🧪 Sterilization Methods — Easy Notes + Mnemonic

🏥 Different sterilization methods are used to destroy microorganisms and make medical instruments safe for use.

📌 Autoclaving (Moist Heat'-121degree c, 15 min)
➡ Steam under pressure
➡ Used for: Surgical instruments, dressing packs, gloves, linen

📌 Dry Heat Sterilization
➡ Hot air kills microbes
➡ Used for: Glassware, metal tools, oils, powders

📌 Chemical Sterilization
➡ Best for heat-sensitive items
➡ Used for: Endoscope, catheter, plastic instruments

📌 Gas Sterilization (ETO)
➡ Ethylene oxide gas used
➡ Used for: Disposable syringes, electronic medical equipment

📌 Radiation Sterilization
➡ Gamma rays destroy microorganisms
➡ Used for: Gloves, IV sets, syringes

📌 Filtration
➡ Removes microbes from liquids
➡ Used for: Vaccines, serum, antibiotics

📌 Flaming
➡ Direct flame sterilization
➡ Used for: Inoculating loops & needles

📌 Incineration
➡ Burning contaminated waste
➡ Used for: Biomedical waste disposal

🧠
⚠ Important Notes:
✅ Autoclave = most common & effective method
✅ Dry heat → mainly glass & oils
✅ Heat-sensitive items → Chemical / Gas methods
✅ Filtration → used when heat can damage liquids

💡 Quick Trick:
“Heat-resistant items → Heat methods”
“Heat-sensitive items → Chemical/Gas/Filtration”

“Who Do You See First? 🩺 ABCs of Nursing Priority”
Caption:
"Nursing students, remember your ABCs?
💡Airway, Breathing, Circulation – the golden rule for patient priority.
A nurse is assigned to four patients on a medical-surgical unit. Which patient should the nurse assess first?
1️⃣Patient A: A 65-year-old postoperative patient with a patent IV line and blood pressure 130/78 mmHg, reporting mild incisional pain.

2️⃣Patient B: A 50-year-old with chronic obstructive pulmonary disease (COPD) who is alert but has a respiratory rate of 32 breaths/min and oxygen saturation of 88% on 2 L nasal cannula.

3️⃣Patient C: A 72-year-old patient with a history of hypertension, complaining of a mild headache, BP 160/90 mmHg, and denies chest pain.

4️⃣Patient D: A 60-year-old patient with type 2 diabetes scheduled for discharge today, who requests teaching on insulin administration.
Who will you see first? 🤔
