Chapter 32: Diet Therapy and Special Diet

SLIDE 1 — INTRODUCTION TO MED-SURG 1

DAY 3
DIET THERAPY AND SPECIAL DIET**

🔑 What this slide means:

  • Today’s topic = Diet Therapy & Special Diets

  • This is part of medical treatment, not just comfort food

  • Food choices are ordered like medications

✅ Simple example:

  • A diabetic patient does NOT just eat regular food

  • A kidney patient cannot eat high potassium foods

✅ Memory Tip:
👉 Food = Treatment

✅ SLIDE 2 — Chapter 32: Diet Therapy and Special Diets

🔑 What this slide tells you:

  • All this content comes from Rosdahl Chapter 32

  • This chapter covers:

    • Special diets

    • Feeding assistance

    • Tube feedings

    • IV nutrition

    • Food & medication interactions

✅ Exam Tip:
If the question says “According to Chapter 32” → it’s talking about diet therapy

✅ SLIDE 3 — Introduction

🔑 Key Points (IN SIMPLE WORDS):

  • ✅ Nutrition is a vital part of therapy

  • ✅ Some illnesses require special diets

  • ✅ Sick patients may need help meeting nutrition needs

  • ✅ Mealtime is the best time for diet teaching

✅ Examples:

  • Diabetic → carb-controlled diet

  • Stroke → thickened liquids

  • Surgery → high-protein diet

  • Elderly → may need help feeding

✅ NCLEX Tip:
Patient education about food = nursing responsibility

✅ SLIDE 4 — Helping the Client Meet Nutritional Needs

🔑 Key Points:

  • Eating should be pleasant

  • Sick or stressed people may:

    • Want childhood comfort foods

    • Eat less

  • Nurses help with nutrition in:

    • Hospitals

    • Nursing homes

    • Home care

✅ Examples:

  • A sick adult only wants soup → normal

  • A home health client cannot cook → nurse ensures food access

✅ Test Tip:
Comfort improves appetite → appetite improves healing

✅ SLIDE 5 — Serving Food #1

🔑 What the Nurse MUST Do:

  • ✅ Match diet order + ID band

  • ✅ Serve self-feeding patients first

  • ✅ Keep portions small

  • ✅ Hot food hot, cold food cold

  • ✅ Fill cups ¾ full

  • ✅ Food must match special diet

  • ✅ Remove broken utensils

  • ✅ Be pleasant

✅ Examples:

  • Diabetic tray → NO regular soda

  • Dysphagia patient → NO solid food

  • Weak patient → serve last so food stays hot

✅ NCLEX Favorite Rule:
👉 Always verify DIET + ID first

✅ SLIDE 6 — Serving Food #2

🔑 Eating Environment:

  • Hospital → follow facility system

  • Nursing home → dining room

  • Home care → relaxed setting

🔑 Preparing the Client:

  • Sit them up

  • Wash hands

  • Clear clutter

🔑 During the Meal:

  • Food should look appetizing

  • Encourage self-feeding

  • Document intake

✅ Examples:

  • Bed patient → raise head of bed before eating

  • Confused patient → gentle reminders to eat

  • Weak patient → encourage independence before helping

✅ NCLEX Rule:
👉 Promote independence FIRST, assist only if needed

SLIDE 7 — Serving Food #3

Providing Between-Meal Supplements and Snacks

🔑 Key Points:

  • Given to clients with:

    • High nutritional needs

    • Poor appetite

  • May be ordered by the healthcare provider

  • Must be served on time

  • Encourage the client to:

    • Drink/eat the supplement

    • Choose preferred flavors

  • Proper documentation is required

✅ Examples:

  • Burn patient → high-protein shake between meals

  • Elderly patient who barely eats → Ensure at 2 PM

  • Cancer patient with weight loss → nutritional supplement ordered

✅ NCLEX Tip:
If it’s ordered, it must be given + documented.

