Answers and Rationales

1. Answer: A. FSH and LH are released from the anterior pituitary gland. FSH and LH, when stimulated by gonadotropin-releasing hormone from the hypothalamus, are released from the anterior pituitary gland to stimulate follicular growth and development, growth of the graafian follicle, and production of progesterone.
2. Answer: B. Two umbilical arteries and one umbilical vein. Blood pumped by the embryo’s heart leaves the embryo through two umbilical arteries. Once oxygenated, the blood then is returned by one umbilical vein. Arteries carry deoxygenated blood and waste products from the fetus, and veins carry oxygenated blood and provide oxygen and nutrients to the fetus.
3. Answer: C. 150 BPM. The fetal heart rate depends in gestational age and ranges from 160-170 BPM in the first trimester but slows with fetal growth to 120-160 BPM near or at term. At or near term, if the fetal heart rate is less than 120 or more than 160 BPM with the uterus at rest, the fetus may be in distress.
4. Answer: C. June 26, 2014. Accurate use of Naegele’s rule requires that the woman have a regular 28-day menstrual cycle. Add 7 days to the first day of the last menstrual period, subtract three months, and then add one year to that date.
5. Answer: B. G = 2, T = 0, P = 1, A = 0, L =1. Pregnancy outcomes can be described with the acronym GTPAL.
   • “G” is Gravidity, the number of pregnancies.
   • “T” is term births, the number of born at term (38 to 41 weeks).
   • “P” is preterm births, the number born before 38 weeks gestation.
   • “A” is abortions or miscarriages, included in “G” if before 20 weeks gestation, included in parity if past 20 weeks AOE.
   • “L” is live births, the number of births of living children.
   • Therefore, a woman who is pregnant with twins and has a child has a gravida of 2. Because the child was delivered at 37 weeks, the number of preterm births is 1, and the number of term births is 0. The number of abortions is 0, and the number of live births is 1.
6. Answer: B. Fetal heart rate of 180 BPM. The normal range of the fetal heart rate depends on gestational age. The heart rate is usually 160-170 BPM in the first trimester and slows with fetal growth, near and at term, the fetal heart rate ranges from 120-160 BPM. The other options are expected.
7. Answer: A. A softening of the cervix. In the early weeks of pregnancy the cervix becomes softer as a result of increased vascularity and hyperplasia, which causes the Goodell’s sign.
8. Answer: C. “It is the fetal movement that is felt by the mother.” Quickening is fetal movement and may occur as early as the 16th and 18th week of gestation, and the mother first notices subtle fetal movements that gradually increase in intensity. Braxton Hicks contractions are irregular, painless contractions that may occur throughout the pregnancy. A thinning of the lower uterine segment occurs about the 6th week of pregnancy and is called Hegar’s sign.
9. Answer: D. Initiating a gentle upward tap on the cervix. Ballottement is a technique of palpating a floating structure by bouncing it gently and feeling it rebound. In the technique used to palpate the fetus, the examiner places a finger in the vagina and taps gently upward, causing the fetus to rise. The fetus then sinks, and the examiner feels a gentle tap on the finger.
10. Answers: A, D, E, and F. 
    • The probable signs of pregnancy include:
      • Uterine Enlargement
      • Hegar’s sign or softening and thinning of the uterine segment that occurs at week 6.
      • Goodell’s sign or softening of the cervix that occurs at the beginning of the 2nd month
      • Chadwick’s sign or bluish coloration of the mucous membranes of the cervix, vagina and vulva. Occurs at week 6.
      • Ballottement or rebounding of the fetus against the examiner’s fingers of palpation
      • Braxton-Hicks contractions
      • Positive pregnancy test measuring for hCG.
    • Positive signs of pregnancy include:
      • Fetal Heart Rate detected by electronic device (doppler) at 10-12 weeks
      • Fetal Heart rate detected by nonelectronic device (fetoscope) at 20 weeks AOG
      • Active fetal movement palpable by the examiners
      • Outline of the fetus via radiography or ultrasound
11. Answer: A. Dorsiflex the foot while extending the knee when the cramps occur. Legs cramps occur when the pregnant woman stretches the leg and plantar flexes the foot. Dorsiflexion of the foot while extending the knee stretches the affected muscle, prevents the muscle from contracting, and stops the cramping.
