Chapter 20 Flashcards
- A woman gave birth to an infant boy 10 hours ago. Where does the nurse expect to locate this woman’s fundus?
a. 1 centimeter above the umbilicus
b. 2 centimeters below the umbilicus
c. Midway between the umbilicus and the symphysis pubis
d. Nonpalpable abdominally
ANS: A
The fundus descends approximately 1 to 2 cm every 24 hours. Within 12 hours after delivery the fundus may be approximately 1 cm above the umbilicus. By the sixth postpartum week the fundus is normally halfway between the symphysis pubis and the umbilicus. The fundus should be easily palpated using the maternal umbilicus as a reference point.
- What are the most common causes for subinvolution of the uterus?
a. Postpartum hemorrhage and infection
b. Multiple gestation and postpartum hemorrhage
c. Uterine tetany and overproduction of oxytocin
d. Retained placental fragments and infection
ANS: D
Subinvolution is the failure of the uterus to return to a nonpregnant state. The most common causes of subinvolution are retained placental fragments and infection. Subinvolution may be caused by an infection and result in hemorrhage. Multiple gestations may cause uterine atony, resulting in postpartum hemorrhaging. Uterine tetany and overproduction of oxytocin do not cause subinvolution.
- Which client is most likely to experience strong and uncomfortable afterpains?
a. A woman who experienced oligohydramnios
b. A woman who is a gravida 4, para 4-0-0-4
c. A woman who is bottle-feeding her infant
d. A woman whose infant weighed 5 pounds, 3 ounces
ANS: B
Afterpains are more common in multiparous women. In a woman who experienced polyhydramnios, afterpains are more noticeable because the uterus was greatly distended. Breastfeeding may cause the afterpains to intensify. In a woman who delivered a large infant, afterpains are more noticeable because the uterus was greatly distended.
- A woman gave birth to a healthy infant boy 5 days ago. What type of lochia does the nurse expect to find when evaluating this client?
a. Lochia rubra
b. Lochia sangra
c. Lochia alba
d. Lochia serosa
ANS: D
Lochia serosa, which consists of blood, serum, leukocytes, and tissue debris, generally occurs around day 3 or 4 after childbirth. Lochia rubra consists of blood and decidual and trophoblastic debris. The flow generally lasts 3 to 4 days and pales, becoming pink or brown. Lochia sangra is not a real term. Lochia alba occurs in most women after day 10 and can continue up to 6 weeks after childbirth.
- Which hormone remains elevated in the immediate postpartum period of the breastfeeding woman?
a. Estrogen
b. Progesterone
c. Prolactin
d. Human placental lactogen
ANS: C
Prolactin levels in the blood progressively increase throughout pregnancy. In women who breastfeed, prolactin levels remain elevated into the sixth week after birth. Estrogen levels decrease significantly after expulsion of the placenta, reaching their lowest levels 1 week into the postpartum period. Progesterone levels decrease significantly after expulsion of the placenta, reaching their lowest levels 1 week into the postpartum period. Human placental lactogen levels dramatically decrease after expulsion of the placenta.
- Two days ago a woman gave birth to a full-term infant. Last night she awakened several times to urinate and noted that her gown and bedding were wet from profuse diaphoresis. Which physiologic alteration is the cause for the diaphoresis and diuresis that this client is experiencing?
a. Elevated temperature caused by postpartum infection
b. Increased basal metabolic rate after giving birth
c. Loss of increased blood volume associated with pregnancy
d. Increased venous pressure in the lower extremities
ANS: C
Within 12 hours of birth, women begin to lose the excess tissue fluid that has accumulated during pregnancy. One mechanism for reducing these retained fluids is the profuse diaphoresis that often occurs, especially at night, for the first 2 or 3 days after childbirth. Postpartal diuresis is another mechanism by which the body rids itself of excess fluid. An elevated temperature causes chills and possibly dehydration, not diaphoresis and diuresis. Diaphoresis and diuresis are sometimes referred to as reversal of the water metabolism of pregnancy, not as the basal metabolic rate. Postpartal diuresis may be caused by the removal of increased venous pressure in the lower extremities.
- Which term best describes the interval between the birth of the newborn and the return of the reproductive organs to their normal nonpregnant state?
a. Involutionary period because of what happens to the uterus
b. Lochia period because of the nature of the vaginal discharge
c. Mini-tri period because it lasts only 3 to 6 weeks
d. Puerperium, or fourth trimester of pregnancy
ANS: D
The puerperium, also called the fourth trimester or the postpartum period of pregnancy, is the final period of pregnancy and lasts approximately 3 to 6 weeks. Involution marks the end of the puerperium. Lochia refers to the various vaginal discharges during the puerperium.
