🦠 MICROBIOLOGY — WEEK 1 STUDY NOTES Microbiology Foundations Assigned reading: 1.1 What Our Ancestors Knew 1.2 A Systematic Approach 1.3 Types of Microorganisms 3.1 Spontaneous Generation 3.2 Foundations of Modern Cell Theor/y 1.1 What Our Ancestors Knew First: What is microbiology? Microbiology = the study of very small organisms and infectious agents. Microorganism / microbe = an organism that is generally too small to see without a microscope. Examples include: * Bacteria * Archaea * Fungi such as yeast and molds * Protozoa * Microscopic algae * Some parasites Viruses are also studied in microbiology, although viruses are acellular, meaning they are not made of cells. Important idea Microbes are NOT automatically bad. Many microbes are harmless or helpful. They: * help produce food * live naturally in and on our bodies * help ecosystems function * can be used to make medicines and other products Only some microbes cause disease. 🍞 Humans Used Microbes Before They Knew Microbes Existed Humans were using microorganisms for thousands of years before microscopes existed. One of the biggest examples is: Fermentation Fermentation = microorganisms change sugars/carbohydrates into substances such as: * alcohol * gases * organic acids Microbes involved can include: bacteria + yeast + molds Humans used fermentation to make: * bread * cheese * yogurt * beer * wine * pickled vegetables Easy example Yeast eats/metabolizes carbohydrates in bread dough. ↓ Yeast produces carbon dioxide (CO₂). ↓ Gas becomes trapped in the dough. ↓ Bread rises. Remember Fermentation = microbes changing sugars. ⸻ 🧊 Ötzi the Iceman Ötzi was a preserved human mummy approximately 5,300 years old. Scientists found evidence that he had: * Trichuris trichiura → a parasitic worm * Borrelia burgdorferi → bacterium that causes Lyme disease He also carried a fungus called Fomitopsis betulinus, which has laxative and antibiotic properties. Why does this matter? It shows that ancient people were trying to treat disease long before they understood microorganisms. ⸻ 🦠 Early Ideas About Disease Before microscopes, people didn’t know exactly what caused disease. Some cultures believed disease came from: * supernatural forces * angry gods * fate * bad air But some people began to realize that disease might spread between people. ⸻ Quarantine Ancient societies sometimes separated sick people from healthy people. This is called: Quarantine = separating potentially infected people to prevent disease spread. Even though they didn’t know what bacteria or viruses were, they understood that some diseases could spread. ⸻ 🚿 Sanitation Ancient civilizations also developed ways to improve sanitation. Examples included: * clean-water systems * drainage systems * sewers * aqueducts This was important because removing human waste and providing cleaner water can reduce disease transmission. ⸻ Important People From Early Medicine Hippocrates Who? Greek physician. Important idea: Disease had natural causes, rather than always being caused by supernatural forces. He is commonly called: “Father of Western Medicine.” Remember Hippocrates → disease has natural causes. ⸻ Thucydides Thucydides survived the Athenian plague. He noticed that people who survived the disease usually did not become sick from the same disease again while caring for infected people. This was an early observation of: Immunity Immunity = the body’s ability to resist a particular infection/disease. Remember Thucydides → early idea of immunity. ⸻ Marcus Terentius Varro Varro proposed that extremely tiny creatures that could not be seen might cause disease. He described tiny creatures entering the body through the: * mouth * nose This was an important idea because microscopes did not yet exist. Remember Varro → invisible tiny creatures may cause disease. ⸻ Ibn Sina / Avicenna Ibn Sina wrote the important medical work: Canon of Medicine He described ideas involving: * contagion * spread of disease * transmission through breath * isolation of sick people His work contributed to ideas that later became important for quarantine and