1. In the United States, the second leading cause of neonatal mortality is __________, which is largely preventable.

• A. malnutrition
• B. physical abnormality
• C. low birth weight
• D. sudden infant death syndrome

Correct answer: C

Rationale: The second leading cause of neonatal mortality in the United States is low birth weight, which is largely preventable through proper prenatal care, nutrition, and health interventions. Low birth weight infants are at higher risk for various health complications and mortality, making it an important issue to address in maternal and child health programs. Malnutrition (choice A) can contribute to low birth weight but is not the direct cause of neonatal mortality. Physical abnormality (choice B) can be a factor in some cases but is not the second leading cause overall. Sudden infant death syndrome (choice D) refers to unexplained deaths of seemingly healthy babies and is not related to low birth weight as a leading cause of neonatal mortality.

2. The most rapid prenatal changes take place in the period of the __________.

• A. zygote
• B. blastocyst
• C. embryo
• D. fetus

Correct answer: C

Rationale: The correct answer is C: embryo. The most rapid prenatal changes occur during the embryo stage, which spans from approximately 2 to 8 weeks after conception. This period is crucial as major organs and systems of the body develop rapidly, laying the foundation for future growth and development. The zygote stage is the initial single-celled entity formed by the union of sperm and egg, while the blastocyst stage involves the cluster of cells resulting from the zygote dividing and growing. The fetus stage follows the embryo stage and focuses on refining and growing existing structures rather than rapid development. Therefore, the embryo stage is where the most significant and rapid changes take place in prenatal development.

3. The force of blood flowing through the __________ keeps it firm.

• A. amnion
• B. umbilical cord
• C. yolk sac
• D. embryonic disk

Correct answer: B

Rationale: The force of blood flowing through the umbilical cord keeps it firm. The umbilical cord is the connection between the placenta and the fetus, providing essential nutrients and oxygen to the developing baby. Blood flow through the umbilical cord helps maintain its structure and function throughout the prenatal period. Choices A, C, and D are incorrect as they do not play a role in providing nutrients and oxygen to the developing baby or in maintaining its firmness.

4. Newborn infants who are brain damaged or who have experienced birth trauma often __________.

• A. display disturbed REM-NREM sleep cycles
• B. cry less than those with no brain functioning problems
• C. spend about 20 percent of their total sleep time in REM sleep
• D. have very low or inaudible cries

Correct answer: A

Rationale: Newborn infants who are brain damaged or who have experienced birth trauma often display disturbed REM-NREM sleep cycles. This disruption in the sleep cycle can be a sign of neurological issues and can impact the newborn's overall health and development. Choice B is incorrect because infants with brain damage or birth trauma may actually cry more due to their discomfort or neurological issues. Choice C is incorrect because spending about 20 percent of total sleep time in REM sleep is not necessarily specific to brain-damaged or birth-traumatized infants. Choice D is incorrect because having very low or inaudible cries is not a common characteristic associated with brain damage or birth trauma in infants.

5. What is the best-known effect of smoking during the prenatal period?

• A. Colic
• B. Respiratory distress at birth
• C. Low birth weight
• D. Delayed language development

Correct answer: C

Rationale: The best-known effect of smoking during the prenatal period is low birth weight. Smoking during pregnancy is a known teratogen that can lead to negative outcomes for the developing fetus, such as growth restrictions resulting in low birth weight. This condition can have significant long-term consequences on the child's health and development. Choices A, B, and D are incorrect as they are not the primary effect associated with smoking during the prenatal period. Colic is typically associated with digestive issues, respiratory distress at birth can be caused by various factors other than smoking, and delayed language development is not directly linked to smoking during pregnancy.
