1. 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.
2. What should be monitored in a child with congenital adrenal hyperplasia (CAH)?
- A. Blood glucose levels
- B. Electrolyte balance
- C. Urine output
- D. Hemoglobin levels
Correct answer: B
Rationale: In a child with congenital adrenal hyperplasia (CAH), monitoring electrolyte balance is crucial. CAH can lead to adrenal insufficiency, causing imbalances in electrolytes such as sodium and potassium. Monitoring electrolyte levels helps in preventing complications like dehydration, electrolyte disturbances, and adrenal crisis. While blood glucose levels may need monitoring in other conditions like diabetes, it is not the primary concern in CAH. Urine output is important in assessing kidney function but is not a direct monitoring parameter for CAH. Hemoglobin levels are more relevant in conditions such as anemia, not specifically in CAH.
3. What intervention is recommended for a child with severe dehydration?
- A. Oral rehydration therapy
- B. Intravenous fluid replacement
- C. High-protein diet
- D. Increased physical activity
Correct answer: B
Rationale: Intravenous fluid replacement is the recommended intervention for a child with severe dehydration because it allows for rapid restoration of fluid and electrolyte balance. In severe cases, oral rehydration therapy (Choice A) may not be tolerated due to the child's condition. A high-protein diet (Choice C) is not the primary intervention and does not address the immediate fluid and electrolyte imbalance. Increased physical activity (Choice D) is contraindicated in severe dehydration as it can exacerbate fluid loss, making intravenous fluid replacement the most suitable choice for prompt correction of the severe dehydration.
4. 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.
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.
