Human Growth and Development Final Exam Answers
1. According to psychosexual theory, what is crucial for healthy personality development?
- A. Children actively construct knowledge as they manipulate and explore the world.
- B. Directly observable events are the appropriate focus of psychological study.
- C. How parents manage their child's sexual and aggressive drives in the first few years.
- D. The ego makes a positive contribution to development, acquiring attitudes and skills.
Correct answer: C
Rationale: According to psychosexual theory, developed by Sigmund Freud, how parents manage their child's sexual and aggressive drives in the first few years is crucial for healthy personality development. This theory suggests that personality development is heavily influenced by a child's experiences during early stages of development, particularly related to handling sexual and aggressive impulses. Choices A, B, and D are incorrect as they do not align with the core principles of psychosexual theory, which focuses on the importance of early childhood experiences, especially in the context of sexual and aggressive drives.
2. Currently, the most widely used potent teratogen is __________.
- A. aspirin
- B. diethylstilbestrol (DES)
- C. thalidomide
- D. isotretinoin
Correct answer: D
Rationale: The correct answer is D, isotretinoin. Isotretinoin is a medication commonly used to treat severe acne, but it is a potent teratogen, meaning it can cause severe birth defects if taken during pregnancy. Aspirin (choice A) is not a widely used potent teratogen. Diethylstilbestrol (DES) (choice B) was a known teratogen, but it is not currently widely used. Thalidomide (choice C) was another historical teratogen, but it is also not currently widely used. Therefore, isotretinoin is the most relevant answer as it is a commonly used medication that poses a high risk of birth defects if used during pregnancy.
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 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.
5. In the last weeks of pregnancy, __________.
- A. the fetus usually loses weight
- B. most fetuses assume an upside-down position
- C. fetal growth increases dramatically
- D. the fetus relies on its own well-developed immune system
Correct answer: B
Rationale: In the last weeks of pregnancy, most fetuses assume an upside-down position known as the head-down position or vertex presentation. This position is ideal for a smoother labor and delivery process as it helps the baby move through the birth canal. Fetal growth has already slowed down at this stage, so option C is incorrect. Option A is inaccurate as the fetus typically gains weight in the final weeks. Option D is incorrect because the fetus relies on the mother's immune system while in the womb.
