Two days after surgical fixation of a fractured femur, a client suddenly reports chest pain and difficulty in breathing. The nurse suspects the client had a pulmonary embolus. Which action should the nurse take first?

Choice B reason: Reviewing the hemoglobin to determine hemorrhage is an important action, but not the first one. The nurse should first identify and correct the cause of bleeding, such as bladder distension or uterine atony, before checking for blood loss and anemia.

Choice C reason: Massaging the uterus to decrease atony is not indicated in this case, because the uterus is already firm. Massaging a firm uterus can cause overstimulation and pain.

Choice D reason: Increasing intravenous infusion is not the first action, because it may worsen bleeding by increasing blood pressure and diluting clotting factors. The nurse should first assess and manage bleeding before administering fluids or blood products as prescribed.

Choice A: Obtain a capillary glucose level. This is the first action that the nurse should do, as it can diagnose hypoglycemia, which is a low blood sugar level that can cause jitteriness and tachypnea in newborns. Hypoglycemia can be caused by maternal diabetes, prematurity, infection, or delayed feeding. The nurse should check the glucose level using a heel stick and a glucometer.

Choice B: Feed 30 mL of 10% dextrose in water. This is not the first action that the nurse should do, as it may not be appropriate for all newborns with jitteriness and tachypnea. Feeding 10% dextrose in water can raise the blood sugar level, but it may also cause rebound hypoglycemia or fluid overload. The nurse should feed only after confirming hypoglycemia and obtaining a healthcare provider's order.

Choice C: Wrap tightly in a blanket. This is not the first action that the nurse should do, as it may not address the underlying cause of jitteriness and tachypnea in newborns. Wrapping tightly in a blanket can prevent heat loss and conserve energy, but it may also impair breathing or circulation. The nurse should wrap only after ruling out other causes of jitteriness and tachypnea.

Choice D: Encourage the mother to breastfeed. This is not the first action that the nurse should do, as it may not be feasible or effective for all newborns with jitteriness and tachypnea. Breastfeeding can provide nutrition and bonding for newborns, but it may also be difficult or contraindicated for some newborns with respiratory distress or infection. The nurse should encourage breastfeeding only after assessing and stabilizing the newborn's condition.
