Correct Answer is C

Explanation

Choice A rationale

Flexion of all four extremities is a normal finding in newborns but does not specifically indicate successful transition to extrauterine life. It suggests good muscle tone, which is important, but vigorous crying is a more direct sign of effective respiratory effort and lung function.

Choice B rationale

A positive Babinski reflex is a normal reflexive response in newborns, indicating proper neurological function. However, it does not provide direct information about the newborn's respiratory or cardiovascular adaptation to life outside the womb.

Choice C rationale

Crying vigorously when stimulated is a strong indicator that the newborn is transitioning well to extrauterine life. It demonstrates that the infant's lungs are functioning properly, and they are capable of clearing airway secretions and maintaining adequate oxygenation, which are critical for survival outside the uterus.

Choice D rationale

A heart rate of 220 beats/minute is significantly higher than the normal range for newborns (120-160 beats/minute). Such tachycardia could indicate stress, dehydration, or underlying cardiac issues and does not reflect a normal transition to extrauterine life. .

A. "You may be at higher risk for having a spontaneous miscarriage.”. B. "You may have an increased chance of having preeclampsia.”. C. "This medication will have no effect on your unborn child.”. D. "You may experience postpartum hemorrhaging after delivery.”.

Correct Answer is A

Explanation

Choice A rationale

Misoprostol is a synthetic prostaglandin E1 (PGE1) analog that can induce uterine contractions, increasing the risk of a spontaneous miscarriage, particularly in early pregnancy.

Choice B rationale

Misoprostol is not known to increase the risk of preeclampsia. Preeclampsia involves high blood pressure and potential damage to other organ systems, typically appearing after 20 weeks of pregnancy.

Choice C rationale

Misoprostol does have an effect on the unborn child due to its ability to cause uterine contractions and cervical ripening, potentially leading to miscarriage.

Choice D rationale

Misoprostol is not associated with an increased risk of postpartum hemorrhaging after delivery. It is often used to manage postpartum hemorrhage by promoting uterine contractions.
