1. The term teratogen refers to __________.

• A. any environmental agent that causes damage during the prenatal period
• B. a limited time span during which a part of the body is biologically prepared to develop rapidly
• C. a rapid period of prenatal neurological development
• D. a synthetic hormone used to prevent miscarriage

Correct answer: A

Rationale: The correct answer is A: 'any environmental agent that causes damage during the prenatal period.' A teratogen is any substance or factor that can cause harm to the developing fetus during pregnancy. Choice B is incorrect because it describes a critical period, not a teratogen. Choice C is incorrect as it refers to a specific period of development, not a teratogen. Choice D is incorrect because it describes a synthetic hormone, not a teratogen.

2. During pregnancy, the placenta __________.

• A. forms in the second trimester of pregnancy
• B. encloses the developing organism in amniotic fluid
• C. contains one large vein that delivers nutrients to the embryo
• D. delivers food and oxygen to the developing organism

Correct answer: D

Rationale: The placenta delivers food and oxygen to the developing organism during pregnancy. It is a temporary organ that forms in the first trimester of pregnancy. Choice A is incorrect as the placenta forms in the first trimester, not the second trimester. Choice B is incorrect as the amniotic sac, not the placenta, encloses the developing organism in amniotic fluid. Choice C is incorrect as the placenta contains blood vessels (arteries and veins) that deliver nutrients to the embryo, not just one large vein.

3. Mothers who __________ have fewer birth complications and shorter labors.

• A. choose cesarean delivery
• B. give birth at home
• C. are supported by a trained companion during childbirth
• D. are administered epidural analgesia during childbirth

Correct answer: C

Rationale: According to research, mothers who are supported by a trained companion during childbirth have fewer birth complications and shorter labors. This support can reduce stress and anxiety levels, provide comfort and encouragement, and help the mother feel more in control during labor and delivery. Overall, having a trained companion present can contribute to a more positive childbirth experience for the mother. Choices A, B, and D are incorrect because they do not align with the research findings that specifically highlight the benefits of having a trained companion during childbirth.

4. Which of the following is a self-conscious emotion?

• A. guilt
• B. happiness
• C. interest
• D. fear

Correct answer: A

Rationale: The correct answer is A, guilt. Guilt is a self-conscious emotion that involves reflecting on one's actions and feeling remorse. Self-conscious emotions are those that require self-reflection and self-evaluation. Choices B, C, and D are not self-conscious emotions. Happiness and fear are not self-conscious emotions as they do not necessarily involve self-reflection. Interest is not a self-conscious emotion but rather a feeling of curiosity or attraction towards something.

5. Chinara is Rh-negative and Savon, her first child, is Rh-positive. Chinara's doctor will probably __________.

• A. give Savon a vaccine to prevent heart damage and intellectual disabilities
• B. advise Chinara not to have another child due to Rh incompatibility
• C. give Chinara a vaccine to prevent the buildup of antibodies to the foreign Rh protein
• D. do nothing because firstborn children are not affected by Rh incompatibility

Correct answer: C

Rationale: Chinara is Rh-negative and Savon, her first child, is Rh-positive. This presents a risk of Rh incompatibility in future pregnancies. To prevent the buildup of antibodies to the foreign Rh protein and protect future pregnancies, Chinara's doctor will likely give her a vaccine known as RhoGAM to prevent her immune system from reacting to Rh-positive blood cells. This vaccine helps to minimize the risks of complications in subsequent pregnancies. Choice A is incorrect because the vaccine is given to the mother, not the child. Choice B is incorrect as advising against having more children is not a typical response when preventive measures are available. Choice D is incorrect because all subsequent pregnancies are at risk of Rh incompatibility, not just the firstborn child.
