How should the nurse manage a child with acute lymphoblastic leukemia (ALL) who is receiving chemotherapy?

  • A. Avoid all physical activity
  • B. Ensure strict infection control measures
  • C. Increase daily caloric intake
  • D. Limit fluid intake
Correct Answer: B

Rationale: The correct answer is B: Ensure strict infection control measures. Children with acute lymphoblastic leukemia (ALL) who are undergoing chemotherapy have compromised immune systems, making them highly susceptible to infections. Implementing strict infection control measures, such as hand hygiene, limiting exposure to sick individuals, and maintaining a clean environment, is essential to prevent infections. Choice A is incorrect because avoiding all physical activity may not be necessary as long as the child's activity level is appropriate. Choice C is incorrect because increasing daily caloric intake is important to support the child's nutritional needs during treatment. Choice D is incorrect because limiting fluid intake is not typically recommended unless specifically advised by the healthcare provider.

Which nutrient source yields more than 4 kcalories per gram?

  • A. plant fats
  • B. plant proteins
  • C. animal proteins
  • D. plant carbohydrates
Correct Answer: A

Rationale: The correct answer is plant fats (Choice A). Fats, including plant fats, provide 9 kcalories per gram, which is more than 4 kcalories. Plant proteins (Choice B) and animal proteins (Choice C) provide 4 kcalories per gram. Plant carbohydrates (Choice D) also provide 4 kcalories per gram. Therefore, Choices B, C, and D are incorrect because they do not yield more than 4 kcalories per gram.

Which of the following is considered a micronutrient?

  • A. Protein
  • B. Carbohydrate
  • C. Vitamin C
  • D. Fat
Correct Answer: C

Rationale: Corrected Question: Vitamin C is considered a micronutrient because it is required in small amounts for proper body functioning and is essential for health. Proteins, carbohydrates, and fats are macronutrients, needed in larger quantities for energy and other body functions. Vitamin C, being a micronutrient, plays a crucial role in various bodily functions even though it is needed in smaller quantities compared to macronutrients. Therefore, the correct answer is C. Choice A (Protein), Choice B (Carbohydrate), and Choice D (Fat) are incorrect as they are macronutrients required in larger amounts for energy and other body functions.

What is a key dietary consideration for a child with phenylketonuria (PKU)?

  • A. High-fiber diet
  • B. Low-phenylalanine diet
  • C. Increased dairy intake
  • D. High-sodium diet
Correct Answer: B

Rationale: A low-phenylalanine diet is crucial for managing PKU to prevent neurological damage and maintain normal development. Phenylalanine is an amino acid found in protein-containing foods, and individuals with PKU have difficulty metabolizing it. Consuming foods low in phenylalanine helps prevent the buildup of toxic byproducts in the body. Choices A, C, and D are incorrect. A high-fiber diet, increased dairy intake, and high-sodium diet are not specific dietary considerations for PKU management. In fact, dairy products are a source of protein and phenylalanine, which should be limited in PKU.

What should be monitored in a child receiving chemotherapy?

  • A. Blood glucose levels
  • B. Blood cell counts
  • C. Weight gain
  • D. Skin elasticity
Correct Answer: B

Rationale: The correct answer is monitoring blood cell counts. During chemotherapy, it is crucial to monitor blood cell counts to detect potential side effects such as neutropenia (low white blood cell count) and anemia (low red blood cell count). These conditions can increase the risk of infections and fatigue. Monitoring blood glucose levels (Choice A) is not typically a primary concern in children receiving chemotherapy unless they have pre-existing conditions like diabetes. Weight gain (Choice C) and skin elasticity (Choice D) are not directly related to monitoring the effects of chemotherapy in children. Therefore, the most important parameter to monitor in a child receiving chemotherapy is blood cell counts.

How should a caregiver manage a child with a new diagnosis of sickle cell anemia?

  • A. Ensure the child receives frequent blood transfusions
  • B. Promote adequate hydration and pain management
  • C. Restrict physical activity
  • D. Administer high doses of vitamin C
Correct Answer: B

Rationale: Promoting adequate hydration and pain management is crucial for managing sickle cell anemia to prevent crises and complications. Adequate hydration helps prevent sickling of red blood cells, while effective pain management is essential for addressing the frequent pain episodes associated with the condition. Ensuring the child receives frequent blood transfusions is not the initial management for sickle cell anemia; transfusions are usually reserved for specific complications. Restricting physical activity should be individualized based on the child's condition; some physical activity is beneficial for overall health. Administering high doses of vitamin C is not a standard treatment for sickle cell anemia and does not address the underlying pathology of the disease.
