Human Growth and Development Final Exam Answers

1. Although great diversity characterizes the interests and concerns of investigators who study development, they share a single goal: to identify __________.

A. genetic factors that contribute to longevity
B. environmental factors that contribute to disease and illness
C. those factors that lead to abnormal development in children and adolescents
D. those factors that influence consistencies and transformations in people from conception to death

Correct answer: D

Rationale: The correct answer is D because investigators who study development aim to identify the factors that influence consistencies and transformations in people from conception to death. This goal encompasses various domains such as physical, cognitive, emotional, and social development, highlighting the comprehensive nature of developmental research. Choices A, B, and C are incorrect as they do not align with the overarching goal of developmental researchers, which is to understand the factors influencing individuals throughout their lifespan, rather than focusing solely on genetic factors, environmental factors related to disease, or abnormal development in specific age groups.

2. Which Apgar criterion can be more difficult to apply to newborns of all races?

A. pink color
B. reflex irritability
C. limp muscle tone
D. strong breathing

Correct answer: D

Rationale: Among the Apgar criteria, the pink color (choice A), reflex irritability (choice B), and limp muscle tone (choice C) are relatively easy to assess in newborns of all races. However, the criterion that can be more difficult to apply to newborns of all races is strong breathing (choice D). This is because evaluating the strength of a newborn's breathing can be more subjective and require careful observation. Unlike the other criteria that have more visible and objective indicators, assessing the strength of breathing might vary based on the observer's interpretation, making it more challenging to apply universally.

3. What is the most common approach to controlling pain during labor?

A. an anesthetic
B. a spinal block
C. fetal monitoring
D. epidural analgesia

Correct answer: D

Rationale: Epidural analgesia is the most common approach to controlling pain during labor. It involves the administration of pain medication through a catheter placed in the epidural space of the spine, providing pain relief while allowing the mother to remain alert and participate in the birthing process. It is preferred by many women due to its effectiveness in reducing labor pain. Choices A, B, and C are incorrect as they do not directly address pain management during labor. While an anesthetic and a spinal block are forms of pain relief, epidural analgesia is specifically the most common method used for pain control during labor.

4. Which statement about the human immunodeficiency virus (HIV) is true?

A. About 30 percent of all new HIV infections affect women.
B. In South Africa, 30 percent of all pregnant women are HIV-positive.
C. About 30 percent of new HIV infections occur in developing countries.
D. Untreated HIV-infected mothers pass the virus to the fetus 30 percent of the time.

Correct answer: B

Rationale: The correct answer is B: 'In South Africa, 30 percent of all pregnant women are HIV-positive.' This statement is true as South Africa has a high prevalence of HIV among pregnant women, emphasizing the need for interventions to prevent mother-to-child transmission. Choices A, C, and D are incorrect. Choice A is inaccurate as women account for more than 50% of new HIV infections globally. Choice C is misleading as the majority of new HIV infections actually occur in sub-Saharan Africa, not just developing countries. Choice D is also incorrect as without treatment, the risk of mother-to-child transmission is higher than 30%.

5. A 20-week-old fetus can __________.

A. be stimulated as well as irritated by sounds
B. survive, if born early
C. breathe without oxygen assistance, if born early
D. control its own body temperature Answer: A Page Ref: 80 Skill Level: Understand Topic: Prenatal Development Difficulty Level: Moderate

Correct answer: A

Rationale: A 20-week-old fetus is able to be stimulated as well as irritated by sounds because by this stage of prenatal development, the fetus's auditory system is already well-developed. It can respond to external sounds and may even startle or move in reaction to loud noises.
