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
