ATI RN

Human Growth and Development Final Exam

1. In mammals, including humans, the sense of smell __________.

A. does not become adultlike for several years
B. helps mothers and babies identify each other
C. is the least developed sense at birth
D. takes about four months to become adultlike

Correct answer: B

Rationale: The sense of smell in mammals, including humans, plays a crucial role in helping mothers and babies identify each other. This is important for initiating bonding and caregiving behaviors. Choice A is incorrect because the sense of smell is functional at birth and not entirely underdeveloped for several years. Choice C is incorrect as the sense of smell is actually well-developed at birth. Choice D is incorrect because the sense of smell is functional from birth and does not take several months to become adultlike.

2. Dr. Bigelow is interested in studying musical prodigies. Which method is best suited for this type of research?

A. naturalistic observation
B. clinical interview
C. case study
D. structured interview

Correct answer: C

Rationale: A case study would be the best method for Dr. Bigelow to study musical prodigies. In a case study, the researcher can closely examine and analyze the unique characteristics, abilities, and behaviors of individual subjects. This method allows for in-depth exploration of a specific phenomenon, making it ideal for investigating exceptional cases such as musical prodigies. Naturalistic observation involves observing subjects in their natural environment without interference, which may not provide the detailed insights needed for studying musical prodigies. Clinical interviews focus on gathering information through structured questioning, not ideal for studying unique talents. Structured interviews involve asking a set of predetermined questions, which may not allow for the depth of exploration required for studying musical prodigies.

3. At Kohlberg's Stage __________, individuals can imagine alternatives to their own social order, and they emphasize fair procedures for interpreting and changing the law.

A. 3, the 'good boy/good girl' orientation
B. 4, the social-order-maintaining orientation
C. 5, the social contract orientation
D. 6, the universal ethical principle orientation

Correct answer: C

Rationale: The correct answer is C: '5, the social contract orientation.' At Kohlberg's Stage 5, individuals begin to question their own social order and focus on principles of justice and fairness. This stage emphasizes the importance of social contracts and agreements based on mutual benefit. Choice A is incorrect as the 'good boy/good girl' orientation is characteristic of Stage 3. Choice B, the social-order-maintaining orientation, does not align with the description provided in the question. Choice D, the universal ethical principle orientation, is associated with Stage 6, where individuals act based on self-chosen ethical principles.

4. A combined Apgar score of __________ indicates that the infant is in good physical condition.

A. less than 3
B. 3 or 4
C. 5 or 6
D. 7 or better

Correct answer: D

Rationale: A combined Apgar score of 7 or better indicates that the infant is in good physical condition. The Apgar score is a quick assessment of a newborn's overall health shortly after birth. It evaluates the baby's heart rate, respiratory effort, muscle tone, reflexes, and color. A score of 7 or higher indicates that the baby is adjusting well to life outside the womb. Choices A, B, and C are incorrect as they represent scores that indicate the infant may need medical attention or assistance as they are below the threshold of 7 which signifies good physical condition.

5. The term teratogen refers to __________.

A. any environmental agent that causes damage during the prenatal period
B. a limited time span during which a part of the body is biologically prepared to develop rapidly
C. a rapid period of prenatal neurological development
D. a synthetic hormone used to prevent miscarriage

Correct answer: A

Rationale: The correct answer is A: 'any environmental agent that causes damage during the prenatal period.' A teratogen is any substance or factor that can cause harm to the developing fetus during pregnancy. Choice B is incorrect because it describes a critical period, not a teratogen. Choice C is incorrect as it refers to a specific period of development, not a teratogen. Choice D is incorrect because it describes a synthetic hormone, not a teratogen.
