OB Final Exam Questions with
Accurate Answers
1. A 22-year-old woman pregnant with a single fetus has a preconception body
mass index (BMI) of 24. When she was seen in the clinic at 14 weeks of gestation,
she had gained 1.8 kg (4 lb) since conception. How would the nurse interpret this?
a. This weight gain indicates possible gestational hypertension.
b. This weight gain indicates that the woman's infant is at risk for intrauterine
growth restriction (IUGR).
c. This weight gain cannot be evaluated until the woman has been observed for
several more weeks.
d. The woman's weight gain is appropriate for this stage of pregnancy. correct

C. This weight gain cannot be evaluated until the woman has been observed for
several more weeks.
D. The woman's weight gain is appropriate for this stage of pregnancy. correct
answer ANS: D
The statement "The woman's weight gain is appropriate for this stage of
pregnancy" is accurate. This woman's BMI is within the normal range. During the
,first trimester, the average total weight gain is only 1 to 2 kg. Although weight
gain does indicate possible gestational hypertension, it does not apply to this
patient. The desirable weight gain during pregnancy varies among women. The
primary factor to consider in making a weight gain recommendation is the
appropriateness of the prepregnancy weight for the woman's height. A commonly
used method of evaluating the appropriateness of weight for height is the BMI.
Although weight gain does indicate risk for IUGR, this does not apply to this
patient. Weight gain should occur at a steady rate throughout the pregnancy. The
optimal rate of weight gain also depends on the stage of the pregnancy.
1. A man smokes two packs of cigarettes a day. He wants to know if smoking is
contributing to the difficulty he and his wife are having getting pregnant. The
nurse's most appropriate response is:
A. "Your sperm count seems to be okay in the first semen analysis."
B. "Only marijuana cigarettes affect sperm count."
C. "Smoking can give you lung cancer, even though it has no effect on sperm."
D. "Smoking can reduce the quality of your sperm." correct answer ANS: D
Use of tobacco, alcohol, and marijuana may affect sperm counts. "Your sperm
count seems to be okay in the first semen analysis" is inaccurate. Sperm counts
vary from day to day and depend on emotional and physical status and sexual
activity. A single analysis may be inconclusive. A minimum of two analyses must
be performed several weeks apart to assess male fertility.
1. A new mother asks the nurse when the "soft spot" on her son's head will go
away. What is the nurse's best response, based upon her understanding of when
the anterior frontal closes?
a. 2 months
,b. 8 months
c. 12 months
d. 18 months correct answer ANS: D
The larger of the two fontanels, the anterior fontanel, closes by 18 months after
birth. The posterior fontanel closes at 6 to 8 weeks. The remaining three options
are too early for the anterior fontanel to close.
1. A tiered system of categorizing FHR has been recommended by regulatory
agencies. Nurses, midwives, and physicians who care for women in labor must
have a working knowledge of fetal monitoring standards and understand the
significance of each category. These categories include: (Select all that apply.)
a. reassuring.
b. Category I.
c. Category II.
d. nonreassuring.
e. Category III. correct answer ANS: B, C, E
The three tiered system of FHR tracings include Category I, II, and III. Category I is
a normal tracing requiring no action. Category II FHR tracings are indeterminate.
This category includes tracings that do not meet Category I or III criteria. Category
III tracings are abnormal and require immediate intervention.
, 1. A woman arrives at the clinic seeking confirmation that she is pregnant. The
following information is obtained: She is 24 years old with a body mass index
(BMI) of 17.5. She admits to having used cocaine "several times" during the past
year and drinks alcohol occasionally. Her blood pressure (BP) is 108/70 mm Hg,
her pulse rate is 72 beats/min, and her respiratory rate is 16 breaths/min. The
family history is positive for diabetes mellitus and cancer. Her sister recently gave
birth to an infant with a neural tube defect (NTD). Which characteristics place the
woman in a high risk category?
A. Blood pressure, age, and BMI
B. Drug/alcohol use, age, and family history
C. Family history, blood pressure, and BMI
D. Family history, BMI, and drug/alcohol abuse correct answer ANS: D
Her family history of NTD, low BMI, and substance abuse all are high risk factors
of pregnancy. The woman's BP is normal, and her age does not put her at risk. Her
BMI is low and may indicate poor nutritional status, which would be a high risk.
The woman's drug/alcohol use and family history put her in a high risk category,
but her age does not. The woman's family history puts her in a high risk category.
Her BMI is low and may indicate poor nutritional status, which would be high risk.
Her BP is normal.
1. A woman's obstetric history indicates that she is pregnant for the fourth time
and all of her children from previous pregnancies are living. One was born at 39
weeks of gestation, twins were born at 34 weeks of gestation, and another child
was born at 35 weeks of gestation. What is her gravidity and parity using the
GTPAL system?
a. 3-1-1-1-3
b. 4-1-2-0-4
c. 3-0-3-0-3
