A weight reduction regimen calls for a daily intake of 1400 kilocalories, which includes 30 grams of fat. What percentage of the total energy is contributed by fat?
- A. 8.50%
- B. 15.00%
- C. 19.00%
- D. 25.50%
Correct Answer: C
Rationale: To calculate the percentage of total energy contributed by fat, first determine the energy from fat by multiplying the fat amount (30g) by the energy density of fat (9 kcal/g), which equals 270 kcal. Then, divide the energy from fat (270 kcal) by the total energy intake (1400 kcal) and multiply by 100 to find the percentage: (270 kcal / 1400 kcal) * 100 = 19.29% ≈ 19.00%. Therefore, fat contributes approximately 19% of the total energy in the diet. Choice A (8.50%) is too low, while choices B (15.00%) and D (25.50%) are incorrect calculations based on the given information.

What should be included in the medical management of a sickle cell crisis?
- A. Information for parents on home care
- B. Adequate hydration and pain management
- C. Pain management and iron supplements
- D. Adequate oxygenation and factor VIII
Correct Answer: B
Rationale: The correct answer is B: Adequate hydration and pain management. During a sickle cell crisis, it is essential to provide hydration to prevent vaso-occlusive events and manage pain effectively with analgesics. Adequate hydration helps maintain blood flow and prevent further sickling of red blood cells. Pain management is crucial to alleviate the severe pain associated with sickle cell crises. Options A, C, and D are incorrect. Providing information for parents on home care (Option A) may be important for ongoing management but is not specific to an acute crisis. Iron supplements (Option C) are not typically indicated during a sickle cell crisis. Adequate oxygenation and factor VIII (Option D) are not primary interventions for managing a sickle cell crisis; instead, oxygen therapy may be considered in severe cases, and factor VIII is not a standard treatment for sickle cell disease.
What is a common complication of uncontrolled type 1 diabetes in children?
- A. Hyperactivity
- B. Ketoacidosis
- C. Hypertension
- D. Hypoglycemia
Correct Answer: B
Rationale: Ketoacidosis is a prevalent complication of uncontrolled type 1 diabetes in children. It is a serious condition characterized by high levels of ketones in the blood, leading to acidosis. Prompt medical attention is necessary to manage this potentially life-threatening condition.
Choice A, hyperactivity, is not a typical complication of uncontrolled type 1 diabetes. Choice C, hypertension, is not a direct complication of type 1 diabetes in children. Choice D, hypoglycemia, is more commonly associated with low blood sugar levels, which can occur due to excessive insulin administration or inadequate food intake in diabetic individuals, rather than uncontrolled type 1 diabetes.
What is the result of the metabolism of energy nutrients?
- A. Energy is released.
- B. Body fat increases.
- C. Energy is destroyed.
- D. Body water decreases.
Correct Answer: A
Rationale: The correct answer is A. Energy is released during the metabolism of energy nutrients. This released energy is utilized by the body for various functions. Choice B is incorrect because the metabolism of energy nutrients does not directly result in an increase in body fat. Choice C is incorrect as energy is not destroyed but rather transformed and utilized by the body. Choice D is incorrect as the metabolism of energy nutrients does not lead to a decrease in body water.
What is a primary goal of managing diabetes mellitus in children?
- A. Promote weight maintenance
- B. Prevent episodes of hypoglycemia
- C. Ensure normal growth and development
- D. Optimize blood sugar control
Correct Answer: C
Rationale: The primary goal of managing diabetes mellitus in children is to ensure normal growth and development. This involves maintaining stable blood glucose levels to prevent complications. Option A is incorrect because promoting weight gain is not a primary goal in managing diabetes; rather, the aim is to maintain a healthy weight. Option B is not the primary goal; although it is important to prevent episodes of hypoglycemia, the main focus is on overall management. Option D is incorrect as optimizing blood sugar control is a means to achieve the primary goal, which is ensuring normal growth and development.
What is an essential aspect of managing a child with juvenile idiopathic arthritis (JIA)?
- A. Encouraging joint mobility and physical therapy
- B. Restricting all forms of exercise
- C. Increasing sugar intake
- D. Using only oral medications
Correct Answer: A
Rationale: Encouraging joint mobility and physical therapy is crucial in managing juvenile idiopathic arthritis (JIA). This approach helps maintain joint function, reduce stiffness, and improve the overall quality of life for children with JIA. Restricting all forms of exercise (Choice B) is not recommended, as appropriate physical activity is beneficial for joint health and overall well-being. Increasing sugar intake (Choice C) is not a recommended practice for managing JIA, as a healthy diet is important for overall well-being and can help reduce inflammation. Using only oral medications (Choice D) may not be sufficient for managing JIA, as a comprehensive treatment plan often includes a combination of medications, physical therapy, and other interventions to effectively manage the condition.
