1. A nurse is caring for a newborn who is 6 hours old and has a bedside glucometer reading of 65 mg/dL. The newborn’s mother has type 2 diabetes mellitus. Which of the following actions should the nurse take?
- A. Obtain a blood sample for a serum glucose level
- B. Feed the newborn immediately
- C. Administer 50 mL of dextrose solution IV
- D. Reassess the blood glucose level prior to the next feeding
Correct answer: D
Rationale: A bedside glucometer reading of 65 mg/dL is within the normal range for a newborn. Reassessing the blood glucose level prior to the next feeding ensures ongoing monitoring without unnecessary intervention. Obtaining a blood sample for a serum glucose level (Choice A) is not necessary as the initial reading is normal. Feeding the newborn immediately (Choice B) may not be indicated and could lead to unnecessary interventions. Administering dextrose solution IV (Choice C) is not warranted as the glucose level is within the normal range and does not require immediate correction.
2. A premature infant with respiratory distress syndrome (RDS) receives artificial surfactant. How does the nurse explain surfactant therapy to the parents?
- A. “Surfactant improves the ability of your baby’s lungs to exchange oxygen and carbon dioxide.”
- B. “The drug keeps your baby from requiring too much sedation.”
- C. “Surfactant is used to reduce episodes of periodic apnea.”
- D. “Your baby needs this medication to fight a possible respiratory tract infection.”
Correct answer: A
Rationale: Artificial surfactant can be administered as an adjunct to oxygen and ventilation therapy for premature infants with respiratory distress syndrome (RDS). It helps improve respiratory compliance by aiding in the exchange of oxygen and carbon dioxide until the infant can produce enough surfactant naturally. The correct explanation to the parents would be that surfactant therapy enhances the baby’s lung function by facilitating the exchange of oxygen and carbon dioxide. Choice B is incorrect because surfactant therapy does not affect sedation needs. Choice C is inaccurate as surfactant is not used to reduce episodes of periodic apnea. Choice D is incorrect as surfactant is not administered to fight respiratory tract infections; it specifically targets improving lung function in RDS.
3. A nurse is reviewing laboratory results for a term newborn who is 24 hours old. Which of the following results require intervention by the nurse?
- A. WBC count 10,000/mm3
- B. Platelets 180,000/mm3
- C. Hemoglobin 20g/dL
- D. Glucose 20 mg/dL
Correct answer: D
Rationale: A glucose level of 20 mg/dL is critically low for a newborn and requires immediate intervention. Hypoglycemia in a newborn can lead to serious complications such as neurologic deficits. The normal range for glucose levels in a newborn is typically 40-60 mg/dL. Choices A, B, and C represent normal or acceptable values for a term newborn and do not require immediate intervention. A WBC count of 10,000/mm3, platelets of 180,000/mm3, and hemoglobin of 20g/dL are all within normal ranges for a term newborn and do not raise immediate concerns.
4. Rubella, also called German measles, is a viral infection passed from the mother to the fetus that can cause birth defects such as deafness, intellectual disabilities, blindness, and heart disease in the embryo.
- A. Rubella
- B. Syphilis
- C. Cystic fibrosis
- D. Phenylketonuria
Correct answer: A
Rationale: Rubella, also known as German measles, is a viral infection that can lead to severe birth defects when contracted by a mother during pregnancy. Rubella is the correct answer because it is specifically associated with causing birth defects such as deafness, intellectual disabilities, blindness, and heart disease in the embryo. Syphilis (Choice B) can be passed from mother to fetus but does not cause the mentioned birth defects associated with Rubella. Cystic fibrosis (Choice C) and Phenylketonuria (Choice D) are genetic conditions and not infections transmitted from mother to fetus, making them incorrect choices in this context.
5. Preconception counseling is crucial for the safe management of diabetic pregnancies. Which complication is commonly associated with poor glycemic control before and during early pregnancy?
- A. Frequent episodes of maternal hypoglycemia
- B. Congenital anomalies in the fetus
- C. Hydramnios
- D. Hyperemesis gravidarum
Correct answer: B
Rationale: Preconception counseling is essential as strict metabolic control before conception and in the early weeks of gestation helps reduce the risk of congenital anomalies. Frequent episodes of maternal hypoglycemia usually occur during the first trimester due to hormonal changes, affecting insulin production and use, rather than before conception. Hydramnios is more common in diabetic pregnancies, typically seen in the third trimester, not during early pregnancy. Hyperemesis gravidarum, although it may lead to hypoglycemic events, is related to decreased food intake and glucose transfer to the fetus, exacerbating hypoglycemia rather than being directly associated with poor glycemic control before and during early pregnancy.