infectious-disease control. ⸻ 🔬 Birth of Microbiology The development of the microscope completely changed science. For the first time, scientists could actually see microorganisms. ⸻ Antonie van Leeuwenhoek Extremely important name. In 1675, Antonie van Leeuwenhoek used powerful simple microscopes to observe tiny organisms. He called them: “animalcules” Today we know that some of the organisms he observed were: * bacteria * protists Remember Leeuwenhoek → first to describe bacteria/microorganisms seen through a microscope. Think: Leeuwenhoek = LOOKED at microbes. ⸻ ⭐ Golden Age of Microbiology Approximately: 1857–1914 During this period, scientists made major discoveries connecting microorganisms with: * fermentation * disease * medicine * infection Two huge names: Louis Pasteur and Robert Koch You are going to see both names repeatedly in microbiology. ⸻ Louis Pasteur Pasteur showed that microorganisms are responsible for fermentation. He also developed: Pasteurization Pasteurization = using controlled heat to kill/reduce microorganisms that cause spoilage or disease. He also worked on vaccines, including a vaccine against: rabies Pasteur will become especially important again in Section 3.1. Remember Pasteur → fermentation → pasteurization → vaccines → helped prove germ theory → disproved spontaneous generation ⸻ Robert Koch Koch showed that particular microbes could cause particular diseases. He identified microorganisms associated with diseases including: * anthrax * tuberculosis * cholera Remember Koch → specific microbe → specific disease. ⸻ 🧪 Basic Microbiology Laboratory Tools You don’t need to master these yet, but recognize the terms. Microscope → magnifies microbes. Stains/dyes → add color/contrast so microorganisms are easier to see. Growth media → nutrients/material used to grow microorganisms in the laboratory. Petri dish → shallow dish commonly used to hold growth media. Test tube → can contain liquid or solid/semi-solid growth media. Bunsen burner → flame that can be used during laboratory sterilization procedures. These will make much more sense once you start doing microbiology lab work. ⸻ 1.2 A Systematic Approach Now we move from discovering microbes to: “How do scientists organize and name all these different organisms?” ⸻ Taxonomy Definition Taxonomy = classification, description, identification, and naming of living organisms. Think: Taxonomy = biological organization system. ⸻ Carolus Linnaeus Linnaeus developed an important system for classifying organisms. The main levels used in classification include: Kingdom → Phylum → Class → Order → Family → Genus → Species A common memory trick: K P C O F G S King Philip Came Over For Good Soup You should know the order. ⸻ Species Species is the most specific/basic taxonomic level in this hierarchy. Example: Homo sapiens Homo = genus sapiens = species ⸻ Binomial Nomenclature Very important term. Binomial = two names. Every organism receives a scientific name consisting of: Genus + species Example: Homo sapiens Rules: Genus * first letter CAPITALIZED species * lowercase Both should normally be italicized when typed. Correct: Homo sapiens Not: Homo Sapiens ❌ homo sapiens ❌ Homo Sapiens ❌ ⸻ 🌳 Phylogeny Phylogeny = evolutionary relationship/history between organisms. Scientists can represent these relationships with a: Phylogenetic tree A phylogenetic tree shows how organisms are believed to be evolutionarily related. Organisms with a more recent common ancestor are considered more closely related. ⸻ Classification Changed Over Time Scientific classification did not stay the same. Linnaeus Originally divided nature into kingdoms including: * animals * plants * minerals The mineral kingdom was later abandoned. ⸻ Ernst Haeckel Added: Protista for many unicellular organisms. He later proposed Monera for organisms lacking nuclei. Remember: Haeckel → Protista ⸻ Robert Whittaker Developed a five-kingdom system: Animalia Plantae Fungi Protista Monera ⸻ 🧬 Carl Woese — VERY IMPORTANT Carl Woese used differences in: ribosomal RNA (rRNA) to study evolutionary relationships. His