12. Answer: D. Wash the breasts with warm water and keep them dry. The pregnant woman should be instructed to wash the breasts with warm water and keep them dry. The woman should be instructed to avoid using soap on the nipples and areola area to prevent the drying of tissues. Wearing a supportive bra with wide adjustable straps can decrease breast tenderness. Tight-fitting blouses or dresses will cause discomfort.
13. Answer: A. Any bleeding, such as in the gums, petechiae, and purpura. Severe Preeclampsia can trigger disseminated intravascular coagulation because of the widespread damage to vascular integrity. Bleeding is an early sign of DIC and should be reported to the M.D.
14. Answer: A. “I will maintain strict bedrest throughout the remainder of pregnancy.” Strict bed rest throughout the remainder of pregnancy is not required. The woman is advised to curtail sexual activities until the bleeding has ceased, and for 2 weeks following the last evidence of bleeding or as recommended by the physician. The woman is instructed to count the number of perineal pads used daily and to note the quantity and color of blood on the pad. The woman also should watch for the evidence of the passage of tissue.
15. Answer: C. “I need to drink unpasteurized milk only.” All pregnant women should be advised to do the following to prevent the development of toxoplasmosis. Women should be instructed to cook meats thoroughly, avoid touching mucous membranes and eyes while handling raw meat; thoroughly wash all kitchen surfaces that come into contact with uncooked meat, wash the hands thoroughly after handling raw meat; avoid uncooked eggs and unpasteurized milk; wash fruits and vegetables before consumption, and avoid contact with materials that possibly are contaminated with cat feces, such as cat litter boxes, sandboxes, and garden soil.
16. Answer: C. The client complains of a headache and blurred vision. If the client complains of a headache and blurred vision, the physician should be notified because these are signs of worsening Preeclampsia.
17. Answer: C. “I need to avoid exercise because of the negative effects of insulin production.” Exercise is safe for the client with gestational diabetes and is helpful in lowering the blood glucose level.
18. Answer: C. Respiratory rate of 10 BPM. Magnesium sulfate depresses the respiratory rate. If the respiratory rate is less than 12 breaths per minute, the physician or other health care provider needs to be notified, and continuation of the medication needs to be reassessed. A urinary output of 20 ml in a 30 minute period is adequate; less than 30 ml in one hour needs to be reported. Deep tendon reflexes of 2+ are normal. The fetal heart rate is WNL for a resting fetus.
19. Answer: C. Clean and maintain an open airway. The immediate care during a seizure (eclampsia) is to ensure a patent airway. The other options are actions that follow or will be implemented after the seizure has ceased.
20. Answers: A Elevated blood pressure and 3 Facial edema. The three classic signs of preeclampsia are hypertension, generalized edema, and proteinuria. Increased respirations are not a sign of preeclampsia.
21. Answer: A. Being affected by Rh incompatibility. Rh incompatibility can occur when an Rh-negative mom becomes sensitized to the Rh antigen. Sensitization may develop when an Rh-negative woman becomes pregnant with a fetus who is Rh positive. During pregnancy and at delivery, some of the baby’s Rh positive blood can enter the maternal circulation, causing the woman’s immune system to form antibodies against Rh positive blood. Administration of Rho(D) immune globulin prevents the woman from developing antibodies against Rh positive blood by providing passive antibody protection against the Rh antigen.
22. Answer: D. Respirations of 10 per minute. Magnesium toxicity can occur from magnesium sulfate therapy. Signs of toxicity relate to the central nervous system depressant effects of the medication and include respiratory depression, loss of deep tendon reflexes, and a sudden drop in the fetal heart rate and maternal heart rate and blood pressure. Therapeutic levels of magnesium are 4-7 mEq/L. Proteinuria of +3 would be noted in a client with preeclampsia.
