1. A loading dose of terbutaline (Brethine) 250 mcg IV is prescribed for a client in preterm labor. Brethine 20 mg is added to 1,000 mL of D5W. How many milliliters of the solution should the nurse administer?
- A. 45
- B. 15 mL
- C. 4
- D. 13
Correct answer: D
Rationale: To calculate the amount of terbutaline to administer, first convert the dose to the same unit. 250 mcg = 0.25 mg. Next, set up a proportion: 20 mg is to 1000 mL as 0.25 mg is to X mL. Cross multiply and solve for X: 20 × X = 0.25 × 1000. X = (0.25 × 1000) / 20 = 12.5 mL. Therefore, the nurse should administer 13 mL of the solution. Choice A is incorrect as it does not reflect the correct calculation. Choice B is incorrect as it does not consider the accurate conversion and calculation. Choice C is incorrect as it is not the result of the correct proportion calculation.
2. A client receiving oxytocin (Pitocin) to augment early labor. Which assessment is most important for the nurse to obtain each time the infusion rate is increased?
- A. Pain level
- B. Blood pressure
- C. Infusion site
- D. Contraction pattern
Correct answer: D
Rationale: When a client is receiving oxytocin to augment labor, the most crucial assessment for the nurse to obtain each time the infusion rate is increased is monitoring the contraction pattern. Increasing the infusion rate of oxytocin can lead to stronger and more frequent contractions, which can have implications for both the mother and the baby. Monitoring the contraction pattern helps ensure the safe administration of oxytocin and allows for timely interventions if needed.
3. What action should the nurse take if an infant, who was born yesterday weighing 7.5 lbs (3,402 grams), weighs 7 lbs (3,175 grams) today?
- A. Inform and assure the mother that this is normal weight loss.
- B. Encourage the mother to increase the frequency of breastfeeding.
- C. After verifying the accuracy of weight, notify the healthcare provider.
- D. Monitor the stool and urine output of the neonate for the last 24 hours.
Correct answer: A
Rationale: The correct action for the nurse to take in this situation is to inform and assure the mother that this weight loss is normal. Newborns can lose up to 10% of their birth weight in the first few days after birth, which is attributed to fluid loss and adjustment to life outside the womb. This weight loss is typically regained within the first two weeks of life. It is crucial for the nurse to educate and provide reassurance to the mother about this common occurrence in newborns.
4. During a prenatal visit, the nurse discusses with a client the effects of smoking on the fetus. When compared with nonsmokers, mothers who smoke during pregnancy tend to produce infants who have
- A. lower Apgar scores.
- B. lower birth weights.
- C. respiratory distress.
- D. a higher rate of congenital anomalies.
Correct answer: B
Rationale: Smoking during pregnancy is associated with intrauterine growth restriction, leading to lower birth weights. This occurs due to the harmful effects of smoking on fetal development, which can result in reduced nutrient and oxygen supply to the fetus, impacting its overall growth and leading to lower birth weights. Choices A, C, and D are incorrect as smoking during pregnancy primarily affects fetal growth and development, leading to lower birth weights rather than lower Apgar scores, respiratory distress, or a higher rate of congenital anomalies.
5. 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.
