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. The mother of a breastfeeding 24-hour old infant is very concerned about the techniques involved in breastfeeding. She calls the nurse with each feeding to seek reassurance that she is doing it right. She tells the nurse, "Now my daughter is not getting enough to eat." Which response would be best for the nurse to make?
- A. Feed your baby hourly until you feel confident that your child is receiving enough milk.
- B. Don't worry, soon your milk will come in, and you will feel how full your breasts are.
- C. Since you are so concerned, you should probably supplement breastfeeding with formula.
- D. If your baby's urine is straw-colored, she's getting enough milk.
Correct answer: D
Rationale: Reassuring the mother that the baby's urine color can be an indicator of adequate hydration can help her feel more confident in her breastfeeding.
3. Individuals with Klinefelter syndrome produce:
- A. less estrogen than normal males.
- B. less testosterone than normal males.
- C. less adenine than normal males.
- D. less thymine than normal males.
Correct answer: B
Rationale: Individuals with Klinefelter syndrome have an extra X chromosome (XXY), leading to reduced production of testosterone, the primary male sex hormone. This deficiency can result in various physical and developmental characteristics associated with the syndrome. Estrogen levels may actually be relatively elevated due to the imbalance between testosterone and estrogen. Choices C and D are incorrect as adenine and thymine are nucleotide bases found in DNA and are not related to hormone production.
4. Genotypes are solely based on genetic information.
- A. TRUE
- B. FALSE
- C. Sometimes
- D. Never
Correct answer: B
Rationale: The correct answer is B - FALSE. Genotypes are solely based on genetic information and do not reflect environmental influences. Phenotypes, on the other hand, result from the interaction of genetic and environmental factors. Choices A, C, and D are incorrect because genotypes are not influenced by environmental factors, and they are determined by an individual's genetic makeup.
5. Rh incompatibility occurs when an Rh-negative woman is carrying an Rh-positive fetus.
- A. TRUE
- B. FALSE
- C. Sometimes
- D. Never
Correct answer: B
Rationale: Rh incompatibility occurs when an Rh-negative woman is carrying an Rh-positive fetus, not the other way around. Therefore, the statement that an Rh-positive woman is carrying an Rh-negative fetus is incorrect. Rh incompatibility can lead to hemolytic disease of the newborn, where maternal antibodies attack the fetal red blood cells. Choice A is incorrect because the statement is false. Choice C is incorrect as Rh incompatibility has a clear cause and effect relationship. Choice D is incorrect as Rh incompatibility can occur, but it depends on the Rh status of the mother and fetus.
