Which client is at greatest risk for early postpartum hemorrhage (PPH)?

Choice A reason: Monitoring the newborn's blood pressure is not the most appropriate action, as it is not directly related to the signs of diaphoresis, jitteriness, and lethargy. These signs are more indicative of hypoglycemia, which is a low blood sugar level that can affect newborns, especially those who are premature, small for gestational age, or have diabetic mothers.

Choice B reason: Initiating phototherapy is not the most appropriate action, as it is used to treat hyperbilirubinemia, which is a high level of bilirubin in the blood that can cause jaundice, a yellowish discoloration of the skin and eyes. Hyperbilirubinemia does not cause diaphoresis, jitteriness, or lethargy.

Choice C reason: Obtaining blood glucose by heel stick is the most appropriate action, as it can confirm the diagnosis of hypoglycemia, which is the most likely cause of the signs of diaphoresis, jitteriness, and lethargy. The nurse should perform a heel stick using a sterile lancet and a glucose meter, and obtain a blood sample from the lateral aspect of the heel. The nurse should also provide warmth, stimulation, and feeding to the newborn, and report the blood glucose level to the provider.

Choice D reason: Placing the newborn in a radiant warmer is not the most appropriate action, as it can cause dehydration, fluid loss, and further hypoglycemia. The nurse should use a radiant warmer only if the newborn is hypothermic, which is a low body temperature that can also affect newborns. The nurse should monitor the newborn's temperature and skin color, and adjust the warmer accordingly.

Choice A reason: Obtaining a type and crossmatch is not the first action that the nurse should take, as it is a preparatory step for blood transfusion, which may or may not be needed. The nurse should first identify the cause and severity of the hypotension, and initiate immediate interventions to stop the bleeding and restore the circulation.

Choice B reason: Administering oxytocin infusion is not the first action that the nurse should take, as it is a pharmacological intervention that requires a prescription and an assessment of the uterine tone and bleeding. The nurse should first evaluate the firmness of the uterus and massage it if needed, to stimulate the contraction and retraction of the uterine muscle.

Choice C reason: Initiating oxygen therapy by nonrebreather mask is not the first action that the nurse should take, as it is a supportive intervention that aims to improve the oxygen delivery to the tissues and organs. The nurse should first address the underlying cause of the hypotension, which is most likely postpartum hemorrhage, and prevent further blood loss and shock.

Choice D reason: Evaluating the firmness of the uterus is the first action that the nurse should take, as it can help determine the source and extent of the bleeding, and guide the subsequent interventions. The nurse should palpate the fundus and check the lochia, and report any signs of uterine atony, which is the most common cause of postpartum hemorrhage.
