Human Growth and Development Clep Practice Exam

1. How does physical activity impact mental health?

A. Reduces anxiety and depression
B. Improves mood, but decreases alertness
C. Decreases mood, alertness, and energy
D. Decreases neural activity in the cerebral cortex

Correct answer: A

Rationale: Physical activity is known to have a positive impact on mental health by reducing symptoms of anxiety and depression. Choice B is incorrect because physical activity generally improves both mood and alertness. Choice C is incorrect as physical activity tends to increase mood, alertness, and energy levels. Choice D is incorrect as physical activity actually increases neural activity in the cerebral cortex, which is associated with improved cognitive function and mental well-being.

2. Natural childbirth experts Grantly Dick-Read and Fernand Lamaze recognized that cultural attitudes about childbirth had __________.

A. taught women to fear the birth experience
B. helped women develop breathing techniques to lessen the pain of labor
C. taught women that medical intervention was unnecessary in childbirth
D. helped women focus on child rearing rather than childbirth

Correct answer: A

Rationale: Natural childbirth experts Grantly Dick-Read and Fernand Lamaze recognized that cultural attitudes about childbirth had taught women to fear the birth experience. They believed that this fear contributed to increased pain during labor and advocated for methods to reduce fear and promote relaxation during childbirth. Choice B is incorrect as the focus is on fear, not on techniques to lessen pain. Choice C is incorrect as the experts did not advocate against medical intervention but rather against unnecessary fear. Choice D is incorrect as the experts aimed to change attitudes towards childbirth, not redirect focus to child rearing.

3. Which statement about prenatal marijuana exposure is true?

A. It is linked to impulsivity and overactivity.
B. Lasting consequences are well-established.
C. Studies show no negative effects of exposure.
D. It is linked to an array of physical malformations.

Correct answer: A

Rationale: The correct answer is A: 'It is linked to impulsivity and overactivity.' Prenatal marijuana exposure has been associated with impulsivity and overactivity in children based on research findings. However, lasting consequences of prenatal marijuana exposure are not as well-established compared to other teratogens. Choice B is incorrect because lasting consequences are not firmly established. Choice C is incorrect because studies have shown negative effects of prenatal marijuana exposure. Choice D is incorrect as prenatal marijuana exposure is not primarily linked to physical malformations.

4. 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.

5. In the eighth month of pregnancy, what typically happens?

A. fetal growth doubles
B. neuron production increases
C. the eyes, ears, nose, jaw, and neck form
D. lanugo typically is shed

Correct answer: D

Rationale: In the eighth month of pregnancy, lanugo typically is shed. Lanugo is the fine, downy hair that covers a fetus's body to help regulate body temperature while in the womb. By the eighth month, many fetuses shed this hair as they prepare for birth. Choices A, B, and C are incorrect because fetal growth doubling, neuron production increasing, and the formation of eyes, ears, nose, jaw, and neck occur in earlier stages of pregnancy, not specifically in the eighth month.
