At which point in the pregnancy can a woman first feel fetal movement (quickening)?
- A. 12 weeks
- B. 16 weeks
- C. 20 weeks
- D. 24 weeks
Correct Answer: C
Rationale: The correct answer is C (20 weeks) because quickening, the first perception of fetal movement by the mother, typically occurs around this time. At 20 weeks, the fetus is large enough for its movements to be noticeable to the mother. Before 20 weeks, the fetus is too small and the movements are not strong enough to be felt. Choices A, B, and D are incorrect because they are too early in the pregnancy for the mother to feel fetal movement. By 20 weeks, the fetus has developed enough for the mother to perceive its movements, making option C the correct answer.

What is an example of a statement by the patient that indicates effective teaching by the nurse about methods to improve fertility?
- A. “Caffeine does not affect my fertility.”
- B. “I should start taking prenatal vitamins to increase my chances of conception.”
- C. “My partner should avoid any exercise while we are trying to conceive to avoid damaging the sperm.”
- D. “Smoking can increase my risk of miscarriage.”
Correct Answer: D
Rationale: The correct answer is D because it accurately reflects the nurse's teaching on fertility. Smoking is known to have negative effects on fertility and can increase the risk of miscarriage. This statement shows that the patient has understood the information provided by the nurse regarding factors that could impact fertility.
A is incorrect because caffeine can actually affect fertility. B is incorrect because while taking prenatal vitamins is beneficial, it does not directly address fertility improvement. C is incorrect as exercise is generally beneficial for fertility and does not necessarily harm sperm.
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 would anticipate that a patient with elevated levels of which hormone would require radiologic imaging of the brain?
- A. TSH
- B. prolactin
- C. progesterone
- D. FSH
Correct Answer: B
Rationale: The correct answer is B: prolactin. Elevated prolactin levels can indicate a pituitary tumor, which may require brain imaging. TSH, progesterone, and FSH are not typically associated with the need for brain imaging. TSH is related to thyroid function, progesterone to the menstrual cycle, and FSH to reproductive health. Prolactin is the hormone primarily associated with lactation and can be elevated due to various reasons, including pituitary tumors. Therefore, in a patient with elevated prolactin levels, brain imaging is necessary to assess for the presence of a pituitary tumor.
Which immunoglobulin is the only one that crosses the placenta during pregnancy?
- A. IgG
- B. IgA
- C. IgM
- D. IgD
Correct Answer: A
Rationale: The correct answer is A: IgG. IgG is the only immunoglobulin that can cross the placenta due to its small size and ability to bind to the neonatal Fc receptor. This transfer provides passive immunity to the fetus, protecting it from infections. IgA primarily functions in mucosal immunity and is found in secretions like breast milk. IgM is too large to cross the placenta and is mainly produced in response to acute infections. IgD is primarily found on the surface of B cells and functions in the activation of these cells.
Which statement best describes the changes that occur during the fetal period of development?
- A. Maturation of organ systems
- B. Development of basic organ systems
- C. Resistance of organs to damage from external agents
- D. Development of placental oxygen–carbon dioxide exchange
Correct Answer: A
Rationale: The correct answer is A because during the fetal period, organ systems continue to mature and develop to become fully functional. This includes refining the structures and functions of organs that have already been formed during the embryonic period. Option B is incorrect because basic organ systems are already formed during the embryonic period. Option C is incorrect as organs are still susceptible to damage during the fetal period. Option D is incorrect because the development of placental oxygen–carbon dioxide exchange primarily occurs during the early stages of pregnancy, not specifically during the fetal period.
