Study Notes

Body Mass Index (BMI)

BMI categorizes individuals by weight ranges (underweight, overweight, obese) linked to health risks.
It guides treatment plans, like nutritional interventions or weight management programs.
Limitations: Doesn't consider muscle mass and may not be accurate for all populations (athletes, elderly).
Calculation: Weight (kg) / Height² (m²).
Healthy BMI range: 18.5–24.9 kg/m².
Overweight range: 25–29.9 kg/m².
Underweight range: < 18.5 kg/m².
Relevance in specific situations:
- Very-low-calorie diets: Recommended for BMI >30 or 27-30 with medical conditions needing weight loss.
- Pregnancy: Adequate weight gain is crucial, with different guidelines for underweight/normal vs. overweight/obese women.

Evaluating Hospitalized Patient Weight

Baseline weight on admission is essential.
Daily weight tracking monitors fluid retention (e.g., heart failure).
Standardized methods (same time, clothing) are crucial for accurate comparisons.
Significant changes may indicate malnutrition, fluid shifts, or underlying diseases.
Nurse's role:
- Underweight patients: Monitor nutritional status, consider feeding support.
- Overweight/obese patients: Monitor for complications and encourage weight management.
Weight categories and associated concerns:
- Underweight (BMI < 18.5): Malnutrition, weak immune system.
- Normal weight (BMI 18.5–24.9): Healthy range.
- Overweight (BMI 25–29.9): Associated risks like heart disease and diabetes.
- Obesity (BMI ≥ 30): Increased risk for serious health issues.

Diabetes Type 1 and Type 2

Type 1: Autoimmune destruction of pancreatic beta cells, requiring insulin therapy.
- Nutritional focus: Consistent carbohydrate intake and blood glucose monitoring.
Type 2: Insulin resistance and beta-cell dysfunction, managed with lifestyle changes, medications, potentially insulin.
- Nutritional focus: Weight management, glycemic control, and reduced cardiovascular risk.
Lifespan considerations:
- Pregnancy: Impacts eating patterns and dietary needs.
- Associated diseases: Higher risk of cardiovascular diseases.
Blood sugar levels:
- Fasting blood sugar: Normal (< 100 mg/dL), prediabetes (100–116 mg/dL), diabetes (≥ 126 mg/dL).
- Blood sugar after eating (2 hours post-meal): Normal (< 140 mg/dL), diabetes (≥ 200 mg/dL).

Screening for Malnutrition

Malnutrition is an imbalance in nutrient or energy intake (under or overnutrition).
Importance: Early identification prevents complications (delayed wound healing, infection risks).
Tools: Malnutrition Universal Screening Tool (MUST), Nutrition Risk Screening (NRS-2002).
Parameters: Weight changes, dietary intake, illness severity, BMI, and laboratory markers (albumin).
Example: An obese person with excessive calorie intake is malnourished due to the imbalance between intake and output.
Normal Values:
- Serum Proteins: 6.0–8.3 g/dL
- Hemoglobin A1C: < 5.7%
- Thyroid Levels (TSH): 0.4–4.0 mIU/L
- Serum Albumin: 3.5–5.0 g/dL

Lactose Intolerance

Reduced lactase enzyme production in the small intestine.
Symptoms: Gastrointestinal discomfort after dairy consumption.
Dietary management: Lactose-free alternatives (almond, soy, oat milk), lactase supplements.
Potential age-related development of intolerance.

Inflammatory Bowel Disease (IBD)

Two types:
- Ulcerative Colitis: Colon/rectum affecting only the mucosa.
- Crohn's Disease: Can affect any GI tract section, all intestinal wall layers.
Dietary approaches: High-calorie, low-residue diets during active disease, avoid trigger foods (e.g., dairy, high fiber). Enteral nutrition for severe cases.
Impact on nutrition: Malabsorption and increased nutrient loss require close nutrition monitoring.
Kidney stones: IBD patients should be aware of the risk due to dehydration and nutrient imbalances.

Chemotherapy Patients

Nutritional challenges: Loss of appetite, altered taste, nausea, vomiting, diarrhea, mucositis, hair loss, immunosuppression.
Can impair folate absorption, and disrupt folate metabolism.
Strategies: Nutrient-dense snacks, small, frequent meals, avoid strong odors if nausea is present.

Enteral Nutrition (EN)

Delivery of nutrients to the GI tract when oral intake is inappropriate. Used in patients with functional GI tracts.
Indications: Dysphagia, severe malnutrition, neurological impairments, critical illness.
Methods: Nasogastric tube (NGT), nasoduodenal/nasojejunal tubes, gastrostomy/jejunostomy tubes.
Monitoring: Ensure proper tube placement, tolerance, and prevent aspiration.
Benefits: Preserves gut function, fewer complications than parenteral nutrition (PN), cost-effective, mimics normal digestion.

