The nurse explains that implantation is the embedding of the fertilized ovum in the uterine mucosa. This implantation usually occurs in the:

• lower uterine wall.

• side of the uterus.

• fundus of the uterus.

• body of the uterus.

The nurse uses a diagram to show the development of the embryonic stage of pregnancy, which usually lasts about

• 3 weeks

• 4 weeks

• 6 weeks

• 8 weeks

The nurse is concerned about the patient who is in her first trimester of pregnancy and has been exposed to German measles, because this disease is capable of:

• causing a spontaneous abortion.

• causing birth defects.

• causing high fever and convulsions.

• interfering with placental implantation

The nurse explains that the placenta functions as an endocrine gland, secreting estrogen, progesterone, and:

• follicle-stimulating hormone (FSH)

• alpha-fetoprotein (AFP)

• human chorionic gonadotropin (HCG).

• luteinizing hormone (LH).

When lecturing to a class of prenatal women, the nurse explains that the fetus is protected from most bacterial invasions by the:

• yolk sac

• cotyledons

• placental barrier

• chorionic villa

A pregnant woman arrives for a visit to the physician. The nurse applies an amplified stethoscope to the abdomen and can hear the fetal heart tone. The nurse assesses that the fetus is at the fetal developmental week of:

• 10

• 12

• 14

• 16

The father asks how soon the sex of the baby can be confirmed. The nurse answers that the genitalia are well defined at:

• week 9

• week 3

• Conception

• week 8

The physician decides to send the mother for a test to determine the fetal lung maturity. This fetal well-being test is called a(n):

• biophysical profile.

• alpha-fetoprotein.

• amniocentesis.

• ultrasound.

The nurse uses a diagram to show how the arteries in the umbilical cord carry:

• nutrients to the fetus from the placenta.

• oxygenated blood to perfuse the placenta.

• antibodies from the mother to the fetus.

• deoxygenated blood back to the placenta.

To assess an accurate fundal height, the nurse should instruct the patient to:

• press her lower back against the examination table.

• empty her bladder

• take a deep breath and hold it.

• bear down.
