RNC-OB CERTIFICATION FINAL TEST 2026
QUESTIONS WITH CORRECT ANSWERS
GRADED A+
◍ A late preterm birth is defined by.
Answer: gestational age
◍ nursing notes for PUBS.
Answer: - watch for PTL‐‐‐‐ note if blood is from vein or artery for
acid/base analysis- RP US in one hour/bleeding and hematoma formation
◍ Iron deficiency anemia during pregnancy is usually treated with a. blood
transfusion. b. ferrous sulfate, 325 mg orally daily. c. iron dextran,
intramuscular..
Answer: BIron deficiency anemia during pregnancy, accounts for
approximately 95% of cases of anemia, is usually treated with oral ferrous
sulfate, 325 mg orally daily. Higher or more frequent doses may result in GI
upset and constipation and decreased absorption. If patients are unable to
adequately absorb oral iron, then iron dextran 100 mg every other day for
about 3 weeks may be administered IM. Transfusions are only indicated if
severe symptoms, such as dyspnea, tachycardia, dizziness, are present.
◍ what is nitrous oxide contraindicated in.
Answer: pernicious anemia (binds b12)
◍ Methadone/Subutex NAS withdrawal symptoms start.
Answer: 1-3 weeks
◍ Upon initial assessment, a newborn is found to have a portion of the spinal
cord protruding from his lower back. This is indicative of a. spina bifida b.
hypospadias c. tetralogy of Fallot.
Answer: AIs a severe neural tube defect and congenital anomaly in which
, the backbone and membranes around the spinal cord protrude through an
incomplete closing in the lower back of the newborn. Upon birth, this sac
should be closely protected from rupture or injury prior to surgery.
◍ BTL Decreases risk of __________________________ 50%.
Answer: ovarian cancer
◍ the lower the baby ph, the
_______________________________________________.
Answer: the higher the risk of fetal injury/insult
◍ - EVAPORATION heat loss.
Answer: WET BODY SURFACE AREA , AMNIOTIC FLUID- Nursing
care: keep warm and dry (may delay bath), wrapping, humidified O2
◍ monozygotic.
Answer: 1 egg/1 sperm splits same genotype= IDENTICAL
◍ Most ectopic pregnancies implant in the a. cervix b. fallopian tubes c.
abdominal cavity.
Answer: BAbout 95%, with the remaining pregnancies occurring in the
abdominal cavity, ovary, and cervix. Ectopic pregnancy may lead to
maternal death (10% of total maternal deaths) and is associated with
resultant infertility; only about 60% of women are able to conceive after
having an ectopic pregnancy, and 40% of these pregnancies result in another
ectopic pregnancy. Although it is possible to carry an ectopic pregnancy in
the abdominal cavity to term with surgical delivery, these pregnancies carry
a high risk of fetal deformity.
◍ Dinoprostone (Cervidil) is used for cervical ripening in a woman at 39
weeks gestation. After one hour, tachysystole develops but the fetal heart
rate pattern is normal. Appropriate management is to:.
Answer: remove the insert
◍ intermittent auscultation guidelines.
Answer: for uncomplicated preg:- Q15-30 min 1st stage- Q5-15 min 2nd
stagefor high risk:- Q15 min 1st stage- Q 5 min 2nd stage
,◍ During pregnancy, a patient who is receiving hemodialysis for end-stage
kidney disease should generally receive hemodialysis how often? a. 3 days a
week b. 4 days a week c. 6 days a week.
Answer: C...instead of 3 days a week that is most common in non-pregnant
patients in order to protect the fetus and because waste products from the
fetus enter the maternal circulatory system. Only up to 7% of women
receiving dialysis are able to conceive and 1:5 have spontaneous abortions,
so pregnancies are high risk. Preterm birth, usually at about 32 weeks is
common.
◍ anecdotal meds for AFE.
Answer: A-O-KAtropine, ondesteron, ketoraloac helps cause
vasoconstriction when everything so constricted
◍ when R-R intervals are long, the fetal heart rate is.
Answer: slow
◍ risks for pp depression.
Answer: RISKS: Primip, Hx PPD, Hx Depression, Hx Suicide, traumatic
deliveries
◍ S/s of hyperglycemia.
Answer: polyuria, polydipsia, polyphagia (hungry)Fatigue, blurred vision,
weight loss or gain, recurring infections especially UTI
◍ what hormone stimulates the ejection of breast milk.
Answer: oxytocin
◍ chemoreceptors.
Answer: respond to decrease in FHR (caused by baroreceptors) by trying to
increase BP and FHR- epi and norepi
◍ Fetal bradycardia with variable decelerations during uterine contractions
may indicate a. placenta previa. b. abruptio placentae. c. prolapsed cord..
Answer: CIn some cases, the cord may be seen protruding from the vagina,
especially after rupture of the membranes if the presenting part is high, or
, felt on digital exam. Immediate action is required to prevent fetal hypoxia.
The patient is placed in modified Sims' or knee chest position and the
examiner inserts fingers into the vagina to hold the presenting cord off the
cord while awaiting emergent treatment, such as a Cesarean.
◍ Diabetes and birth defects.
Answer: Can cause heart or neural tube defects - gdm does not usually lead
to birth defects, but type 1 and 2 prior to pregnancy are higher risks - hgb
A1C > 8.5% pre pregnancy = >40% chance of heart defect in baby
◍ cervical pressure causes posterior pituitary to release ________.
Answer: oxytocin
◍ The effect of prolonged use of the valsalva maneuver during second stage of
labor is.
Answer: respiratory alkalosis
◍ what returns blood to the placenta to mom's circulation to be reoxygenated.
Answer: umbilical arteries
◍ The most common complication that occurs because of excessive force on
the fetal neck during delivery isa. brachial plexus injuryb. spinal cord
injuryc. respiratory distress.
Answer: A...which is often associated with shoulder dystocia. Five degrees
of injury include:-First: Stretching of nerve fibers with recovery within a
few days-Second: Compression and swelling of the nerve with recovery
usually complete but takes longer-Third: Damage to the nerve sheath with
full recovery not possible-Fourth: Formation of a neuroma that interferes
with never regeneration-Fifth: Complete loss of nerve function because of
injury of the nerve at the spinal cord
◍ If the biophysical profile shows a score of 8 with normal amniotic fluid
volume, what is the required intervention? a. No intervention needed b.
Induction of labor c. Repeat test the same day.
Answer: AA normal BPP is 10 (score of 2 on 5 different measures). A score
of 8 with normal AFI suggests very little risk to the fetus and no
