1. During which period does the germinal period occur?

• A. Occurs during the second trimester of pregnancy
• B. Lasts about six weeks
• C. Lasts about two weeks
• D. Is the final period of a 38-week pregnancy

Correct answer: C

Rationale: The germinal period lasts about two weeks and occurs during the first two weeks of pregnancy. This is the time when the fertilized egg implants into the uterus and begins to divide rapidly. It is followed by the embryonic period, which lasts from about week 3 to week 8 of pregnancy. Choice A is incorrect because the germinal period happens in the early stages of pregnancy, not the second trimester. Choice B is incorrect because the germinal period typically lasts about two weeks, not six. Choice D is incorrect because the germinal period is an early stage of pregnancy and not the final period of a 38-week pregnancy.

2. In a correlational design, researchers __________.

• A. gather information on individuals without altering their experiences
• B. divide events and behaviors of interest into two types: dependent and independent variables
• C. use an evenhanded procedure to assign people to two or more treatment conditions
• D. directly control or manipulate changes in the independent variable

Correct answer: A

Rationale: In a correlational design, researchers gather information on individuals without altering their experiences. Correlational studies examine the relationship between two or more variables without any manipulation or control by the researchers. The researchers simply observe and measure the variables of interest without intervening in any way. Choices B, C, and D are incorrect because they describe aspects related to experimental designs rather than correlational designs. In an experimental design, researchers manipulate variables, assign participants to different treatment conditions, and control changes in the independent variable, which is not the case in correlational studies.

3. In developing countries, the most readily available intervention for promoting the recovery of preterm babies is _________.

• A. hospitalization
• B. care in an isolette
• C. lying on a waterbed
• D. skin-to-skin 'kangaroo care'

Correct answer: D

Rationale: In developing countries, the most readily available intervention for promoting the recovery of preterm babies is skin-to-skin 'kangaroo care.' This involves direct skin-to-skin contact between the baby and a caregiver, typically the mother, which helps regulate the baby's body temperature, improve bonding, and support overall development. Kangaroo care can be easily implemented even in resource-limited settings and has been shown to have positive effects on preterm infants' health outcomes. Choices A, B, and C are incorrect because hospitalization, care in an isolette, and lying on a waterbed are not specifically tailored interventions that address the unique needs of preterm babies in developing countries like kangaroo care does.

4. During prenatal development, the ectoderm folds over to form the __________, or primitive spinal cord.

• A. mesoderm; neuron tract
• B. neural tube
• C. endoderm; neural tube
• D. neuron tract

Correct answer: B

Rationale: The correct answer is B. During prenatal development, the ectoderm folds over to form the neural tube, which eventually develops into the brain and spinal cord. The neural tube is the precursor to the central nervous system, including the primitive spinal cord. Choices A, C, and D are incorrect because the mesoderm does not form the neural tube, the endoderm is not involved in the formation of the central nervous system, and neuron tract is not the structure that forms the primitive spinal cord.

5. Chinara is Rh-negative and Savon, her first child, is Rh-positive. Chinara's doctor will probably __________.

• A. give Savon a vaccine to prevent heart damage and intellectual disabilities
• B. advise Chinara not to have another child due to Rh incompatibility
• C. give Chinara a vaccine to prevent the buildup of antibodies to the foreign Rh protein
• D. do nothing because firstborn children are not affected by Rh incompatibility

Correct answer: C

Rationale: Chinara is Rh-negative and Savon, her first child, is Rh-positive. This presents a risk of Rh incompatibility in future pregnancies. To prevent the buildup of antibodies to the foreign Rh protein and protect future pregnancies, Chinara's doctor will likely give her a vaccine known as RhoGAM to prevent her immune system from reacting to Rh-positive blood cells. This vaccine helps to minimize the risks of complications in subsequent pregnancies. Choice A is incorrect because the vaccine is given to the mother, not the child. Choice B is incorrect as advising against having more children is not a typical response when preventive measures are available. Choice D is incorrect because all subsequent pregnancies are at risk of Rh incompatibility, not just the firstborn child.
