1. Which statement about the human immunodeficiency virus (HIV) is true?

A. About 30 percent of all new HIV infections affect women.
B. In South Africa, 30 percent of all pregnant women are HIV-positive.
C. About 30 percent of new HIV infections occur in developing countries.
D. Untreated HIV-infected mothers pass the virus to the fetus 30 percent of the time.

Correct answer: B

Rationale: The correct answer is B: 'In South Africa, 30 percent of all pregnant women are HIV-positive.' This statement is true as South Africa has a high prevalence of HIV among pregnant women, emphasizing the need for interventions to prevent mother-to-child transmission. Choices A, C, and D are incorrect. Choice A is inaccurate as women account for more than 50% of new HIV infections globally. Choice C is misleading as the majority of new HIV infections actually occur in sub-Saharan Africa, not just developing countries. Choice D is also incorrect as without treatment, the risk of mother-to-child transmission is higher than 30%.

2. Which statement about epidural analgesia is true?

A. It numbs the entire lower half of the body.
B. It limits pain reduction to the pelvic region.
C. It strengthens uterine contractions.
D. It shortens the length of labor.

Correct answer: B

Rationale: The correct statement about epidural analgesia is that it limits pain reduction to the pelvic region by blocking nerve signals from that specific area, providing pain relief during labor and delivery. Choice A is incorrect because epidural analgesia does not numb the entire lower half of the body. Choice C is incorrect because epidural analgesia does not strengthen uterine contractions; in fact, it may sometimes weaken them. Choice D is incorrect because epidural analgesia does not shorten the length of labor; it can sometimes prolong labor.

3. Kathryn would like to give birth in a medical facility that permits maternal control over labor and delivery, including choice of delivery positions, and allows the presence of family members and friends. Kathryn should consider giving birth at a __________.

A. private home
B. local hospital
C. doula center
D. freestanding birth center

Correct answer: D

Rationale: Kathryn should consider giving birth at a freestanding birth center. Freestanding birth centers provide a setting where women can have more control over their labor and delivery experience, including the choice of delivery positions, the presence of family members and friends, and involvement in decision-making throughout the process. These centers offer a more home-like environment compared to hospitals while still providing access to medical support if needed. Choices A (private home) and B (local hospital) do not necessarily guarantee the level of control and facilities Kathryn seeks. While a doula center (Choice C) can provide additional support during labor, it may not offer the same level of medical facilities and control over the birthing process as a freestanding birth center.

4. During the third stage of labor, __________.

A. the cervix thins to nothing
B. uterine contractions begin
C. the placenta is delivered
D. the baby is born

Correct answer: C

Rationale: During the third stage of labor, the correct answer is C, the placenta is delivered. This stage occurs after the baby is born and involves the expulsion of the placenta from the uterus. Choice A is incorrect because the thinning of the cervix to nothing typically occurs during the first stage of labor. Choice B is incorrect as uterine contractions usually begin during the first stage of labor to help with the dilation of the cervix. Choice D is incorrect because the baby is typically born in the second stage of labor, not the third.

5. T. Berry Brazelton's Neonatal Behavioral Assessment Scale (NBAS) evaluates a newborn's __________.

A. risk for developmental problems
B. ability to comply with parental commands and responsiveness to touch
C. reflexes, muscle tone, state changes, and responsiveness to stimulation
D. heart rate, respiratory effort, reflex irritability, muscle tone, and color

Correct answer: C

Rationale: T. Berry Brazelton's Neonatal Behavioral Assessment Scale (NBAS) evaluates a newborn's reflexes, muscle tone, state changes, and responsiveness to stimulation. This assessment helps healthcare providers understand the newborn's behavioral responses and capabilities in various areas, providing valuable insights into their overall development and well-being. Choices A, B, and D are incorrect because the NBAS focuses on assessing the newborn's behavioral responses and capabilities, rather than their risk for developmental problems, compliance with commands, or physiological parameters like heart rate and respiratory effort.
