Nursing Elites

1. A nurse is admitting a term newborn following a cesarean birth. The nurse observes that the newborn's skin is slightly yellow. This finding indicates the newborn is experiencing a complication related to which of the following?

• A. Maternal/newborn blood group incompatibility
• B. Absence of vitamin K
• C. Physiologic jaundice
• D. Maternal cocaine abuse

Correct answer: A

Rationale: The yellow skin observed in the newborn suggests jaundice. Maternal/newborn blood group incompatibility is a common cause of jaundice in newborns. This occurs when the mother and baby have different blood types, leading to the baby's immune system attacking the red blood cells, causing jaundice. Physiologic jaundice, which is a normal process due to the breakdown of red blood cells in newborns, typically presents after the first 24 hours of life. Absence of vitamin K leads to bleeding issues, not jaundice. Maternal cocaine abuse does not directly cause jaundice in newborns.

2. A healthcare professional is preparing to administer magnesium sulfate 2 g/hr IV to a client who is in preterm labor. Available is 20 g of magnesium sulfate in 500 mL of dextrose 5% in water (D5W). How many mL/hr should the IV infusion pump be set to administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

• A. 60
• B. 30
• C. 50
• D. 80

Correct answer: C

Rationale: To administer magnesium sulfate 2 g/hr IV, the healthcare professional should set the IV infusion pump to administer 50 mL/hr. The calculation is as follows: 20 g / 500 mL = 2 g / X mL, X = 50 mL/hr. Choice A (60 mL/hr) is incorrect as it does not match the calculated rate. Choice B (30 mL/hr) is incorrect as it is half of the calculated rate. Choice D (80 mL/hr) is incorrect as it is higher than the calculated rate.

3. When should a provider order a maternal serum alpha-fetoprotein (MSAFP) screening for pregnant clients?

• A. A client who has mitral valve prolapse
• B. A client who has been exposed to AIDS
• C. All pregnant clients
• D. A client who has a history of preterm labor

Correct answer: C

Rationale: Maternal serum alpha-fetoprotein (MSAFP) screening is recommended for all pregnant clients to assess the risk of neural tube defects. It is a routine screening test used to detect increased levels of alpha-fetoprotein in maternal blood, which may indicate a higher risk for conditions such as neural tube defects in the developing fetus. Therefore, all pregnant clients, regardless of their medical history or risk factors, should undergo MSAFP screening as part of routine prenatal care. Choices A, B, and D are incorrect because the MSAFP screening is not specific to certain medical conditions or histories; it is a standard screening procedure for all pregnant individuals to evaluate neural tube defect risk in the fetus.

4. While observing the electronic fetal heart rate monitor tracing for a client at 40 weeks of gestation in labor, a nurse should suspect a problem with the umbilical cord when she observes which of the following patterns?

• A. Early decelerations
• B. Accelerations
• C. Late decelerations
• D. Variable decelerations

Correct answer: D

Rationale: Variable decelerations can indicate umbilical cord compression, which is a concern that may arise due to the umbilical cord being compressed during labor. This compression can lead to reduced blood flow and oxygen delivery to the fetus, necessitating close monitoring and potentially interventions to alleviate the pressure on the cord. Early decelerations are typically benign and mirror the contractions, indicating fetal head compression. Accelerations are reassuring patterns that show a healthy response to fetal movement. Late decelerations are concerning as they suggest uteroplacental insufficiency, indicating potential oxygen deprivation to the fetus.

5. A client who is 6 hours postpartum and Rh-negative has an Rh-positive newborn. The client asks why an indirect Coombs test was ordered. Which of the following is an appropriate response by the healthcare provider?

• A. It determines if kernicterus will occur in the newborn.
• B. It detects Rh-negative antibodies in the newborn's blood.
• C. It detects Rh-positive antibodies in the mother's blood.
• D. It determines the presence of maternal antibodies in the newborn's blood.

Correct answer: C

Rationale: The indirect Coombs test is performed to detect Rh-positive antibodies in the mother's blood. In cases where the mother is Rh-negative and the baby is Rh-positive, the mother may develop antibodies against the baby's blood cells, which can lead to hemolytic disease of the newborn. Choice A is incorrect because kernicterus is a complication of severe jaundice, not directly assessed by the indirect Coombs test. Choice B is incorrect as the test aims to detect Rh-positive antibodies, not Rh-negative antibodies in the newborn's blood. Choice D is incorrect as the test is focused on detecting antibodies in the mother's blood, not the newborn's.
