Human Growth and Development Final Exam Answers
1. What is the function of the amniotic fluid?
- A. Delivers food and oxygen to the developing organism
- B. Helps keep the temperature of the prenatal world constant
- C. Delivers nutrients and removes waste products
- D. Produces blood cells until the organs are mature enough to take over this function
Correct answer: B
Rationale: The correct answer is B: 'Helps keep the temperature of the prenatal world constant.' Amniotic fluid helps maintain a stable and warm environment for the developing organism, assisting in regulating the temperature. This fluid also acts as a cushion, protecting the fetus from physical harm. Choices A, C, and D are incorrect because while amniotic fluid provides protection and support to the developing organism, it does not directly deliver food, oxygen, nutrients, or remove waste products, nor does it produce blood cells as the organs eventually take over this function.
2. __________ doubles the risk of SIDS.
- A. Failure to tightly swaddle an infant during sleep
- B. Use of a pacifier or a security blanket
- C. Placing an infant to sleep on his back
- D. Cigarette smoking by a caregiver Answer: D Page Ref: 106 Box: BIOLOGY AND ENVIRONMENT: The Mysterious Tragedy of Sudden Infant Death Syndrome Skill Level: Understand Topic: The Newborn Baby’s Capacities Difficulty Level: Moderate
Correct answer: D
Rationale: Cigarette smoking by a caregiver doubles the risk of SIDS. Secondhand smoke exposure can increase the likelihood of SIDS due to the toxins and chemicals present in cigarette smoke. It is important to have a smoke-free environment for infants to reduce the risk of SIDS.
3. Which of the following is the best available predictor of infant survival and healthy development?
- A. Birth length
- B. Combined Apgar score
- C. Delivery date
- D. Birth weight
Correct answer: D
Rationale: The correct answer is 'Birth weight.' Birth weight is a crucial indicator of an infant's chances of survival and well-being. Low birth weight is associated with various health risks and developmental challenges. Birth length (choice A) is not as significant in predicting infant outcomes as birth weight. The Combined Apgar score (choice B) is a measure of the newborn's health status at birth, not a predictor of long-term survival and development. Delivery date (choice C) is important for determining gestational age but is not as directly related to infant survival and healthy development as birth weight.
4. Which mother is most likely to have had inadequate prenatal care?
- A. Lupe, age 25
- B. Marissa, age 32
- C. Rotunda, age 16
- D. Janette, age 40
Correct answer: C
Rationale: Rotunda, age 16, is the most likely to have had inadequate prenatal care due to her young age and possibly limited access to healthcare resources and support. Adolescents are at higher risk for inadequate prenatal care compared to older mothers due to various factors such as lack of awareness, financial constraints, and inconsistent health behaviors. Young mothers may face challenges in seeking proper prenatal care due to reasons like lack of knowledge, fear of judgment, or limited financial means. Older mothers like Lupe, Marissa, and Janette are less likely to have inadequate prenatal care compared to a younger mother like Rotunda, as they may have more access to resources, experience, and support systems.
5. The __________ reflex helps a newborn find the nipple.
- A. rooting
- B. Moro
- C. Babinski
- D. tonic neck Answer: A Page Ref: 101 Skill Level: Understand Topic: The Newborn Baby’s Capacities Difficulty Level: Moderate
Correct answer: A
Rationale: The rooting reflex is the correct answer. This reflex helps a newborn baby find the nipple by turning their head and opening their mouth when their cheek is stroked or touched. This is crucial for the baby to locate and latch onto the mother's breast for feeding. The rooting reflex typically disappears around 4 months of age.
