Which nursing action is especially important for an SGA newborn?
- A. Promote bonding.
- B. Observe for and prevent dehydration.
- C. Observe for respiratory distress syndrom
- D. Prevent hypoglycemia with early and frequent feedings.
Correct Answer: D
Rationale: The correct answer is D because preventing hypoglycemia is crucial for Small for Gestational Age (SGA) newborns due to their decreased glycogen stores. Early and frequent feedings help maintain stable blood sugar levels. Option A, promoting bonding, is important for all newborns but not particularly crucial for SGA babies. Option B, preventing dehydration, is essential for all newborns but not specific to SGA. Option C, observing for respiratory distress syndrome, is important but not the most critical concern for SGA newborns.

Which is the most common etiology for pathological jaundice in an infant?
- A. ABO incompatibility
- B. Physiological
- C. Inherited pathology
- D. Birth trauma
Correct Answer: A
Rationale: The correct answer is A: ABO incompatibility. This is the most common etiology for pathological jaundice in an infant because it occurs when the baby's blood type is incompatible with the mother's, leading to the destruction of the baby's red blood cells and subsequent release of bilirubin, causing jaundice. Physiological jaundice (B) is common but typically resolves on its own without treatment. Inherited pathologies (C) such as genetic conditions may cause jaundice, but they are less common than ABO incompatibility. Birth trauma (D) can lead to jaundice in rare cases, but it is not the most common etiology.
A premature infant with respiratory distress syndrome (RDS) receives artificial surfactant. How does the nurse explain surfactant therapy to the parents?
- A. The drug keeps your infant from requiring too much sedation.
- B. Surfactant improves the ability of your infant’s lungs to exchange oxygen and carbon dioxide.
- C. Surfactant is used to reduce episodes of periodic tachycardia.
- D. Your infant needs this medication to fight a possible respiratory tract infection.
Correct Answer: B
Rationale: The correct answer is B because artificial surfactant improves the ability of the infant's lungs to exchange oxygen and carbon dioxide. Surfactant reduces surface tension in the alveoli, preventing collapse and helping with gas exchange. This explanation directly relates to the purpose of surfactant therapy in treating RDS. Choices A, C, and D are incorrect because they do not accurately describe the mechanism or purpose of surfactant therapy. Choice A is incorrect as surfactant does not affect sedation needs, choice C is incorrect as surfactant is not used to address tachycardia, and choice D is incorrect as surfactant is not used to treat respiratory tract infections.
Which infant is at greatest risk for developing hypoglycemia after birth?
- A. Severe small for gestational age infant
- B. Appropriate for gestational age infant
- C. Infant of a diabetic mother with maternal glucose control
- D. Cold-stressed term infant
Correct Answer: A
Rationale: The correct answer is A: Severe small for gestational age (SGA) infant, as they have limited glycogen stores and are at higher risk for hypoglycemia. SGA infants often have poor growth in utero, leading to decreased nutrient reserves. This puts them at increased risk for low blood sugar levels after birth.
Incorrect choices:
B: Appropriate for gestational age infants typically have adequate glycogen stores and are at lower risk for hypoglycemia.
C: Infants of diabetic mothers with good maternal glucose control are less likely to have hypoglycemia due to stable blood sugar levels in utero.
D: Cold-stressed term infants may have transient hypoglycemia, but they are not at the greatest risk compared to severe SGA infants.
The nurses in a NICU are concerned about the appropriate levels of oxygen therapy during the care of premature neonates. The nurses referenced an article by Newman (2014) titled, “Oxygen Saturation Limits and Evidence supporting the Targets.” On which evidence-based conclusion will the nurses develop guidelines?
- A. Oxygen saturation limits of 85% to 89% are effective.
- B. Oxygen saturation rates of 91% to 95% are effective.
- C. Infants are within saturation limits about 75% of the time.
- D. Oxygen saturation limits need to be between 87% to 94%.
Correct Answer: B
Rationale: The correct answer is B: Oxygen saturation rates of 91% to 95% are effective. This range is supported by the article by Newman (2014) as the optimal oxygen saturation levels for premature neonates. Here's the rationale:
1. The range of 91% to 95% falls within the typical target range for oxygen saturation in premature neonates, ensuring adequate oxygenation without the risk of hyperoxia or hypoxia.
2. Maintaining oxygen saturation within this range has been shown to improve outcomes and reduce the risk of complications in premature neonates.
3. The article by Newman likely provides evidence-based research supporting this specific range as the most effective for neonatal care.
In summary, choices A, C, and D are incorrect because they do not align with the evidence-based optimal oxygen saturation range for premature neonates as supported by the referenced article.
The nurse has access to the results of a karyotype sent out for their patient via an electronic medical record. The parents have accessed the results on their MyChart phone application and have asked the nurse what the results 45, X mean. What is the best response from the nurse?
- A. The results indicate your child may have Turner syndrome.
- B. Your results are 45, X; you will have to wait to talk with the geneticist.
- C. Your results indicate that your daughter has a serious lifelong disease.
- D. I’m not sure; I’ll call the provider.
Correct Answer: A
Rationale: The correct answer is A: The results indicate your child may have Turner syndrome. This is the best response because 45, X is the karyotype typically associated with Turner syndrome, a genetic condition where a female is missing part or all of one X chromosome. This response shows the nurse's knowledge of genetics and ability to interpret karyotype results accurately.
Summary of incorrect choices:
B: Your results are 45, X; you will have to wait to talk with the geneticist - This response delays providing crucial information to the parents and does not address their immediate concerns.
C: Your results indicate that your daughter has a serious lifelong disease - This choice is too vague and alarming, lacking specificity about the condition associated with the karyotype results.
D: I’m not sure; I’ll call the provider - This response shows a lack of knowledge on the nurse's part and does not offer any immediate information or reassurance to the parents.
