Human Growth and Development Exam 1

Correct Answer: C

Rationale: Anoxia during labor and delivery can cause cerebral palsy. Cerebral palsy is a group of disorders that affect a person's ability to move and maintain balance and posture. It is caused by damage to the developing brain, often due to a lack of oxygen during labor and delivery. Spina bifida (Choice A) is a neural tube defect that occurs during embryonic development and is not directly caused by anoxia during labor. Anencephaly (Choice B) is a severe neural tube defect where the baby is born without parts of the brain and skull, not typically caused by anoxia during labor. Muscular dystrophy (Choice D) is a genetic disorder characterized by progressive muscle weakness and is not directly related to anoxia during labor and delivery.

Correct Answer: B

Rationale: The correct answer is B: "eliminate undesirable behaviors and increase desirable responses." Applied behavior analysis aims to modify behavior by focusing on eliminating unwanted behaviors and reinforcing desirable ones. It does not primarily deal with changes in temperament (choice A), self-perception (choice C), or personality traits (choice D). The approach involves techniques such as reinforcement to target specific behaviors, rather than broader cognitive processes or personality characteristics.

Correct Answer: D

Rationale: The harm done by teratogens depends on the age at the time of exposure. This means that the effects may vary depending on the developmental stage of the fetus when exposed to the teratogen. Teratogens can have different impacts at different stages of pregnancy, leading to a range of potential outcomes in terms of physical and/or cognitive development. Choices A, B, and C are incorrect because the harm caused by teratogens is not straightforward, may not be apparent at birth, and can go beyond physical damage, affecting cognitive development as well.

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.

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.
