Nursing Elites

1. A child who received multiple blood transfusions after correction of a congenital heart defect is demonstrating muscular irritability and oozing blood from the surgical incision. Which serum value is most important for the nurse to obtain before reporting to the healthcare provider?

• A. CO2 combining power
• B. Calcium
• C. Sodium
• D. Chloride

Correct answer: B

Rationale: The correct answer is Calcium. In this scenario, the child is displaying symptoms of muscular irritability and oozing blood, which are indicative of hypocalcemia. Calcium levels are crucial to monitor after multiple blood transfusions to prevent complications such as hypocalcemia, which can lead to these symptoms. Therefore, obtaining a serum calcium value is essential for the nurse to assess and address the child's condition effectively. CO2 combining power, Sodium, and Chloride levels are not directly associated with the symptoms described and are not the priority in this situation.

2. What maternal behavior is typically observed when a new mother first receives her infant?

• A. She eagerly reaches for the infant, undresses the infant, and examines the infant completely.
• B. Her arms and hands receive the infant and she then traces the infant's profile with her fingertips.
• C. Her arms and hands receive the infant and she then cuddles the infant to her own body.
• D. She eagerly reaches for the infant and then holds the infant close to her own body.

Correct answer: B

Rationale: When a new mother first receives her infant, a typical maternal behavior is to use her arms and hands to receive the infant and then trace the infant's profile with her fingertips. This action is a gentle way of bonding with the newborn and aids in recognizing the infant's features. Choices A, C, and D are incorrect as they do not accurately describe the common behavior of tracing the infant's profile, which is a significant part of the initial interaction between a mother and her newborn.

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. When can a woman who thinks she may be pregnant use a home pregnancy test to diagnose pregnancy?

• A. A home pregnancy test can be used right after your first missed period.
• B. These tests are most accurate after you have missed your second period.
• C. Home pregnancy tests often give false positives and should not be trusted.
• D. The test can provide accurate information when used right after ovulation.

Correct answer: A

Rationale: The correct answer is A. Home pregnancy tests detect hCG, a hormone produced during pregnancy, and are most accurate after the first missed period when hCG levels are higher. Testing too early may result in a false negative. Waiting until after the first missed period increases the reliability of the test results. Choice B is incorrect as waiting until after the second missed period is unnecessary and may delay seeking appropriate healthcare. Choice C is incorrect as home pregnancy tests are generally reliable when used correctly. Choice D is incorrect because ovulation occurs before the period, and testing immediately after ovulation may not provide accurate results.

5. A 34-week primigravida woman with preeclampsia is receiving Lactated Ringer’s 500ml with magnesium sulfate 20 grams at the rate of 3g/hr. How many ml/hr should the nurse program the infusion pump?

• A. 75ml/hr
• B. 100ml/hr
• C. 50ml/hr
• D. 25ml/hr

Correct answer: A

Rationale: To calculate the infusion rate, divide the total quantity to be infused (500ml) by the total time (1 hour) which equals 500ml/hr. Since the magnesium sulfate is being given at 3g/hr, and 1g of magnesium sulfate is in 5ml of solution, the rate will be 3g/hr x 5ml/g = 15ml/hr. Therefore, the total infusion rate should be 500ml/hr + 15ml/hr = 515ml/hr. Hence, the nurse should program the infusion pump to deliver 75ml/hr (515ml/hr total - 500ml/hr Lactated Ringer's rate). This choice is correct because it accounts for both the Lactated Ringer's and magnesium sulfate rates. Choice B, 100ml/hr, is incorrect as it does not consider the additional magnesium sulfate infusion rate. Choice C, 50ml/hr, is incorrect because it does not account for the magnesium sulfate infusion. Choice D, 25ml/hr, is incorrect as it is too low and does not consider the magnesium sulfate being infused concurrently.
