1. What is the MOST common cause of shock in infants and children?

• A. Severe allergic reaction
• B. Dehydration
• C. Accidental poisoning
• D. Cardiac failure

Correct answer: B

Rationale: Dehydration is the most common cause of shock in infants and children. In children, the body's fluid reserves are smaller compared to adults, making them more susceptible to dehydration, which can lead to shock if not promptly addressed. Severe allergic reactions, accidental poisoning, and cardiac failure can also cause shock, but dehydration is the most frequent cause in this age group.

2. In educating the parents of a child diagnosed with hypothyroidism, the nurse mentions that the child should avoid goitrogens. Which of the following will the nurse mention as an example?

• A. Orange
• B. Tomatoes
• C. Cabbage
• D. Grapes

Correct answer: C

Rationale: Cabbage is an example of a goitrogen that should be avoided in children with hypothyroidism. Goitrogens are substances that can interfere with thyroid function by inhibiting iodine uptake, potentially worsening the condition. Cabbage, along with other cruciferous vegetables like broccoli and cauliflower, contains compounds that can affect thyroid hormone production. Oranges, tomatoes, and grapes are not classified as goitrogens. Therefore, it is important for parents to be aware of foods like cabbage and to limit their child's intake to help manage their hypothyroidism effectively.

3. In public education on Typhoid fever, the condition mainly spreads through:

• A. Contaminated air
• B. Mineral water
• C. Contaminated food and water
• D. All of the above

Correct answer: C

Rationale: Typhoid fever is primarily spread through contaminated food and water, usually due to poor sanitation practices. The bacteria responsible for typhoid fever, Salmonella Typhi, is typically found in food or water contaminated by the feces of an infected person. Contaminated air is not a significant mode of transmission for typhoid fever, making choice A incorrect. While waterborne transmission can occur, it is through contaminated water rather than specifically mineral water, making choice B incorrect. Therefore, the correct answer is C, as contaminated food and water are the main sources of transmission for typhoid fever.

4. When a father asks why his child with tetralogy of Fallot seems to favor a squatting position, the nurse would explain that squatting:

• A. Increases peripheral vascular resistance
• B. Decreases arterial blood flow away from the heart
• C. It's a common resting position when a child is tachycardic
• D. Increases the workload of the heart

Correct answer: A

Rationale: Squatting increases systemic vascular resistance, which leads to a reduction in the right-to-left shunting of blood in children with tetralogy of Fallot. This helps improve oxygenation by balancing the pulmonary and systemic blood flow. The squatting position decreases the pressure in the right ventricle and reduces the magnitude of the right-to-left shunt by increasing afterload, thereby improving oxygenation. Choices B, C, and D are incorrect because squatting does not decrease arterial blood flow away from the heart, is not related to being tachycardic, and does not increase the workload of the heart.

5. Justine is admitted to the pediatric unit due to the occurrence of diabetic ketoacidosis signaling a new diagnosis of diabetes. The diabetes team explores the cause of the episode and takes steps to prevent a recurrence. Diabetic ketoacidosis (DKA) results from an excessive accumulation of which of the following?

• A. Sodium bicarbonate from renal compensation
• B. Potassium from cell death
• C. Glucose from carbohydrate metabolism
• D. Ketone bodies from fat metabolism

Correct answer: D

Rationale: Diabetic ketoacidosis (DKA) results from the excessive accumulation of ketone bodies from fat metabolism. During DKA, there is a lack of insulin leading to the breakdown of fat stores into fatty acids and their subsequent conversion into ketone bodies. These ketone bodies accumulate in the blood, leading to metabolic acidosis and the characteristic symptoms of DKA.
