Question 1 of 5
The nurse is teaching parents of a newborn about feeding their infant. Which of the following instructions should the nurse include?
Correct Answer: A
Rationale: The correct answer is to use the defrost setting on microwave ovens to warm bottles. It is essential for parents to be cautious when warming bottles in a microwave oven to prevent superheating of the milk. Choosing the defrost setting and checking the formula temperature before giving it to the baby helps avoid burns. Discarding partially used bottles after 24 hours when refrigerating formula is crucial as it reduces the risk of harmful bacterial growth. Mixing formula concentrate with water in a 1:1 ratio of one part concentrate to one part water ensures proper dilution of the formula. On the other hand, powdered formula should be mixed following the package instructions, typically using two parts water to one part powder. This accurate mixing ratio provides the necessary balance of nutrients for the baby. Adding fresh formula to partially used bottles can introduce pathogens that may harm the infant, underscoring the importance of discarding partially used bottles and preparing formula correctly.
Therefore, options B, C, and D are incorrect as they do not address the safe and proper ways to feed a newborn effectively.
Question 2 of 5
What is the therapeutic range for carbamazepine (Tegretol)?
Correct Answer: B
Rationale: The therapeutic range for carbamazepine (Tegretol) is 4-10 mcg/mL. This range is established based on the optimal balance between effectiveness and safety.
Choices A, C, and D are outside the therapeutic range for carbamazepine, which could lead to suboptimal treatment outcomes or increased risk of toxicity.
Choice B (4-10 mcg/mL) is the correct range recommended for therapeutic efficacy while minimizing adverse effects.
Question 3 of 5
The nurse is assessing the dental status of an 18-month-old child. How many teeth should the nurse expect to examine?
Correct Answer: C
Rationale: An 18-month-old child should have approximately 12 teeth. Children typically start getting teeth around 6 months of age. By subtracting 6 from the number of months in the child's age, you can calculate the expected number of teeth. For an 18-month-old child, 18 - 6 = 12 teeth.
Therefore, the correct answer is 12 teeth.
Choices A, B, and D are incorrect because they do not align with the expected dental development in an 18-month-old child.
Question 4 of 5

Therefore, options B, C, and D are incorrect as they do not address the safe and proper ways to feed a newborn effectively.
Question 5 of 5
An assessment of the skull of a normal 10-month-old baby should identify which of the following?
Correct Answer: A
Rationale: The correct answer is the closure of the posterior fontanel. By 10 months of age, the posterior fontanel should be closed. The anterior fontanel typically closes around 12-18 months of age. Overlapping of cranial bones is not a normal finding and may indicate craniosynostosis, a condition where the sutures close too early. Ossification of the sutures is also not a normal finding in a 10-month-old baby as the sutures should remain open to allow for the growth of the skull.