✅ SLIDE 8 — Serving Food #4

Encouraging Fluid Intake

🔑 Key Points:

  • Some clients have an order to:

    • Encourage fluids

    • Or force fluids

  • When entering the room → always offer small fluids

  • Fluids include:

    • Water, ice cream, ice pops

    • Gelatin (Jell-O)

    • Thin cereal, coffee, soda

  • Fluids help:

    • ✅ Prevent complications

    • ✅ Maintain bladder & bowel routine

  • Teach clients to:

    • Drink before they feel thirsty

    • Choose fluids they like

✅ Examples:

  • Dehydrated patient → offer water every time you enter

  • Constipated patient → increase fluid intake

  • Patient who hates water → offer gelatin or ice pops

✅ NCLEX Tip:
If they feel thirsty, they’re already dehydrated.

✅ SLIDE 9 — Serving Food #5

Encouraging Fluid Intake (cont.)

🔑 Daily Hydration Tips:

  • Keep a water bottle nearby

  • Drink water:

    • Before meals

    • With meals

  • Use water instead of carbonated drinks

  • Pack bottled water for the day

  • Drink enough low-fat milk

  • Try:

    • Sparkling water + lemon/lime

  • Eat enough fruits & vegetables

  • Drink extra fluids with exercise

✅ Examples:

  • Patient drinks only soda → nurse teaches switch to water

  • Forgetful patient → keep bottle at bedside

  • Active patient → increase fluids before & after activity

✅ NCLEX Tip:
Fruits & vegetables count toward fluid intake.

Serving Food #6

Restricting Fluid

🔑 Key Points:

  • Some clients have a fluid restriction order

    • Example order: Restrict fluids to 1,500 mL/day

  • It may be easier if:

    • ½ of fluids during the day

    • ½ in the evening

  • Fluid restriction includes ALL foods that are liquid at room temperature, such as:

    • Water

    • Jell-O

    • Ice cream

    • Popsicles

    • Soup broth

✅ Examples:

  • Heart failure patient → fluid restriction to prevent fluid overload & pulmonary edema

  • Kidney failure patient → fluid restriction to prevent swelling & electrolyte problems

  • A popsicle DOES count as fluid intake

✅ NCLEX Tip:
👉 If it melts, it counts as fluid.

✅ SLIDE 11 — Serving Food #7

Teaching

🔑 What the Nurse Must Teach:

  • Reinforce diet teaching using:

    • Verbal instructions

    • Written instructions

  • Consider:

    • Religious beliefs

    • Cultural food practices

  • Report adverse reactions to the diet

  • Use teach-back:

    • Client should repeat the diet instructions to confirm understanding

✅ Examples:

  • Diabetic patient repeats:
    “No regular soda, count my carbs” ✅

  • Muslim patient avoids pork → nurse works with dietary services

  • Patient becomes nauseated after a new diet → nurse reports it

✅ NCLEX Tip:
👉 The BEST proof of understanding = teach-back

✅ SLIDE 12 — The Client Who Needs Assistance with Eating #1

🔑 Key Points:

  • Always encourage independence first

  • The nurse may:

    • Feed the client

    • Allow a family member to assist

  • When feeding:

    • Warn about very hot foods

    • Watch for:

      • Nausea

      • Pain

      • Trouble swallowing

  • Allow the client to do as much as they can themselves

✅ Examples:

  • Stroke patient holds spoon but can’t scoop → nurse assists with guiding, not full feeding

  • Weak postop patient → nurse feeds slowly & safely

  • Patient says food feels “stuck” → STOP feeding & assess for dysphagia

✅ NCLEX Tip:
👉 Safety + independence always come before speed

The Client Who Needs Assistance with Eating #2

🔑 TWO Special Populations:

1. The Visually Impaired Person

  • Most can eat independently

  • For temporary or severe blindness:

    • Describe food location using clock method
      (“Your chicken is at 12 o’clock.”)

    • Warn about hot foods

    • Cut food into small manageable pieces

    • Ask, don’t assume they need full feeding

⭐ Example:

  • “Your mashed potatoes are at 3 o’clock and your meatloaf is at 9 o’clock.”

2. The Person with a Swallowing Disorder (Dysphagia)

  • Work with speech therapist for correct consistency:

    • Thick liquids

    • Puree

    • Mechanical soft

  • Work with dietitian to ensure nutrition is adequate

  • Safety first:

    • Elevate head of bed

    • Feed slowly

    • Encourage patient to swallow after each bite

⭐ Example:

  • Stroke patient pockets food in cheek → switch to pureed diet + thick liquids.

