• The fetal circulatory structure that connects the pulmonary artery with the descending

aorta is known as which of the following?a. Ductus venosusb. Foramen ovalec. Ductus arteriosusd. Internal iliac artery

ANS: c

Feedback

• The ductus venosus connects the umbilical vein to the inferior vena cava.
• The foramen ovale is the opening between the right and left atria.
• Correct.
• The internal iliac artery connects the external iliac artery to the umbilical artery.

• A woman at 40 weeks’ gestation has a diagnosis of oligohydramnios. Which of the

following statements related to oligohydramnios is correct?a. It indicates that there is a 25% increase in amniotic fluid.b. It indicates that there is a 25% reduction of amniotic fluid.c. It indicates that there is a 50% increase in amniotic fluid.d. It indicates that there is a 50% reduction of amniotic fluid.

ANS: d

Feedback

• Oligohydramnios is a decrease, not an increase in amniotic fluid.
• Oligohydramnios is a 50% reduction in amniotic fluid.
• Oligohydramnios is a decrease, not an increase in amniotic fluid.
• Correct. Oligohydramnios refers to a decreased amount of amniotic fluid of less than 500

mL at term or 50% reduction of normal amounts.KEY: Integrated Process: Clinical Problem Solving | Cognitive Level: Application | Content Area: Maternity | Client Need: Reduction of Risk Potential | Difficulty Level: Moderate

• A diagnostic test commonly used to assess problems of the fallopian tubes is:a.

Endometrial biopsyb. Ovarian reserve testingc. Hysterosalpingogramd. Screening for sexually transmitted infections 2 / 4

ANS: c

Feedback

• Endometrial biopsy provides information on the response of the uterus to hormonal

signals.

• Ovarian reserve testing is used to assess ovulatory functioning.
• Correct. Hysterosalpingogram provides information on the endocervical canal, uterine

cavity, and fallopian tubes.

• STIs can cause adhesions within the fallopian tubes, but screening cannot confirm that

adhesions are present.KEY: Integrated Process: Teaching and Learning | Cognitive Level: Knowledge | Content Area: Maternity | Client Need: Safe and Effective Care Environment | Difficulty Level: Moderate

• The nurse is interviewing a gravid woman during the first prenatal visit. The woman

confides to the nurse that she lives with a number of pets. The nurse should advise the woman to be especially careful to refrain from coming in contact with the stool of which of the pets?

• Cat
• Dog
• Hamster
• Bird

ANS: a

Feedback

• The patient should refrain from coming in direct contact with cat feces. Cats often harbor

toxoplasmosis, a teratogenic illness.

• No pathology has been associated with the feces of pet dogs.
• No pathology has been associated with the feces of pet hamsters.
• No pathology has been associated with the feces of pet birds.

• A client is to take Clomiphene Citrate for infertility. Which of the following is the expected

action of this medication?

• Decrease the symptoms of endometriosis
• Increase serum progesterone levels
• Stimulate release of FSH and LH
• Reduce the acidity of vaginal secretions

• The nurse takes the history of a client, G2 P1, at her first prenatal visit. The client is

referred to a genetic counselor, due to her previous child having a diagnosis of .

• Unilateral amblyopia
• Subdural hematoma
• Sickle cell anemia
• Glomerular nephritis

• A nurse is teaching a woman about her menstrual cycle. The nurse states that

is the most important change that happens during the secretory phase of the menstrual cycle.

• Maturation of the graafian follicle
• Multiplication of the fimbriae
• Secretion of human chorionic gonadotropin
• Proliferation of the endometrium 3 / 4

• An ultrasound of a fetus’ heart shows that “normal fetal circulation is occurring.” Which of

the following statements is consistent with the finding?

• A right to left shunt is seen between the atria.
• Blood is returning to the placenta via the umbilical vein.
• Blood is returning to the right atrium from the pulmonary system.
• A right to left shunt is seen between the umbilical arteries.

• The clinic nurse knows that the part of the endometrial cycle occurring from ovulation to

just prior to menses is known as the:

• Menstrual phase
• Proliferative phase
• Secretory phase
• Ischemic phase

• A clinic nurse explains to the pregnant woman that the amount of amniotic fluid present

at 24 weeks’ gestation is approximately:

• 500 mL
• 750 mL
• 800 mL
• 1000 mL

• Information provided by the nurse that addresses the function of the amniotic fluid is that

the amniotic fluid helps the fetus to maintain a normal body temperature and also:

• Facilitates asymmetrical growth of the fetal limbs
• Cushions the fetus from mechanical injury
• Promotes development of muscle tone
• Promotes adherence of fetal lung tissue

• During preconception counseling, the clinic nurse explains that the time period when the

fetus is most vulnerable to the effects of teratogens occurs from:

• 2 to 8 weeks
• 4 to12 weeks
• 5 to 10 weeks
• 6 to 15 weeks

15. A major fetal development characteristic at 16 weeks’ gestation is:

• The average fetal weight is 450 grams
• Lanugo covers entire body
• Brown fat begins to develop
• Teeth begin to form

• Karen, a 26-year-old woman, has come for preconception counseling and asks about

caring for her cat as she has heard that she “should not touch the cat during pregnancy.”

The clinic nurse’s best response is:

• It is best if someone other than you changes the cat’s litter pan during pregnancy so that

you have no risk of toxoplasmosis during pregnancy.

• It is important to have someone else change the litter pan during pregnancy and also

avoid consuming raw vegetables.

• Have you had any “flu-like” symptoms since you got your cat? If so, you may have already

had toxoplasmosis and there is nothing to worry about.

• Toxoplasmosis is a concern during pregnancy, so it is important to have someone else

change the cat’s litter pan and also to avoid consuming uncooked meat.
