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 C reason: This is the correct answer because repositioning the infant every 2 hours is an essential 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 rotate the infant's position every 2 hours to expose different areas of the skin to the light and prevent pressure ulcers or skin breakdown.

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 reason: This is a correct answer because flushing the tube with more water is important to prevent clogging and maintain hydration. The novice should flush the tube with at least 15 mL of water before and after each medication, and between medications if more than one is given.

Choice B reason: This is a correct answer because administering each medication separately is important to prevent interactions and ensure accurate dosing. The novice should not mix different medications in one syringe or container, but give them one at a time, followed by water flushes.

Choice C reason: This is not a correct answer because adding the liquid volumes when documenting fluid intake is not necessary. The liquid medications do not count as fluid intake, but as medication administration. The novice should document the type, dose, route, and time of each medication given, as well as any adverse effects or complications.

Choice D reason: This is a correct answer because confirming that the novice determined the amount of gastric residual is important to assess tolerance and prevent aspiration. The novice should aspirate the gastric contents with a syringe before giving any medication or feeding, and measure and document the volume. If the volume is more than 100 mL or the prescribed amount, the novice should hold the medication or feeding and notify the healthcare provider.

Choice E reason: This is not a correct answer because advising the novice to use the plunger when giving medications is not recommended. The novice should use gravity to deliver the medications through the tube, by holding the syringe upright and allowing the liquid to flow slowly. Using the plunger can cause too much pressure and damage the tube or cause discomfort to the client.
