At logyanlo.in, our Day 23 Practice Test is crafted to help you master these concepts and feel confident heading into the 2025 exams.
Key Concepts in the Inflammatory System for Your Exam Prep
Let us explore the core topics of the Inflammatory System that you need to know for your AIIMS NORCET 9.0, KGMU, BTSC, or Raj CHO/NHM exams. We will focus on nursing responsibilities and exam-relevant points.
Basics of Inflammation
Inflammation is the body’s natural response to injury, infection, or irritants, aimed at protecting and initiating healing.
Types:
- Acute Inflammation: Short-term, occurs immediately after injury (e.g., swelling after a cut).
- Chronic Inflammation: Long-term, occurs with persistent stimuli (e.g., in autoimmune diseases like rheumatoid arthritis).
Process:
- Vascular Response: Blood vessels dilate, increasing blood flow (causing redness and heat) and permeability (causing swelling).
- Cellular Response: White blood cells (e.g., neutrophils, macrophages) migrate to the site to fight infection and remove debris.
- Chemical Mediators: Histamine, prostaglandins, and cytokines trigger inflammation and pain.
Signs:
- Redness, heat, swelling, pain, and loss of function (classic signs of acute inflammation).
Nursing Responsibilities:
- Assess for signs of inflammation, like localized redness or swelling at an injury site.
- Apply cold packs in the first 24–48 hours to reduce swelling, then switch to warm packs to promote healing.
- Educate patients on managing inflammation, like elevating a swollen limb to reduce edema.
Exams often test your understanding of inflammation signs, like identifying swelling as a hallmark of acute inflammation.
Wound Healing
Wound healing is the process by which the body repairs damaged tissue after injury.
Stages:
- Hemostasis (Immediate): Blood vessels constrict, and clotting occurs to stop bleeding (platelets form a clot).
- Inflammatory Phase (Days 1–4): Immune cells (neutrophils, macrophages) remove debris and fight infection.
- Proliferative Phase (Days 4–21): New tissue forms (granulation tissue), angiogenesis occurs, and epithelial cells cover the wound.
- Maturation Phase (21 Days to 1–2 Years): Collagen remodels, scar tissue strengthens, and the wound matures.
Types of Healing:
- Primary Intention: Clean wounds with minimal tissue loss (e.g., surgical incision), edges are approximated, minimal scarring.
- Secondary Intention: Larger wounds with tissue loss (e.g., pressure ulcers), heal by granulation, more scarring.
- Tertiary Intention: Delayed closure (e.g., infected wounds), closed surgically after infection clears.
Factors Affecting Healing:
- Nutrition: Protein, vitamin C, and zinc are essential for tissue repair.
- Infection: Delays healing by prolonging inflammation.
- Age: Older adults heal slower due to reduced cell turnover.
Nursing Responsibilities:
- Monitor the wound for signs of healing, like granulation tissue (red, moist tissue) in the proliferative phase.
- Ensure adequate nutrition, like advising protein-rich foods (e.g., eggs, fish) to support collagen formation.
- Educate patients on keeping the wound clean and dry to prevent infection.
Exams often test your knowledge of healing stages, like the role of macrophages in the inflammatory phase.
Wound Management
Wound management involves caring for wounds to promote healing and prevent complications.
Assessment:
Location and Size: Measure length, width, and depth (e.g., in centimeters).
Appearance: Note color (e.g., red for healing, black for necrosis), exudate (e.g., serous, purulent), and odor.
Surrounding Skin: Check for redness, swelling, or maceration (from excessive moisture).
Management Principles:
Clean the Wound: Use normal saline or antiseptic solutions to remove debris and reduce infection risk.
Debridement: Remove necrotic tissue (e.g., via surgical, enzymatic, or autolytic methods).
Dressings:
Hydrocolloid: For wounds with minimal exudate, promotes autolytic debridement.
Foam: For wounds with moderate to heavy exudate, absorbs moisture.
