A nurse is caring for a newborn immediately following delivery. Which of the following actions should be the nurse's priority in the resuscitation of this neonate?

Choice A reason: This is not the correct finding because it indicates a possible uterine rupture, which is a complication of placental abruption, not placenta previA. Placental abruption is the premature separation of the placenta from the uterine wall, which can cause severe pain, bleeding, and fetal distress.

Choice B reason: This is the correct finding because it indicates a possible placenta previa, which is the implantation of the placenta over or near the cervical os. Placenta previa can cause painless bleeding that increases as the cervix dilates and effaces.

Choice C reason: This is not the correct finding because it indicates a possible onset of labor, which is not a complication of placenta previA. Labor can cause contractions, bloody show, and cervical changes, but it does not cause excessive bleeding or pain.

Choice D reason: This is not the correct finding because it indicates a possible marginal placenta previa, which is a less severe form of placenta previa that does not cover the cervical os. Marginal placenta previa can cause mild bleeding and pain, but it is not as dangerous as a complete or partial placenta previA.

Choice A: Administering saline drops into the newborn's nares is not the first action, as it can cause aspiration and irritation of the nasal mucosA. The nurse should clear the airway of the newborn before administering any medication or fluiD.

Choice B: Suctioning the newborn's mouth first and then the nose with a bulb syringe is the first and most important action, as it can remove the excess mucus and prevent obstruction and aspiration of the airway. The nurse should squeeze the bulb syringe before inserting it into the mouth or nose and release it gently to create suction. The nurse should suction the mouth before the nose to avoid pushing the mucus back into the throat.

Choice C: Placing the newborn in Trendelenburg position is not an appropriate action, as it can cause the mucus to flow back into the throat and lungs and increase the risk of aspiration and infection. The nurse should keep the newborn's head slightly lower than the chest to facilitate the drainage of the mucus.

Choice D: Performing deep suctioning of the newborn's trachea with an endotracheal tube is not an appropriate action, as it can cause trauma and inflammation of the trachea and vocal cords and increase the risk of bleeding and infection. The nurse should only perform this action if the newborn has signs of respiratory distress or meconium aspiration and under the supervision of a provider.
