Cards

Term
Types of tubes
Definition
Orogastric (ICU only)
Nasogastric (NGT)
- Large bore (Salem Sump)
- Small bore (Corpak)
Naso-duodenum (ND)
Naso-jejunum (NJ)
Gastrostomy tube (GT)
Jejunostomy tube
Term
Purposes of gastrointestinal intubation
Definition
- Decompress stomach to remove contents
- Lavage (flush) to remove toxins/meds
- Diagnose GI disorders
- Administer meds and feedings
- Compress a bleeding site
- Aspirate gastric contents for analysis
Term
Complications of nasogastric intubation
Definition
- Aspiration or aspiration pneumonia
- Injury from insertion (performation of mucosa or lung injury from improper placement)
- Nosebleeds
- Tracheal-esophageal fistula
- Erosion or necrosis of tissue
Term
Complications of nasogastric tube feedings
Definition
- Obstruction of tube
- Perforation of tube
- Tube migration out of correct position
- Regurgitation or aspiration of feeding
- Diarrhea, N/V
- Abdominal distention, cramping, discomfort from too much feeding or too fast a rate
Term
How to check placement
Definition
- Initial placement checked by X-ray before infusion starts
- Before feeding check with aspiration of gastric contents
- Putting air in does not work
Term
What you need to know about your patient's tube
Definition
Purpose
Insertion site
Distal location
Type of tube
Amount of suction
Date of insertion
Initial placement confirmed by XR
Bedside confirmation of placement
Term
Purposes of large bore NGT (Salem Sump)
Definition
- Diagnostic: eval of gastric content
- Lavage: remove toxins, poisons
- Decompression: remove accumulated gas/contents
- Provide bowel rest in SBO
- Administer feeding/meds
Term
NGT: small bore (Corpak)
Definition
- Replace Salem Sump after 1-2 wks or inserted instead when only for feeding
- Can only be used for meds/feeding (no suction)
- Can't accurately measure residual (hold feeding if residual >200)
- Flush! gets clogged easily
Term
GT/PEG and JT
Definition
- Used for long-term feedings, comatose pts
- Inserted surgically in endoscopy lab
- Tract matures in 3-4 wks
- Nursing implications
Site care, minimize movement of tube
Feeding/med administration
Aspiration precautions
Term
When to administer enteral or parenteral nutrition
Definition
- Patient has been or will be unable to eat for 7+ days
- Severe malnourishment or unable to meet nutritional needs orally
Term
Why enteral feeding is preferred to parenteral nutrition
Definition
- Preferred when pt has functional gut
- Less expensive
- Less risk of infection
- More easily done at home or LTC
- Maintains mucosal integrity
- Doesn't require special IV access
Term
Parenteral nutrition
Definition
- When pt is on bowel rest of has malabsorption
- Supplies all necessay daily requirements
- Usually given via central line in high-flow large volume vein
- Primary complication: infection
- Change bag and tubing q24hr
- Change central line dressing with sterile technique q1wk
Term
Enteral nutrition
Definition
- Need extra hydration with it
- Usually well-tolerated (start slowly and advance to ordered rate)
- Monitor for N/V, diarrhea, abd bloating and discomfort
Term
Enteral nutrition aspiration precautions
Definition
- HOB at 45 degrees at all time
- Check placement of tube
- Check for residual, if more than 200 hold off
- Monitor respiratory status
Term
What factors determine nutritional status
Definition
- Intake of nutrients
- Absorption of nutrients
- Nutrient metabolism
- Nutrient losses

First 3 are profoundly affected by aging (hence old ppl much more likely to be malnourished)
Term
Indicators of malnutrition
Definition
- Weight loss of 5% in 30 days
- Weight loss of 10% in 6 months
- BMI <18
Term
Nutritional support
Definition
- Encourage high calorie choices
- Vitamin B12: gastric atrophy
- Calcium and vit D
- Nutrition supplement drinks btwn meals
Term
Consequences of malnutrition in hospitalized pt
Definition
- decreased immune response
- decreased wound healing= pressure ulcers
- decreased muscle mass= functional decline
- decreased cardiac and respiratory function
- depression, fatigue
- increased rate of all complications
- increased LOS
Term
Lab tests for malnutrition
Definition
Albumin
- Shows chronic/pre-existing malnutrition
Pre-albumin
- Shows acute malnutrition (2 day half life)
- Can be followed to assess effectiveness of nutritional interventions
Term
Nursing implications of malnutrition
Definition
- Monitor food intake
- Monitor how long pt is NPO and get follow up meals ASAP
- May need to handfeed older pts, they need more time to eat
- Be assertive abt getting nutrition consults earlier
Term
BMI ranges for adults
Definition
25-29.9 is overweight
30 or higher is obese
Term
Weight ranges in children (2-18 yrs)
Definition
- overweight: 85th-95th percentile for children of same age/sex
- obese: 95th and above percentile for children of same age/sex
Term
Criteria for bariatric surgery
Definition
- BMI>40 or BMI>35 w/ comorbid conditions
- failure of medically supervised weight-loss programs
- absence of uncontrolled psychotic or depressive disorders
- Absence of current alcohol or substance abuse
Term
Laparoscopic adjustable gastric band (LAGB)
Definition
Works on reducing gastric content and malabsorption
Most common procedure
Term
Laparoscopic sleeve gastrectomy (LSG)
Definition
Restrictive procedure and excision of the grehlin (hunger hormone) producing stomach provides added benefit of early satiety
Term
Roux-en-y gastric bypass (RNYGBP)
Definition
- Uses restriction and malabsorption to achieve weight loss
- Food intake limited by dividing stomach to create a 15-30ml pound connected to a loop of small intestine
Term
Nursing care post op bariatric surgery
Definition
Pain management
Wound care
Venous thromboembolism prophylaxis
Pulmonary toilet
Early and frequent ambulation
Line and drain maintenance
Fluid balance
Nutrition therapy
Continued education and emotional support
Term
Why obese pts are at higher risk for wound complications
Definition
- Poor vascularity of adipose tissue
- Increased wound tension
- Greater intra-abdominal pressure
- Frequent presence of diabetes
Term
Skin care in obese patients
Definition
- Pad skin folds
- Avoid plastic-lined underpads bc they create excessive heat and perspiration
