NUR 335 Exam 1: Maternal Health Theory & Application
V1 - Arizona College Updated and Latest Questions and
Correct Answers with Rationale
1. A woman at 10 weeks gestation reports morning sickness. Which of the following is a presumptive sign of
pregnancy?
A. Positive pregnancy test
B. Hegar’s sign
C. Amenorrhea
D. Fetal heart tones
Ans: C
Explanation: Presumptive signs are subjective changes that the woman experiences herself. Amenorrhea
is one of the earliest presumptive signs noticed by many women. While these signs may suggest
pregnancy, they can also be caused by other conditions. Probable signs are objective findings observed by
a healthcare provider, like a pregnancy test. Positive signs are those that definitively confirm a live fetus
exists.
2. According to Naegele’s rule, if a patient’s last menstrual period (LMP) was June 10th, what is the
estimated date of delivery (EDD)?
A. April 17th
B. March 10th
C. March 3rd
D. March 17th
Ans: D
,Explanation: Naegele’s rule is a standard method used to calculate the estimated date of birth. To apply
it, you subtract three months from the first day of the last menstrual period. Then, you add seven days
and finally add one year to that date. In this specific scenario, June minus three months leads to March.
Adding seven days to June 10th results in an expected delivery date of March 17th.
3. What is the primary function of the amniotic fluid during pregnancy?
A. Protecting the fetus from mechanical injury
B. Providing nutrition to the fetus
C. Transporting oxygen to the fetal blood
D. Filtering waste products from the fetus
Ans: A
Explanation: Amniotic fluid serves as a vital cushion to protect the fetus from external physical trauma.
It also helps maintain a constant body temperature for the developing baby. This fluid allows for
symmetrical growth and prevents the fetus from adhering to the membranes. It provides the necessary
space for fetal movement and musculoskeletal development. Nutrition and oxygen are primarily
provided by the placenta, not the amniotic fluid.
4. Which hormone is responsible for maintaining the endometrial lining during early pregnancy?
A. Estrogen
B. Progesterone
C. Luteinizing hormone
D. Prolactin
Ans: B
, Explanation: Progesterone is often called the hormone of pregnancy because it supports the uterine
environment. It is initially produced by the corpus luteum and later by the placenta. This hormone
prevents uterine contractions and maintains the thickness of the endometrial lining. High levels of
progesterone are essential to prevent early miscarriage. While estrogen also rises, it is progesterone that
primarily stabilizes the pregnancy.
5. A nurse is assessing a patient at 20 weeks gestation. Where should the fundal height be located?
A. At the symphysis pubis
B. Halfway between the symphysis pubis and umbilicus
C. At the xiphoid process
D. At the level of the umbilicus
Ans: D
Explanation: Measuring fundal height is a standard practice to assess fetal growth and gestational age.
At approximately 20 weeks, the top of the uterus is usually at the level of the umbilicus. This
measurement in centimeters typically corresponds to the number of weeks of gestation. It provides a
simple and effective way for clinicians to track progress during prenatal visits. Any significant variation
from this expected height may require further investigation via ultrasound.
6. Which of the following is considered a positive sign of pregnancy?
A. Ballottement
B. Chadwick’s sign
C. Fetal heart sounds heard by Doppler
D. Morning sickness
Ans: C