🔥 NCLEX Tip:

If the patient starts coughing or choking → STOP feeding immediately.

✅ SLIDE 14 — The Client Who Needs Assistance with Eating #3

🔑 1. The Person Who Cannot Chew

  • Reasons:

    • Poor dental health

    • Missing teeth

    • Ill-fitting dentures

  • May need diet consistency modified

    • Mechanical soft

    • Puree

    • Soft foods

⭐ Example:

  • Elderly patient with no dentures → needs mechanical soft diet (soft chicken, mashed potatoes, soft veggies).

🔑 2. Documenting and Reporting

Nurses must document if the client has:

  • Poor appetite

  • Refuses meals

  • Difficulty chewing or swallowing

  • Nausea or vomiting

  • GI discomfort

  • Exact percentage of meal eaten

  • Fluid intake

  • Tube feeding amount

⭐ Example:

  • “Patient consumed 25% of meal; complained of nausea after 3 bites; notified RN.”

🔥 NCLEX Tip:

Inadequate intake → report to team leader & provider because it can delay healing.

House Diets

🔑 Also Called:

  • Regular diet

  • General diet

  • Full diet

🔑 Who gets this diet?

  • Clients in acute or extended care

  • Whose condition does NOT require a special diet

🔑 What this allows:

  • Wide variety of foods

  • Client chooses meals from a menu

  • Also called:

    • Select diet

    • Client-select diet

  • May be ordered as:

    • Regular diet as tolerated (DAT)

✅ Examples:

  • Young patient admitted for observation → regular diet

  • Post-op patient tolerating food → DAT

✅ NCLEX Tip:
House/regular diet = NO dietary restrictions

✅ SLIDE 18 — Modified Diets #1

🔑 Big Idea:

Modified (therapeutic) diets are part of treatment for disease

🔑 Why diets are modified:

  • To regulate nutrients in metabolic disorders

    • Example: Diabetes → carb control

  • To increase or decrease weight

  • To reduce edema by controlling sodium

    • Example: Heart failure → low sodium

  • To aid digestion

    • Avoid foods that irritate the stomach

  • To help overworked organs rest

    • Example: Kidney or liver disease

✅ Examples:

  • CHF patient → low-sodium diet

  • Diabetic patient → carbohydrate-controlled diet

  • Gastritis patient → bland diet

  • Underweight patient → high-calorie diet

✅ NCLEX Tip:
If the question mentions a disease, think:
👉 “What diet modification does this condition need?”

Modified Diets #2

🔑 Continuation of therapeutic diets

Why a therapeutic diet may be ordered:

  • To eliminate a food the body cannot tolerate
    (Example: Lactose intolerance → lactose-restricted diet)

  • To slow overactive intestinal motility
    (Example: Diarrhea → low-fiber or low-residue diet)

Classifications of modified diets:

  1. Consistency & texture

  2. Energy level (calories)

  3. Nutrients

  4. Amount of food

  5. Specific allergens

⭐ Examples:

  • Allergy to eggs → diet eliminates egg-containing foods

  • Severe diarrhea → low-fiber diet

  • Patient with celiac disease → gluten-restricted diet

✅ SLIDE 20 — Modified Diets #3

Consistency Modifications

Consistency = how the food feels / how easy it is to swallow

🔑 Types:

1. Liquid Diets

Clear Liquid Diet

  • Water, broth, tea, gelatin

  • Inadequate in calories, protein, nutrients

  • Used short-term (≤3 days unless receiving IV/NG support)

Full Liquid Diet

  • Includes all clear liquids PLUS milk, cream soups, pudding

  • If used long-term → add supplements

2. Soft Diet

Types:

  • Regular soft / Digestive soft

    • Low in fiber, fat, connective tissue

    • Easy to digest

  • Mechanical soft

    • For oral problems, difficulty chewing

⭐ Examples:

