1. Which of the following best describes the blastogenic stage of gestation?
A) The period from week 2 to week 8 when organ systems develop
B) The first 14 days after conception during which rapid cell division occurs
C) The period from week 9 to week 40 characterized by continual growth
D) The final weeks of pregnancy when the fetus gains the most weight
Correct Answer: The first 14 days after conception during which rapid cell division occurs
Rationale: The blastogenic stage is the first stage of gestation, occurring from day 1 to day 14 after
conception, and is characterized by rapid cell division. The embryonic stage occurs from week 2 to week
8, and the fetal stage occurs from week 9 to week 40.
2. Development occurs from about week two through which week, a period known as the embryonic
stage?
A) Week 4
B) Week 6
C) Week 8
D) Week 10
Correct Answer: Week 8
Rationale: The embryonic stage of gestation occurs from approximately week 2 through week 8. During
this critical period, the organ systems develop, and by week 8 the embryo is known as a fetus.
3. The fetal stage of gestation occurs from week nine to the end of pregnancy and is characterized by:
A) Rapid cell division and implantation
,B) Organ system development
C) Continual growth and development
D) Preparation for labor and delivery
Correct Answer: Continual growth and development
Rationale: The fetal stage occurs from week 9 to week 40 and is a period of continual growth and
development. This stage follows the embryonic stage and is characterized by significant increases in size
and weight.
4. All pregnancies are divided into three equal time periods known as:
A) Stages
B) Phases
C) Trimesters
D) Cycles
Correct Answer: Trimesters
Rationale: All pregnancies are divided into three equal time periods, known as trimesters, each lasting
approximately 13-14 weeks. A baby born after the thirty-seventh week of pregnancy is considered full
term.
5. A baby born after the thirty-seventh week of pregnancy is considered:
A) Premature
B) Full term
C) Late term
D) Post-term
Correct Answer: Full term
, Rationale: A baby born after the thirty-seventh week of pregnancy is considered full term. Births before
37 weeks are considered preterm, while those after 42 weeks are post-term.
6. What is the term for the consistent eating of non-nutritive substances for at least one month?
A) Anorexia
B) Bulimia
C) Pica
D) Binge eating
Correct Answer: Pica
Rationale: Pica is defined as an abnormal craving for both food and nonfood items, characterized by the
consistent eating of non-nutritive substances for at least a month. This condition can lead to nutrient
deficiencies and other health complications.
7. A pregnant patient is diagnosed with pica and is consuming clay. Which nutrient deficiency is most
commonly associated with this condition?
A) Calcium
B) Iron
C) Vitamin C
D) Vitamin D
Correct Answer: Iron
Rationale: Pica is often associated with iron deficiency anemia. The consumption of non-nutritive
substances such as clay, dirt, or ice may be a sign of iron deficiency, and treatment of the underlying
deficiency often resolves the pica behavior.
8. Which of the following is NOT considered a teratogen?
A) Alcohol
B) Tobacco
