32 weeks
risk factors for preterm labor
infection prior preterm birth shortening of cervix 2nd/3rd trimester bleeding pulmonary or connective tissue disorder low BMI copper or abscorbic deficiencies tobacco or substance use
a positive nitrazine or fernning test is means what?
presence of amniotic fluid –> verify ROM
will turn blue
re preterm labor: top priority assessment for fetal safety
