Ψ Note: These questions are part of a larger data base of questions on Chapter 4 & are selected to represent the type of question you should expect on unit exam one. You can, in fact, expect to see many of these very same questions on that exam. Exam questions, however, may deal with topics not covered in the self tests or in lectures but are
discussed in your textbook. You are responsible for the content of your text book plus the content of lectures, interactive activities, & material on the web site.
Use these sample questions to test yourself & to practice for the test. Click on your choice to see if you are right.
1. The Apgar scale is administered
2. The neural tube becomes the
3. The most critical factor in attaining the age of viability (22 weeks) is the development of the
4. A teratogen is
 a substance or a condition that can cause birth defects.
a cell with extra chromosomes.
waste products from the embryo.
damage sustained to the placenta.
5. To say that a teratogen has a “threshold effect” means that it is:
harmful only to low-birthweight infants.
virtually harmless until exposure reaches a certain level.
harmful to certain developing organs when those organs are developing most
rapidly.
harmful only if the pregnant woman’s weight does not increase by a certain
minimum amount during her pregnancy.
6. Pregnant women who are HIV- positive
should always have abortions.
can reduce the risk of infecting their fetuses by having monthly HIV tests.
can reduce the risk of infecting their fetuses by avoiding a Cesarean delivery.
can reduce the risk of infecting their fetuses by taking AZT.
7. The 3rd through the 8th week after conception is called the:
fetal period.
ovum period.
germinal period.
embryonic period.
8. Normally, during birth
the placenta is expelled first.
the head emerges first.
the labor process takes around ten hours.
the labor process takes longer for the second pregnancy.
9. The most common teratogen in developed nations is
10. Anoxia refers to
a lack of oxygen.
cerebral hemorrhaging.
signs of cerebral palsy.
toxins in the blood.
11. During the germinal period, the first task of the outer cells is to
implant in the uterus.
find a permanent location in the ovaries.
divide as fast as possible.
differentiate into different types of tissue.
12. The fetus begins to develop male sex organs if

14. Research in genetic vulnerability to teratogens has found that
female embryos are more vulnerable than males.
genetic vulnerability guarantees a birth defect of some sort.
fraternal twins are equally vulnerable.
the XY chromosome pattern is more susceptible to damage.
15. A total Apgar of 3 means a newborn
is in excellent condition.
has an LBW.
is in critical condition.
is irritable and may be coughing or crying.
16. Kangaroo care refers to:
the fragmented care that the children of single parents often receive.
a program of increased involvement by mothers of low birth-weight infants.
the rigid attachment formed between mothers & offspring in the animal world.
none of these apply!
17. Synaptogenesis refers to the process by which;
the fetal brain develops new neurons.
new connections between neurons develop.
the neural tube forms during the middle trimester.
the cortex folds into layers in order to fit into the skull.
18. The critical period for preventing physical defects appears to be the
fetal period
zygote period
entire pregnancy
embryonic period
19. Neurogenesis refers to the process by which;
the fetal brain develops new neurons.
new connections between neurons develop.
the neural tube forms during the middle trimester.
the cortex folds into layers in order to fit into the skull.
20. In order, the correct sequence of prenatal development is
