CORRECT ANSWERS GRADE A+
1. During a vaginal exam, the nurse notes that the lower uterine segment is softened. The nurse
documents this finding as:
A. Hegar sign.
B. Goodell sign.
C. Chadwick sign.
D. Ortolani sign. Answer: A
Rationale: Hegar sign refers to the softening of the lower uterine segment or isthmus. Bluish
coloration of the cervix is termed Chadwick sign. Goodell sign refers to the softening of the
cervix. Ortolani sign is a maneuver done to identify developmental dysplasia of the hip in
infants.
2. The nurse teaches a primigravida client that lightening occurs about 2 weeks before the onset
of labor. What will the mother likely experience at that time?
A. dysuria
B. dyspnea
C. constipation
D. urinary frequency Answer: D
Rationale: Lightening refers to the descent of the fetal head into the pelvis and engagement. With
this descent, pressure on the diaphragm decreases, easing breathing, but pressure on the bladder
increases, leading to urinary frequency. Dysuria might indicate a urinary tract infection.
Constipation may occur throughout pregnancy due to decreased peristalsis, but it is unrelated to
lightening.
3. A gravida 2 para 1 client in the 10th week of her pregnancy says to the nurse, "I've never
urinated as often as I have for the past three weeks." Which response would be most appropriate
for the nurse to make?
A. "Having to urinate so often is annoying. I suggest that you watch how much fluid you are
drinking and limit it."
B. "You shouldn't be urinating this frequently now; it usually stops by the time you're eight
weeks pregnant. Is there anything else bothering you?"
C. "By the time you are 12 weeks pregnant, this frequent urination should really decrease, but it
is likely to return toward the end of your pregnancy."
D. "Women having their second child generally don't have frequent urination. Are you
experiencing any burning sensations?" C
4. In a client's seventh month of pregnancy, she reports feeling "dizzy, like I'm going to pass out,
when I lie down flat on my back." The nurse explains that this is due to:
A. pressure of the gravid uterus on the vena cava.
B. a 50% increase in blood volume.
,C. physiologic anemia due to hemoglobin decrease.
D. pressure of the presenting fetal part on the diaphragm. Answer: A
Rationale: The client is describing symptoms of supine hypotension syndrome, which occurs
when the heavy gravid uterus falls back against the superior vena cava in the supine position.
The vena cava is compressed, reducing venous return, cardiac output, and blood pressure, with
increased orthostasis. The increased blood volume and physiologic anemia are unrelated to the
client's symptoms. Pressure on the diaphragm would lead to dyspnea.
5. A primiparous client is being seen in the clinic for her first prenatal visit. It is determined that
she is 11 weeks pregnant. The nurse develops a teaching plan to educate the client about what
she will most likely experience during this period. Which possible effect would the nurse
include?
A. ankle edema
B. urinary frequency
C. backache
D. hemorrhoids Answer: B
Rationale: The client is in her first trimester and would most likely experience urinary frequency
as the growing uterus presses on the bladder. Ankle edema, backache, and hemorrhoids would be
more common during the later stages of pregnancy.
6. The nurse is discussing the insulin needs of a primiparous client with diabetes who has been
using insulin for the past few years. The nurse informs the client that her insulin needs will
increase during pregnancy based on the nurse's understanding that the placenta produces:
A. hCG, which increases maternal glucose levels.
B. hPL, which deceases the effectiveness of insulin.
C. estriol, which interferes with insulin crossing the placenta. D. relaxin, which decreases the
amount of insulin produced. Answer: B
Rationale: Human placental lactogen (hPL) acts as an antagonist to insulin, so the mother must
produce more insulin to overcome this resistance. If the mother has diabetes, then her insulin
need would most likely increase to meet this demand. Human chorionic gonadotropin (hCG)
does not affect insulin and glucose level. Estrogen, not estriol, is believed to oppose insulin. In
addition, insulin does not cross the placenta. Relaxin is not associated with insulin resistance.
