Flashcard 1 Q: What does an Arterial Blood Gas (ABG) test measure? A: • pH (acidity) • Oxygen (O₂) • Carbon dioxide (CO₂) 👉 To evaluate lung function ⸻ 🧠 Flashcard 2 Q: Why is ABG taken from an artery, not a vein? A: Because it measures gases before reaching tissues → more accurate for lung function ⸻ 🧠 Flashcard 3 Q: What is PaO₂? A: Partial pressure of oxygen → measures how well O₂ moves from lungs to blood ⸻ 🧠 Flashcard 4 Q: What is PaCO₂? A: Partial pressure of carbon dioxide → reflects how well CO₂ is removed ⸻ 🧠 Flashcard 5 Q: What does pH indicate in ABG? A: Hydrogen ion (H⁺) concentration → acidity/alkalinity of blood ⸻ 🧠 Flashcard 6 Q: What is the normal blood pH? A: 7.35 – 7.45 (slightly alkaline) ⸻ 🧠 Flashcard 7 Q: What happens if pH < 7.35? A: Acidosis ⸻ 🧠 Flashcard 8 Q: What happens if pH > 7.45? A: Alkalosis ⸻ 🧠 Flashcard 9 Q: What is the role of HCO₃⁻ (Bicarbonate)? A: Acts as a buffer → prevents pH changes ⸻ 🧠 Flashcard 10 Q: What is O₂ Saturation (O₂Sat)? A: Percentage of hemoglobin carrying oxygen ⸻ 🧠 Flashcard 11 Q: What is O₂ Content (O₂CT)? A: Total amount of oxygen in blood ⸻ 🧠 Flashcard 12 (Important Normals) Q: Normal ABG values? A: • pH: 7.35–7.45 • PaO₂: 75–100 mmHg • PaCO₂: 38–42 mmHg • HCO₃⁻: 22–28 mEq/L • O₂Sat: 94–100% ⸻ 🧠 Flashcard 13 Q: Common site for ABG sampling? A: Radial artery (wrist) ⸻ 🧠 Flashcard 14 Q: Other sites for ABG collection? A: • Brachial artery • Femoral artery ⸻ 🧠 Flashcard 15 Q: Why is the syringe pre-heparinized? A: To prevent clotting ⸻ 🧠 Flashcard 16 Q: When should ABG sample be analyzed? A: Within 30 minutes ⸻ 🧠 Flashcard 17 Q: What to do if analysis is delayed? A: Put sample on ice ⸻ 🧠 Flashcard 18 (Tricky 🔥) Q: What happens if air enters the sample? A: Alters gas values → incorrect results ⸻ 🧠 Flashcard 19 (Exam Trap ⚠️) Q: What is a common sampling error? A: Taking venous blood instead of arterial ⸻ 🧠 Flashcard 20 Q: Other causes of incorrect ABG results? A: • Too much/too little heparin • Delay in transport • Air bubbles Flashcard 1 Q: What does an Arterial Blood Gas (ABG) test measure?

🧴 1. SKIN ASSESSMENT – DETAILED NOTES 📄 ⭐ Purpose of Skin Assessment * Identify early signs of breakdown * Detect circulation or oxygenation issues * Prevent pressure injuries * Monitor healing or worsening conditions 🧠 What You Assess (Head-to-Toe Skin Check) 🔹 1. Temperature * Warm = normal * Cool = ↓ circulation * Hot = infection/inflammation 🔹 2. Color * Pallor → anemia / ↓ oxygen * Cyanosis → poor oxygenation (BLUE = BAD) * Redness → inflammation / pressure 🔹 3. Turgor * Pinch skin (usually chest or forehead) * Normal = snaps back quickly * Tented = dehydration 🔹 4. Moisture * Dry → dehydration * Diaphoretic → fever, stress * Excess moisture → breakdown risk 🔹 5. Integrity * Intact vs open areas * Look for: * wounds * tears * ulcers 🔹 6. Capillary Refill * Press nail bed * Normal = < 2 seconds * Delayed = poor perfusion 🔹 7. Edema * Swelling = fluid buildup * Check severity (pitting scale) 🚨 PRIORITY AREAS TO CHECK * Bony prominences (sacrum, heels, elbows) * Skin folds (obese patients) * Under devices (oxygen tubing, stockings) * Areas with ↓ sensation ⚠️ HIGH-YIELD FINDINGS * Non-blanchable redness = Stage 1 pressure injury * Cool, pale skin = ↓ perfusion * Moist skin = ↑ breakdown risk 🩹 2. SKIN TRAUMA & PRESSURE ULCERS – DETAILED NOTES 📄 ⭐ What is Skin Trauma? Damage to the body’s protective barrier ⚠️ Causes of Poor Wound Healing * Malnutrition * Poor blood flow * Infection * Smoking * Medications (steroids) * Age 🧬 Wound Healing Phases 1. Inflammatory * Redness, swelling * Body sends immune cells 2. Proliferative * New tissue forms * Wound starts closing 3. Maturation * Remodeling * Scar forms 👉 Know the ORDER!! 🔥 Types of Wound Healing * Primary intention → clean, closed (sutures) * Secondary intention → open wound heals slowly * Tertiary intention → delayed closure 🚨 PRESSURE INJURIES ⭐ Causes: * Pressure * Friction * Shearing ⭐ Risk Factors: * Immobility * Incontinence * Poor nutrition * ↓ mental status 🔴 STAGES (VERY TESTED) Stage 1: * Non-blanchable redness * Skin intact Stage 2: * Partial thickness * Blister / shallow wound Stage 3: * Full thickness * Fat visible Stage 4: * Muscle or bone exposed Unstageable: * Covered with slough/eschar Deep Tissue Injury: * Purple/maroon skin 🚑 INTERVENTIONS (PRIORITY CARE) * Turn every 2 hours * Keep skin clean and dry * Use barrier creams * Promote nutrition (protein!!!) * Assess skin daily ❌ DO NOT: * Massage reddened areas ⚠️ COMPLICATIONS * Infection * Dehiscence (wound opens) * Evisceration (organs out = emergency) 🧴 3. SKIN CONDITIONS – DETAILED NOTES 📄 ⭐ COMMON CONDITIONS 🔹 Dryness / Pruritus * Dry, itchy skin * Causes: * dehydration * irritants * allergies Treatment: * Moisturizers * Antihistamines * Steroids 🔹 Urticaria (Hives) * Raised, itchy welts * Blanch with pressure Treatment: * Antihistamines * Steroids * Epinephrine (severe) 🔥 Psoriasis (VERY TESTED) * Chronic autoimmune disorder Signs: * Silvery scales * Red plaques * Common areas: * elbows * knees * scalp Treatment: * Steroids * UV therapy * Biologic drugs 🔥 Cellulitis (IMPORTANT) * Bacterial infection Signs: * Red * Warm * Swollen * Painful Treatment: * Antibiotics * Elevate extremity 🔥 Shingles (VERY TESTED) * Reactivation of chickenpox Signs: * Painful vesicles * Burning/tingling Key Point: 👉 Contagious to people who never had chickenpox 🔥 Skin Cancer Types: * Basal cell * Squamous * Melanoma (most dangerous) ⭐ ABCDE RULE: * A = asymmetry * B = border * C = color * D = diameter * E = evolving 🧠 Nursing Diagnoses: * Impaired skin integrity * Risk for infection * Pain * Disturbed body image 🛌 4
