1. 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.

2. If pregnancy does not occur, the corpus luteum shrinks, and the __________.

• A. cells begin to duplicate
• B. one-celled zygote multiplies and forms a blastocyst
• C. germinal period lasts only about two weeks
• D. lining of the uterus is discarded

Correct answer: D

Rationale: If pregnancy does not occur, the corpus luteum will shrink. As a result, the lining of the uterus is discarded through the process of menstruation. This shedding of the uterine lining is what causes menstrual bleeding. Choices A, B, and C are incorrect because they do not describe the physiological response of the body when pregnancy does not occur. The corpus luteum shrinking and the subsequent shedding of the uterine lining are part of the menstrual cycle, not processes related to cell duplication, zygote multiplication, or the duration of the germinal period.

3. One criticism of the information-processing approach is that it __________.

• A. underestimates the individual's contribution to his or her own development
• B. ignores transformation in adulthood, concluding that no major cognitive changes occur after adolescence
• C. underestimates the competencies of infants and preschoolers, focusing on older children and adolescents
• D. is better at analyzing thinking into its components than at putting them back together into a comprehensive theory

Correct answer: B

Rationale: The criticism that the information-processing approach ignores transformation in adulthood, concluding that no major cognitive changes occur after adolescence, suggests a limitation of the theory in not fully acknowledging that cognitive development continues throughout the lifespan. This criticism highlights a potential drawback of the approach in terms of its understanding of cognitive changes beyond adolescence. Choice A is incorrect because the criticism is not about underestimating the individual's contribution. Choice C is also incorrect as the criticism is not related to age-specific competencies. Choice D is incorrect as it focuses on a different aspect of the information-processing approach.

4. When Baby Ian is held horizontally on his back, he sometimes makes an “embracing” motion by arching his back, extending his legs, throwing his arms outward, and then bringing his arms in toward his body. Ian is demonstrating the __________.

• A. palmar grasp
• B. Moro reflex
• C. tonic neck reflex
• D. Babinski reflex

Correct answer: B

Rationale: Baby Ian is demonstrating the Moro reflex. The Moro reflex is a normal newborn reflex that occurs when a baby feels like they are falling or losing support. It is characterized by arching the back, extending the legs, throwing the arms outward, and then bringing the arms in toward the body. This reflex is a primitive survival instinct that typically disappears around 6 months of age. Choice A, palmar grasp, involves the baby's fingers closing around an object when it touches their palm. Choice C, tonic neck reflex, involves the baby assuming a fencing position when their head is turned to one side. Choice D, Babinski reflex, is characterized by the fanning out and curling of the baby's toes when the sole of the foot is stroked.

5. This means that Andrew __________.

• A. is in good physical condition
• B. needs assistance in establishing breathing and other vital signs
• C. is in serious danger and should receive emergency medical attention
• D. was in danger at birth, but quickly recovered and is now in good physical condition Answer: B Page Ref: 95 Skill Level: Apply newborn baby’s appearance. Topic: Childbirth Difficulty Level: Difficult

Correct answer: B

Rationale: The statement "Andrew needs assistance in establishing breathing and other vital signs" refers to the initial steps taken to ensure a newborn's well-being after birth. This is a common practice to ensure that the newborn is transitioning smoothly into the outside world and is not indicative of a serious danger that requires emergency medical attention.