7. When teaching a pregnant client about the physiologic changes of pregnancy, the nurse
reviews the effect of pregnancy on glucose metabolism. Which underlying reason for the effect
would the nurse include?
A. Pancreatic function is affected by pregnancy.
B. Glucose is utilized more rapidly during a pregnancy.
C. The pregnant woman increases her dietary intake.
D. Glucose moves through the placenta to assist the fetus. Answer: D
Rationale: The growing fetus has large needs for glucose, amino acids, and lipids, placing
demands on maternal glucose stores. During the first half of pregnancy, much of the maternal
glucose is diverted to the growing fetus. The pancreas continues to function during pregnancy.
However, the placental hormones can affect maternal insulin levels. The demand for glucose by
the fetus during pregnancy is high, but it is not necessarily used more rapidly. Placental
hormones, not the woman's dietary intake, play a major role in glucose metabolism during
pregnancy.
8. A nurse strongly encourages a pregnant client to avoid eating swordfish and tilefish because
these fish contain which component?
, A. excess folic acid, which could increase the risk for neural tube defects
B. mercury, which could harm the developing fetus if eaten in large amounts
C. lactose, which leads to abdominal discomfort, gas, and diarrhea
D. low-quality protein that does not meet the woman's requirements Answer: B
Rationale: Nearly all fish and shellfish contain traces of mercury, and some contain higher levels
of mercury that may harm the developing fetus if ingested by pregnant women in large amounts.
Among these fish are shark, swordfish, king mackerel, and tilefish. Folic acid is found in dark
green vegetables, baked beans, black-eyed peas, citrus fruits, peanuts, and liver. Folic acid
supplements are needed to prevent neural tube defects. Women who are lactose-intolerant
experience abdominal discomfort, gas, and diarrhea if they ingest foods containing lactose. Fish
and shellfish are an important part of a healthy diet because they contain high-quality proteins,
are low in saturated fat, and contain omega-3 fatty acids.
9. Which change in the musculoskeletal system would the nurse mention when teaching a group
of pregnant women about the physiologic changes of pregnancy?
A. ligament tightening
B. decreased swayback
C. increased lordosis
D. joint contraction Answer: C
Rationale: With pregnancy, the woman's center of gravity shifts forward, requiring a realignment
of the spinal curvatures. There is an increase in the normal lumbosacral curve (lordosis).
Ligaments of the sacroiliac joints and pubis symphysis soften and stretch. Increased swayback
and an upper spine extension to compensate for the enlarging abdomen occur. Joint relaxation
and increased mobility occur due to the influence of the hormones relaxin and progesterone.
10. Assessment of a pregnant woman reveals a pigmented line down the middle of her abdomen.
The nurse documents this as which finding?
A. linea nigra
B. striae gravidarum (stretch marks)
C. melasma (chloasma)
D. vascular spiders Answer: A
Rationale: Linea nigra refers to the darkened line of pigmentation down the middle of the
abdomen in pregnant women. Striae gravidarum refers to stretch marks, irregular reddish streaks
on the abdomen, breasts, and buttocks. Melasma (chloasma) refers to the increased pigmentation
on the face, also known as the "mask of pregnancy." Vascular spiders are small, spiderlike blood
vessels that appear usually above the waist and on the neck, thorax, face, and arms.
12. A woman suspecting she is pregnant asks the nurse about which signs would confirm her
pregnancy. The nurse would explain that which sign would confirm the pregnancy?
A. absence of menstrual period
B. abdominal enlargement
C. palpable fetal movement
D. morning sickness Answer: C
Rationale: Only positive signs of pregnancy would confirm a pregnancy. The positive signs of
pregnancy confirm that a fetus is growing in the uterus. Visualizing the fetus by ultrasound,
palpating for fetal movements, and hearing a fetal heartbeat are all signs that make the pregnancy
a certainty. Absence of menstrual period and morning sickness are presumptive signs, which can
be due to conditions other than pregnancy. Abdominal enlargement is a probable sign.
