A 6-week-old infant with pyloric stenosis is scheduled for a pyloromyotomy. Which pre-operative nursing action has the highest priority?

Choice A reason: Determining the need for urinary catheterization is not a task that the nurse should assign to the PN, as this requires clinical judgment and critical thinking, which are beyond the scope of practice of the PN. This is a distractor choice.

Choice B reason: Titrating oxygen to prescribed parameters is a task that the nurse can assign to the PN, as this involves following orders and protocols, which are within the scope of practice of the PN. Therefore, this is the correct choice.

Choice C reason: Receiving a postoperative client and conducting the assessment is not a task that the nurse should assign to the PN, as this requires initial assessment and data collection, which are the responsibility of the registered nurse. This is another distractor choice.

Choice D reason: Evaluating and updating plans of care for clients is not a task that the nurse should assign to the PN, as this requires nursing diagnosis and outcome identification, which are part of the nursing process that only the registered nurse can perform. This is another distractor choice.

Choice A reason: 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 reason: 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 reason: 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 reason: 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.
