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. Before the late 1800s, childbirth usually took place __________.
- A. at home and was a family-centered event
- B. at home, but away from other family members
- C. in a hospital with trained midwives
- D. in the home of a medical professional or in a hospital
Correct answer: A
Rationale: Before the late 1800s, childbirth usually took place at home and was a family-centered event. During this period, most women gave birth at home with the help of family members and possibly a midwife. Hospitals were not common settings for childbirth at that time. Choice B is incorrect because childbirth was not typically done away from family members. Choice C is incorrect because hospitals were not the common setting for childbirth before the late 1800s. Choice D is incorrect because giving birth in the home of a medical professional or a hospital was not the norm during that period.
3. What reflex protects an infant from strong stimulation?
- A. Moro
- B. eye-blink
- C. sucking
- D. palmar grasp
Correct answer: B
Rationale: The correct answer is B: eye-blink. The eye-blink reflex is the one that protects an infant from strong stimulation by causing them to quickly shut their eyes in response to sudden bright light or a loud noise. This reflex helps to safeguard the infant's sensitive eyes from potential harm. The Moro reflex (choice A) is the startle reflex, the sucking reflex (choice C) helps with feeding, and the palmar grasp reflex (choice D) is when the infant's fingers close around an object placed in their hand; none of these reflexes specifically protect the infant from strong stimulation.
4. By the end of Greta's first month of pregnancy, her embryo __________.
- A. can sense its world
- B. is about ¼ inch long
- C. can suck its thumb
- D. can curl its toes
Correct answer: B
Rationale: By the end of Greta's first month of pregnancy, her embryo is about ¼ inch long. During the first month of pregnancy, the embryo is in the very early stages of development, and its size is typically around ¼ inch as it continues to grow and develop in the uterus. Choices A, C, and D are incorrect because sensory abilities like sensing the world, sucking thumb, and curling toes develop later in the pregnancy as the embryo progresses through different stages of development.
5. 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.