- A woman gave birth to a 7-pound, 6-ounce infant girl 1 hour ago. The birth was vaginal and the estimated blood loss (EBL) was 1500 ml. When evaluating the woman’s vital signs, which finding would be of greatest concern to the nurse?
a. Temperature 37.9° C, heart rate 120 beats per minute (bpm), respirations 20 breaths per minute, and blood pressure 90/50 mm Hg
b. Temperature 37.4° C, heart rate 88 bpm, respirations 36 breaths per minute, and blood pressure 126/68 mm Hg
c. Temperature 38° C, heart rate 80 bpm, respirations 16 breaths per minute, and blood pressure 110/80 mm Hg
d. Temperature 36.8° C, heart rate 60 bpm, respirations 18 breaths per minute, and blood pressure 140/90 mm Hg
ANS: A
An EBL of 1500 ml with tachycardia and hypotension suggests hypovolemia caused by excessive blood loss. Temperature 37.4° C, heart rate 88 bpm, respirations 36 breaths per minute, and blood pressure 126/68 mm Hg are normal vital signs except for an increased respiratory rate, which may be secondary to pain from the birth. Temperature 38° C, heart rate 80 bpm, respirations 16 breaths per minute, and blood pressure 110/80 mm Hg are normal vital signs except for the temperature, which may increase to 38° C during the first 24 hours as a result of the dehydrating effects of labor. Temperature 36.8° C, heart rate 60 bpm, respirations 18 breaths per minute, and blood pressure 140/90 mm Hg are normal vital signs, although the blood pressure is slightly elevated, which may be attributable to the use of oxytocic medications.
- A client is concerned that her breasts are engorged and uncomfortable. What is the nurse’s explanation for this physiologic change?
a. Overproduction of colostrum
b. Accumulation of milk in the lactiferous ducts and glands
c. Hyperplasia of mammary tissue
d. Congestion of veins and lymphatic vessels
ANS: D
Breast engorgement is caused by the temporary congestion of veins and lymphatic vessels. An overproduction of colostrum, an accumulation of milk in the lactiferous ducts and glands, and hyperplasia of mammary tissue do not cause breast engorgement.
- After delivery, excess hypertrophied tissue in the uterus undergoes a period of self-destruction. What is the correct term for this process?
a. Autolysis
b. Subinvolution
c. Afterpains
d. Diastasis
ANS: A
Autolysis is caused by a decrease in hormone levels. Subinvolution is failure of the uterus to return to a nonpregnant state. Afterpains are caused by uterine cramps 2 to 3 days after birth. Diastasis refers to the separation of muscles.
- Which statement regarding the postpartum uterus is correct?
a. At the end of the third stage of labor, the postpartum uterus weighs approximately 500 g.
b. After 2 weeks postpartum, it should be abdominally nonpalpable.
c. After 2 weeks postpartum, it weighs 100 g.
d. Postpartum uterus returns to its original (prepregnancy) size by 6 weeks postpartum.
ANS: B
The uterus does not return to its original size. At the end of the third stage of labor, the uterus weighs approximately 1000 g. After 2 weeks postpartum, the uterus weighs approximately 350 g. The normal self-destruction of excess hypertrophied tissue accounts for the slight increase in uterine size after each pregnancy.
- A client asks the nurse when her ovaries will begin working again. Which explanation by the nurse is most accurate?
a. Almost 75% of women who do not breastfeed resume menstruating within 1 month after birth.
b. Ovulation occurs slightly earlier for breastfeeding women.
c. Because of menstruation and ovulation schedules, contraception considerations can be postponed until after the puerperium.
d. The first menstrual flow after childbirth usually is heavier than normal.
ANS: D
The first flow is heavier, but within three or four cycles, the flow is back to normal. Ovulation can occur within the first month, but for 70% of nonlactating women, it returns in approximately 3 months. Women who are breastfeeding take longer to resume ovulation. Because many women ovulate before their first postpartum menstrual period, contraceptive options need to be discussed early in the puerperium.
- The nurse should be cognizant of which postpartum physiologic alteration?
a. Cardiac output, pulse rate, and stroke volume all return to prepregnancy normal values within a few hours of childbirth.
b. Respiratory function returns to nonpregnant levels by 6 to 8 weeks after childbirth.
c. Lowered white blood cell count after pregnancy can lead to false-positive results on tests for infections.
d. Hypercoagulable state protects the new mother from thromboembolism, especially after a cesarean birth.
ANS: B
Respirations should decrease to within the woman’s normal prepregnancy range by 6 to 8 weeks after childbirth. Stroke volume increases and cardiac output remains high for a couple of days. However, the heart rate and blood pressure quickly return to normal. Leukocytosis increases 10 to 12 days after childbirth, which can obscure the diagnosis of acute infections, producing false-negative test results. The hypercoagulable state increases the risk of thromboembolism, especially after a cesarean birth.
- Which condition, not uncommon in pregnancy, is likely to require careful medical assessment during the puerperium?
a. Varicosities of the legs
b. Carpal tunnel syndrome
c. Periodic numbness and tingling of the fingers
d. Headaches
ANS: D
Headaches in the postpartum period can have a number of causes, some of which deserve medical attention. Total or nearly total regression of varicosities is expected after childbirth. Carpal tunnel syndrome is relieved in childbirth when the compression on the median nerve is lessened. Periodic numbness of the fingers usually disappears after childbirth unless carrying the baby aggravates the condition.
- Several delivery changes in the integumentary system that appear during pregnancy disappear after birth, although not always completely. What change is almost certain to be completely reversed?
a. Nail brittleness
b. Darker pigmentation of the areolae and linea nigra
c. Striae gravidarum on the breasts, abdomen, and thighs
d. Spider nevi
ANS: A
The nails return to their prepregnancy consistency and strength. Some women have permanent darker pigmentation of the areolae and linea nigra. Striae gravidarum (stretch marks) usually do not completely disappear. For some women, spider nevi persist indefinitely.
