1. Maryann is pregnant and works in a smoke-filled environment. What can you tell her about passive smoking?

A. The negative effects of smoking are only evident in children born to heavy smokers.
B. Passive smoking is related to low birth weight, infant death, and childhood respiratory illnesses.
C. Smoke-filled environments are harmful to expectant mothers, but not to their unborn children.
D. The effects of passive smoking are not yet known.

Correct answer: B

Rationale: Passive smoking, also known as secondhand smoke, can have harmful effects on pregnancies. Research has shown that exposure to smoke-filled environments during pregnancy is linked to low birth weight, infant death, and childhood respiratory illnesses. Pregnant women should avoid exposure to secondhand smoke to protect the health of their unborn babies. Choice A is incorrect because passive smoking affects both the mother and the unborn child, not just children born to heavy smokers. Choice C is incorrect as it underestimates the risks of smoke-filled environments on unborn children. Choice D is incorrect as research has already established the harmful effects of passive smoking on pregnancies.

2. Basic emotions __________.

A. appear in the middle of the second year
B. are universal in humans
C. are found only among humans
D. involve injury to our sense of self

Correct answer: B

Rationale: Basic emotions like happiness, sadness, and anger are universal across humans, meaning they are experienced by people worldwide regardless of cultural differences. These emotions are not limited to a specific group of individuals or exclusive to humans; they are observed in various species. Choice A is incorrect because basic emotions actually appear early in life, not specifically in the middle of the second year. Choice C is incorrect as basic emotions are not exclusive to humans but are observed in other animals as well. Choice D is incorrect because basic emotions do not necessarily involve injury to our sense of self, but rather represent fundamental and instinctual feelings that are part of human nature.

3. Which statement about the Nurse-Family Partnership is true?

A. It is an international program to reduce the risk of teratogens.
B. One of its goals is to promote competent early caregiving.
C. It is a series of childbirth classes offered at many U.S. hospitals.
D. It provides family planning and genetic counseling to couples.

Correct answer: B

Rationale: The statement that is true about the Nurse-Family Partnership is that one of its goals is to promote competent early caregiving. The program provides support and guidance to first-time mothers to help them develop their caregiving skills and promote healthy child development. Choice A is incorrect because the program focuses on promoting healthy child development and supporting mothers, not specifically reducing the risk of teratogens. Choice C is incorrect because the Nurse-Family Partnership is not a series of childbirth classes but a program that involves home visits and support. Choice D is incorrect because the program's main focus is on supporting mothers in caregiving and child development, not primarily on family planning and genetic counseling.

4. Lanugo ________.

A. permits food and oxygen to reach the organism
B. provides the fetus a cushion against jolts caused by the mother's movements
C. helps regulate the fetus's body temperature
D. helps the vernix stick to the skin

Correct answer: D

Rationale: Lanugo helps the vernix stick to the skin. Vernix is a waxy substance that covers the fetus's skin during pregnancy. Lanugo is a fine, downy hair that helps to anchor the vernix to the skin, providing protection and nourishment to the developing fetus. Choices A, B, and C are incorrect as they do not accurately describe the role of lanugo in prenatal development.

5. Dana is pregnant with her first child and wonders how much weight she should gain during the pregnancy. You should recommend a healthy diet that results in a weight gain of __________ pounds.

A. 10 to 15
B. 15 to 20
C. 25 to 30
D. 35 to 40

Correct answer: C

Rationale: The recommended weight gain during pregnancy depends on the pre-pregnancy weight of the mother. For a woman with a normal pre-pregnancy BMI, the recommended weight gain is typically between 25 to 30 pounds. This range is considered healthy to support the growth and development of the baby while also maintaining the mother's health. Choices A, B, and D are incorrect as they represent weight gain ranges that are either too low or too high for a woman with a normal pre-pregnancy BMI, which could pose health risks for both the mother and the baby. It is crucial to adhere to healthcare professionals' guidelines to ensure a healthy pregnancy and birth outcome.
