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
,2|Page
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
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