Alginate: For highly exudative wounds, forms a gel to maintain moisture.
Infection Control: Use topical antibiotics (e.g., silver sulfadiazine) for infected wounds as prescribed.
Moist Healing Environment: Maintain moisture to promote epithelialization (e.g., avoid letting the wound dry out).
Nursing Responsibilities:
- Change dressings as per protocol (e.g., daily for infected wounds, every 2–3 days for clean wounds).
- Monitor for signs of infection, like increased redness, warmth, or purulent discharge.
- Educate patients on wound care, like avoiding pressure on the wound to promote healing.
Exams often test your ability to choose appropriate dressings, like using foam for a wound with heavy exudate.
Gangrene
Gangrene is the death of body tissue due to a lack of blood supply or severe infection.
Types:
- Dry Gangrene: Caused by reduced blood flow (e.g., in peripheral artery disease), tissue becomes dry and blackened.
- Wet Gangrene: Caused by bacterial infection (e.g., in diabetic foot ulcers), tissue is swollen, moist, and foul-smelling.
- Gas Gangrene: Caused by Clostridium bacteria, produces gas in tissues, often after trauma or surgery.
Symptoms:
Discoloration (black, green, or purple), severe pain (early stage), numbness (later stage), and foul odor (in wet gangrene).
Management:
- Surgical Debridement: Remove necrotic tissue to prevent spread.
- Antibiotics: Broad-spectrum for infection (e.g., penicillin for gas gangrene).
- Amputation: In severe cases to save surrounding tissue.
- Hyperbaric Oxygen Therapy: For gas gangrene, increases oxygen to tissues to kill anaerobic bacteria.
Nursing Responsibilities:
- Monitor for signs of gangrene, like blackened tissue or foul-smelling discharge in a wound.
- Administer antibiotics as prescribed and monitor for side effects (e.g., allergic reactions).
- Educate patients on foot care, especially for diabetics, like checking for sores daily to prevent gangrene.
Exams often test your understanding of gangrene types, like identifying wet gangrene by its moist appearance and odor.
Prevention and Management of Pressure Ulcers
Pressure ulcers (also called bedsores) are injuries to the skin and underlying tissue caused by prolonged pressure, often in bedridden patients.
Risk Factors:
Immobility (e.g., paralyzed patients), poor nutrition, incontinence, and impaired circulation.
Stages:
- Stage 1: Non-blanchable redness, skin intact.
- Stage 2: Partial-thickness loss, shallow open ulcer or blister.
- Stage 3: Full-thickness loss, subcutaneous tissue visible.
- Stage 4: Full-thickness loss with exposed muscle, bone, or tendon.
- Unstageable: Base covered by slough or eschar, depth unknown.
Prevention:
- Repositioning: Turn patients every 2 hours to relieve pressure (e.g., supine to lateral).
- Support Surfaces: Use pressure-relieving mattresses (e.g., air mattresses) or cushions.
- Skin Care: Keep skin clean and dry, use moisture barriers for incontinent patients.
- Nutrition: Ensure adequate protein and calorie intake to support skin integrity.
Management:
Debridement: Remove necrotic tissue (e.g., wet-to-dry dressings for autolytic debridement).
Dressings: Use hydrocolloid for Stage 1–2, foam or alginate for Stage 3–4 with exudate.
Infection Control: Treat infections with antibiotics (e.g., topical metronidazole for odor).
Surgical Intervention: For Stage 4, may require flap surgery to cover the defect.
Nursing Responsibilities:
- Use the Braden Scale to assess pressure ulcer risk (scores <18 indicate high risk).
- Inspect skin daily, especially over bony prominences (e.g., sacrum, heels).
- Educate caregivers on repositioning techniques to prevent pressure ulcers in bedridden patients.
Exams often test your knowledge of pressure ulcer stages, like identifying Stage 3 by visible subcutaneous tissue.
