Nursing Elites

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. Which of the following pairs share 100% of their genes?

• A. Biovular twins
• B. Fraternal twins
• C. Dizygotic (DZ) twins
• D. Monozygotic (MZ) twins

Correct answer: D

Rationale: The correct answer is Monozygotic (MZ) twins. Monozygotic twins, also known as identical twins, share 100% of their genes because they originate from the same fertilized egg that splits into two. Fraternal twins (choice B), also known as dizygotic (DZ) twins (choice C), result from two separate fertilized eggs and share approximately 50% of their genes. Biovular twins (choice A) is not a term used in genetics and does not describe a type of twinning.

3. What is the central layer of the embryo from which the bones and muscles develop?

• A. neural tube
• B. mesoderm
• C. ectoderm
• D. umbilical cord

Correct answer: B

Rationale: The correct answer is mesoderm. The mesoderm is the middle layer of the embryo that gives rise to the bones, muscles, and other connective tissues. The neural tube (choice A) develops into the nervous system, not bones and muscles. The ectoderm (choice C) forms the skin and nervous system, not bones and muscles. The umbilical cord (choice D) is a structure that connects the developing fetus to the placenta; it is not a layer of the embryo that gives rise to bones and muscles.

4. A client is 4 hours postpartum and is experiencing hypovolemic shock. Which of the following actions should the nurse take?

• A. Administer indomethacin
• B. Insert a second 22-gauge IV catheter.
• C. Insert an indwelling urinary catheter.
• D. Administer oxygen at 4L/min via nasal cannula.

Correct answer: D

Rationale: In hypovolemic shock, there is decreased oxygen delivery to tissues. Administering oxygen at 4L/min via nasal cannula can help improve oxygenation and support tissue perfusion. Indomethacin (Choice A) is a nonsteroidal anti-inflammatory drug and is not indicated in the management of hypovolemic shock. Inserting a second 22-gauge IV catheter (Choice B) may be necessary for fluid resuscitation, but oxygen administration takes precedence. Inserting an indwelling urinary catheter (Choice C) may be considered for monitoring urinary output, but it is not the priority action in managing hypovolemic shock.

5. A new mother who is a lacto-ovo vegetarian plans to breastfeed her infant. Which information should the nurse provide prior to discharge?

• A. Continue prenatal vitamins with B12 while breastfeeding
• B. Avoid using Lanolin-based nipple cream or ointment
• C. Offer iron-fortified supplemental formula daily
• D. Weigh the baby weekly to evaluate the newborn's growth

Correct answer: A

Rationale: The correct answer is A: 'Continue prenatal vitamins with B12 while breastfeeding.' Vitamin B12 is crucial for lacto-ovo vegetarian mothers to prevent deficiencies in both the mother and the infant. Choice B is incorrect as Lanolin-based nipple cream is safe for use during breastfeeding. Choice C is not necessary unless there are specific indications for iron supplementation. Choice D, weighing the baby weekly, is important for monitoring growth but not specifically related to the mother's diet.
