Nursing Elites

1. 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.

2. A young woman who underwent a liver transplant one year ago tells the clinic nurse that she would like to start a family. How should the nurse intervene?

• A. Provide information about the high-risk nature of her pregnancy.
• B. Gently remind the client that anti-rejection drugs can cause sterility.
• C. Explain the benefits of waiting for a five-year post-transplant period.
• D. Determine if the client is considering options for adopting a child.

Correct answer: A

Rationale: Post-liver transplant pregnancy is high-risk due to potential complications associated with immunosuppressive therapy and the transplanted organ's health. Providing information about the risks involved allows the client to make an informed decision regarding family planning.

3. After a full-term vaginal delivery, a postpartum client's white blood cell count is 15,000/mm3. What action should the nurse take first?

• A. Check the differential, as the WBC count can be normal for this client.
• B. Assess the client's temperature, pulse, and respirations every 4 hours.
• C. Notify the healthcare provider, as this finding may indicate infection.
• D. Assess the client's perineal area for signs of a perineal hematoma.

Correct answer: A

Rationale: In postpartum clients, a white blood cell count of 15,000/mm3 can be within normal limits due to physiological changes that occur after childbirth. Checking the differential count would provide a more detailed analysis of the specific types of white blood cells present, helping to differentiate between normal postpartum changes and potential infection. This action allows the nurse to gather more information before escalating the situation to the healthcare provider or initiating other assessments. Assessing vital signs and the perineal area are important aspects of postpartum care but may not be the priority in this scenario where the white blood cell count can be influenced by normal physiological changes.

4. 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.

5. A breastfeeding infant, screened for congenital hypothyroidism, is found to have low levels of thyroxine (T4) and high levels of thyroid-stimulating hormone (TSH). What is the best explanation for this finding?

• A. The thyroxine level is low because the TSH level is high.
• B. High thyroxine levels do not normally occur in breastfeeding infants.
• C. The thyroid gland does not produce normal levels of thyroxine for several weeks after birth.
• D. The TSH is high because of the low production of T4 by the thyroid.

Correct answer: D

Rationale: High TSH and low T4 levels indicate that the thyroid gland is not producing enough hormones, which is a sign of congenital hypothyroidism. In this case, the high TSH is a compensatory response by the body to stimulate the thyroid to produce more T4. Choice A is incorrect because TSH does not directly affect T4 levels; rather, it is the other way around where low T4 levels lead to high TSH levels. Choice B is incorrect because high thyroxine levels are not expected in congenital hypothyroidism. Choice C is incorrect as the thyroid gland should be producing normal levels of thyroxine shortly after birth, making this explanation unlikely in the context of congenital hypothyroidism.
