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 main function of proteins in the body?
- A. They provide structural components for the body.
- B. They assist in the absorption of vitamins.
- C. They help with the transport of nutrients in the blood.
- D. They help maintain fluid balance in the body.
Correct answer: A
Rationale: The main function of proteins in the body is to provide structural components like muscles, skin, and bones. Proteins are essential for growth, repair, and maintenance of body tissues. While proteins play a role in various physiological functions, their primary function is not to assist in the absorption of vitamins (Choice B), help with the transport of nutrients in the blood (Choice C), or maintain fluid balance (Choice D).
3. What term describes foods that contain non-nutrient substances whose known action in the body is to promote well-being to a greater extent than that contributed by the food's nutrients?
- A. fortified foods
- B. enriched foods
- C. functional foods
- D. health-enhancing foods
Correct answer: C
Rationale: Functional foods are specifically designed to promote health benefits beyond basic nutrition. Fortified foods (choice A) are those with added nutrients that are not originally present, enriched foods (choice B) have nutrients added back that were lost during processing, and health-enhancing foods (choice D) is a vague and less specific term compared to functional foods.
4. In what position does the Pavlik harness hold a child's femurs for developmental hip dysplasia?
- A. Abduction
- B. Adduction
- C. Flexion
- D. Extension
Correct answer: A
Rationale: The Pavlik harness is designed to position a child's femurs in abduction for developmental hip dysplasia. Abduction helps align the hip joint correctly and promotes proper development in cases of hip dysplasia. Adduction (choice B) brings the legs closer to the midline, which is not the desired position in this condition. Flexion (choice C) refers to bending at a joint, while extension (choice D) is the opposite of flexion. However, in the case of developmental hip dysplasia, abduction is crucial for the Pavlik harness to work effectively.
5. What role do fats play in the human body?
- A. They provide a concentrated source of energy.
- B. They are the building blocks of enzymes and hormones.
- C. They are essential for brain function and development.
- D. They aid in the digestion of food.
Correct answer: D
Rationale: Fats play various essential roles in the human body, one of which is aiding in the digestion of food. While fats do provide a concentrated source of energy, the primary source is carbohydrates. Proteins are the building blocks of enzymes and hormones, not fats. Essential fatty acids found in fats are vital for brain function and development, but this is not the primary role of fats in the body.
