. 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
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
