Study Notes
Preventing Aspiration
- Aspiration occurs when substances other than air enter the lungs, potentially due to swallowing difficulties (dysphagia) or poor swallowing reflexes.
- Medical conditions increasing aspiration risk include stroke, acid reflux, mouth sores, and dental issues.
- Overt aspiration symptoms: sudden cough, wheezing, breathing trouble, congestion, heartburn, throat clearing, or chest discomfort.
- Silent aspiration shows no obvious symptoms.
- Diet modifications for dysphagia: thickening liquids with gels or powders.
- Liquid consistencies: mildly thick (nectar), moderately thick (honey), extremely thick (pudding).
- Verify liquid thickness by observing its flow from a tilted spoon after adding thickener.
- At-risk clients should be assessed for dysphagia and placed on NPO status if aspiration signs are noted, then the provider notified.
- Tube feedings also pose an aspiration risk, indicated by altered vital signs (decreased O2 saturation, increased heart rate, blood pressure, respiratory rate) and wheezing.
- Tube feeding aspiration prevention:
- Verify initial tube placement with X-ray.
- Check tube placement every 4 hours via gastric content pH.
- Check tube feeding tolerance every 4 hours by measuring residual volume.
- Follow facility policy for residuals greater than 250 mL.
- Maintain head of bed at 30°–45° during feeding and for 1 hour after bolus feedings.
- Tube feeding aspiration signs: difficulty or painful breathing, wheezing, productive cough, or fever of 38°C (100.4°F); stop feeding and notify provider.
Assisting with Eating and Feeding
- Healthcare teams ensure clients receive necessary eating/drinking assistance.
- Assistance ranges from food texture modification to posture adjustments.
- Goal: nutritional support and complication prevention.
- RNs assess swallowing ability before delegating feeding tasks.
- Nurses promote nutrition by aiding food choices based on diet and preferences, assessing chewing/swallowing ability, and determining support needed.
- Encourage self-feeding with assistive equipment (special utensils, plates, cups) to promote independence.
- Position clients upright (90°) in a chair or bed to prevent aspiration before meals.
- Pre-meal considerations: restroom needs, hand washing, denture placement, hearing aid use, and clutter-free surroundings.
- Cut food into bite-sized pieces and provide assistance as needed throughout the meal.
Swallowing Techniques
- Speech therapists teach swallowing techniques to reduce aspiration risk.
- Refer dysphagia/aspiration risk clients to speech therapists for evaluation.
- Chin-tuck position: client holds chin to chest while swallowing to narrow airway entrance.
- Rotation of head to affected side: directs food to strong side for clients with one-sided weakness.
- Tilting of head to strong side: pushes food down the stronger side.
- Supraglottic swallow: client holds breath while swallowing, then coughs to remove residual food.
- Mendelsohn maneuver: Client swallows, holds the peak of the swallow for 2–3 seconds, and then relaxes.
Glucose Monitoring
- Glucose, from ingested food, is the body's primary energy source.
- Blood glucose monitoring assesses glucose levels, especially for clients with diabetes.
- Testing is commonly performed at the bedside using a capillary blood sample and a glucose meter.
- Blood glucose monitoring evaluates glucose level changes and helps manage diabetes.
- Check glucose levels to track treatment progress, assess dietary effects, and monitor effects of illness/stress.
- Common testing times: before/after meals or exercise, before bed, during illness, with new medications, or when routine changes.
- Fasting blood glucose: level taken after NPO for ≥8 hours.
- Expected reference range: 70 to 110 mg/dL for non-diabetic clients.
- <140 mg/dL after eating is within normal range.
- Hypoglycemia: blood glucose <70 mg/dL.
- Treatment: consume 15 g of carbohydrates (glucose tablets/gel, 4 oz juice/soda, 1 tbsp honey, hard candy).
- Recheck glucose after 15 minutes and repeat until ≥70 mg/dL, then eat a meal or snack.
- Children need less than 15g of carbohydrates Infants (6g), toddlers (8g), and small children (10g).
Insulin
- Insulin, produced by beta cells in the pancreas, lowers blood glucose by helping cells use glucose or store it.
- Glucagon, from alpha cells (antagonist), raises blood glucose.
- Administered by injection into subcutaneous tissue.
- Dosing: Units (U), typically U-100 (100 units/mL).
- Rapid-acting: Onset 15–30 min, peak 30 min–3 hr, duration 3–5 hr.
- Regular/short-acting: Onset 30 min–1 hr, peak 2–4 hr, duration 4–12 hr.
- Intermediate-acting: Onset 1–2 hr, peak 4–12 hr, duration 14–24 hr.
- Long-acting: Onset 2–4 hr, duration up to 24 hr.
- Ultra long-acting: Onset 1 hr, peak 12 hr, duration 24-42 hr.
- Before administering, check blood glucose and have correct insulin type/dose ready.
- Avoid injecting into scars or within 2 inches of the navel; avoid bruised, tender, swollen, lumpy, or numb areas.
- Insert needle at 45° (emaciated/little subcutaneous tissue) or 90° angle (adequate subcutaneous tissue).
Gastrostomy, Nasogastric, and Nasojejunal Intubation
- Gastrostomy tube (G-tube): Delivers nutrition directly to the stomach, inserted through the abdomen.
- Used for clients unable to consume adequate nutrition.
- Placed by a surgeon, typically via percutaneous endoscopic gastrostomy (PEG), laparoscopic, or open surgery.
- Clients must be NPO for at least 8 hours before placement.
- Can provide total or supplemental nutrition.
- Nasogastric (NG) tube: Thin tube inserted through nostril, esophagus, and into the stomach.
- Used for nutrition/medication, or to remove stomach contents (via suction).
- Placed by RN/PN with competency, requires X-ray verification before use.
- Nasoduodenal tube: Inserted through nasal passage, past the stomach, into the duodenum.
- Used for long-term enteral feedings or when gastric feeding is inappropriate.
- Fluoroscopy can aid placement, X-ray confirms placement.
- Nasojejunal (NJ) tube: Thin tube inserted through nostril, stomach, and into the jejunum.
- Used for clients unable to consume enough nutrition, tolerate gastric contents, or have delayed gastric emptying.
- Allows direct delivery of food, liquids, and medications into the intestines.
- Placed by a provider using guided radiology, confirmed via X-ray.
Enteral Nutrition
- Enteral nutrition: Dietary intake via medical device (feeding tube).
- Prescribed for inadequate oral intake.
- Used for clients with swallowing impairments or dysphagia.
- Can provide total sustenance or supplement diet.
- Advantages: improved nutrition, lower infection incidence, shorter hospital stays.
- Contraindications: gastrointestinal bleeding, small/large bowel obstruction, bowel ischemia.
- Can be short- or long-term.
Parenteral Nutrition
- Parenteral nutrition: Dietary intake administered intravenously (IV).
- Prevents malnutrition by replacing missing nutrients.
- Provides proteins, fats, carbohydrates, minerals, electrolytes, and vitamins.
- Used for clients whose digestive systems cannot absorb or tolerate adequate oral intake.
- Administered into a large vein through a venous access device.
- Provider customizes nutrition based on needs and lab results (electrolytes, blood glucose, mineral levels, renal and liver function).
- Partial parenteral nutrition supplements oral intake.
- Total parenteral nutrition provides total daily nutritional needs.
