A

Its not connected to the mom.

17
Q

What is TORCH syndrome?

A

It is caused by infections.
T-oxoplasmosis: protozoa (cate feces)
O-ther: Hep A, B virus

18
Q

20
Q

Physical changes in pregnancy?

A

Endocrine system
-increase thyroid gland activity, but does not result in hyperthyroidism
-oxytocin(posterior pituitary) increase amounts as fetus matures. Higher levels of progesterone prevent oxytocin from finding receptor sites in uterus and stimulating uterine contractions
-Prostaglandins responsible for relaxation of ligaments, soften and ripen cervix(open for labor)
-Parathyroid hormone controls Ca and Mg metabolism
-Pancreatic enzymes and insulin
-Adrenals circulating cortisol regulates CHO and Pro metabolism, increase due to estrogen hormone

21

24-48 hrs postpartum
