Nursing Elites

1. A client is scheduled for a cesarean birth based on fetal lung maturity. Which finding indicates that the fetal lungs are mature?

• A. Absence of Phosphatidylglycerol (PG)
• B. Biophysical profile score of 8
• C. Lecithin/sphingomyelin (L/S) ratio of 2:1
• D. Reactive nonstress test

Correct answer: C

Rationale: An L/S ratio of 2:1 indicates fetal lung maturity, as it signifies the presence of surfactant in the amniotic fluid, which helps with lung expansion and prevents collapse at the end of expiration. The absence of PG indicates immaturity of the fetal lungs, as PG appears in the amniotic fluid during the later stages of lung maturation. Biophysical profile scores and nonstress tests are assessments of fetal well-being and do not directly indicate fetal lung maturity. Therefore, choice C is the correct answer.

2. When assessing newborn reflexes, what action should be taken to elicit the Moro reflex?

• A. Perform a sharp hand clap near the infant.
• B. Hold the newborn vertically allowing one foot to touch the table surface.
• C. Place a finger at the base of the newborn's toes.
• D. Turn the newborn's head quickly to one side.

Correct answer: A

Rationale: The correct answer is A: Perform a sharp hand clap near the infant. The Moro reflex, also known as the startle reflex, is elicited by a sudden stimuli such as a sharp hand clap near the infant. This reflex is characterized by the infant's arms extending and then flexing with a distinctive 'startle' motion. It is a normal and expected reflex in newborns, typically disappearing by 3-6 months of age. Choices B, C, and D are incorrect because they do not elicit the Moro reflex; holding the newborn vertically (choice B) or placing a finger at the base of the newborn's toes (choice C) are associated with other reflexes, while turning the newborn's head quickly to one side (choice D) is related to the tonic neck reflex.

3. A client has severe preeclampsia and is receiving magnesium sulfate IV. Which of the following findings should the nurse identify and report as signs of magnesium sulfate toxicity? (Select all that apply)

• A. Respirations less than 12/min
• B. Urinary output less than 25 mL/hr
• C. Decreased level of consciousness
• D. All of the above

Correct answer: D

Rationale: Signs of magnesium sulfate toxicity include respirations less than 12/min, urinary output less than 25 mL/hr, and decreased level of consciousness. These signs indicate potential overdose of magnesium sulfate and require immediate attention to prevent further complications. Reporting these signs promptly is crucial to ensure the client's safety and well-being. Choice D, 'All of the above,' is the correct answer as all the listed findings are indicative of magnesium sulfate toxicity. Choices A, B, and C individually represent different signs of toxicity, making them incorrect on their own. Therefore, the nurse should be vigilant in identifying and reporting all these signs to prevent adverse outcomes.

4. A nurse is teaching clients in a prenatal class about the importance of taking folic acid during pregnancy. The nurse should instruct the clients to consume an adequate amount of folic acid from various sources to prevent which of the following fetal abnormalities?

• A. Neural tube defect
• B. Trisomy 21
• C. Cleft lip
• D. Atrial septal defect

Correct answer: A

Rationale: The nurse should educate clients that inadequate folic acid intake is associated with an increased risk of neural tube defects in newborns. Consuming an adequate amount of folic acid from sources like fortified cereals, oranges, artichokes, liver, broccoli, and asparagus can help prevent this serious fetal abnormality. Trisomy 21 (Choice B) is caused by an extra chromosome 21 and is not preventable by folic acid intake. Cleft lip (Choice C) and atrial septal defect (Choice D) are not directly linked to folic acid intake during pregnancy.

5. A caregiver is being taught about bottle feeding a newborn. Which of the following statements by the caregiver indicates a need for further instruction?

• A. I will keep the baby's head elevated while feeding.
• B. I will allow the baby to burp several times during each feeding.
• C. I will tilt the bottle to prevent air from entering as the baby sucks.
• D. My baby will have soft, formed yellow stools.

Correct answer: C

Rationale: Tilting the bottle to prevent air from entering as the baby sucks can lead to the baby swallowing air, causing discomfort and potential issues like colic or gas. The correct way to bottle-feed a newborn is by ensuring that the nipple is always filled with milk to avoid air intake, which can lead to problems. Keeping the baby's head elevated while feeding helps prevent choking, allowing the baby to burp several times during each feeding helps release swallowed air, and soft, formed yellow stools indicate a healthy digestion process in newborns.
