Human Growth and Development Final Exam Answers
1. 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.
2. Prenatally malnourished babies frequently __________.
- A. reject breast milk
- B. have enlarged hearts
- C. catch respiratory illnesses
- D. have a higher-than-average birth weight
Correct answer: C
Rationale: Prenatally malnourished babies frequently catch respiratory illnesses. Malnourished babies have weakened immune systems, making them more susceptible to illnesses such as respiratory infections. This is a common consequence that is observed in babies who did not receive adequate nutrition during the prenatal period. Choices A, B, and D are incorrect. While malnourished babies may have feeding challenges, rejecting breast milk is not a common consequence. Enlarged hearts are not typically associated with prenatal malnutrition, and having a higher-than-average birth weight is unlikely in malnourished babies.
3. Cindy tells her daughter, “I know you can do a good job on that homework†because she believes that if she encourages persistence, her daughter will start to view herself as hardworking and high-achieving. Cindy is applying the __________ approach.
- A. behavior modification
- B. psychosocial
- C. cognitive-developmental
- D. social-cognitive Answer: D Page Ref: 17 Skill Level: Apply Topic: Mid-Twentieth-Century Theories Difficulty Level: Difficult
Correct answer: D
Rationale: Cindy is applying the social-cognitive approach by encouraging her daughter to believe in her own abilities and persist in her efforts. This approach emphasizes the importance of social influences and cognitive processes in shaping behavior. By providing positive reinforcement and fostering a belief in her daughter's capabilities, Cindy is helping to shape her daughter's self-perception and motivation to achieve success.
4. During Irina's first week of pregnancy, __________.
- A. heart muscles begin to develop
- B. the zygote multiplies and forms a blastocyst
- C. a primitive brain and spinal cord appear
- D. the embryo can move
Correct answer: B
Rationale: During the first week of pregnancy, the zygote (fertilized egg) undergoes rapid cell divisions and forms a blastocyst. This is a crucial stage where the cells differentiate and specialize, setting the foundation for the development of the embryo. It is during this time that the zygote implants itself into the uterine wall, initiating the process of pregnancy. Choices A, C, and D are incorrect because during the first week of pregnancy, the focus is on the initial development and multiplication of the zygote, not on the development of heart muscles, a primitive brain and spinal cord, or the embryo's ability to move.
5. 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.
