Human Growth and Development Final Exam

1. In the __________ period, teratogens rarely have any impact.

Correct answer: A

Rationale: In the germinal period of prenatal development, which lasts for about the first two weeks after fertilization, the developing organism is a zygote that has not yet implanted in the uterus. During this period, teratogens rarely have any impact because essential implantation and early cellular division processes are occurring. Teratogens are more likely to have significant effects during the later embryonic and fetal periods of development. Therefore, the correct answer is A. Choice B, embryonic period, is incorrect because teratogens have a higher likelihood of impacting development during this period. Choice C, fetal period, is also incorrect as teratogens can impact development during this stage as well. Choice D, prenatal, is a broad term encompassing the entire period of development from conception to birth and is not a specific developmental stage where teratogens have a minimal impact.

2. Which statement about prenatal rubella is true?

Correct answer: B

Rationale: The statement that the organ damage inflicted by prenatal rubella can lead to lifelong health problems is true. Rubella infection during pregnancy can cause serious harm to the developing fetus, including organ damage, deafness, heart defects, and intellectual disabilities. This highlights the importance of prevention and vaccination to protect both pregnant women and their unborn babies from the harmful effects of rubella.

3. Liz is 36 weeks pregnant. A rise in her baby's heart rate is probably followed within five seconds by __________.

Correct answer: A

Rationale: A rise in the baby's heart rate during pregnancy is usually followed within five seconds by a burst of motor activity. This indicates that the baby is responding to stimuli and is an important sign of healthy fetal development. A period of sleep, a rise in Liz's heart rate, or a drop in Liz's body temperature are not typically immediate responses to changes in the baby's heart rate. Sleep is less likely to be a direct response to changes in heart rate, Liz's heart rate is independent of the baby's heart rate changes, and a drop in Liz's body temperature is not a common immediate response to fetal heart rate changes.

4. An inadequate diet during pregnancy can __________.

Correct answer: C

Rationale: An inadequate diet during pregnancy can lead to the distortion of the structure of the liver, kidney, and pancreas in the developing fetus. Proper nutrition during pregnancy is crucial for the healthy development of these organs and essential for the overall well-being of the baby. A balanced diet supports optimal growth and development, while inadequate nutrition can have detrimental effects on the baby's organs and long-term health.

5. Which of the following is a situational barrier to seeking early prenatal care?

Correct answer: B

Rationale: Difficulty arranging transportation can be a situational barrier to seeking early prenatal care because it can prevent pregnant individuals from being able to physically get to their healthcare provider for appointments. This barrier may make it challenging for individuals to access the necessary prenatal care and support for a healthy pregnancy.