work helped establish the modern: THREE-DOMAIN SYSTEM 🟠 Bacteria 🟣 Archaea 🔵 Eukarya This is very important for your Week 1 material. Memorize: BAE Bacteria Archaea Eukarya ⸻ Bergey’s Manuals These are important references used in bacteriology. They help scientists: * classify bacteria * identify bacteria You probably don’t need every detail yet, but recognize the name: Bergey’s Manual ⸻ How Can Bacteria Be Identified? Scientists can identify microorganisms using things such as: Biochemical tests Look at chemical/metabolic characteristics. DNA/RNA analysis Examines genetic material. Serological tests Use reactions involving antibodies/antigens. ⸻ 1.3 Types of Microorganisms This section is VERY IMPORTANT. You need to understand the major groups. ⸻ 🌎 Three Domains of Life Again: 1. Bacteria 2. Archaea 3. Eukarya ⸻ Before We Continue: Two Big Cell Types You will hear these words constantly: PROKARYOTE vs EUKARYOTE Prokaryotic cells DO NOT have a membrane-bound nucleus. Bacteria = prokaryotic Archaea = prokaryotic Eukaryotic cells DO have a membrane-bound nucleus. Examples include: * animals * plants * fungi * protozoa * algae Super important: Prokaryote = NO nucleus Eukaryote = HAS nucleus ⸻ 🦠 BACTERIA Bacteria are: * unicellular * prokaryotic * found almost everywhere Some bacteria are helpful. Some bacteria can cause disease. Many bacteria have cell walls. You’ll learn much more about bacterial structures later. ⸻ 🌋 ARCHAEA Archaea are also: * unicellular * prokaryotic Like bacteria, they do not have a nucleus. BUT: Archaea ≠ Bacteria They differ in: * genetics * evolutionary history * metabolic pathways * cell membrane composition * cell wall composition Archaea occur in many environments. Important textbook point No archaea have been identified as human pathogens. Remember Bacteria + Archaea = Prokaryotes ⸻ 🔵 EUKARYA Eukaryotic microorganisms include: Algae Protozoa Fungi Helminths These have eukaryotic cells. ⸻ 🌿 ALGAE Algae can be: * unicellular * multicellular They are similar to plants in an important way: They perform photosynthesis. Photosynthesis = using light energy to make chemical energy/food. Remember: Algae → photosynthesis. ⸻ 🧫 PROTOZOA Protozoa are: * unicellular * eukaryotic * structurally more complex than bacteria Many are capable of movement. Remember Protozoa → single-celled eukaryotes, often motile. Motile = able to move. ⸻ 🍄 FUNGI Fungi studied in microbiology include: Yeasts Usually unicellular. Molds Usually grow as multicellular filament-like structures. Examples of fungi can be microscopic even though other fungi, such as mushrooms, are large. Remember Fungi → yeast + molds ⸻ 🪱 HELMINTHS Helminths = parasitic worms. You may think: “A worm isn’t microscopic. Why is it in microbiology?” Good question. Adult worms may be large enough to see. BUT their: * eggs * larvae can be microscopic. Therefore they are studied in microbiology. ⸻ 🦠 VIRUSES Viruses are different from cellular organisms. Viruses are ACELLULAR. Acellular = not made of cells. Viruses cannot reproduce independently. They require a: Host cell to reproduce. Remember Virus = acellular + requires host to reproduce ⸻ ⭐ Major Microorganism Comparison Group Cell type Nucleus? Important idea Bacteria Prokaryotic ❌ Some cause disease Archaea Prokaryotic ❌ Different from bacteria; no known human pathogens Fungi Eukaryotic ✅ Yeasts + molds Protozoa Eukaryotic ✅ Unicellular, often motile Algae Eukaryotic ✅ Photosynthesis Helminths Eukaryotic ✅ Parasitic worms Viruses Acellular No cell Need host to reproduce 🔥 This table is worth knowing very well. ⸻ 3.1 Spontaneous Generation This is mainly about one historical question: Where does life come from? People once believed: Spontaneous Generation Spontaneous generation = the belief that living organisms can arise from nonliving material. Examples people once believed: rotting meat → maggots mud → frogs old food → microorganisms Today we know this idea is incorrect. ⸻ Francesco Redi Redi tested whether maggots appeared spontaneously from meat. He compared meat that flies could reach with meat protected