Nursing Elites

1. During preterm labor, a client is scheduled for an amniocentesis. The nurse should review which of the following tests to assess fetal lung maturity?

• A. Alpha-fetoprotein (AFP)
• B. Lecithin/sphingomyelin (L/S) ratio
• C. Kleihauer-Betke test
• D. Indirect Coombs' test

Correct answer: B

Rationale: The Lecithin/sphingomyelin (L/S) ratio is a test used to evaluate fetal lung maturity. An L/S ratio greater than 2:1 indicates fetal lung maturity. This test helps in determining the risk of respiratory distress syndrome in the newborn. Alpha-fetoprotein (AFP) is used in screening for neural tube defects, not for assessing lung maturity. The Kleihauer-Betke test is used to detect fetal-maternal hemorrhage, not fetal lung maturity. The Indirect Coombs' test is used to identify the presence of antibodies in the mother's blood that could attack fetal red blood cells, not for assessing lung maturity.

2. 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.

3. During a vaginal exam on a client in labor who reports severe pressure and pain in the lower back, a nurse notes that the fetal head is in a posterior position. Which of the following is the best nonpharmacological intervention for the nurse to perform to relieve the client's discomfort?

• A. Back rub
• B. Counter-pressure
• C. Playing music
• D. Foot massage

Correct answer: B

Rationale: In cases where the fetus is in a posterior position causing severe pressure and pain in the lower back during labor, applying counter-pressure is the most effective nonpharmacological intervention. Counter-pressure helps lift the fetal head off the spinal nerve, offering relief to the client. This technique is evidence-based and recommended to alleviate discomfort associated with a posterior fetal position. Choices A, C, and D are not as effective in this situation. While a back rub or playing music may provide some comfort, they do not directly address the issue caused by the fetal head's position. Similarly, a foot massage may offer relaxation but may not significantly relieve the specific discomfort arising from the posterior fetal position and the associated lower back pain.

4. A nurse is caring for a preterm newborn who is in an incubator to maintain a neutral thermal environment. The father of the newborn asks the nurse why this is necessary. Which of the following responses should the nurse make?

• A. Preterm newborns have a smaller body surface area than normal newborns.
• B. The added brown fat layer in a preterm newborn reduces his ability to generate heat.
• C. Preterm newborns lack adequate temperature control mechanisms.
• D. The heat in the incubator rapidly dries the sweat of preterm newborns.

Correct answer: C

Rationale: The correct answer is C because preterm newborns have immature temperature regulation mechanisms, making it difficult for them to maintain their body temperature. An incubator helps maintain a stable thermal environment. Choice A is incorrect as the body surface area is not the primary reason for needing an incubator. Choice B is incorrect because brown fat in preterm newborns actually helps generate heat. Choice D is incorrect as the purpose of the incubator is not to dry sweat but to regulate the newborn's temperature.

5. A client is in labor, and a nurse observes late decelerations on the electronic fetal monitor. What should the nurse identify as the first action that the registered nurse should take?

• A. Assist the client into the left-lateral position
• B. Apply a fetal scalp electrode
• C. Insert an IV catheter
• D. Perform a vaginal exam

Correct answer: A

Rationale: Late decelerations indicate uteroplacental insufficiency. The initial action should be to assist the client into the left-lateral position to optimize maternal blood flow and oxygenation to the fetus, thereby improving uteroplacental blood flow and fetal oxygenation. This position helps reduce pressure on the vena cava, enhancing blood return to the heart and improving circulation to the placenta. Applying a fetal scalp electrode (Choice B) is not the first action indicated for late decelerations. Inserting an IV catheter (Choice C) and performing a vaginal exam (Choice D) are not primary interventions for addressing late decelerations related to uteroplacental insufficiency.
