100
Leading cause of neonatal mortality in the United States.
What is preterm birth?
100
Used in the mid 20th century to "slow" pre-term labor.
What is beer (ethyl alcohol)?
100
True or false: Bedrest, hydration, and pelvic rest improve the rate of pre-term birth.
What is false.
100
Gestational age that antenatal steroids are generally administered.
What is 24-34 weeks EGA?
200
Percentage of live births before term in the United States.
What is 11.5%?
200
Calcium channel blocker that is commonly used as a tocolytic.
What is Procardia?
200
Screening for and treatment of asymptomatic bacteriuria can reduce the frequency of preterm birth or low birth weight by approximately this percentage.
What is 50%?
200
Fetal benefits to steroid administration.
What is reduced incidence and severity of neonatal respiratory distress syndrome; reduced incidence of intraventricular hemorrhage, and reduced incidence of necrotizing enterocolitis?
300
Percentage of women with presumptive pre-term labor who will not have a pre-term delivery.
What is 80%?
300
Cause myometrial relaxation by binding to β2-adrenergic receptors and subsequently increasing the levels of intracellular cyclic AMP. An increase in intracellular cyclic AMP activates protein kinase, which inactivates myosin light-chain kinase, thus diminishing myometrial contractility.
What is terbutaline?
300
Weekly administration of this agent to women with a previous preterm birth reduces the risk of recurrence by 33%.
What is 17 alpha-hydroxyprogesterone caproate?
300
Options for/dosages of antenatal steroids.
What is dexamethasone: 4 doses - 6 mg IM q12 hours Betamethasone 2 doses - 12 mg IM q24 hours?
400
When negative, this test has a more than 95% likelihood of a patient remaining undelivered for the next 2 weeks.
What is fetal fibronectin?
400
This agent hyperpolarizes the plasma membrane and inhibits myosin light-chain kinase activity by competing with intracellular calcium, which in turn reduces myometrial contractility.
What is Magnesium Sulfate?
400
Daily administration of this agent reduced by more than 40% the frequency of birth before 34 weeks of gestation among asymptomatic women with a short cervix as seen on ultrasonography.
What is vaginal progesterone?
400
ACOG has stated that a rescue course of antenatal corticosteroids can be considered if these 3 criteria are met.
What is 1) antecedent corticosteroid treatment was given more than two weeks previously, 2) the gestational age is less than 33 weeks, and 3) the patient is likely to deliver within the next seven days?
