1. The nurse is measuring the frontal occipital circumference (FOC) of a 3-month-old infant, notes that the FOC has increased by 5 cm since birth, and observes that the child’s head appears large in relation to body size. Which action is most important for the nurse to take next?

A. Measure the infant’s head-to-heel length
B. Observe the infant for sunsetting eyes
C. Palpate the anterior fontanel for tension and bulging
D. Plot the measurement on the infant’s growth chart

Correct answer: C

Rationale: Palpating the anterior fontanel for tension and bulging is essential to assess for increased intracranial pressure, which could be indicated by the enlarged head circumference. This assessment can help identify potential neurological issues that need prompt attention.

2. Insulin therapy is initiated for a 12-year-old child who is admitted with diabetic ketoacidosis (DKA). Which action is most important for the nurse to include in the child’s plan of care?

A. Monitor serum glucose for adjustment in the infusion rate of regular insulin (Novolin R).
B. Determine the child’s compliance schedule for subcutaneous NPH insulin (Humulin N).
C. Demonstrate to the parents how to program an insulin pen for daily glucose regulation.
D. Consult with the healthcare provider about the use of insulin detemir (Levemir Flex Pen).

Correct answer: A

Rationale: In managing diabetic ketoacidosis (DKA), monitoring serum glucose levels is crucial to adjust the infusion rate of regular insulin effectively. This helps in controlling blood glucose levels and preventing complications associated with DKA. Close monitoring and adjustments based on glucose levels are essential for the successful management of DKA. Choice B is incorrect as it focuses on a different type of insulin and compliance schedule without addressing the immediate needs of managing DKA. Choice C is not the priority action and involves educating parents on a different method of insulin administration. Choice D is also not the most important action as it suggests consulting with the healthcare provider about a different type of insulin rather than focusing on immediate glucose monitoring for insulin adjustment in DKA management.

3. After each feeding, a 3-day-old newborn is spitting up large amounts of Enfamil® Newborn Formula, a nonfat cow's milk formula. The pediatric healthcare provider changes the neonate's formula to Similac® Soy Isomil® Formula, a soy protein isolate-based infant formula. What information should the LPN/LVN provide to the mother about the newly prescribed formula?

A. The new formula is a coconut milk formula used with babies with impaired fat absorption.
B. Enfamil® Formula is a demineralized whey formula that is needed with diarrhea.
C. The new formula is a casein protein source that is low in phenylalanine.
D. Similac® Soy Isomil® Formula is a soy-based formula that contains sucrose.

Correct answer: D

Rationale: The LPN/LVN should inform the mother that Similac® Soy Isomil® Formula is a soy-based formula containing sucrose. This formula is suitable for infants with cow's milk protein allergy or intolerance, which may be the reason for the newborn spitting up large amounts of the previous cow's milk formula.

4. Assessment findings of a 4-hour-old newborn include: axillary temperature of 96.8°F (35.8°C), heart rate of 150 beats/minute with a soft murmur, irregular respiratory rate at 64 breaths/minute, jitteriness, hypotonia, and weak cry. Based on these findings, which action should the nurse implement?

A. Swaddle the infant in a warm blanket.
B. Obtain a heel stick blood glucose level.
C. Place a pulse oximeter on the heel.
D. Document the findings in the record.

Correct answer: B

Rationale: The assessment findings in the newborn, such as jitteriness, weak cry, and hypotonia, are indicative of potential hypoglycemia. To confirm this suspicion, the nurse should obtain a heel stick blood glucose level, which is the most appropriate action in this situation. Checking the blood glucose level will provide crucial information to determine the newborn's glucose status and guide further management if hypoglycemia is confirmed. Swaddling the infant in a warm blanket does not address the underlying issue of potential hypoglycemia and may not effectively raise the blood glucose level. Placing a pulse oximeter on the heel is not indicated for assessing hypoglycemia. Documenting the findings in the record is important but does not address the immediate concern of assessing and managing potential hypoglycemia.

5. A 4-week-old premature infant has been receiving epoetin alfa (Epogen) for the last three weeks. Which assessment finding indicates to the healthcare provider that the drug is effective?

A. Slowly increasing urinary output over the last week.
B. Respiratory rate changes from the 40s to the 60s.
C. Changes in apical heart rate from the 180s to the 140s.
D. Change in indirect bilirubin from 12 mg/dl to 8 mg/dl.

Correct answer: C

Rationale: The correct answer is C. Epoetin alfa stimulates erythropoiesis, leading to an increase in red blood cell production and improving oxygen-carrying capacity. As the oxygenation status improves, there is a reduction in heart rate. Therefore, changes in apical heart rate from the 180s to the 140s indicate that the drug is effective. Choices A, B, and D are incorrect because they do not directly reflect the expected outcome of epoetin alfa therapy. Increasing urinary output, changes in respiratory rate, and decreasing bilirubin levels are not primary indicators of the drug's effectiveness in this context.
