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: Feeding the infant every 4 hours is not a specific instruction for home phototherapy, which is a treatment that uses blue light to break down excess bilirubin in the skin and blood. However, feeding the infant frequently is important to promote hydration and elimination of bilirubin through urine and stool.

Choice B reason: Performing diaper changes under the light is not a recommended instruction for home phototherapy, which is a treatment that uses blue light to break down excess bilirubin in the skin and blood. The nurse should instruct the parents to turn off the light and cover the infant's eyes with protective goggles or patches during diaper changes to prevent eye damage or irritation.

Choice D reason: Covering with a receiving blanket is not an appropriate instruction for home phototherapy, which is a treatment that uses blue light to break down excess bilirubin in the skin and blood. The nurse should instruct the parents to keep the infant unclothed except for a diaper and eye protection during phototherapy to maximize skin exposure to the light and increase its effectiveness.

Choice A: Encourage rest until the analgesic becomes effective. This is not the best intervention, as it does not address the client's preference or comfort level. The analgesic may take some time to relieve the pain, and forcing the client to lie down may increase the pressure on the pancreas and worsen the pain.

Choice B: Raise head of bed until at a 90 degree angle. This is not the best intervention, as it does not address the client's preference or comfort level. Raising the head of bed may help reduce abdominal distension and improve breathing, but it may not relieve the pain as much as leaning forward.

Choice C: Place bed in a reverse Trendelenburg position. This is not the best intervention, as it does not address the client's preference or comfort level. Placing the bed in a reverse Trendelenburg position may help shift the abdominal organs away from the pancreas and reduce inflammation, but it may not relieve the pain as much as leaning forward.

Choice D: Position bedside table so the client can lean across it. This is the best intervention, as it addresses the client's preference and comfort level. Leaning forward may help decrease the tension on the pancreas and relieve the pain. The bedside table can provide support and stability for the client while sitting up.
