The principal risk factor predictive of preterm birth is:

History of preterm birth.

Low prepregnancy weight.

Smoking during pregnancy.

Obesity.

Answer and Explanation

The Correct Answer is A

Choice A rationale

History of preterm birth is the principal risk factor for predicting preterm birth. Previous preterm births significantly increase the likelihood of subsequent preterm deliveries due to underlying etiological factors.

Choice B rationale

Low prepregnancy weight is a risk factor but not as significant as a history of preterm birth. It can contribute to complications in pregnancy but does not have the same predictive value.

Choice C rationale

Smoking during pregnancy increases the risk of preterm birth but is not the principal risk factor. It is a modifiable behavior that contributes to poor pregnancy outcomes.

Choice D rationale

Obesity can impact pregnancy outcomes but is not the principal risk factor for preterm birth. It is associated with other complications rather than directly predicting preterm delivery.

Correct Answer is D

Explanation

Choice A rationale

Checking blood sugar is important in gestational diabetes but isn't immediate priority in a triage setting compared to assessing urgent conditions that could harm the fetus or mother immediately.

Choice B rationale

Assessing vaginal blood loss post-abortion is crucial, but in the presence of ruptured membranes, fetal heart rate checks take precedence to ensure the fetus's immediate well-being.

Choice C rationale

Assessing patellar reflexes in pre-eclampsia management is significant, but immediate priority in labor and delivery triage goes to ensuring fetal safety after membrane rupture.

Choice D rationale

Checking the fetal heart rate after membrane rupture is a priority because it provides immediate information about the fetus's status and any potential complications like cord prolapse or distress.

A. Prolonged labor. B. Prolapsed cord. C. Abruptio placentae. D. Retained placenta.

Correct Answer is C

Explanation

Choice A rationale

Prolonged labor is not directly linked to drug use and does not present as an immediate complication.

Choice B rationale

Prolapsed cord is not associated with substance abuse and lacks direct connection to this scenario.

Choice C rationale

Cocaine use heightens the risk of abruptio placentae, a serious condition where the placenta detaches prematurely.

Choice D rationale

Retained placenta is a concern but less likely than abruptio placentae in the context of cocaine use.
