Questions And Answers| Already Graded A
Incompetent cervix - (ANSWER)Painless dilation of the cervix in absence of
uterine contractions
*the cervix is incapable of supporting the weight / pressure of growing fetus and
results in expulsion of products of conception during second trimester (usually
occurs 20 wks gestation)
Risk factors of incompetent cervix - (ANSWER)-History of cervical trauma
(previous lacerations excessive dilation surgical biopsy)
-in utero, exposure to dietthystillbrstrol (DES) (ingested by mother during
pregnancy
-Increased maternal age
-Congenital structural defects
Subjective/objective data (incompetent cervix) - (ANSWER)Subjective: increased
pelvic pressure
Objective:
-Pink stained vaginal discharge or bleeding
-possible gush of fluid
-uterine contractions with the expulsion of the fetus
Diagnostic procedure (IC) - (ANSWER)-Ultrasound showing of short cervix (less
than 20 mm in length) indicates a reduced cervical competence
-prophylactic cervical cerclage (removed 37wks of gestation)
prophylactic cervical cerclage - (ANSWER)- is the Surgical reinforcement of the
cervix with a heavy ligature that is placed on submucosally around the cervix to
strengthen it and prevent premature cervical dilation, which is removed at 37
weeks gestation

Tocolytic agents - (ANSWER)Used to stop preterm labor
Ex: terbutaline-beta agonist
*causes uterus to relax
*elevates HR (hold if HR is +120)
Magnesium sulfate - (ANSWER)Tocolytic, anticonvulsant, antihypertensive, and
CNS depressant agent that also lowers BP in preeclampsia
*ASSESS values that may indicate toxicity:
-RR (<12)
-Urinary output (<30)
-reflexes (flaccid)
Magnesium sulfate antidote - (ANSWER)Calcium gluconate
*monitor for magnesium toxicity*
Preterm labor - (ANSWER)Uterine contractions and cervical changes that occur
between 20-37 wks gestation
Preterm labor Risk factors - (ANSWER)- UTI, or vaginal infections
-multifetal pregnancy
-hydramnios (+amniotic fluid)
-Age below 17 above 35
-smoking, substance abuse
-domestic violence
-hx of multiple miscarriage or abortions
-incompetent cervix
-placenta previa or abruptivio placentae
-preterm premature rupture of membranes
-dehydration
How/why does dehydration increase uterine contractions? -
(ANSWER)Dehydration stimulates pituitary gland to release ADH and oxytocin.
Preventing dehydration prevents release of oxytocin, which stimulates uterine
contractions
