The nurse is explaining the process of cell division during the preembryonic period to a group of nursing students. Which statement best describes the characteristics of the morula?
- A. Fertilized ovum before mitosis begins
- B. Double layer of cells that becomes the placenta
- C. Flattened, disk-shaped layer of cells within a fluid-filled sphere
- D. Solid ball composed of the first cells formed after fertilization
Correct Answer: D
Rationale: The correct answer is D because a morula is a solid ball composed of the first cells formed after fertilization. During the preembryonic period, the zygote undergoes several rounds of cell division to form a morula, which is a compact cluster of cells. A: is incorrect as a fertilized ovum is a zygote, not a morula. B: is incorrect as the double layer of cells that becomes the placenta is the bilaminar germ disc, not the morula. C: is incorrect as a flattened, disk-shaped layer of cells within a fluid-filled sphere describes the blastocyst, not the morula. Thus, the characteristics of a morula being a solid ball composed of the first cells formed after fertilization make option D the correct choice.

The nurse is counseling a couple who just learned their 16-week fetus tested positive for a serious genetic disorder. Which action by the nurse is inappropriate upon learning that the couple plan to continue the pregnancy?
- A. Determine whether termination is still a consideration.
- B. Explain they will experience grief, which is normal.
- C. Provide additional information about the disorder.
- D. Refer them to a disorder-specific support group.
Correct Answer: A
Rationale: The correct answer is A because it respects the couple's decision-making autonomy. The nurse should support their choice to continue the pregnancy without suggesting termination. Providing information, emotional support, and connecting them with a support group are appropriate actions. It is crucial to respect the couple's decision and provide compassionate care regardless of their choice. The other choices are incorrect because they may undermine the couple's autonomy and may not be aligned with their wishes.
Identify the health care provided during a home birth. Select all that apply.
- A. labor support
- B. trained birth attendant
- C. neonatal intensive care
- D. breast-feeding assistance
Correct Answer: C
Rationale: The correct answer is C: neonatal intensive care. This is because during a home birth, neonatal intensive care is not provided as it requires specialized medical equipment and expertise typically only available in hospitals. Labor support (A) and trained birth attendant (B) are essential for home births. Breastfeeding assistance (D) may be provided post-birth but is not a defining feature of care during a home birth.
The nurse is providing education to a pregnant person regarding the nausea and vomiting of pregnancy. Identify the relief measures the nurse would discuss. Select all that apply.
- A. avoid dairy products
- B. avoid strong odors
- C. drink fluids between meals
- D. drink sweet fluids
Correct Answer: A
Rationale: The correct answer is A: avoid dairy products. This is because dairy products can exacerbate nausea in some pregnant individuals due to their high fat content. Avoiding dairy products can help reduce nausea symptoms.
Rationale:
1. Avoiding dairy products: High fat content in dairy products can trigger nausea in some pregnant individuals.
2. Avoid strong odors: While strong odors can trigger nausea, it is not a specific relief measure for nausea and vomiting of pregnancy.
3. Drink fluids between meals: Staying hydrated is important, but drinking fluids between meals is not a specific relief measure for nausea and vomiting of pregnancy.
4. Drink sweet fluids: While some pregnant individuals find relief from nausea by consuming sweet fluids, it is not a universal recommendation and may not work for everyone.
The nurse is assessing a newborn immediately after birth. After assigning the first Apgar score
of 9, the nurse notes two vessels in the umbilical cord. What is the nurse’s next action?
- A. Assess for other abnormalities of the infant.
- B. Note the assessment finding in the infant’s chart.
- C. Notify the health care provider of the assessment finding.
- D. Call for the neonatal resuscitation team to attend the infant immediately.
Correct Answer: A
Rationale: The correct answer is A. The nurse should assess for other abnormalities of the infant because the presence of two vessels in the umbilical cord (a condition known as a two-vessel cord) may be associated with other congenital anomalies. By assessing for other abnormalities, the nurse can identify any potential issues that may require immediate intervention or further evaluation. This proactive approach ensures the newborn's well-being and allows for timely management of any additional concerns.
Summary of other choices:
B: Noting the finding in the chart is important but does not address the immediate need to assess for other abnormalities.
C: Notifying the health care provider is important, but assessing for other abnormalities should be the nurse's initial priority.
D: Calling for the neonatal resuscitation team is not necessary based solely on the presence of a two-vessel cord; further assessment is needed before determining the need for resuscitation.
As relates to the structure and function of the placenta, the maternity nurse should be aware that:
- A. As the placenta widens, it gradually thins to allow easier passage of air and nutrients.
- B. As one of its early functions, the placenta acts as an endocrine gland.
- C. The placenta is able to keep out most potentially toxic substances such as cigarette smoke to which the mother is exposed.
- D. Optimal blood circulation is achieved through the placenta when the woman is lying on her back or standing.
Correct Answer: B
Rationale: The placenta produces hormones necessary to maintain the pregnancy.