from flies. Result Maggots appeared when flies could access the meat. This suggested: Maggots came from flies — not directly from the meat. Remember Redi → meat + flies + maggots ⸻ John Needham Needham performed experiments with broth. He boiled broth and then observed microbial growth afterward. He interpreted this as evidence supporting: Spontaneous generation. Remember Needham → supported spontaneous generation. ⸻ Lazzaro Spallanzani Spallanzani disagreed. He boiled broth for longer and sealed the containers more carefully. The sealed broth did not show microbial growth. He argued that microbes came from contamination from the environment rather than being generated spontaneously. Remember Spallanzani → argued against spontaneous generation. ⸻ 🦢 Louis Pasteur’s Swan-Neck Flask Experiment This is VERY IMPORTANT. Pasteur used flasks with long curved necks. Why the curved neck? Air could enter the flask. BUT: Dust and microorganisms became trapped in the curved neck. So the broth remained uncontaminated. When microorganisms could reach the broth, microbial growth occurred. Conclusion Microorganisms did NOT spontaneously appear. They came from microorganisms already present in the environment. Pasteur helped establish the principle: “Life comes from life.” Exam memory Pasteur → swan-neck flask → disproved spontaneous generation. ⸻ 3.2 Foundations of Modern Cell Theory Now we move from: “Where do microbes come from?” to: “What is life made of?” Answer: CELLS ⸻ 🧬 Cell Theory The textbook describes the development of the idea that cells are the fundamental units of life. The central ideas are: 1. All living organisms are made of one or more cells. 2. The cell is the fundamental/basic unit of life. 3. Cells arise from pre-existing cells. Think: Life → cells → cells come from cells. ⸻ Robert Hooke In the 1660s, Robert Hooke examined cork with a microscope. He saw tiny compartments and called them: “cells” Remember Hooke → named/described cells. Don’t mix him up with Leeuwenhoek: Hooke → cells Leeuwenhoek → microorganisms ⸻ Matthias Schleiden Schleiden studied plants. He concluded that: Plants are made of cells. Remember: Schleiden → plants ⸻ Theodor Schwann Schwann studied animals. He concluded: Animals are made of cells. Remember: Schwann → animals ⸻ Robert Remak Remak provided evidence that cells form through the division of existing cells. ⸻ Rudolf Virchow Virchow strongly promoted the idea: Cells come from other cells. So: New cells do not spontaneously appear. ⸻ Easy Scientist Memory Hooke → saw/named cells Schleiden → plants Schwann → animals Remak/Virchow → cells come from existing cells ⸻ 🧬 Endosymbiotic Theory This sounds difficult, but the basic idea is simple. Endosymbiotic theory says: Mitochondria and chloroplasts were originally bacteria-like prokaryotic cells. A larger ancestral cell engulfed them. Instead of being destroyed, the cells developed a mutually beneficial relationship. Eventually, the engulfed bacteria evolved into: Mitochondria and Chloroplasts inside eukaryotic cells. ⸻ Evidence for Endosymbiotic Theory Mitochondria and chloroplasts have similarities to bacteria. They have: Their own DNA Their DNA resembles bacterial DNA. Their own ribosomes Their ribosomes resemble bacterial ribosomes. They reproduce through a process similar to binary fission Binary fission is a major way bacteria reproduce. Easy version Mitochondria and chloroplasts act strangely like bacteria because their ancestors were bacteria. ⸻ Lynn Margulis Lynn Margulis helped develop and promote the modern endosymbiotic theory. Remember Margulis → endosymbiotic theory ⸻ 🦠 Miasma Theory vs Germ Theory This distinction is very important. Miasma Theory Old idea: Disease comes from “bad air” associated with rotting material. Think: Bad smell → disease. This theory was eventually replaced. ⸻ Germ Theory Germ theory = many diseases are caused by microorganisms. Think: Microbe enters/infects body → disease Scientists whose work helped establish germ theory included: * Ignaz Semmelweis * John Snow * Louis Pasteur * Joseph Lister * Robert Koch ⸻ 🧼 Ignaz