1. A client at 12 weeks gestation asks the nurse when she will be able
to feel fetal movement. The nurse's best response is:
• A) "You should feel movement by 8 weeks."
• B) "Quickening typically occurs between 16-20 weeks."
• C) "Fetal movement is felt at 24 weeks."
• D) "You will feel movement at 12 weeks."
Answer: B. Quickening (first fetal movements felt by the mother)
typically occurs between 16-20 weeks gestation in primigravidas and
slightly earlier in multigravidas.
,2. A client at 8 weeks gestation reports nausea and vomiting. Which
instruction should the nurse provide?
• A) "Eat three large meals per day."
• B) "Avoid eating crackers before getting out of bed."
• C) "Eat small, frequent meals and avoid fatty foods."
• D) "Drink large amounts of fluids with meals."
Answer: C. Small, frequent meals and avoiding fatty, spicy, or greasy
foods help manage nausea and vomiting in early pregnancy. Dry crackers
before rising can also help.
3. The nurse is calculating the estimated date of birth (EDB) using
Naegele's rule for a client whose last menstrual period (LMP) was
January 15. What is the EDB?
• A) October 22
• B) October 15
• C) November 22
• D) September 22
Answer: A. Naegele's rule: Add 7 days to the first day of LMP and
subtract 3 months. January 15 + 7 days = January 22; January 22 minus 3
months = October 22.
4. A client at 10 weeks gestation asks about the purpose of the fetal
heartbeat. The nurse explains that the fetal heart develops at
approximately:
, • A) 2 weeks
• B) 4 weeks
• C) 6 weeks
• D) 8 weeks
Answer: B. The fetal heart begins to develop and beat at approximately 4
weeks gestation (22-23 days). It is detectable by ultrasound at 6-7
weeks.
5. A client at 16 weeks gestation is concerned about weight gain. The
nurse explains that recommended weight gain for a normal BMI
woman is:
• A) 15-25 pounds
• B) 25-35 pounds
• C) 28-40 pounds
• D) 11-20 pounds
Answer: B. Recommended weight gain for a woman with a normal BMI
(18.5-24.9) is 25-35 pounds.
6. During the first trimester, the nurse expects which of the following
laboratory findings?
• A) Decreased hemoglobin
• B) Increased hematocrit
• C) Decreased platelet count
• D) Increased red blood cell count
, Answer: A. During pregnancy, hemoglobin and hematocrit decrease due
to hemodilution (increased plasma volume). Platelet count typically
remains stable or slightly decreases.
7. A client at 20 weeks gestation reports feeling "fluttering"
movements. The nurse documents this as:
• A) Lightening
• B) Ballottement
• C) Quickening
• D) Braxton Hicks
Answer: C. Quickening is the first perception of fetal movement by the
mother, typically felt at 16-20 weeks.
8. The nurse is assessing a client at 24 weeks gestation. Which
finding is expected?
• A) Fundal height at the umbilicus
• B) Fundal height at the xiphoid process
• C) Fundal height at the symphysis pubis
• D) Fundal height at the umbilicus (20 weeks) and 24 cm at 24
weeks
Answer: D. At 20 weeks, the fundus is at the umbilicus. Fundal height in
centimeters approximately equals weeks of gestation (24 weeks = 24
cm).
