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. When trying to soothe a crying baby, what technique do Western parents typically attempt first?
- A. Massaging the baby's body
- B. Offering a pacifier and a receiving blanket
- C. Playing recorded womb sounds or sounds of nature
- D. Lifting the baby to the shoulder and rocking or walking
Correct answer: D
Rationale: When Western parents aim to soothe a crying baby, the technique they usually try first is lifting the baby to the shoulder and rocking or walking. This method is effective because the motion and closeness provided by rocking or walking can help calm the baby and offer comfort. Choice A is incorrect as massaging the baby's body is not typically the first technique used. Choice B is incorrect as offering a pacifier and a receiving blanket may be tried after lifting the baby to the shoulder. Choice C is also incorrect as playing recorded sounds is usually not the initial technique attempted.
3. T. Berry Brazelton's Neonatal Behavioral Assessment Scale (NBAS) evaluates a newborn's __________.
- A. risk for developmental problems
- B. ability to comply with parental commands and responsiveness to touch
- C. reflexes, muscle tone, state changes, and responsiveness to stimulation
- D. heart rate, respiratory effort, reflex irritability, muscle tone, and color
Correct answer: C
Rationale: T. Berry Brazelton's Neonatal Behavioral Assessment Scale (NBAS) evaluates a newborn's reflexes, muscle tone, state changes, and responsiveness to stimulation. This assessment helps healthcare providers understand the newborn's behavioral responses and capabilities in various areas, providing valuable insights into their overall development and well-being. Choices A, B, and D are incorrect because the NBAS focuses on assessing the newborn's behavioral responses and capabilities, rather than their risk for developmental problems, compliance with commands, or physiological parameters like heart rate and respiratory effort.
4. When the blastocyst burrows deep into the uterine lining, __________.
- A. implantation occurs
- B. pregnancy does not occur
- C. it stops growing
- D. the cells of the zygote first duplicate
Correct answer: A
Rationale: When the blastocyst burrows deep into the uterine lining, this process is known as implantation. Implantation is a crucial step in the early stages of pregnancy where the blastocyst attaches to the uterine wall in order to receive nourishment and continue developing. Choice B is incorrect because implantation is a necessary step for pregnancy to occur. Choice C is incorrect as implantation marks the beginning of further growth and development. Choice D is incorrect as the duplication of cells occurs during earlier stages of development, not during implantation.
5. When classmates are asked to rate each other's likability, __________ children get many positive votes, whereas __________ children are seldom mentioned.
- A. popular; neglected
- B. neglected; rejected
- C. popular; rejected
- D. controversial; neglected
Correct answer: A
Rationale: The correct answer is A: 'popular; neglected.' Popular children are well-liked by their peers, hence they receive many positive votes. Neglected children, on the other hand, are often overlooked or ignored, resulting in them being seldom mentioned. Choice B is incorrect because neglected and rejected have different meanings. Choice C is incorrect as popular and rejected do not align with the likability context provided in the question. Choice D is incorrect as controversial does not directly relate to likability in the context of the question.
