo pill bottles to the boys. What should you have done?
- A. Giving all the boys the vitamin C and the girls the placebo, and telling them what they were getting.
- B. Distributing the bottles randomly, randomizing the subjects, and telling them what they were getting.
- C. Telling the subjects which group they were in, but preventing yourself from knowing the contents of the pill bottles.
- D. Preventing yourself from knowing what is in the pill bottles, and distributing the bottles randomly to the subjects.
Correct answer: D
Rationale: The correct approach in a scientific experiment is to prevent yourself from knowing the contents of the pill bottles and distribute them randomly to the subjects. This randomization helps to avoid bias and ensures that the results are not influenced by preconceived notions. Option A is incorrect because it introduces gender bias by assigning pills based on gender. Option B is incorrect as it mentions telling the subjects what they are getting, which could lead to placebo effects. Option C is incorrect as it suggests disclosing group information to the subjects, which can also introduce bias.
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 a common sign of a respiratory infection in infants?
- A. Increased appetite
- B. Rapid breathing
- C. Decreased urine output
- D. Lethargy
Correct answer: B
Rationale: Rapid breathing is a common sign of a respiratory infection in infants. When infants have a respiratory infection, their breathing may become rapid as their body tries to get more oxygen. This symptom is often seen alongside cough and fever. Increased appetite (Choice A) is not typically associated with respiratory infections but can be seen in other conditions. Decreased urine output (Choice C) is more indicative of dehydration or kidney issues rather than a respiratory infection. Lethargy (Choice D) can be a symptom of various illnesses but is not as specific to respiratory infections as rapid breathing.