Semmelweis Semmelweis worked around childbirth. He noticed that patients treated by doctors and medical students had much higher rates of puerperal fever than patients cared for by midwives. Medical students often went from: autopsies → examining living patients without washing their hands. Semmelweis introduced handwashing with chlorinated lime solution. Result Maternal deaths fell dramatically. Remember Semmelweis → HANDWASHING ⸻ 💧 John Snow John Snow investigated cholera outbreaks in London. He connected cholera cases with: contaminated water. His work helped show that disease wasn’t simply coming from “bad air.” He is important in the history of: Epidemiology Epidemiology = study of disease patterns and spread in populations. Remember Snow → cholera + contaminated water + epidemiology ⸻ Joseph Lister Lister applied ideas about microorganisms to surgery. He promoted: * handwashing * cleanliness * sterilization * antiseptic techniques He used carbolic acid (phenol) to reduce infections during surgery. Result Surgical infections decreased. Remember Lister → antiseptic surgery ⸻ Robert Koch — Again Koch developed: Koch’s postulates These helped scientists determine whether a particular microorganism causes a particular disease. Basic idea: specific microorganism → specific disease You will learn Koch’s postulates in more detail later. ⸻ 🔥 WEEK 1 — PEOPLE YOU NEED TO KNOW Scientist/person Remember THIS Hippocrates Disease has natural causes Thucydides Early observation of immunity Varro Invisible creatures may cause disease Leeuwenhoek Observed microbes/bacteria Linnaeus Taxonomy + naming organisms Haeckel Added Protista Whittaker Five kingdoms Woese Three domains; used rRNA Redi Meat + flies + maggots Needham Supported spontaneous generation Spallanzani Evidence against spontaneous generation Pasteur Swan-neck flask; fermentation; germ theory Hooke Described/named cells Schleiden Plants are made of cells Schwann Animals are made of cells Remak/Virchow Cells come from cells Margulis Endosymbiotic theory Semmelweis Handwashing John Snow Cholera + contaminated water Lister Antiseptic surgery Koch Specific microbes cause specific diseases ⸻ 🚨 THE 15 THINGS I WOULD MEMORIZE FIRST Don’t try to memorize every paragraph tonight. Start here: 1. Microbiology = study of microorganisms. 2. Fermentation uses microbes to convert sugars into products such as alcohol, gases, or acids. 3. Leeuwenhoek observed microorganisms. 4. Pasteur and Koch were major scientists during the Golden Age of Microbiology. 5. Taxonomy = classification and naming of organisms. 6. Binomial nomenclature = Genus + species. 7. Three domains = Bacteria, Archaea, Eukarya. 8. Bacteria + Archaea = prokaryotes. 9. Prokaryote = no membrane-bound nucleus. 10. Eukaryote = has membrane-bound nucleus. 11. Virus = acellular and needs a host to reproduce. 12. Spontaneous generation = life arises from nonliving matter. 13. Pasteur’s swan-neck flask helped disprove spontaneous generation. 14. Cell theory = organisms are made of cells, cells are the basic unit of life, and cells come from existing cells. 15. Germ theory = microorganisms can cause disease. ⸻ 🧠 Super-Simple Week 1 Mental Map Think about the entire week’s reading as one story: PART 1 — Humans discover microbes People used microbes before knowing they existed. ↓ Leeuwenhoek sees them. ↓ Scientists begin studying them. ⸻ PART 2 — Scientists organize microbes Linnaeus → Taxonomy ↓ Woese → 3 domains ↓ Bacteria | Archaea | Eukarya ⸻ PART 3 — Scientists ask where life comes from People believed in spontaneous generation. ↓ Redi + Spallanzani question it. ↓ Pasteur disproves it. ↓ Life comes from existing life. ⸻ PART 4 — Scientists understand cells Hooke → cells ↓ Schleiden → plants Schwann → animals ↓ Remak/Virchow → cells come from cells ↓ Cell Theory ⸻ PART 5 — Scientists understand disease Old: Miasma = bad air causes disease ❌ ↓ New: Germ theory = microorganisms can cause disease ✅ ↓ Semmelweis → handwashing Snow → contaminated water Lister → antiseptic surgery Pasteur → microbes Koch → specific microbe causes specific disease