  • Pre-op or post-op → clear liquids → full liquids → soft → regular

  • Patient with no teeth → mechanical soft

  • GI irritation → digestive soft

🔥 NCLEX Tip:

Sequence of advancing diet:
👉 Clear → Full → Soft → Regular

Modified Diets #4

Consistency Modifications (continued)

1. High-Fiber Diet

    ⚠ Milk-based diet is discouraged

    ✅ Examples:

    • GERD patient → bland diet

    • Ulcer patient → no coffee, no spicy food

    • Heartburn patient → avoid tomato sauce & citrus

    ✅ NCLEX Tip:
    Bland diet = NO spicy, acidic, fatty, caffeinated foods

    ✅ SLIDE 23 — Modified Diets #6

    Energy Value Modifications — High-Calorie Diet

    🔑 Used For:

    • Underweight individuals

    • Hyperthyroidism

    • Undernutrition

    • General malnutrition

    • Severe burns

    🔑 Diet Characteristics:

    • Over 3,000 calories/day

    • 130+ grams of protein

    • High in:

      • Protein

      • Carbohydrates

      • Fat

      • Vitamins & minerals

    • May need small, frequent meals

    • Always consider:

      • Food preferences

      • Eating habits

    ✅ Examples:

    • Burn patient → high-calorie, high-protein diet

    • Malnourished elderly patient → small frequent high-calorie meals

    • Hyperthyroid patient → needs extra calories due to ↑ metabolism

    ✅ NCLEX Tip:
    Burns + malnutrition = HIGH calorie & HIGH protein

    ✅ SLIDE 24 — Modified Diets #7

    Energy Value Modifications — Reduced-Calorie Diet

    🔑 Used For:

    • Weight loss

    • Obesity management

    🔑 What It Includes:

    • ✅ Healthy carbohydrates

    • ✅ Lean proteins

    • ✅ Healthy fats

    • ❌ NOT crash dieting

    • ❌ NOT starving

    ✅ Examples:

    • Patient with BMI of 38 → reduced-calorie diet

    • Pre-diabetic patient → weight loss diet to prevent diabetes

    ✅ NCLEX Tip:
    Safe weight loss = balanced calories, not starvation

— Modified Diets #8

Nutrient Modifications — Carbohydrate-Controlled Diets

🔑 Main Purpose:

  • To control blood sugar and fat levels

  • To delay complications of diabetes

🔑 Key Concepts:

  • Also called a Diabetic diet

  • Uses:

    • Plate model

    • Picture cues

    • Food groups

  • Carbohydrate counting focuses on:

    • Cereals

    • Rice

    • Pasta

    • Dairy

    • Fruits

    • Vegetables

  • Consistent-carbohydrate diet

  • Clients do NOT need special foods

  • Diet should be individualized to likes and dislikes

✅ Examples:

  • Diabetic patient eats:

    • ½ plate veggies

    • ¼ protein

    • ¼ carbs

  • Patient learns that:

    • Bread, milk, fruit all count as carbs

✅ NCLEX Tip:
Diabetic diet = CONSISTENT carbs, not “no carbs”

✅ SLIDE 26 — Modified Diets #9

Nutrient Modifications — Lactose-Restricted Diet

🔑 Why This Diet Is Needed:

  • Lactose intolerance = not enough lactase enzyme

🔑 Key Points:

  • Tolerance is different for each person

  • Many people:

    • Can’t tolerate a full glass of milk

    • But CAN tolerate:

      • Yogurt

      • Aged cheeses

      • Lactose-free milk

      • Milk taken with food

  • Severe cases must avoid:

    • Milk cooked into other foods (like bread)

✅ Examples:

  • Patient gets cramps after milk → switched to lactose-free milk

  • Patient tolerates yogurt but not ice cream → normal for lactose intolerance

✅ NCLEX Tip:
Lactose intolerance ≠ complete dairy elimination for everyone

✅ SLIDE 27 — Modified Diets #10

Nutrient Modifications — High- and Low-Fat Diets

✅ Fat-Controlled Diet

🔑 Used For:

  • Hyperlipidemia

    • High cholesterol

    • High triglycerides

  • To reduce risk of:

    • Coronary artery disease

🔑 What’s Modified:

