Human Growth and Development Final Exam Answers
1. During the second month of pregnancy, __________.
- A. the umbilical cord first appears as a primitive body stalk
- B. touch sensitivity extends to most of the body
- C. the heart develops separate chambers
- D. the heartbeat can be heard through a stethoscope
Correct answer: C
Rationale: During the second month of pregnancy, the heart of the developing fetus begins to develop separate chambers, forming the structure necessary for a fully functioning heart. This is a significant milestone in the prenatal development process. Choices A, B, and D are incorrect because the appearance of the umbilical cord as a primitive body stalk typically occurs around week 5-6, touch sensitivity extending to most of the body is more characteristic of the end of the second trimester, and the heartbeat is usually detectable through a stethoscope around the 18th to 20th week of pregnancy, not during the second month.
2. In healthy, physically fit women, regular moderate to vigorous exercise during pregnancy is related to __________.
- A. lower birth weight and higher risk of premature birth
- B. suppressed development of the immune system
- C. serious damage to the central nervous system
- D. improved fetal cardiovascular functioning
Correct answer: D
Rationale: In healthy, physically fit women, regular moderate to vigorous exercise during pregnancy is related to improved fetal cardiovascular functioning. Regular exercise has been shown to benefit both the mother and baby by promoting better cardiovascular health and overall well-being during pregnancy. Choices A, B, and C are incorrect as exercise during pregnancy, when done appropriately, does not lead to lower birth weight, higher risk of premature birth, suppressed immune system development, or serious damage to the central nervous system. Instead, it is known to have positive effects on fetal development and maternal health.
3. Dr. Torrez believes that how conflicts between biological drives and social expectations are resolved determines the person's ability to learn, to get along with others, and to cope with anxiety. Dr. Torrez accepts the __________.
- A. psychoanalytic perspective
- B. psychosocial theory
- C. cognitive-developmental theory
- D. social learning theory
Correct answer: A
Rationale: Dr. Torrez's belief about conflicts between biological drives and social expectations influencing a person's ability to learn, get along with others, and cope with anxiety aligns with the psychoanalytic perspective. This perspective, developed by Sigmund Freud, focuses on the unconscious mind, early childhood experiences, and the resolution of inner conflicts as important factors in shaping personality and behavior. The other choices are incorrect because psychosocial theory, cognitive-developmental theory, and social learning theory do not specifically focus on conflicts between biological drives and social expectations as central to understanding human behavior and development.
4. 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.
5. An inadequate diet during pregnancy can __________.
- A. lead to higher birth weight and greater brain weight
- B. reduce the risk of pregnancy-induced maternal diabetes
- C. distort the structure of the liver, kidney, and pancreas
- D. lead to fewer physical discomforts in the final weeks Answer: C Page Ref: 88 Skill Level: Understand Topic: Prenatal Environmental Influences Difficulty Level: Moderate
Correct answer: C
Rationale: An inadequate diet during pregnancy can lead to the distortion of the structure of the liver, kidney, and pancreas in the developing fetus. Proper nutrition during pregnancy is crucial for the healthy development of these organs and essential for the overall well-being of the baby. A balanced diet supports optimal growth and development, while inadequate nutrition can have detrimental effects on the baby's organs and long-term health.
