RNC-OB CERTIFICATION PRACTICE
EXAMINATION 2026 QUESTIONS WITH
ANSWERS GRADED A+
◍ For administration of prostaglandin cervical gel, the patient should be placed
in a. left lateral Sims position b. lithotomy position c. dorsal recumbent
position.
Answer: CSome preparations are administered with a prefilled syringe
attached to a catheter, which is inserted into the endocervix, which other
preparations are placed in a diaphragm, which is then positioned against the
cervix. After insertion or application of the gel, the woman remains lying on
her back for 30-60 minutes with a small pillow or roll placed beneath her
right hip in order to tip the uterus to the left.
◍ The vibroacoustic stimulation test (VST) is sometimes used in conjunction
with a. contraction stress test (CST) b. ultrasound c. nonstress test (NST).
Answer: C...because the fetus may be nonreactive during the NST if it is in a
sleep cycle. During VST, sound and vibration are applied to the maternal
abdomen through a device that delivers 90 dB of sound for 1-3 seconds,
stimulating movement of the fetus so that the NST can be more adequately
assessed. As an alternative, the NST may be repeated at a later time when
the fetus is more active.
◍ The cervix is considered uneffaced at a. 2 cm. b. 3 cm. c. 4 cm..
Answer: CThe cervix is considered uneffaced at 4 cm (0% effacement).
Effacement refers to thinning of the cervix, with the length of the cervix
expressed in numbers of centimeters, and the degree of effacement in
percentages. Complete effacement (100%) occurs when the cervix has
completely thinned. Some patients efface slowly over the weeks prior to
labor, especially if the fetal head is in the pelvis and applying pressure to the
, cervix, but others efface after onset of labor.
◍ negative/positive CST.
Answer: - Negative‐ no late decels, stable FHR- Suspicious‐ intermittent
lates/variables- Positive‐ Late decels in over half contractions
◍ The progression of labor is based on:.
Answer: individual factors and clinical conditions
◍ ------------ IS most reliable way to hear a fetal arrhythmia.
Answer: fetoscope
◍ In fetal vibroacoustic stimulation, a reactive response is indicated by fetal.
Answer: heart rate accelerations
◍ ph: 7.31pco2: 40hco3: 20.
Answer: metabolic acidosis
◍ transition.
Answer: 8-10 cm
◍ what happens with DIC?.
Answer: widespread bleeding both internal and external- usually starts off
with bleeding episode, then clotting factors are depleted due to over
activation, then they bleed more- shock risk- massive transfusion protocol
◍ Neonatal thrombocytopenia is defined as a platelet count of a. less than
250,000/mm3b. less than 150,000/mm3c. less than 100,000/mm3.
Answer: BWhile platelet counts tend to be higher in neonates and children
up to 5 years of age (217,000/mm3 to 497,000/mm3) than in older children
and adults (150,000/mm3 to 450,000/mm3), and similar to adults in healthy
preterm infants, neonatal thrombocytopenia is defined as a platelet count
less than 150,000/mm3. Most cases (75%) of neonatal thrombocytopenia
result from impaired production of platelets, while remaining cases result
from increased destruction. Incidence of thrombocytopenia is low in well
newborns, but may affect over a third of infants in the NICU and up to three
quarters of infants who have extremely low birth weight.
,◍ normal fibrinogen.
Answer: 150-400 mg/dl
◍ cat 3 tracing.
Answer: >Key Element‐‐‐ absent variability with ANY1‐ recurrent late
decels or recurrent variable decels or bradycardia2‐ sinusoidal
◍ Medicines for HIV for birth.
Answer: Zidovudine and Nevirapine- 3 hrs prior to c/s- continuous with
labor
◍ An amniotic fluid index (AFI) of 28 cm a. indicates hydramnios
(polyhydramnios). b. indicates oligohydramnios. c. is a normal AFI..
Answer: ANormal AFI ranges from 5-25 cm. Oligohydramnios is < 5 cm.
While some pregnant patients with hydramnios may complain of difficulty
breathing, most are asymptomatic and the condition is identified on
ultrasound. It may occur with multiple gestations, maternal diabetes, and
fetal abnormalities. It increases the risk of preterm labor and birth,
premature rupture of membranes, uterine atony, abruptio placentae, prolapse
of umbilical cord, and death of the fetus.
◍ what is L and S with L/S ratio?.
Answer: L and S are types of surfactantsS remains about same throughout
butL rises= more mature lungs and alveoli remain "soapy" for O2 exchange
◍ If the partner of a patient undergoing an emergency cesarean delivery is
afraid of fainting at the sight of blood, the best information is that a. almost
no one who is afraid of fainting actually faints b. the person can leave the
room at any time if feeling faint c. the sterile drape can serve as a partition
to shield the view.
Answer: C....although in some cases the patient may want the drapes
arranged so she can observe the birth. In that case, the partner may sit facing
the patient. The partner who is attending the birth must dress in scrubs and
mask and sit on a stool near the patient's head in order to provide support
and encouragement.
, ◍ For forceps-assisted and vacuum-assisted delivery, if the leading edge of the
fetal skull is at station +2 or lower, it is classified asa. outletb. lowc.
midpelvis/midforceps.
Answer: BThe classification system for assisted delivery includes specific
criteria:-Outlet: Scalp is visible as fetal head is on perineum. Positions are
ROA, LOA, ROP, or LOP.-Low: Leading edge of fetal skull at +2 station or
lower.-Midpelvis/midforceps: Fetal head engaged and above +2 station.
◍ FFN.
Answer: 22‐35 weeks, if +, Preterm birth more likely within next 2
weeks(protein that is present for adherence of fetal membranes to the uterus)
◍ Nifedipine- Procardia.
Answer: CA Channel blocker that - DECREASES CONTRACTILITY OF
SMOOTH MUSCLES
◍ The fetal head is considered engaged at which station? a. -1 b. 0 c. +1.
Answer: B..., the level of the ischial spines. Station refers to the position of
the presenting part in relation to the ischial spines. If the presenting part is
above station zero, then the station is expressed in negative numbers with
each number referring to a centimeter (-1, -2, -3). If the presenting part is
below the ischial spines, the station is expressed in positive numbers (+1,
+2, +3).
◍ The best method to determine if maternal-infant bonding is occurring is toa.
ask the mother if she is bondingb. observe maternal-infant interactionsc. ask
the father/partner if he/she observes bonding.
Answer: BBonding is characterized by progression in the mother touching
the infant and making face-to-face eye contact as well as verbally
responding to and cuddling the infant. The mother should demonstrate
pleasure in the infant through actions or words, such as referring to the
infant by name and noting family characteristics. The mother should show
sensitivity to the needs of the infant, such as hunger.
◍ In a neonate, Klumpke paralysis is associated with injury to the a. median
