NR 509 APEA EXAM – PREGNANCY
Question:
What is the standard instrument used to auscultate fetal heart tones?
StethoscopeDoppler
... [Show More] CorrectPre-natal monitorUltrasound
Explanation:
The Doppler fetal rate monitor is the standard instrument used for this measurement, and can detect the fetal rate (FHR) as early as 10 weeks gestation.
Question:
During pregnancy, what sound may be auscultated at the second or third intercostal space at the sternal border due to increased blood flow through the vessels?
Diastolic murmur IncorrectSystolic murmurVenous hum CorrectBruit
Explanation:
A venous hum, or continuous mammary souffle that occurs during pregnancy is due to increased blood flow through normal vessels. The mammary souffle is commonly heard during late pregnancy or lactation. It is heard loudest in the second or third intercostal space at the sternal border, and is typically both systolic and diastolic, though only the systolic component may be audible.
Question:
If regular uterine contractions occur prior to 37 weeks gestation, this could be:
a normal finding. Incorrectpreterm labor. Correctpreeclampsia.supine hypotensive syndrome.
Explanation:
Before 37 weeks, regular uterine contractions with or without pain and bleeding are abnormal, suggesting preterm labor.
Question:
Weight gain should be monitored during pregnancy. For a pregnant woman whose BMI is 18.5 - 24.9, the total weight gain should be:
11-20 pounds.15-25 pounds.25-35 pounds Correct28-40 pounds.
Explanation:
Weight gain should be closely monitored during pregnancy, as both excessive and inadequate weight gain are associated with poor birth outcomes. The pregnant woman who has a BMI of <18.5, should gain 28 - 40 pounds; BMI 18.5-24.9 should gain 25 - 35 pounds; BMI 25-29.9 should gain 15 - 25 pounds; and the obese pregnant woman should gain 11 - 20 pounds.
Question:
During pregnancy, a palpable softening of the cervical isthmus is noted. This finding is:
Hegar's sign. CorrectChadwick's sign.striae gravidarum.linea nigra.
Explanation:
Hegar’s sign is the palpable softening of the cervical isthmus, the portion of the uterus that narrows into the cervix. Increased vascularity throughout the pelvis during pregnancy gives the vagina a bluish color, known as Chadwick’s sign. As the skin over the abdomen stretches to accommodate the fetus, purplish striae gravidarum (“stretch marks”) may appear. Linea nigra is a brownish black pigmented vertical stripe along the midline skin of the abdomen.
Question:
As tension on the abdominal wall increases with advancing pregnancy, the rectus abdominis muscles may separate at the midline of the abdomen. This finding is termed:
striae gravidarum.linea nigra.adnexae.diastasis recti. Correct
Explanation:
As tension on the abdominal wall increases with advancing pregnancy, the rectus abdominis muscles may separate at the midline: this is diastasis recti. If diastasis is severe, especially in multiparous women, only a layer of skin, fascia, and peritoneum may cover the anterior uterine wall, and fetal parts may be palpable through this muscular gap.
Question:
Facial edema in a pregnant woman after 20 weeks gestation, could be:
a normal finding.suggestive of preeclampsia. Correctrenal failure. Incorrectheart failure.
Explanation:
Facial edema in a pregnant woman after 20 gestational weeks may reflect preeclampsia and should be investigated.
Question:
Weight gain should be monitored during pregnancy. For a pregnant woman whose BMI is < 18.5, the total weight gain should be:
11-20 pounds.15-25 pounds.25-35 pounds28-40 pounds. Correct
Explanation:
Weight gain should be closely monitored during pregnancy, as both excessive and inadequate weight gain are associated with poor birth outcomes. The pregnant woman who has a BMI of <18.5, should gain 28 - 40 pounds; BMI 18.5-24.9 should gain 25 - 35 pounds; BMI 25-29.9 should gain 15 - 25 pounds; and the obese pregnant woman should gain 11 - 20 pounds.
Question:
Murmurs audible during pregnancy may suggest:
preeclampsia.hypertension. Incorrectanemia. Correctpulmonary embolus.
Explanation:
Murmurs audible during pregnancy may suggest anemia. However, benign systolic murmurs can be heard in pregnant women after the first trimester.
Question:
What is the importance of prenatal care?
Determines gestational age Estimates expected date of deliveryOptimizes health and minimizes risk for mother and fetus CorrectObtain family history
Explanation:
Prenatal care focuses on optimizing health and minimizing risk for the mother and fetus. Goals of the initial prenatal visit are to confirm the pregnancy, assess the health of the mother and risks of complications, and counsel the mother about expectations for the pregnancy.
Question:
During pregnancy, which hormone promotes endometrial growth that supports the early embryo?
Progesterone IncorrectHuman chorionic gonadotropin (HCG)Estrogen CorrectHuman placental lactogen
Explanation:
Estrogen promotes endometrial growth that supports the early embryo. This hormone appears to stimulate prolactin output in the anterior lobe of the pituitary gland, which readies breast tissue for lactation. Estrogen also contributes to the hypercoagulable state that puts pregnant women at higher ris [Show Less]
