Comprehensive Nursing Lecture Notes – Mobility, Nutrition, and Test Strategies

Test-Taking & Classroom Strategies

  • Read ENTIRE question ➜ read ALL answer options ➜ re-read question before marking.
    • Prevents misreading key qualifiers (“least”, “first”, “best”, etc.).
  • Slow, deliberate pace is rewarded; exams are not a race.
    • First one done ≠ highest score.
  • If stuck > ≈ 2 min:
    • Apply elimination tactics to reach a 50/50 guess.
    • Choose and move on—do not dwell on previous item once submitted.
  • Avoid “call the provider” unless:
    • No other action within nursing scope can improve situation.
    • Question clearly states data collection already complete.
  • Rely on evidence-based practice, not personal anecdotes or “what happened to my cousin.”
  • “Least invasive, most effective” comes before invasive/expensive steps (e.g., position change & pulse-ox before ABG draw).
  • Visualize scenarios if you are a picture/kinesthetic learner (e.g., imagine patient actually ambulating with a walker).
  • Email etiquette mirrors test strategy: read faculty messages slowly; all needed info is usually present.

Mobility & Assistive Devices

General Safety Points
  • Stand on patient’s weak/affected side when ambulating; anticipate fall toward stronger side due to center-of-gravity shift.
  • Ensure devices sized correctly to prevent brachial-plexus & skin injuries.
Acronym Review
  • “Cane opposite affected leg” (COAL) – cane held on strong side, advances with weak leg.
  • “Walker with affected leg” (WALF) – move walker forward simultaneously with weak leg.
Crutch Fit & Gait Patterns
  • Axillary bar: ≈ 2 finger-breadths (≈ 5 cm) below axilla when standing straight.
  • Handgrip at wrist crease/elbow flexed ≈ 20–30°. Weight borne through hands, not axilla.
  • Incorrect high crutch ➜ risk to brachial plexus nerves.
  • Gait styles (visual chart referenced):
    • 2-point, 3-point, 4-point, swing-through. Pick based on weight-bearing order from PT.
  • Stairs mnemonic: “Up with the good, down with the bad.”
    • Ascend: good leg → crutches + bad leg.
    • Descend: crutches + bad leg → good leg.
Walkers, Scooters, Chairs
  • Walker moves with weak leg; lock brakes before sitting.
  • Avoid tennis-ball tips on wheeled walkers (increase slide/fall risk).
  • Many pts keep two devices (e.g., one upstairs, one in car) for convenience.

Least-Invasive / Prioritization Principle

  • Oxygenation: sit pt up, encourage pursed-lip breaths, apply pulse-ox before ABG.
  • Pain/comfort: reposition, distraction, non-pharm before opioids unless severe.
  • Assessment before implementation unless life-threatening obvious.

Nutrition & Special Diets

Daily Weights & I/O
  • Best indicator of fluid balance = daily weight (same scale, clothes, time).
Gastro-Esophageal Reflux Disease (GERD)
  • Causes: weak LES, hiatal hernia (sliding or para-esophageal).
  • Teach:
    • Small, low-fat meals; avoid late-night eating (≥ 2–3 h before bed).
    • Avoid caffeine, chocolate, carbonated drinks, peppermint, spicy food, high-fat food.
    • Weight reduction, loose clothing.
    • Sleep with HOB ↑ 6–8 in or on left side (reduces reflux but does not “empty” stomach).
  • Meds: PPIs, H2 blockers, antacids.
  • Chronic GERD ➜ risk Barrett’s esophagus ➜ esophageal CA; surveil.
  • Stomach acidity reminder: pH23pH\approx2-3; foods rarely make stomach more acidic, they just irritate esophagus.
Gallbladder Disorders (Cholelithiasis/Cholecystitis)
  • "Six F’s" risk: Female, Fat, Fertile (pregnant), Forty, Fair (Caucasian), Family history.
  • Pre-op diet: low-fat, low-spice to minimize biliary colic.
  • Post-cholecystectomy: resume diet slowly; very fatty meals may trigger diarrhea due to continuous, dilute bile drip.
Gout (Hyperuricemia)
  • Uric acid crystallizes in cooler joints (big toe, fingers).
  • Diet: low-purine—limit red meat, organ meats (liver, kidney), anchovies, alcohol (esp. beer, wine).
  • Meds: allopurinol, colchicine; encourage hydration to aid renal excretion.
Phenylketonuria (PKU)
  • Inborn error: cannot metabolize phenylalanine (an amino acid).
  • Screen at birth via heel-stick.
  • Diet lifelong: avoid high-phenylalanine proteins—milk, cheese, eggs, soy, tofu; use special medical formula; avoid aspartame (contains phenylalanine).
  • Requires vitamin/mineral supplementation for growth.
Dumping Syndrome
  • Common after partial gastrectomy or bariatric surgery.
  • Patho: Hyperosmolar chyme rapidly enters jejunum → water shifts into bowel; pancreas over-secretes insulin → post-prandial hypoglycemia, cramping, diarrhea.
  • Management:
    • Small, frequent meals high-protein, high-fat, low-carb.
    • No liquids with meals; drink between meals.
    • Lie down ~30 min after eating; avoid sugary/carb drinks.
Burn & Wound Healing Nutrition
  • ↑ calories, high-protein + vitamin C to support collagen & tissue repair.
  • Monitor albumin/pre-albumin for ongoing assessment.
IBS Diet Triggers
  • Gas-forming foods to limit: beans, cabbage, Brussels sprouts, onions, carbonated drinks.
Low-Potassium Diet
  • Needed for ACE-I or K-sparing diuretics (spironolactone) causing hyper-K.
  • Avoid high-K foods: bananas, potatoes, tomatoes, avocado, salt substitutes (most contain KCl), dried fruits.
Clear Liquid Diet Basics
  • Must be water-based & transparent at room temp.
  • Allowed: water, clear broth, apple/white grape juice, tea/coffee (no milk), gelatin, Popsicles without red/purple dye, clear sodas.
  • Not allowed: milk, orange juice with pulp, puréed soups, anything opaque.
  • Colonoscopy prep: avoid red/purple dye to prevent false GI bleed impression.

Fluid & Electrolytes Highlights

  • Edema assessment sites: ankles, sacrum, lungs for crackles.
  • Dehydration signs: skin tenting, concentrated urine.
  • Sodium & potassium inverse relationship: diuretics altering one may shift the other.

Aspiration Risk & Feeding Tubes

  • High-risk conditions: stroke, ↓ LOC, dementia, Parkinson’s, myasthenia gravis, spinal cord injury.
  • Verify NG/OG tube placement primarily by X-ray; pH check as secondary.
  • For pancreatitis: best choice is naso-jejunal (NJ) or surgically placed jejunostomy so food bypasses stomach & duodenum, reduces pancreatic stimulation.
  • Tube-feeding intolerance (distention, cramping, diarrhea): stop feed, assess, consult dietitian/MD; consider formula rate, concentration.
  • Change feeding bag/tubing every 24 h to reduce infection risk.

Pediatric & Developmental Nutrition Notes

  • Toddlers often eat less volume; monitor for vitamin deficiencies during picky stages.
  • School-age caloric needs adjust with growth spurts; education on balanced diets essential.

Miscellaneous Classroom / Policy Reminders

  • Boot-camp review sessions available (topics & schedule posted; e.g., nutrition next week).
  • During exams: no food, gum, or opaque bottles; only fully clear water bottles without labels.
  • Temperature disputes in classroom: bring layers instead of adjusting thermostat excessively—maintain patient-like environment.
