Low-level radiation, resulting from industrial leakage or medical X-rays, __________.
- A. is harmful only when combined with other teratogens
- B. can increase the risk of childhood cancer
- C. rarely causes lasting damage
- D. is safe during the last trimester
Correct Answer: B
Rationale: Low-level radiation, whether from industrial leakage or medical X-rays, can increase the risk of childhood cancer by potentially damaging the developing fetus's cells. Even though the risk is relatively low, it is still a significant concern that should be acknowledged and monitored closely, especially during prenatal development. Choice A is incorrect as low-level radiation can still be harmful on its own without the need to be combined with other teratogens. Choice C is incorrect because low-level radiation exposure can indeed cause lasting damage, especially in the context of childhood cancer risk. Choice D is incorrect because low-level radiation exposure, even during the last trimester, can pose risks to the developing fetus and is not considered entirely safe.

Like Piaget's theory, the information-processing approach __________.
- A. divides development into stages
- B. views development as discontinuous
- C. regards people as actively making sense of their own thinking
- D. has much to say about nonlinear cognition, such as imagination and creativity
Correct Answer: C
Rationale: The correct answer is C: 'regards people as actively making sense of their own thinking.' The information-processing approach, similar to Piaget's theory, focuses on how individuals actively process information, encode it, store it, and retrieve it to understand the world around them. Choices A and B are incorrect because the information-processing approach does not necessarily divide development into stages or view development as discontinuous. Choice D is incorrect because the information-processing approach is more concerned with cognitive processes like encoding, storage, and retrieval, rather than nonlinear cognition such as imagination and creativity.
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.
Tiffany is a small-for-date baby. This means she __________.
- A. was born several weeks or more before her due date
- B. was born below her expected weight considering the length of the pregnancy
- C. will probably have much less serious problems than a preterm infant
- D. may have difficulties in infancy but will outgrow them by the preschool years
Correct Answer: B
Rationale: A small-for-date baby, also known as a small-for-gestational-age (SGA) baby, is a baby who is born below their expected weight considering the length of the pregnancy. This can be due to various factors including issues with growth restriction in the womb. Being small-for-date is different from being preterm (born prematurely) and does not necessarily mean that the baby was born early. Choice A is incorrect because being small-for-date does not specifically indicate being born several weeks or more before the due date. Choice C is incorrect because being small-for-date does not guarantee fewer problems than a preterm infant, as each baby's health outcomes can vary. Choice D is incorrect because while small-for-date babies may have initial difficulties, it does not guarantee that these issues will be outgrown by the preschool years.
According to Piaget, in which stage of cognitive development is four-year-old R'Monte who engages in make-believe play by stirring beads in a bowl and saying, "Soup is ready!"?
- A. sensorimotor
- B. preoperational
- C. concrete operational
- D. sociocultural
Correct Answer: B
Rationale: According to Piaget's theory of cognitive development, four-year-old Rƒ¢¢â€š¬¢â€ž¢Monte's engagement in make-believe play, such as pretending to stir beads in a bowl and creating imaginary soup, indicates that he is in the preoperational stage of cognitive development. This stage is characterized by symbolic thinking, pretend play, language development, and egocentrism. Choice A, sensorimotor, is incorrect as this stage occurs in infancy and focuses on sensory experiences and object permanence. Choice C, concrete operational, is incorrect as this stage occurs around ages 7-11 and involves logical reasoning about concrete events. Choice D, sociocultural, is incorrect as it does not correspond to Piaget's stages of cognitive development.
One criticism of Freud's psychosexual theory was that it __________.
- A. did not apply to other cultures
- B. underemphasized the influence of sexual feelings
- C. compared human development to the evolution of the human species
- D. offered too narrow a view of important environmental influences
Correct Answer: A
Rationale: One criticism of Freud's psychosexual theory was that it did not apply to other cultures. Freud developed his theory based on observations and cases from his clinical practice in a specific cultural context, mainly Western society. This limited cultural scope raised concerns about the generalizability and applicability of his theories to diverse cultural settings. Choice B is incorrect because Freud's theory actually emphasized the significant influence of sexual feelings on human development. Choice C is incorrect because Freud's theory focused on stages of psychosexual development rather than comparing human development to the evolution of the human species. Choice D is incorrect because Freud's psychosexual theory considered environmental influences, although it primarily centered on internal drives and conflicts.
