| Flap 1 |
Flap 2 |
| Small intestine sections in which a GI tube will be placed | Duodenum, Jejunum |
| Levin tube vs. Gastric/Salem sump tube r/t Lumen | Levin has 1 lumen, Salem has 2 lumen |
| Suction r/t Levin tube | Connected to intermittent suction to prevent corosion/tearing of stomach lining |
| Suction r/t Salem sump | Low continuous suction |
| Peristalsis causes tube to pass from stomach to intestines in | 24 hours |
| Length added after xiphoid process r/t NG tube measurement | 6 inches for stomach placement, 8-10 inches for intestinal placement |
| Pt instruction r/t NG tube reaching nasopharynx | Lower head, Swallow as tube is advanced/Sip water through a straw |
| 3 methods to confirm placement r/t NG tube | Measure tube length, Visual assessment of aspirate, pH of aspirate |
| Gastric vs. Intestinal vs. Respiratory aspirate r/t pH | G:acidic 1-5, I:6 or higher, R:Alkaline 7+ |
| Liquids that can declog tubes | Cola, Cranberry juice, Mix of pancreatic enzymes |
| Tube irrigation schedule | Every 4-6 hours to maintain patency |
| Measures to relieve discomfort r/t NG tubes | Lozenges, Gum, Sucking on hard candy, Limited talking |
| Sx r/t fluid volume deficit | Dry skin/mucous membranes, Decreased urinary output, Lethargy, Increased HR |
| Measure taken b/f NG tube is removed | Flushed w/10 mL of water/NS to ensure it is free of debris and away from gastric lining |
| Amino acids vs. CHO vs. Proteins vs. Fats vs. Electrolytes r/t Osmotic effects | AA, CHO, Electrolytes:great effect, Proteins:less effect, Fats:no effect |
| Dumping syndrome | concentrated solution w/high osmolality moves water to stomach/intestines from surrounding organs/vessels |
| Manifestations r/t Dumping syndrome | Feeling of fullness, N/V, Dehydration, Hypotension, Tachycardia |
| Intermittent bolus feeding administration | Administered to stomach, Large amounts(300-400 mL) at designated intervals |
| Continuous infustion method administration | Administered to small intestine, Decreases abd distention, gastric residuals & risk of aspiration |
| Method used to wean Pt from tube feedings to oral diet | Cyclic feeding |
| Residual gastric content measurement | Measured b/f each feeding/ Every 4-8 hours during continuous feedings |
| Overall goal r/t Tube feedings | Positive nitrogen balance & weight maintenance/gain |
| NG tube flushing indications | B/f & after medication/tube feeding, 2x daily when tube is not being used |
| Medication mixing r/t Feeding formula | They are not mixed w/each other or w/feeding formulas |
| Medication administration r/t Postpyloric enteric tubes | Should be avoided |
| Open system vs. Closed system r/t Hang time | O:4-hour period at most, C:24-48 hours |
| Formula temp | Room temp, Not cold |
| Prevention methods r/t Dumping syndrome | Slow formula instillation rate, Room temp feedings, Administer continuous drip feeding |
| Upright position duration post-feeding | Maintained for at least 1 hour |
| Water administration r/t Tube feedings | During and 4-6 hours after feedings to prevent hypertonic dehydration |
