A nurse is administering a unit of RBC 350 mL over 3 hr to a client who has anemia. The nurse should set the IV pump to deliver how many mL/hr?

(Round the answer to the nearest whole number)

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.

Choice A reason: To call for an immediate magnesium sulfate level is not the immediate action that the nurse should take, as it is a diagnostic test that requires a blood sample and a laboratory analysis, which can take time and delay the treatment. The nurse should first stop the infusion and notify the provider, as the client is showing signs of magnesium sulfate toxicity, which is a life-threatening condition that can cause respiratory depression, cardiac arrest, or coma.

Choice B reason: To prepare to administer hydralazine is not the immediate action that the nurse should take, as it is a pharmacological intervention that requires a prescription and an assessment of the blood pressure and the fetal status. Hydralazine is an antihypertensive drug that lowers the blood pressure and prevents the complications of severe preeclampsia, such as eclampsia, stroke, or organ damage. However, the client's blood pressure is not very high and is not the main problem at the moment.

Choice C reason: To discontinue the magnesium sulfate infusion is the immediate action that the nurse should take, as it is the first and most important intervention that can reverse the effects of magnesium sulfate and restore the neuromuscular function and the respiratory rate. Magnesium sulfate is a drug that prevents seizures and lowers the blood pressure in clients with severe preeclampsia, but it can also cause toxicity if the dose is too high or the infusion is too fast.

Choice D reason: To administer oxygen is not the immediate action that the nurse should take, as it is a supportive intervention that improves the oxygen delivery to the tissues and organs, but does not address the underlying cause of the respiratory depression, which is the magnesium sulfate toxicity. The nurse should administer oxygen only after stopping the infusion and assessing the oxygen saturation and the respiratory status.