Natural Fibers Overview of Natural Fibers Natural fibers are derived from plants and animals, making them biodegradable and environmentally friendly. They have been used for thousands of years, with origins tracing back to ancient civilizations. Common types include cotton, jute, linen, wool, cashmere, and silk, each with unique properties and uses. Detailed Descriptions of Key Natural Fibers Cotton: Originating around 3000 BC, cotton is the most universal fiber known for its high absorbency and comfort. However, it wrinkles easily and shrinks when washed. Jute: Known as burlap, jute is one of the cheapest fibers, primarily used for carpet backing. It is brittle and breaks easily, typically woven in a plain weave. Linen: Derived from the flax plant, linen is elegant and durable, becoming softer with each wash. It is the strongest vegetable fiber, often used in high-end apparel. Wool: An animal protein fiber from sheep, wool is warm and resilient but may irritate sensitive skin. It requires dry cleaning to maintain its shape and is susceptible to moth damage. Cashmere: A luxurious fiber from goats, cashmere is soft and warm, with a yield of only half a pound per goat per year, making it rare and expensive. Silk: Produced by silkworms since 2460 B.C., silk is known for its strength and luxurious feel, often used in high-end fabrics like brocade and chiffon. Historical Context and Uses The use of natural fibers dates back to ancient civilizations, with cotton and silk being traded along the Silk Road. Jute and linen have been staples in various cultures for their durability and versatility in textiles. Wool has been a primary material for clothing in colder climates, while silk has been associated with luxury and wealth throughout history. Historical Context and Usage The use of cotton dates back to ancient civilizations, with evidence of its cultivation in the Indus Valley. Jute has been utilized for centuries, primarily in South Asia, for making ropes and burlap. Linen was favored in ancient Egypt for its coolness and comfort in hot climates, often used in burial garments. Wool has been a staple in colder regions, providing warmth and insulation for centuries. Cashmere became popular in Europe during the 18th century, symbolizing luxury and wealth. Silk was a major trade commodity along the Silk Road, influencing cultural exchanges between East and West. Manufactured Fibers Overview of Manufactured Fibers Manufactured fibers are created through chemical processes from substances that are not fibers at any stage of production. They allow for customization and enhancement of properties beyond what natural fibers can offer, such as durability and elasticity. Key Types of Manufactured Fibers Rayon: Made from regenerated cellulose, rayon was first produced in the U.S. in 1911. It is soft but loses strength when wet and should not be ironed with high heat. Nylon: Developed by DuPont in 1939, nylon is the first synthetic fabric, used in apparel and non-apparel items like tires and airbags. It is known for its quick-drying properties. Polyester: Originating in the 1930s, polyester is the most widely used manmade fiber, resistant to wrinkles but can feel clammy against the skin. Spandex: Introduced in 1959, spandex is highly elastic, used in athletic wear and swimwear, but is sensitive to chlorine. Applications and Characteristics Manufactured fibers are used in a wide range of products, from clothing to industrial applications, due to their versatility. They can be engineered for specific functions, such as moisture-wicking in athletic wear or durability in outdoor gear.

Absolutely. Your list is very broad, so the best way to study it is not to memorize every disease. We can turn it into a high-yield nursing reviewer based on: What is it? → What will I see? → What should I assess? → What should I do? → What medications/treatments matter? → What is the priority/emergency? → What should I teach? Below is a condensed master reviewer. I’ll keep it nursing-focused and use simple language. ⸻ 🩺 MEDICAL-SURGICAL NURSING REVIEWER 1.

