A nurse is caring for a client who is receiving continuous enteral nutrition and is experiencing diarrhea. Which of the following actions should the nurse take?

Choice A reason: Dyspnea is a sign of pulmonary edema, which can occur as a complication of parenteral nutrition due to fluid overload or allergic reaction¹². The nurse should monitor the client's respiratory status and oxygen saturation and report any signs of respiratory distress.

Choice B reason: Parenteral nutrition should not be infused by gravity, as this can cause fluctuations in the infusion rate and lead to hyperglycemia or hypoglycemia¹³. The nurse should use an infusion pump to deliver parenteral nutrition at a constant and controlled rate.

Choice C reason: Parenteral nutrition solution should be administered within 30 min after removing from the refrigerator, as prolonged exposure to room temperature can increase the risk of bacterial contamination and infection¹⁴. The nurse should check the expiration date and inspect the solution for any discoloration, cloudiness, or particulate matter before administration.

Choice D reason: Parenteral nutrition bag and infusion tubing should be changed every 24 hr, not every 72 hr, to prevent the growth of microorganisms and reduce the risk of infection¹⁵. The nurse should use aseptic technique when changing the bag and tubing and follow the facility's protocol for dressing changes and catheter care.

Choice E reason: Parenteral nutrition should be started only after the central venous catheter position is confirmed by radiology, as incorrect placement can cause serious complications such as pneumothorax, hemothorax, or cardiac tamponade¹⁶. The nurse should obtain a chest x-ray and wait for the provider's confirmation before initiating parenteral nutrition.

Choice A reason: A low-protein diet is essential for clients who have PKU, as they cannot metabolize the amino acid phenylalanine. High levels of phenylalanine can cause intellectual disability and other neurological problems. A low-protein diet should be started before pregnancy and maintained throughout pregnancy to prevent fetal harm.

Choice B reason: Serum bilirubin is not related to PKU. It is a product of red blood cell breakdown and is elevated in conditions such as jaundice, liver disease, or hemolytic anemia. It does not need to be monitored routinely in clients who have PKU.

Choice C reason: Diet sodas are not recommended for clients who have PKU, as they often contain artificial sweeteners such as aspartame, which is a source of phenylalanine. Diet sodas should be avoided completely or consumed very sparingly by clients who have PKU.

Choice D reason: Breastfeeding will not prevent the baby from developing PKU, as PKU is a genetic disorder that is inherited from both parents. If both parents have PKU, the baby will have a 100% chance of having PKU. If one parent has PKU and the other is a carrier, the baby will have a 50% chance of having PKU. If one parent has PKU and the other is not a carrier, the baby will not have PKU but will be a carrier. Breastfeeding may provide some benefits for the baby, such as immunity and bonding, but it will not affect the baby's PKU status.