Multiple Sclerosis (MS)

Chronic illness affecting the central nervous system (CNS). Immune system mistakenly attacks nerve fiber coverings.
Impact on nutrition: Symptoms (fatigue, swallowing difficulty) can hinder intake.
Recommendations: Anti-inflammatory diet, vitamin D, omega-3s.
Symptoms: Fatigue, numbness, vision issues, motor problems, bladder dysfunction.
Risk factors: More common in women and Caucasians, onset typically between ages 20-40.

Cancer

Nutritional goals: Support immune function, manage treatment side effects.
Key nutrients: Protein, omega-3s, antioxidants
Risk factors: Cigarette smoking, infections, radiation, immunosuppressive drugs. Suspected: Alcohol, physical activity, obesity, diabetes and environmental exposures.
Cell characteristics: Uncontrolled reproduction, abnormal nuclei, rapid mitosis.

Gestational Diabetes

Implications: Increased risk of preeclampsia, macrosomia, type 2 diabetes later in life.
Management: Balanced meals, low glycemic index foods, physical activity.
Prevalence: Higher in some minority groups.
Risk factors: Age ≥35, family history.

Dysphagia

Difficulty swallowing at any point in the process.
Symptoms: Difficulty with solids/liquids, pain, choking, sensation of food sticking.
Risks: Aspiration pneumonia, malnutrition.
Dietary modifications: Thickened liquids, pureed foods, supervised eating.
Different Dysphagia Diet Levels: Pureed, mechanically altered, advanced soft.

Nutrition for Baby, Infant, Toddler

Infants (0-12 months): Exclusive breastfeeding/formula, introduce iron-fortified cereals after 6 months.
Toddlers (1-3 years): Balanced diet with nutrient-dense foods, portion control, encourage self-feeding, variety.
Key nutrients and considerations for infants:
- Fat: Critical for brain development, provided by breast milk.
- Protein: Adequate, but not excessive to avoid kidney strain.
- Vitamins: Iron, vitamin D (supplement for breastfed), fluoride, vitamin K (at birth).
Breastfeeding: Beneficial for the first four to six months for optimal nutrition and immune support.

Anorexia

Eating disorder with intense fear of weight gain, distorted body image, self-imposed starvation, and extreme focus on food, dieting, body shape.
Interventions: Psychosocial support, caloric supplementation, monitoring.
Associated health issues: Amenorrhea, low bone density.

Omega-3 Fatty Acids

Sources: Fatty fish (salmon, mackerel), walnuts, chia seeds.
Benefits: Cardiovascular health, reduced inflammation, brain function.
Important note for omega-3 consumption: These are beneficial for minimizing risks of heart disease by reducing clotting. minimal effect on cholesterol but significant impact. Reduces heart attacks and sudden arrhythmic death.

Burns

Impact: Extensive tissue damage, hypermetabolism, muscle wasting, nutritional challenges.
Types: First-degree (sunburn), second-degree (extends to dermis), third-degree (extends to all skin layers), fourth-degree (extends to muscles/bones).
Dietary considerations: Increased energy; high protein, vitamin C, A, Zinc.

Myocardial Infarction (MI) and Cardiovascular Disease (CVD)

MI: Blood flow blockage to the heart, causing heart muscle damage.
Nutrition focus: DASH diet, omega-3s, small frequent meals, whole grains.
MI and CVD lifestyle modifications are also strongly recommended due to the high prevalence, which include: frequent exercise, smoking cessation, weight management and alcohol reduction.
CVD: encompasses conditions like coronary artery disease, hypertension, and heart failure—also a top cause of death in the US.
Preventative dietary focus: emphasizes plant-based foods, fiber, antioxidants, managing sodium, and incorporating potassium.

Kidney Stones

Two types:
- Calcium Oxalate Stones: Limit high-oxalate foods (spinach), ensure adequate calcium.
- Uric Acid Stones: Low-purine diet, avoid red meat, organ meats, shellfish, alcohol.
Risk factors: Low urine volume, obesity, dehydration, high-protein diets, history of renal stones.
Recommendations: Drink plenty of water, limit sodium, and balance calcium/oxalate intake.

Hypertension (High Blood Pressure)

Definition: High force of blood against artery walls.
Diet: Low-sodium, DASH diet.
Lifestyle choices: Regular exercise, weight management, reduced alcohol.
Types: Primary (essential), secondary (caused by underlying conditions).
Risk factors: Age, family history, poor diet, inactivity, smoking, obesity, stress.
Diagnosis: Blood pressure ≥130/80 mm Hg
Stages: (Normal, Prehypertension, Stage 1, Stage 2).