MRI → detailed soft tissue/neurological/musculoskeletal imaging. ECG → electrical activity/ischemia/dysrhythmia. Troponin → myocardial injury. HbA1c → long-term glucose control. Creatinine/GFR → kidney function. INR → warfarin effect. Culture and sensitivity → organism + effective antimicrobial. Pulmonary function test → lung function/obstruction/restriction. ⸻ 💊 PHARMACOLOGY MASTER MEMORY MAP Instead of memorizing 100 medications individually, memorize the danger associated with each class: Drug/Class Think Insulin Hypoglycemia Opioids Respiratory depression Warfarin Bleeding + INR Heparin Bleeding + HIT Furosemide Fluid/electrolyte loss Digoxin Bradycardia/toxicity ACE inhibitors Hyperkalemia + cough/angioedema Beta blockers Bradycardia/hypotension Steroids Hyperglycemia + infection NSAIDs GI bleeding + kidney injury Statins Muscle/liver effects Bronchodilators Tachycardia/tremor Inhaled steroids Oral candidiasis Antibiotics Allergy + C. diff ⸻ 🚨 THE “PRIORITY QUESTION” METHOD When you’re stuck on an exam question, ask: 1. Is the airway threatened? If yes → AIRWAY 2. Is breathing compromised? If yes → BREATHING 3. Is circulation/perfusion compromised? If yes → CIRCULATION 4. Is there an acute neurological deterioration? Think neurological emergency. 5. Is there a safety risk? Falls, suicide, aspiration, seizures, etc. 6. Which patient is deteriorating? Unstable beats stable. ⸻ ⭐ TOP THINGS I WOULD MEMORIZE FIRST If you have limited study time, prioritize these: 🚨 Emergencies * Anaphylaxis → IM epinephrine * Stroke → BE FAST + last known well * MI → ECG + rapid intervention * Sepsis → early recognition + rapid treatment * Tension pneumothorax → emergency * Severe hypoglycemia → rapid glucose treatment * Status epilepticus → emergency * Increased ICP → neurological deterioration * Hemorrhage → control bleeding + perfusion * Severe burns → ABCs 💊 Medications * Insulin → hypoglycemia * Morphine → respiratory depression * Warfarin → INR/bleeding * Heparin → bleeding/HIT * Digoxin → pulse/potassium/toxicity * Furosemide → fluid/electrolytes * Nitroglycerin → hypotension + PDE-5 interaction * Steroids → infection/hyperglycemia * Antibiotics → allergy/C. diff * Inhaled steroids → rinse mouth 🧪 Labs * Hb → oxygen carrying * WBC → infection/immune response * Platelets → bleeding/clotting * INR → warfarin * Glucose → current sugar * HbA1c → long-term glucose * Creatinine/GFR → kidney * K⁺ → heart rhythm * Na⁺ → neurological/fluid balance * Culture → organism * Sensitivity → antibiotic choice 🩺 Nursing skills * Infection control * Medication administration * IVs * Oxygen * Suction * Tracheostomy * Chest tubes * Urinary catheter * Wound care * Ostomy care * Vital signs * Neurovascular assessment * Respiratory assessment ⸻ 📚 How I’d recommend studying this huge syllabus Don’t try to study all of these diseases in one sitting. Use system blocks: Day 1: Diabetes + cardiovascular Day 2: Respiratory + renal Day 3: GI + liver Day 4: Hematology + immune/infection Day 5: Neuro + musculoskeletal Day 6: Maternal/newborn Day 7: Pediatrics Day 8: Mental health Day 9: Pharmacology Day 10: Labs + diagnostics + clinical skills Day 11: Emergency/priority questions Day 12: Full mixed practice exam + review weak areas For each condition, make yourself answer only 5 questions: 1. What is happening? 2. What will I assess? 3. What is the biggest complication? 4. What will I do first? 5. What do I teach the patient? That approach will help you think like a nurse rather than memorize isolated facts, which matches the study framework you were given.
