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 ["A","B","C","D","E"]

Explanation

Choice A rationale

Hypertensive disorders, such as preeclampsia, increase the risk of placental abruption. They can cause changes in the blood vessels of the placenta, reducing blood flow and increasing the likelihood of separation.

Choice B rationale

Uterine fibroids, which are noncancerous growths in the uterus, can interfere with the proper attachment of the placenta, raising the risk of placental abruption.

Choice C rationale

Cigarette smoking contributes to placental abruption by reducing oxygen supply to the placenta, causing placental insufficiency and increasing the risk of premature separation.

Choice D rationale

Abdominal trauma, such as from a fall or car accident, can cause mechanical disruption of the placenta, leading to abruption.

Choice E rationale

Methamphetamine use can cause vasoconstriction and hypertension, which compromise placental blood flow and increase the risk of abruption.

A. Advise the woman to apply ice packs to her breasts. B. Encourage the woman to breastfeed frequently. C. Inform the woman that she should wean immediately. D. Direct the woman to notify her pediatrician as soon as possible.

Correct Answer is B

Explanation

Choice A rationale

Applying ice packs can help reduce pain and swelling, but it is not the best intervention for a breastfeeding mother with mastitis. Ice can constrict blood vessels and may hinder milk flow, which can exacerbate the condition.

Choice B rationale

Frequent breastfeeding helps to empty the affected breast and prevent milk stasis, reducing the risk of abscess formation and promoting faster healing. The mechanical action of nursing can help clear the infection and provide relief.

Choice C rationale

Weaning immediately is not advised as it can lead to engorgement and milk stasis, worsening the infection. Continuing to breastfeed ensures the breast is regularly emptied, aiding in recovery.

Choice D rationale

While notifying the pediatrician may be necessary if the baby is affected, it does not directly address the mother's condition or provide immediate relief. Primary management focuses on treating the infection and maintaining milk flow.
