Answers
1. Which type of anemia is ex- Normocytic anemia due to hemodilution. max at 34 weeks
pected in pregnancy? When is
the max effect achieved?
2. Type of dyspnea seen in up Physiologic dyspnea of pregnancy
to 75% of women by the third
trimester
3. What type of acid-base dis- Compensated respiratory alkalosis
turbance is common during
pregnancy and why? Increased minute ventilation = low PCO2 = elevates pH; reten-
tion of bicarb compensates
(pH ~HCO3/PCO2)
4. Describe the normal PFT IC ,TV, Minute ventilation = increased
changes with pregnancy
FRC, ERC, RV = decreased
5. What are the 2 major changes 1. increased tidal volume and minute volume --> respiratory
driving shortness of breath in alkalosis
pregnancy? 2. Reduced FRC
6. What is one of the major risks Increased risk of pulmonary edema
of using multiple tocolytics in
a pregnant woman? (Given in isotonic fluids, further reducing plasma osmolality,
increasing pulmonary edema)
7. Up to 95% of pregnant Systolic murmur due to increased flow volume
women will have which type
of murmur? Why?
8.
, Explain the normal degree of Unequal dilation (R>L) due to cushioning provided by the
dilation of the ureters and re- sigmoid colon to the left ureter and from greater compression
nal pelvis in pregnant women of the right ureter due to dextrorotation of the uterus
9. Which vein complex is dilat- Right ovarian vein complex (it lies obliquely over the ureter)
ed in pregnancy and may con-
tribute to dilation of the right
ureter?
10. How do levels of Free T4 and Since TBG increases, total T4 increases, but Free T4 remains
total T4 change in normal relatively constant (it is not bound)
pregnancy?

portant in the management
of a patient with suspected --lungs are the MC site of metastatic disease in patients with
molar pregnancy? gestational trophoblastic disease

, 16. Valproate use in pregnancy is NTDs, hydrocephalus, and craniofacial malformations
associated with which 3 ter-
atogenic effects in the fetus?
17. What structural anomaly of Cardiac anomalies
the fetus is most likely in a
patient with poorly controlled --also NTDs
T1DM before pregnancy and
during organogenesis?
18. When is CVS typically per- 10-12 weeks gestation
formed?
19. CVS can be used to detect Since it extracts mitotically active villi...
which types of defects? 1. Fetal chromosomal abnormalities
2. Biochemical or DNA-based studies, e.g. CF
--doesn't detect NTDs or omphaloceles
20. Which test has the highest de- Cell-free DNA
tection rate and lowest false
positive rate in trisomy 21
screening?

the first-trimester combined 2. PAPP-A
test for trisomies? 3. B-hCG
