A nurse is caring for a client who is in labor at 40 weeks of gestation and reports that she has saturated two perineal pads with blood in the past 30 min. The nurse caring for her suspects placenta previa. Which of the following is an appropriate nursing action?

Choice A reason: Misoprostol is not the first line medication for postpartum hemorrhage, as it is a prostaglandin E1 analog that causes uterine contractions and cervical ripening. Misoprostol is used for the prevention and treatment of postpartum hemorrhage, but it is less effective and more side effects than oxytocin, which is the first line medication.

Choice B reason: Pitocin is the first line medication for postpartum hemorrhage, as it is a synthetic form of oxytocin, which is a hormone that stimulates uterine contractions and retraction. Pitocin is used for the induction and augmentation of labor, and the prevention and treatment of postpartum hemorrhage, as it reduces blood loss and enhances hemostasis.

Choice C reason: Hemabate is not the first line medication for postpartum hemorrhage, as it is a prostaglandin F2 alpha analog that causes uterine contractions and vasoconstriction. Hemabate is used for the treatment of postpartum hemorrhage, but it is contraindicated in clients with asthma, hypertension, or cardiac disease, as it can cause bronchospasm, hypertension, or cardiac arrhythmias.

Choice D reason: Methergine is not the first line medication for postpartum hemorrhage, as it is an ergot alkaloid that causes sustained uterine contractions and vasoconstriction. Methergine is used for the treatment of postpartum hemorrhage, but it is contraindicated in clients with hypertension, preeclampsia, or cardiac disease, as it can cause severe hypertension, cerebrovascular accidents, or myocardial infarction.

Choice A reason: Placing the newborn in Trendelenburg position is not an appropriate nursing action, as it can cause increased intracranial pressure, decreased lung expansion, and aspiration. The nurse should position the newborn in a neutral or slightly elevated head position, with the neck slightly extended.

Choice B reason: Maintaining oxygen saturations between 93% to 95% is an appropriate nursing action, as it ensures adequate oxygen delivery to the tissues and organs, while avoiding hyperoxia or hypoxia, which can cause complications, such as retinopathy of prematurity, intraventricular hemorrhage, or necrotizing enterocolitis.

Choice C reason: Inserting an orogastric tube for decompression of the stomach is not an appropriate nursing action, as it is not indicated for oxygen hood therapy, unless the newborn has abdominal distension, vomiting, or feeding intolerance. The nurse should monitor the newborn's abdominal girth, bowel sounds, and feeding tolerance, and report any signs of gastrointestinal dysfunction.

Choice D reason: Removing the hood every hour for 10 min to facilitate bonding is not an appropriate nursing action, as it can cause fluctuations in the oxygen concentration and temperature, and increase the risk of infection. The nurse should maintain the hood in place, and encourage the parents to touch, talk, and sing to the newborn, and provide skin-to-skin contact when possible.