23. Answer: C. Seizures do not occur. For a client with preeclampsia, the goal of care is directed at preventing eclampsia (seizures). Magnesium sulfate is an anticonvulsant, not an antihypertensive agent. Although a decrease in blood pressure may be noted initially, this effect is usually transient. Ankle clonus indicated hyperreflexia and may precede the onset of eclampsia. Scotomas are areas of complete or partial blindness. Visual disturbances, such as scotomas, often precede an eclamptic seizure.
24. Answers: C, D, E, F, and G. When caring for a client receiving magnesium sulfate therapy, the nurse would monitor maternal vital signs, especially respirations, every 30-60 minutes and notify the physician if respirations are less than 12, because this would indicate respiratory depression. Calcium gluconate is kept on hand in case of magnesium sulfate overdose, because calcium gluconate is the antidote for magnesium sulfate toxicity. Deep tendon reflexes are assessed hourly. Cardiac and renal function is monitored closely. The urine output should be maintained at 30 ml per hour because the medication is eliminated through the kidneys.
25. Answer: A. Administer RhoGAM within 72 hours. RhoGAM is given within 72 hours postpartum if the client has not been sensitized already.
26. Answer: B. Blood level of LH is too high.  It is the surge of LH secretion in mid cycle that is responsible for ovulation.
27. Answer: C. Preparation of the uterus to receive a fertilized egg. Progesterone stimulates differentiation of the endometrium into a secretory type of tissue.
28. Answer: B. Eighth week to the time of birth.  In the first 7-14 days the ovum is known as a blastocyst; it is called an embryo until the eighth week; the developing cells are then called a fetus until birth.
29. Answer: A. Placenta. When placental formation is complete, around the 16th week of pregnancy; it produces estrogen and progesterone.
30. Answer: C. An increase in blood volume. The blood volume increases by approximately 40-50% during pregnancy. The peak blood volume occurs between 30 and 34 weeks of gestation. The hematocrit decreases as a result of the increased blood volume.
31. Answer: D. Chadwick’s sign. A purplish color results from the increased vascularity and blood vessel engorgement of the vagina.
32. Answer: C. G5 T2 P1 A1 L4. 5 pregnancies; 2 term births; twins count as 1; one abortion; 4 living children.
33. Answer: D. Shortness of breath on exertion. This is an expected cardiopulmonary adaptation during pregnancy; it is caused by an increased ventricular rate and elevated diaphragm.
34. Answer: B. An increase of 300 calories a day. This is the recommended caloric increase for adult women to meet the increased metabolic demands of pregnancy.
35. Answer: A. Acute hemolytic disease. When an Rh negative mother carries an Rh positive fetus there is a risk for maternal antibodies against Rh positive blood; antibodies cross the placenta and destroy the fetal RBC’s.
36. Answer: B. Production of estrogen. The increase of estrogen during pregnancy causes hyperplasia of the vaginal mucosa, which leads to increased production of mucus by the endocervical glands. The mucus contains exfoliated epithelial cells.
37. Answer: C. Neural tube defects. The alpha-fetoprotein test detects neural tube defects and Down syndrome.
38. Answer: B. Walk around until they subside. Ambulation relieves Braxton Hicks.
39. Answer: B. Cause decreased placental perfusion. This is because impedance of venous return by the gravid uterus, which causes hypotension and decreased systemic perfusion.
40. Answer: A. Prolactin. Prolactin is the hormone from the anterior pituitary gland that stimulates mammary gland secretion. Oxytocin, a posterior pituitary hormone, stimulates the uterine musculature to contract and causes the “let down” reflex.
41. Answer: D. “Snowstorm” pattern on ultrasound with no fetus or gestational sac. The chorionic villi of a molar pregnancy resemble a snowstorm pattern on ultrasound. Bleeding with a hydatidiform mole is often dark brown and may occur erratically for weeks or months.
42. Answer: D. Telangiectasias. The dilated arterioles that occur during pregnancy are due to the elevated level of circulating estrogen. The linea nigra is a pigmented line extending from the symphysis pubis to the top of the fundus during pregnancy.
43. Answer: C. Physiologic anemia. Hemoglobin and hematocrit levels decrease during pregnancy as the increase in plasma volume exceeds the increase in red blood cell production.
