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. -
correct 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. -
correct answer ✅C

-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. -

...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. -
correct 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

a. fractured scapula.

b. cerebral palsy.
c. fractured clavicle. -
correct 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 -
correct 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