  • Total fat

  • Saturated fat

  • Sometimes total calories too

✅ Examples:

  • Patient with cholesterol 280 → fat-controlled diet

  • Patient with CAD → limits saturated fats

✅ NCLEX Tip:
High cholesterol = LOW saturated fat

Modified Diets #11

Nutrient Modifications (cont.) — Low-Fat & High-Fat Diets

1. LOW-FAT DIET

🔑 Used For:

  • Malabsorption syndromes

  • Pancreatitis

  • Gallbladder disease

🔑 Guidelines:

  • Total fat (both saturated & unsaturated) limited to 25–30% of total calories

2. HIGH-FAT DIET

🔑 Used For:

  • Children with seizure disorders

  • Usually a ketogenic diet

🔑 Characteristics:

  • Extremely low carbohydrates

  • 80–90% fat

⭐ Examples:

  • Pancreatitis patient → low-fat diet to reduce pancreatic stimulation

  • Gallbladder disease → avoid fried/high-fat foods

  • Pediatric seizure patient → ketogenic diet to reduce seizure activity

🧠 NCLEX Tip:

Gallbladder + pancreatitis = low fat
Seizure child = keto high fat

✅ SLIDE 29 — Modified Diets #12

Nutrient Modifications — Protein-Controlled Diets

1. HIGH-PROTEIN DIET

🔑 Used For:

  • Healing

  • Burns

  • Malnutrition

  • Post-surgery

🔑 Protein sources:

  • Eggs

  • Meat

  • Poultry

  • Fish

  • Cheese

  • Milk

  • Commercial protein drinks

2. PROTEIN-RESTRICTED DIET

🔑 Used For:

  • Kidney disease

  • Liver disease (depending on severity)

🔑 Guidelines:

  • Protein amount depends on client’s weight

  • Should be:

    • High quality

    • Spread evenly throughout the day

  • May also require sodium and fluid restrictions

⭐ Examples:

  • Nephrology patient with kidney failure → protein-restricted diet

  • Burn victim → high-protein diet

  • Post-op patient → increased protein for wound healing

🧠 NCLEX Tip:

Kidney disease = limit protein
Burns/surgery = increase protein

✅ SLIDE 30 — Modified Diets #13

Nutrient Modifications (cont.) — Gluten-Restricted Diet

🔑 Used For:

  • Celiac disease

  • Gluten sensitivity

🔑 Foods Containing Gluten:

  • Wheat

  • Rye

  • Oats*

  • Barley

Note: Some oats are labeled gluten-free if processed safely.

🔑 Key Points:

  • Permanent elimination of gluten is necessary for celiac disease

  • Eliminating gluten reverses intestinal damage

  • Must read labels carefully — gluten is often used as a stabilizer in processed foods

⭐ Examples:

  • Celiac patient cannot eat:

    • Bread, pasta, crackers, cakes

  • Celiac-safe foods include:

    • Rice, corn tortillas, quinoa, gluten-free oats

🧠 NCLEX Tip:

Celiac = NO wheat, rye, oats, barley → lifelong.

Modified Diets #14

Nutrient Modifications (cont.) — Diets with Controlled Minerals and Electrolytes

Sodium-Controlled Diet

🔑 Key Sodium Limits:

  • Normal upper limit: < 2,300 mg/day

  • Moderate restriction: 1,500 mg/day

  • Strict/severe restriction: 500–250 mg/day

⚠ Important Teaching:

  • Salt substitutes (e.g., potassium salt)
    → ONLY with provider approval

  • Many “low-sodium” foods still contain hidden sodium

✅ Examples:

  • Heart failure (CHF) patient → 1,500 mg sodium/day

  • Severe edema/HTN patient → 500 mg sodium/day

  • Patient using salt substitute without asking → STOP & notify provider

✅ NCLEX Tip:
CHF + HTN + edema = LOW SODIUM

✅ SLIDE 32 — Modified Diets #15

Nutrient Modifications (cont.) — Controlled Minerals

Calcium, Phosphorus & Potassium

✅ Calcium-Modified Diet

  • High calcium → for osteoporosis

✅ Phosphorus-Modified Diet

  • Low phosphorus → for kidney failure

✅ Potassium-Modified Diet

  • High potassium → with diuretic use

  • Low potassium → with end-stage renal disease

✅ Examples:

