Which technique is appropriate for providing intermittent tube feeding once placement of the tube has been checked?
a. Cooling the formula
b. Lowering the head of the bed
c. Allowing the bag to empty gradually over 30 to 45 minutes
d. Adding food coloring to detect aspiration
C
Allow the bag to empty gradually over 30 to 45 minutes. Gradual emptying of tube feeding by gravity from the feeding bag reduces the risk for abdominal discomfort, vomiting, or diarrhea induced by bolus or too-rapid infusion of tube feedings. Cold formula causes gastric cramping. Place the patient in high-Fowler's position, or elevate the head of the bed at least 30 degrees to prevent aspiration. Do not add food coloring or dye to formula to assist in detecting aspiration, presumably by staining tracheobronchial secretions. This is associated with increased risk for contamination and may cause patient deaths.
