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. What is the function of the corpus luteum?
- A. is where fertilization usually takes place
- B. secretes hormones that prepare the lining of the uterus to receive a fertilized ovum
- C. is one of two long, thin structures that lead to the hollow, softly lined uterus
- D. is one of two walnut-sized organs located deep inside a woman's abdomen
Correct answer: B
Rationale: The correct answer is B. The corpus luteum is a temporary endocrine structure in the ovary that forms after ovulation. It secretes hormones, particularly progesterone, which help prepare the uterine lining for possible implantation of a fertilized ovum. This process is crucial for maintaining a potential pregnancy. Choices A, C, and D are incorrect. Choice A is inaccurate as fertilization typically occurs in the fallopian tubes. Choice C describes the fallopian tubes, not the corpus luteum. Choice D refers to the ovaries, not specifically the corpus luteum.
3. __________ theory was the first to stress the influence of the early parent‒child relationship on development.
- A. Darwin’s
- B. Freud’s
- C. Erikson’s
- D. Watson’s Answer: B Page Ref: 15 Skill Level: Remember Topic: Mid-Twentieth-Century Theories Difficulty Level: Easy
Correct answer: B
Rationale: Freud's theory was the first to stress the influence of the early parent‒child relationship on development. Sigmund Freud's psychoanalytic theory emphasized the importance of the child's interactions with caregivers, particularly during the early stages of development, in shaping personality and behavior.
4. __________ emerges early prenatally and is well-developed at birth.
- A. Visual acuity
- B. Color vision
- C. Depth perception
- D. Sensitivity to touch
Correct answer: D
Rationale: Sensitivity to touch emerges early prenatally and is well-developed at birth. Newborn babies have a well-developed sense of touch, which is crucial for bonding with their caregivers and exploring their environment. This sensitivity to touch helps babies respond to comforting sensations such as gentle strokes and cuddles. Visual acuity, color vision, and depth perception are sensory capabilities that develop and mature after birth, not prenatally. While important for interacting with the environment, they are not as well-developed at birth as sensitivity to touch.
5. During the third stage of labor, __________.
- A. the cervix thins to nothing
- B. uterine contractions begin
- C. the placenta is delivered
- D. the baby is born
Correct answer: C
Rationale: During the third stage of labor, the correct answer is C, the placenta is delivered. This stage occurs after the baby is born and involves the expulsion of the placenta from the uterus. Choice A is incorrect because the thinning of the cervix to nothing typically occurs during the first stage of labor. Choice B is incorrect as uterine contractions usually begin during the first stage of labor to help with the dilation of the cervix. Choice D is incorrect because the baby is typically born in the second stage of labor, not the third.