  • Osteoporosis patient → increase calcium

  • Dialysis patient → low phosphorus & low potassium

  • Patient on Lasix (furosemide) → needs high potassium

✅ NCLEX Tip:
Lasix → LOSES potassium → replace potassium
Kidney failure → CAN’T excrete potassium → restrict potassium

✅ SLIDE 33 — Modified Diets #16

Diets Modified by Serving Size & Allergens

✅ Diets Modified by Serving Size

  • Some clients need small, frequent meals

  • Example:

    • Six meals/day instead of three

✅ Used For:

  • Nausea

  • Weakness

  • Cancer patients

  • Post-op patients

✅ Diets Modified for Allergens

  • Allergens = proteins that cause autoimmune/allergic response

  • Common allergens:

    • Milk

    • Eggs

    • Chocolate

    • Grains

    • Peanuts

    • Certain fruits

  • Allergen foods must be ELIMINATED

  • May need vitamin/mineral supplements if food groups are removed

✅ Examples:

  • Peanut allergy → completely avoid peanuts

  • Milk allergy → eliminate dairy + add calcium supplement

  • Chemo patient → 6 small meals/day

✅ NCLEX Tip:
Allergy = TOTAL elimination, not “small amounts”

Nutritional Support #1

Tube Feedings (Enteral Feedings)

🔑 What Tube Feeding Means:

  • Also called enteral nutrition

  • Used when the patient:

    • Is unconscious

    • Cannot swallow

    • Has mouth, throat, esophagus, or stomach cancer

    • Has oral trauma or surgery

    • Has anorexia

  • Also used when extra nutrition is needed:

    • Burns

    • Infection

    • Surgery

    • Fractures

✅ MOST IMPORTANT RULE:

👉 The patient MUST have a working GI tract

✅ Examples:

  • Stroke patient who cannot swallow → NG tube feeding

  • Burn patient → tube feeding for high protein & calories

  • Jaw wired shut → tube feeding

✅ NCLEX Tip:
If the GI tract works → choose ENTERAL
If the GI tract does NOT work → choose IV nutrition (TPN)

Nutritional Support #2

Tube Feedings (cont.)

🔑 Types of Formulas

  • Contain:

    • ✅ Protein

    • ✅ Fat

    • ✅ Carbohydrates

    • ✅ Vitamins

    • ✅ Minerals

  • Special formulas exist for specific diseases (renal, diabetic, high-protein, etc.)

🔑 Placement Sites

  • Through the nose into the stomach → NG tube

  • Through the abdominal wall into the stomach or jejunum → PEG / jejunostomy

✅ Examples:

  • Stroke patient → NG tube

  • Long-term feeding needs → PEG tube

  • Renal failure → renal-specific formula

✅ NCLEX Tip:
Short-term = NG tube
Long-term = PEG tube

✅ SLIDE 38 — Nutritional Support #3

Tube Feedings (cont.) — Tubes & Terminology

🔑 Key Vocabulary:

  • Nasogastric (NG): nose → stomach

  • Percutaneous: through the skin

  • PEG: percutaneous endoscopic gastrostomy

  • Endoscopic: placed with a camera/instrument

  • Gastrostomy: tube into the stomach

  • Button feeding device: small silicone device that replaces a long tube

✅ Examples:

  • Child with long-term feeding needs → button device

  • Adult post-stroke → NG tube

  • Cancer patient with swallowing problem → PEG tube

✅ NCLEX Tip:
PEG = long-term feeding access

✅ SLIDE 39 — Nutritional Support #4

(Image Slide: Tube Feeding Equipment)

🔑 What This Slide Is Showing (Visually):

  • Feeding bag

  • Tubing

  • Pump

  • Syringe for flushing

  • Tube connection to patient

🔑 What You Need to Know for Tests:

  • Tube feeds can be:

    • Continuous (all day via pump)

    • Intermittent/bolus (given at set times)

  • Tubes must be:

