Nursing Diagnosis
30 min. rest period before eating.
Upright, seated position in a chair or raise the HOB to 90 degrees.
Have flex their head slightly to a chin-down position.
Unilateral weakness? Have them place food on stronger side of mouth.
Use appropriate consistency of foods and liquids.
Feed slowly, with smaller-size bites.
Let them chew thoroughly and swallow before taking another bite.
Match the feeding speed with their readiness.
Assess chewing/swallowing throughout meal (inspect mouth for food).
If coughing or choking, remove the food immediately.
Have oral suction equipment available at the bedside, if needed.
Aspiration Prevention: Oral Feedings
Nutrients provided intravenously
Peripheral or central line
Initiating parenteral nutrition
Preventing complications
Parenteral Nutrition
Verify that the appropriate ENFit connector is attached to the enteral tube when administering tube feedings.
Use aseptic technique when preparing and delivering enteral feedings.
Label enteral equipment with patient name and room number; formula name, rate, and date and time of initiation; and nurse initials.
Practice “right patient, right formula, right tube, right ENFit adapter.”
Safety Guidelines for EN/PN Feedings(1 of 2)
Position the patient upright or elevate the head of the bed a minimum of 30 (preferably 45) degrees during tube feedings & 1 hr. afterward to prevent reflux & aspiration.
Pause tube feeding if repositioning or lying flat (prevent aspiration).
Trace all lines and tubing back to the patient to ensure only enteral-to-enteral connections.
Do not add food coloring or dye to EN.
Refer to manufacturer guidelines to determine hang time.
Always use an infusion pump for continuous enteral feedings and PN.
Safety Guidelines for EN/PN Feedings(2 of 2)

Clear broth, tea, clear soda, juices without pulp, popsicles, and gelatin
Preoperative or postoperative, gastrointestinal problems, or before some diagnostic testing
