A nurse is caring for a client who is 5 hr postpartum following a vaginal birth of a newborn weighing 11 lb 6 oz. (5160 g). The nurse should recognize that this client is at risk for which of the following postpartum complications?

Choice A reason: Increased risk of anemia is not a likely cause of respiratory distress in a term macrosomic newborn, as it can affect any newborn regardless of the maternal diabetes status or the fetal size. Anemia can cause pallor, tachycardia, and poor feeding, but not respiratory distress.

Choice B reason: Hyperinsulinemia is a likely cause of respiratory distress in a term macrosomic newborn, as it results from the fetal exposure to high maternal glucose levels and the subsequent overproduction of insulin. Hyperinsulinemia can impair the synthesis of surfactant, which is a substance that prevents the alveoli from collapsing and facilitates gas exchange. Hyperinsulinemia can also cause hypoglycemia, which can affect the respiratory center and cause apnea.

Choice C reason: Increased blood viscosity is not a likely cause of respiratory distress in a term macrosomic newborn, as it can affect any newborn with polycythemia, which is an abnormally high number of red blood cells. Polycythemia can cause cyanosis, jaundice, and thrombosis, but not respiratory distress.

Choice D reason: Brachial plexus injury is not a likely cause of respiratory distress in a term macrosomic newborn, as it affects the nerves that supply the arm and hand, not the lungs. Brachial plexus injury can occur due to the excessive traction or stretching of the shoulder during delivery, and can cause weakness, paralysis, or sensory loss in the affected arm.

Choice A reason: This client should be seen first, as she has the most urgent and acute problem that requires immediate assessment and intervention. Severe pain after a cesarean birth can indicate infection, hemorrhage, or wound dehiscence, which are serious complications that can affect the client's recovery and well-being. The nurse should evaluate the client's pain level, location, and characteristics, and administer analgesics as prescribed. The nurse should also inspect the incision site, monitor the vital signs and lochia, and provide comfort measures.

Choice B reason: This client should be seen second, as she has a chronic and stable problem that requires ongoing monitoring and management. Preeclampsia is a hypertensive disorder of pregnancy that can cause complications, such as eclampsia, HELLP syndrome, or placental abruption. However, this client has a mild elevation of blood pressure that does not indicate severe preeclampsia or imminent eclampsia. The nurse should check the client's urine protein, reflexes, and edema, and report any signs of worsening condition to the provider.

Choice C reason: This client should be seen third, as she has a normal and expected outcome that requires routine education and discharge planning. A vaginal delivery without complications does not pose any significant risk or concern for the client or the newborn. The nurse should review the discharge instructions, such as follow-up appointments, self-care, breastfeeding, and warning signs, and answer any questions that the client may have.

Choice D reason: This client should be seen last, as she has a common and benign finding that requires reassurance and documentation. A scant amount of lochia after a vaginal birth is normal and expected, as it reflects the healing and involution of the uterus. The nurse should assess the color, odor, and consistency of the lochia, and provide perineal care and hygiene education to the client.