    • Flushed

    • Properly positioned

    • Monitored for complications

✅ Examples:

  • ICU patient → continuous pump feeding

  • Stable patient at home → bolus feedings with syringe

✅ NCLEX Safety Rule:
Feeding tube use = high aspiration risk if done incorrectly

Nutritional Support #5

Tube Feedings (cont.) — Nursing Considerations

🔑 Critical Nursing Responsibilities:

  • Follow Nursing Procedure 32-2

  • Clients may still eat by mouth if ordered

  • Document:

    • Tolerance

    • Intake

    • Any complications

  • Notify the provider if untoward signs develop

  • Head of bed MUST be elevated ~30° during feeding

✅ Examples:

  • Patient receiving tube feeding → bed at 30°

  • Patient starts coughing during feeding → STOP feeding & notify RN/provider

  • Patient allowed to sip water orally with tube feeding → must be provider-ordered

✅ NCLEX Priority Rule:
👉 HOB UP = Aspiration prevention

✅ SLIDE 41 — Nutritional Support #6

Intravenous Therapy — Parenteral Nutrition

🔑 What This Means:

  • Parenteral nutrition = nutrition through the vein

  • Used when the patient cannot use the GI tract

  • Includes:

    • TPN (Total Parenteral Nutrition)

    • PPN (Peripheral Parenteral Nutrition)

✅ TPN (Total Parenteral Nutrition)

  • Also called hyperalimentation

  • A specially calculated solution

  • Used when the GI tract is not working

  • Contains:

    • Carbohydrates

    • Protein

  • Requires a central venous catheter

✅ Examples:

  • Patient with bowel obstruction → TPN

  • Severe Crohn’s flare with no absorption → TPN

✅ NCLEX Tip:
If the GI tract does not work → TPN

✅ SLIDE 42 — Nutritional Support #7

Intravenous Therapy (cont.) — PPN

✅ PPN (Peripheral Parenteral Nutrition)

  • Same ingredients as TPN but:

    • Lower concentration

    • Given through a peripheral vein

  • Used for:

    • Temporary nutrition support

  • Must be:

    • Hypotonic or isotonic

  • Provides fewer calories than TPN

✅ Examples:

  • Patient NPO for a few days post-surgery → PPN

  • Mild GI rest → PPN

  • Long-term non-functioning gut → NOT PPN → TPN instead

✅ NCLEX Tip:
Short-term + peripheral vein = PPN
Long-term + central line = TPN

Food and Medication Interactions

(Image slide in your deck)

🔑 What this slide is testing:

Some foods change how medications work — they can:

  • Increase drug effects

  • Decrease drug effects

  • Cause dangerous side effects

✅ High-Yield Examples (NCLEX favorites):

  • 🍊 Grapefruit + many meds

    • Affects: statins, some cardiac meds, psych meds

    • 👉 Can cause toxic drug levels

  • Vitamin K foods + Warfarin

    • Spinach, kale, broccoli

    • 👉 Decreases the effect → ↑ risk of clots

  • ☕ Caffeine + stimulants

    • Increases:

      • Heart rate

      • Anxiety

      • Blood pressure

  • 🍺 Alcohol + sedatives/opioids

    • 👉 Risk for respiratory depression & death

  • 🥛 Calcium/dairy + some antibiotics

    • Decreases absorption (esp. tetracyclines, fluoroquinolones)

✅ NCLEX Rule:
If a med level is “off” → think FOOD interaction

✅ SLIDE 44 — Question #3

❓ Question:

True or False?
The bed should be put flat when the client is receiving a tube feeding.

✅ SLIDE 45 — Answer to Question #3

✅ Correct Answer: FALSE

🔑 Rationale:

  • The head of the bed must be elevated ~30°

  • If the bed is flat:

    • Stomach contents can move upward

    • Patient can aspirate

  • This can cause:

    • Aspiration pneumonia

    • Respiratory failure

    • Death

✅ Examples:

  • Nurse lowers bed to change sheets during feeding → dangerous

  • Patient receiving NG feeds → must stay at 30–45°

✅ NCLEX Priority:
👉 HOB UP during tube feeding — ALWAYS
