100

5 weeks
6 weeks
7 weeks
What is naegel’s rule?
Estimating due date
From the start of last menstrual cycle, add 9 months and 7 days
Who do we send to genetic counseling?
Mom is 35 years and older
Any history of mental retardation
Any history of losing babies
Really any abnormality

13,18,21 (most common)
When should chromosomal studies be done for couples, most common class of spontaneous abortions, and most common single chromosome abnormality found in spontaneous abortions?

What is FDA risk factor category A for pregnancy and breast feeding?

Animal studies show risk but human studies show no risk
What is c risk category for pregnancy and breast feeding?
No adequate studies
What is D risk category?
Good studies have in pregnant women have shown a risk.
But the benefit may outweigh the risk in emergency situations
