RNC OB INPATIENT OB CERTIFICATION FINAL
EXAM 2026 QUESTIONS WITH COMPLETE
SOLUTIONS GRADED A+
◉ Why is obesity a hemorrhage risk? Answer: More estrogen when
obese makes their vascular system fragile and more likely to bleed
◉ Eriksons stage of development for <18 yo deliveries Answer: ID vs
ID confusion
◉ Eriksons stage of development for >35 yo deliveries Answer:
Intimacy vs isolation
◉ Highest indication for PTD Answer: Previous PTD
Also if a pt is born preterm they are likely to have their own preterm
delivery
◉ What is antiphospholipid antibody syndrome? Answer:
Autoimmune clotting disorder
- occurs when PLT and endothelial cell membranes change causing
clotting risks
- begins the cycle of: thrombosis > perfusion to the placenta
decreases > severe pre-e, abruption, IUGR, PTD, death
,- lupus anticoagulant and anticardiolipin antibodies are the most
common cause
◉ Treatment for antiphospholid antibody syndrome Answer:
Lovenox, heparin, low dose asa
◉ Lovenox vs Heparin Answer: - Lovenox is made from heparin, is
long acting, and more predictable. Frequent INRs not as routinely
required, used until about 35 wks
- heparin is short acting and can be reversed if needed
◉ Heparin antagonist Answer: protamine sulfate
◉ Normal thing that happens to blood during pregnancy Answer:
Becomes hypercoagulable
◉ What is a common cause of recurrent miscarriage and early
severe pre-e Answer: Antiphospholipid antibody syndrome
◉ How many extra calories a day when pregnant Answer: 300 / day
during 2nd trimester or 600/day with twins
◉ How much protein do you need in pregnancy Answer: 75 g daily
,◉ Good sources of folic acid Answer: Whole grains, citrus fruits,
green vegetables
◉ Why do you need folic acid? Answer: prevent neural tube defects
◉ What does maternal lead exposure cause Answer: Neuro
problems and low IQ
◉ Weight gain parameters in pregnancy Answer: Under weight (BMI
<18) : 28-40 lbs
Normal weight: 25-35
Overweight: 15-25
Obese: 11-20
◉ Risks of being obese for labor/delivery Answer: - macrosomic
fetus > shoulder dystocia > c/s birth
- higher wound dehiscence / infection rate
- PTD, GDM, Pre-e
- longer labors and bleeding
◉ Why does diabetes cause RDS (respiratory distress syndrome)
Answer: Delayed surfactant from excess glucose
, ◉ Surfactant Answer: SOAP to open alveoli, w/o surfactant, aveoli
STICKY
◉ 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
◉ Type 1 diabetes Answer: - by age 30 dx
- insufficient insulin secretion
- first sign is often DKA
- TX: diet, exercise, NEEDS INSULIN
◉ type 2 diabetes Answer: - genetic link
- resistant to insulin action and insulin secretion
- some insulin is produced, just not enough
- tx: diet, exercise, oral meds, insulin
◉ DKA Answer: Metabolic acidosis
- Compensation details: breathing fast, bc the lungs compensate to
blow off the co2 (acid)
