1. Late in pregnancy, a patient often develops supine hypotension because of
a. partial occlusion of the vena cava and aorta.
b. decreased peripheral collateral circulation.
c. increased blood flow to the placenta. - (answer)A
because of partial occlusion of the vena cava and aorta from the weight of the uterus. This impedes
venous return from the lower extremities although increased collateral circulation during pregnancy
helps to compensate. Remaining in the supine position for long periods of time could decrease fetal
oxygenation as well. The lateral recumbent position relieves the pressure on the vena cava and aorta,
allowing the blood pressure to increase and symptoms to decrease.
The nurse must educate the new mother that a contraindication to breast feeding is
a. fetal macrosomia.
b. type II diabetes.
c. infection with HIV/AIDS. - (answer)C
Some maternal contraindications to breastfeeding include:
-Infection with HIV/AIDS
-Use of antiretroviral medications
-Active TB not treated
-Infection with human T-cell lymphotropic virus
-Illicit drug use
-Use of chemotherapeutic agents
-Radiation therapy (may require only interruption during treatment)
-Use of other medications that pass into the breast milk and may harm the child
-Presence of herpes on the breast
-Presence of varicella lesions on the breast (may resume after lesions crust)
The initial postpartal intervention indicated for a soft boggy uterus is to
a. apply an ice compress.

b. massage the fundus until firm.
c. apply a warm compress. - (answer)B
...with the dominant hand while supporting the inferior uterus with the non-dominant hand to prevent
trauma. If the fundus does not contract with massage, then further evaluation is indicated to determine
if placental fragments remain. After the fundus becomes contracted, the nurse should push firmly
downward on the fundus to expel clots that may have pooled.
With the vibroacoustic stimulation test, stimulus with an artificial larynx or other device is applied to the
maternal abdomen for
a. 1 to 3 seconds.
b. 5 to 10 seconds.
c. 1 to 2 minutes. - (answer)A
Usually, stimulus is applied for 1-2 seconds and repeated up to 3 times with time extending to 3 seconds
in order to stimulate fetal movement. A positive or reactive finding is an increased fetal heart rate of 15
bpm or more for at least 15 seconds; however, a nonreactive result does not always indicate fetal
abnormality but indicates the need for further testing.
Absence of the Moro reflex on one side only in a neonate may indicate
a. fractured scapula.
b. cerebral palsy.
c. fractured clavicle. - (answer)C
a fractured clavicle or brachial plexus injury. Damage to the central nervous system, such as may occur
with cerebral palsy, often results in bilateral absence of the reflex. The Moro reflex is elicited by allowing
the infant's head and trunk to fall slightly backward when the infant is raised. A positive Moro reflex
includes immediate extension and abduction of the arms(and sometimes the legs) with fingers fanning
and forming a C-shape with a return of the limbs to the flexed states
In a multiparous woman, what is the lowest Bishop score that predicts labor induction will be
successful?
a. 5
b. 7

GUARANTEED PASS
c. 9 - (answer)A
In a multiparous woman, the Bishop score that predicts that labor induction will be successful is 5 or
more while it is a 9 or more for a nulliparous woman. The Bishop score is a rating system to determine
readiness for induction based on scores of 0-3 in four different measures: dilation (cm), effacement
(percentage), station (cm), and cervical consistency (firm, medium, soft), and cervical position
(posterior, mid position, anterior). The fifth measure, cervical position, is scored only 0-2.
When cervical laceration occur during delivery, they are most common at what position?
a. 3 and 9 o'clock
b. 12 and 6 o'clock
c. 10 and 4 o'clock - (answer)A
Cervical lacerations are most often identified with vaginal retractors when bleeding is persistent after
delivery. The lacerations are sutured with absorbable sutures, so no further treatment is usually
indicated. Minor lacerations often occur during delivery, but they usually require no treatment. Tears
are more common after forceps assisted and vacuum assisted deliveries than normal vaginal births
If using fetal pulse oximetry, what is normal oxygen saturation?
a. 30% to 65%
b. 65% to 90%
c. 90% to 100% - (answer)A
because of the fetus's high hemoglobin and hematocrit. A value below 30% may be associated with
hypoxia and metabolic acidosis. For fetal pulse oximetry, which may be used to determine whether
immediate intervention is needed for non-reassuring fetal heart rate, a special single-use sensor is
placed internally along the fetal cheek, temple, or forehead. However, fetal pulse oximetry has not been
found to reduce overall rates of Caesarean.
A decrease of fetal heart rate of at least 15 bpm for at least 10 minutes is classified as
a. recurrent deceleration.
b. prolonged deceleration.
c. baseline change. - (answer)C
, RNC-OB ACTUAL Exam WITH QUESTIONS AND CORRECT VERIFIED ANSWERS GRADED A+
GUARANTEED PASS
If it persists more than 2 minutes but less than 10 minutes, it is classified as a prolonged deceleration.
Recurrent decelerations are classified as occurring with half or more of uterine contractions in a 20
minute period. Intermittent decelerations occur with fewer than half of uterine contractions in a 20
minute period.
With suspected fetal hypoxia, a cord blood gas specimen is obtained during delivery by
a. withdrawing blood from the vein/artery before the cord is clamped or cut and before placental
expulsion.
b. placing one clamp and withdrawing blood above the clamp before cutting the cord.
c. double clamping a 10 to 20 cm segment, cutting it out, and then withdrawing blood from the
segment. - (answer)C
The segment can be placed on ice temporarily as cord blood gas can be accurately assessed for 60
minutes. An arterial sample is preferred over venous, but paired sampling is recommended. A pH of 7.24
or less is associated with neurological compromise. A base excess of 12 mmol/L or more is predictive of
motor or cognitive impairment.
When eliciting the scarf sign in a neonate, the infant's elbow crosses the midline of the chest, probably
indicating a
a. preterm infant.
b. term infant.
c. postterm infant. - (answer)A
At fullterm, the elbow should not cross the midline. For the scarf test, the neonate should be placed
supine. One arm is grasped and the hand pulled toward the opposite shoulder and then the position of
the elbow is assessed in relation to the midline of the chest.
