The principal risk factor predictive of preterm birth is:
History of preterm birth.
Low prepregnancy weight.
Smoking during pregnancy.
Obesity.
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 B
Explanation
Choice A rationale
Checking for ketones in urine is related to metabolic conditions like diabetic ketoacidosis, not directly relevant to the immediate care of an eclamptic client.
Choice B rationale
Padding the bed rails and headboard helps prevent injury during seizures, which is crucial in managing a client with eclampsia.
Choice C rationale
Providing visual and auditory stimulation can increase the risk of further seizures in an eclamptic client. Reducing stimulation is usually recommended.
Choice D rationale
Placing the bed in the high Fowler's position is not appropriate for managing a client post-seizure. The priority is ensuring airway patency and preventing injury.
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.
