1. 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.

2. What is the priority assessment for a child with suspected appendicitis?

• A. Temperature
• B. Heart rate
• C. Respiratory rate
• D. Pain level

Correct answer: D

Rationale: The priority assessment for a child with suspected appendicitis is 'Pain level.' Evaluating the pain level, particularly in the lower right quadrant, is crucial as it helps in determining the severity of the condition, leading to prompt diagnosis and treatment. Monitoring temperature, heart rate, and respiratory rate are important aspects of assessment; however, they are secondary to assessing the pain level in cases of suspected appendicitis. Pain assessment is key in diagnosing this condition since the classic presentation includes abdominal pain that often starts around the umbilicus and then localizes to the right lower quadrant.

3. Parents of a 6-month-old child, diagnosed with iron deficiency anemia, ask why it was not diagnosed earlier. What should the nurse say?

• A. Are you sure your child has iron deficiency anemia?
• B. Maternal stores of iron are depleted at about 6 months.
• C. This anemia is caused by blood loss.
• D. The child may not have had it for a long time.

Correct answer: B

Rationale: The correct answer is B: 'Maternal stores of iron are depleted at about 6 months.' Iron deficiency anemia becomes apparent around 6 months of age when the infant's iron stores, primarily received from the mother during pregnancy, are depleted. This timing coincides with the introduction of solid foods, which may lack sufficient iron. Choices A, C, and D are incorrect because they do not address the specific reason why iron deficiency anemia is typically diagnosed around 6 months of age.

4. 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.

5. How is gastroesophageal reflux (GER) typically treated in infants?

• A. Keeping the infant NPO
• B. Thickening the formula or breast milk with cereal
• C. Placing the infant to sleep on the side
• D. Switching the infant to cow's milk

Correct answer: B

Rationale: Thickening the formula or breast milk with cereal is a common treatment for gastroesophageal reflux (GER) in infants. By adding cereal, the feedings become heavier, making it less likely for the stomach contents to reflux. Keeping the infant NPO (nothing by mouth) is not typically necessary for GER treatment and might not be appropriate. Placing the infant to sleep on the side is not recommended due to the risk of sudden infant death syndrome (SIDS). Switching the infant to cow's milk is also not a recommended treatment for GER as it can exacerbate symptoms due to its protein content.
