Signs and symptoms of preeclampsia with severe features include (Select all that apply):

Choice A: Go to break is not an appropriate action, as it can delay the necessary interventions and compromise the fetal well-beinG. The nurse should stay with the mother and monitor the fetal heart rate and the uterine activity continuously.

Choice B: Apply 100% non-rebreather mask is an appropriate action, as it can increase the maternal oxygenation and improve the fetal oxygen delivery. The nurse should place a mask with a reservoir bag over the mother's nose and mouth and adjust the flow rate to 10 to 15 L/min.

Choice C: Give an IV fluid bolus is an appropriate action, as it can increase the maternal blood volume and improve the uterine perfusion. The nurse should administer 500 to 1000 mL of isotonic crystalloid solution rapidly through a large-bore IV catheter.

Choice D: Reposition the mother is an appropriate action, as it can relieve the uterine or cord compression and improve the fetal circulation. The nurse should turn the mother to the left or right lateral position or place her in a knee-chest position.

Choice E: Increase the oxytocin drip is not an appropriate action, as it can increase the uterine contractions and reduce the uterine relaxation and blood flow. The nurse should decrease or stop the oxytocin infusion if it is causing tachysystole or hyperstimulation.

Choice F: Decrease or stop the oxytocin is an appropriate action, as it can decrease the uterine contractions and increase the uterine relaxation and blood flow. The nurse should decrease or stop the oxytocin infusion if it is causing tachysystole or hyperstimulation.

Choice A: Explaining to the client what is happening over the next few minutes in detail and asking for teach back from the spouse is not the first action, as it may delay the urgent intervention and increase the anxiety of the client and the spousE. The nurse should provide brief and clear information and reassurance after taking the first action.

Choice B: Placing the client in a knee-chest or Trendelenburg position and raising the presenting part off the cord with your hand is the first and most important action, as it relieves the pressure on the cord and prevents cord compression and fetal hypoxiA. The nurse should maintain this position until the delivery.

Choice C: Covering the cord with a sterile, moist saline dressing is a secondary action, as it prevents the cord from drying and reduces the risk of infection. The nurse should perform this action after taking the first action.

Choice D: Preparing the client for an emergency cesarean birth is a tertiary action, as it is the definitive treatment for cord prolapse and ensures the safety of the mother and the fetus. The nurse should perform this action after taking the first and second actions.
