GUIDE 2026 QUESTIONS WITH COMPLETE
SOLUTIONS
◉ 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 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
