1. 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.
2. A healthcare provider is assessing a preterm newborn who is at 32 weeks of gestation. Which of the following finding should the healthcare provider expect?
- A. Minimal arm recoil
- B. Popliteal angle of less than 90°
- C. Creases over the entire sole
- D. Sparse lanugo
Correct answer: A
Rationale: When assessing a preterm newborn at 32 weeks of gestation, healthcare providers should expect minimal arm recoil. This finding is common in preterm infants due to lower muscle tone. Choice B, a popliteal angle of less than 90°, is incorrect for this age group. Creases over the entire sole (Choice C) typically develop at term age, not at 32 weeks of gestation. Sparse lanugo (Choice D) is a normal finding in preterm infants but is not specific to those at 32 weeks of gestation.
3. Twenty-year-old Jack is extremely tall and has very thick facial hair. Most of his male secondary sex characteristics are also more pronounced than men of his age. In this scenario, Jack is most likely:
- A. an XYY male.
- B. diagnosed with Klinefelter syndrome.
- C. an XXY male.
- D. diagnosed with Down syndrome.
Correct answer: A
Rationale: The correct answer is A: an XYY male. Individuals with XYY syndrome often exhibit increased height and more pronounced secondary male characteristics, such as thick facial hair. Choice B, Klinefelter syndrome (XXY), typically presents with less prominent male secondary sex characteristics due to the presence of an extra X chromosome. Choice C, XXY male, refers to Klinefelter syndrome, which does not align with the description of Jack having more pronounced male secondary sex characteristics. Choice D, Down syndrome, is caused by a trisomy of chromosome 21 and is not associated with the physical characteristics described in the scenario.
4. A nurse on an antepartum unit is reviewing the medical records for four clients. Which of the following clients should the nurse assess first?
- A. A client who has diabetes mellitus and an HbA1c of 5.8%
- B. A client who has preeclampsia and a creatinine level of 1.1 mg/dL
- C. A client who has hyperemesis gravidarum and a sodium level of 110 mEq/L
- D. A client who has placenta previa and a hematocrit of 36%
Correct answer: C
Rationale: A sodium level of 110 mEq/L is critically low and can indicate severe dehydration and electrolyte imbalance, requiring immediate intervention.
5. Which procedure is used to detect neural tube defects such as spina bifida and certain chromosomal abnormalities?
- A. Artificial insemination
- B. Amniocentesis
- C. Endometriosis
- D. Alpha-fetoprotein (AFP) assay
Correct answer: D
Rationale: The correct answer is the Alpha-fetoprotein (AFP) assay. This blood test measures the level of AFP in a pregnant woman's blood, aiding in the detection of neural tube defects and certain chromosomal abnormalities in the fetus. Choice A, artificial insemination, is a method used to facilitate fertilization and is not related to detecting fetal abnormalities. Choice B, amniocentesis, involves collecting amniotic fluid for genetic testing, not directly measuring AFP levels. Choice C, endometriosis, is a medical condition involving abnormal tissue growth and is not a procedure for detecting fetal abnormalities. Therefore, the Alpha-fetoprotein (AFP) assay is the most appropriate option for detecting neural tube defects such as spina bifida and certain chromosomal abnormalities.
