1. How much energy is required to raise the temperature of one kilogram of water by 1°C?

• A. 10 calories
• B. 100 calories
• C. 1 kilocalorie
• D. 10 kilocalories

Correct answer: C

Rationale: The correct answer is 1 kilocalorie. This is the amount of energy required to raise the temperature of 1 kilogram of water by 1°C. Choice A (10 calories) and Choice D (10 kilocalories) are incorrect as they do not represent the correct unit of measurement for this specific scenario. Choice B (100 calories) is also incorrect as it overestimates the amount of energy required. The specific heat capacity of water is approximately 1 calorie/gram °C, which means that 1 kilogram (1000 grams) of water requires 1 kilocalorie (1000 calories) to raise its temperature by 1°C.

2. The parents of a child with sickle cell anemia ask why their child experiences pain. What is the most likely cause?

• A. Inflammation of the vessels
• B. Obstructed blood flow
• C. Overhydration
• D. Stress-related headaches

Correct answer: B

Rationale: In sickle cell anemia, pain is primarily caused by the obstruction of blood flow by sickle-shaped cells. This obstruction leads to inadequate oxygen supply to tissues, resulting in tissue damage and pain. Choice A, inflammation of the vessels, is incorrect as it is not the primary cause of pain in sickle cell anemia. Choice C, overhydration, is unrelated to the pathophysiology of sickle cell anemia and would not lead to the characteristic pain experienced. Choice D, stress-related headaches, is also unrelated to the underlying mechanisms of pain in sickle cell anemia.

3. What is the recommended treatment for a child with a first-degree burn?

• A. Immediate application of ice
• B. Administration of oral antibiotics
• C. Application of cool, moist compresses
• D. Application of hot packs

Correct answer: C

Rationale: The recommended treatment for a child with a first-degree burn is the application of cool, moist compresses. This helps in reducing pain and swelling without causing further damage to the skin. Applying ice directly to a burn can lead to frostbite and worsen the injury (Choice A). Oral antibiotics are not necessary for first-degree burns as they do not typically involve infection (Choice B). Hot packs should be avoided as they can further damage the skin and increase inflammation (Choice D).

4. Following diarrhea, which foods should be offered to the school-age child?

• A. Apricots and peaches
• B. Chocolate milk
• C. Applesauce and milk
• D. Bananas and rice

Correct answer: D

Rationale: After a bout of diarrhea, it is important to offer foods that are gentle on the stomach and help in recovery. Bananas and rice are commonly recommended as they are easily digestible and can help firm up stools. Apricots, peaches, and applesauce may be too acidic and fibrous, potentially aggravating the stomach. Chocolate milk is high in sugar and can worsen diarrhea due to its lactose content.

5. How should a healthcare professional manage a child with a newly inserted central venous catheter?

• A. Monitor for signs of infection
• B. Restrict all physical activity
• C. Administer routine antibiotics
• D. Increase fluid intake only

Correct answer: A

Rationale: Monitoring for signs of infection is crucial in managing a central venous catheter to prevent complications. This involves observing for redness, swelling, warmth, or drainage at the catheter site, as these can indicate an infection. Restricting physical activity unnecessarily (choice B) can hinder the child's recovery and quality of life. Administering routine antibiotics (choice C) without a confirmed infection can lead to antibiotic resistance and unnecessary side effects. Increasing fluid intake only (choice D) is not the primary intervention for managing a central venous catheter.
