A preterm labor client at 30 weeks' gestation reported rupture of membranes 4 hours ago. This was confirmed on examination. The nurse prepares to administer IM dexamethasone. When the client asks why she is receiving the drug, the nurse replies:
To help stop your labor contractions.
To prevent an infection in your uterus.
To help mature your baby's lungs.
To decrease the pain from the contractions.
To decrease the pain from the contractions.
The Correct Answer is C
Choice A rationale
Dexamethasone does not directly stop labor contractions; instead, it is used to enhance fetal lung maturity.
Choice B rationale
Dexamethasone is not for infection prevention; antibiotics are used for that purpose in cases of premature rupture of membranes.
Choice C rationale
Dexamethasone is administered to enhance fetal lung maturity, reducing the risk of respiratory distress syndrome in preterm infants.
Choice D rationale
Dexamethasone is not used for pain relief in preterm labor; other medications are prescribed for pain management.

Correct Answer is B
Explanation
Choice A rationale
Oral rehydration therapy is not used in place of feedings for infants undergoing phototherapy for elevated bilirubin levels. It's crucial to maintain proper nutrition and hydration through regular feedings.
Choice B rationale
Rotating the baby helps ensure even exposure to the bili lights, which aids in breaking down bilirubin effectively across the baby's body.
Choice C rationale
Applying restraints is inappropriate and unnecessary. It could cause distress and is not a standard practice for phototherapy.
Choice D rationale
Administering intravenous fluids is not typically needed unless there's a risk of dehydration or other medical indications as per the doctor's orders.
Correct Answer is A
Explanation
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.
