Final answer:
The major complications of initiating parenteral feedings in a patient who cannot have enteral tube feedings include sepsis and fluid and electrolyte imbalances.
Step-by-step explanation:
Initiating parenteral feedings in a patient who cannot have enteral tube feedings can lead to several major complications. The correct option is
Sepsis and fluid and electrolyte imbalances.
Parenteral feedings bypass the digestive system and deliver nutrients directly into the bloodstream. Sepsis, which is a severe infection, can occur due to the introduction of bacteria during the administration of parenteral nutrition. Fluid and electrolyte imbalances can also result from the parenteral nutrition formula, which may not adequately match the patient's specific needs.
