1. Upon arrival in the nursery, a newborn infant is breathing satisfactorily but appears dusky. What action should the LPN/LVN take first?

A. Notify the healthcare provider immediately.
B. Suction the infant's nares, then the oral cavity.
C. Check the infant's oxygen saturation rate.
D. Position the infant on the right side.

Correct answer: C

Rationale: The priority action in this scenario is to check the infant's oxygen saturation rate. This will provide crucial information on the infant's oxygen levels and the need for immediate oxygen therapy. Assessing oxygen saturation is essential in determining the severity of hypoxia and guiding further interventions to ensure adequate oxygenation. Option A is not the priority as immediate intervention related to oxygenation is needed before notifying the healthcare provider. Suctioning (Option B) may be necessary but should come after assessing oxygen saturation. Positioning the infant (Option D) does not address the immediate need to evaluate oxygen levels.

2. A 4-year-old boy presents with a rash and is diagnosed with varicella (chickenpox). What is the most appropriate intervention to manage this condition?

A. Administer oral acyclovir.
B. Apply calamine lotion to soothe itching.
C. Encourage scratching to relieve itching.
D. Encourage bed rest to avoid spreading the rash.

Correct answer: B

Rationale: The most appropriate intervention for managing varicella (chickenpox) in a 4-year-old child is to apply calamine lotion to soothe itching. Calamine lotion helps alleviate the itching associated with the chickenpox rash, providing relief to the child. It is important to discourage scratching to prevent complications such as scarring or secondary bacterial infections. Encouraging bed rest can be beneficial for comfort but is not the primary intervention to manage chickenpox.

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. The healthcare provider is reviewing the serum laboratory findings for a 5-day-old infant with congenital adrenal hyperplasia. Which laboratory result should be reported to the healthcare provider immediately?

A. Bilirubin of 1.5 mg/dl.
B. Glucose of 80 mg/dl.
C. Potassium of 4.5 mEq/L.
D. Sodium of 119 mEq/L.

Correct answer: D

Rationale: Low sodium levels in congenital adrenal hyperplasia can indicate salt-wasting crisis, which is a life-threatening emergency requiring immediate medical attention. Monitoring sodium levels is crucial to prevent complications such as dehydration and shock in these patients.

5. The healthcare provider prescribes Amoxicillin 500mg PO every 8hrs for a child who weighs 22 pounds. The available suspension is labeled Amoxicillin Suspension 250mg/5ml. The recommended maximum dose is 50mg/kg/24hr. How many mL should the nurse administer in a single dose based on the child’s weight?

A. 10mL
B. 15mL
C. 7.5mL
D. 5mL

Correct answer: A

Rationale: To calculate the dose for the child weighing 22 pounds, first convert the weight to kg: 22 lbs ÷ 2.2 = 10 kg. The maximum dose based on weight would be 10 kg × 50 mg/kg/24hr = 500 mg/24hr. Since the medication is prescribed every 8 hours, the dose for each administration would be 500 mg ÷ 3 doses = 166.67 mg. As the available suspension is 250mg/5ml, the nurse should administer 166.67 mg ÷ 250 mg/mL = 0.67 mL per dose. However, since it's not practical to administer a fraction of a milliliter, the nurse should round up to the nearest appropriate dose, which is 10mL.
