1. What physiologic state(s) produces the clinical manifestations of nervous system stimulation and excitement, such as overexcitability, nervousness, and tetany?

• A. Metabolic acidosis
• B. Respiratory alkalosis
• C. Metabolic and respiratory acidosis
• D. Metabolic and respiratory alkalosis

Correct answer: D

Rationale: Both metabolic and respiratory alkalosis can cause overexcitability and nervous system stimulation due to a decrease in ionized calcium levels, which can cause symptoms such as tetany and paresthesias. Acidosis typically has the opposite effect, leading to depression of the nervous system.

2. At what age is the first dose of the hepatitis A vaccine recommended to be started?

• A. 1 year
• B. 1 month
• C. 12 years
• D. It is not recommended at any age

Correct answer: A

Rationale: The correct answer is A: 1 year. The hepatitis A vaccine is now recommended for all children starting at age 1 year (i.e., 12 to 23 months). This is due to the recognition of hepatitis A as a significant child health problem, especially in areas with high infection rates. The virus is primarily spread through fecal-oral transmission, person-to-person contact, ingestion of contaminated food or water, and rarely through blood transfusion. Administering the first dose at 1 year helps protect children from this infection. Choices B and C are incorrect as the vaccine is not recommended at 1 month or 12 years. Choice D is also incorrect as the hepatitis A vaccine is recommended at a specific age to prevent the infection.

3. Which statement regarding bottle mouth caries requires further teaching?

• A. Caries can be decreased by putting an infant to bed with a bottle of milk or sweetened juice
• B. Eliminating the bedtime bottle or substituting water is recommended
• C. Sugar pools within the oral cavity cause severe decay
• D. It is often seen in children between 18 months and 3 years

Correct answer: A

Rationale: The correct answer is A. Putting an infant to bed with a bottle of milk or sweetened juice increases the risk of bottle mouth caries rather than decreasing it. This statement requires further teaching as it provides incorrect information. Choice B is correct as eliminating the bedtime bottle or substituting water is recommended to prevent bottle mouth caries. Choice C is also correct as sugar pooling within the oral cavity can indeed cause severe decay. Choice D is correct as bottle mouth caries is often observed in children between 18 months and 3 years.

4. Following treatment for iron deficiency anemia, the physician orders lab tests. Which lab value would indicate an improvement in the child’s condition?

• A. Low hemoglobin
• B. Normal platelet count
• C. High reticulocyte count
• D. Low hematocrit

Correct answer: C

Rationale: A high reticulocyte count indicates that the bone marrow is producing more red blood cells, which is a sign of recovery from anemia as the body replenishes its iron stores and increases hemoglobin levels. Low hemoglobin (Choice A) would indicate ongoing anemia rather than improvement. A normal platelet count (Choice B) and low hematocrit (Choice D) are not specific indicators of improvement in iron deficiency anemia.

5. The nurse is caring for a child receiving chemotherapy with the following orders: Zantac 70 mg IV in normal saline 30 mL to infuse over 30 minutes. The nurse should set the infusion pump to deliver how many mL/hour?

• A. 60 mL/hour
• B. 45 mL/hour
• C. 30 mL/hour
• D. 15 mL/hour

Correct answer: A

Rationale: The correct answer is A: 60 mL/hour. The total volume to be infused is 30 mL over 30 minutes. To calculate the infusion rate in mL/hour, divide the total volume by the total time in hours. In this case, 30 mL / 0.5 hours = 60 mL/hour. Choice B, 45 mL/hour, is incorrect as it does not correspond to the calculated infusion rate. Choices C and D, 30 mL/hour and 15 mL/hour respectively, are also incorrect based on the calculation.
