1. During pregnancy, the placenta __________.
- A. forms in the second trimester of pregnancy
- B. encloses the developing organism in amniotic fluid
- C. contains one large vein that delivers nutrients to the embryo
- D. delivers food and oxygen to the developing organism
Correct answer: D
Rationale: The placenta delivers food and oxygen to the developing organism during pregnancy. It is a temporary organ that forms in the first trimester of pregnancy. Choice A is incorrect as the placenta forms in the first trimester, not the second trimester. Choice B is incorrect as the amniotic sac, not the placenta, encloses the developing organism in amniotic fluid. Choice C is incorrect as the placenta contains blood vessels (arteries and veins) that deliver nutrients to the embryo, not just one large vein.
2. 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.
3. When children are research participants, __________.
- A. Investigators need to seek the opinion of others if in doubt about the harmful effects of research.
- B. They have the right to concealment of their identity on information collected in the course of research.
- C. There is a need to inform them or their parents of the results of the research.
- D. Informed consent of their parents as well as others who act on their behalf should be obtained.
Correct answer: D
Rationale: When children are research participants, it is essential to obtain informed consent from their parents or others who act on their behalf. This is to ensure that the child's rights and well-being are protected during the research process. Informed consent is a fundamental ethical principle in research involving children, as they may not have the capacity to fully understand the implications of their participation. Choice A is incorrect because seeking the opinion of others when in doubt about harmful effects is not a substitute for informed consent. Choice B is incorrect because children do not have an absolute right to conceal their identity in research, especially when it comes to ensuring their safety and well-being. Choice C is incorrect as it is important to inform children or their parents about the results of the research to maintain transparency and respect for their participation.
4. 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.
5. 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.
