The nurse is caring for a child with sickle cell anemia with the following order: Morphine Sulfate 2 mg IV every 24 hours. Morphine Sulfate is available in 10 mg/1mL. How many mL should the nurse administer?
- A. 0.2 mL
- B. 0.5 mL
- C. 1 mL
- D. 2 mL
Correct Answer: A
Rationale: To administer 2 mg of Morphine Sulfate when the concentration is 10 mg/mL, the nurse should administer 0.2 mL (2 mg / 10 mg/mL = 0.2 mL). Choice B, 0.5 mL, is incorrect because it is the result of dividing 2 mg by 4 mg/mL instead of 10 mg/mL. Choice C, 1 mL, is incorrect as it would be the result of dividing 2 mg by 2 mg/mL. Choice D, 2 mL, is incorrect as it would be the result of dividing 2 mg by 1 mg/mL.

In the newborn, into what muscle is intramuscular vitamin K administered?
- A. Deltoid
- B. Dorsogluteal
- C. Rectus femoris
- D. Vastus lateralis
Correct Answer: D
Rationale: In newborns, intramuscular vitamin K is traditionally administered into the vastus lateralis muscle. This site is preferred due to its large muscle mass and accessibility. The dorsogluteal site is not recommended for newborns due to the risk of injury to the sciatic nerve. The deltoid site is also not recommended for newborns. The rectus femoris muscle is not commonly used for intramuscular injections in newborns.
The clinic nurse is teaching parents about physiologic anemia that occurs in infants. What statement should the nurse include about the cause of physiologic anemia?
- A. Maternally derived iron stores are depleted in the first 2 months.
- B. Fetal hemoglobin results in a shortened survival of red blood cells.
- C. The production of adult hemoglobin decreases in the first year of life.
- D. Low levels of fetal hemoglobin depress the production of erythropoietin.

What approach is the most appropriate when performing a physical assessment on a toddler?
- A. Demonstrate the use of equipment
- B. Perform traumatic procedures last
- C. Use minimum physical contact initially
- D. Always proceed systematically in a head-to-toe direction
Correct Answer: C
Rationale: The most appropriate approach when performing a physical assessment on a toddler is to use minimum physical contact initially. This helps gain the toddler's cooperation and reduces their distress. Performing traumatic procedures last is crucial as they are likely to upset the child and should be handled with care. Demonstrating the use of equipment may be complex for toddlers to understand, so it is not the most appropriate initial approach. Proceeding systematically in a head-to-toe direction is a good practice but using minimum physical contact initially is more important to establish trust and cooperation with the toddler.
The clinic nurse is assessing a child with a heavy ascariasis lumbricoides (common roundworm) infection. Which assessment findings should the nurse expect?
- A. Anemia
- B. Anorexia
- C. All are applicable
- D. Intestinal colic
Correct Answer: D
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
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.
