Art of interviewing In an interview, what factor do we need to consider? Social Economic Cultural How does the provider pick up on subtle ques? Shifts in body language in addition to spoken word Patients will tell you what is wrong with them if you ask the right questions Questions Open Ended OLDCARTS Don't use medical jargon Confrontation Watch for subtle ques "You look upset discussing _____, lets talk about it" Points out something striking about the patient's behavior or statement ○ Directs the patient's attention to something of which they may or may not be aware of ○ You look upset, you sound uncomfortable about that, Is there a reason you look away from me as you speak What does good communication improve? Health outcomes by resolving symptoms and reducing patient's psychogical distress and anxiety 85% of all malpractice lawsuits are based on poor communication skills What should we implement during an interview? ACTIVE LISTENING Watch their body language, tone, eye contact, speech and spoken word Understanding of what is being said, body language and other non verbal ques Symptom SUBJECTIVE ~What the patient feels ~Described by the patient Can be influenced by culture, intelligence and socioeconomic background Constitutional Symptom Fevers, Chills, Weight Gain, Weight Loss Effect all symptoms Sign OBJECTIVE What the observer finds on the assessment Crackles, dry skin, bruising What are the basic interviewing techniques? Questions Silence Facilitation Confrontation Interpretation Reflection Support Transitions Silence Silence is ok, but limit to 2 minutes or less If a patient is silent, you are silent Can restart the conversation with, "What are you thinking about?" Should never be used with the overtalkative patients ○ Can indicate interest and support ○ Don't allow more than 2 minutes of silence ○ Ok to ask: What are you thinking about? You were saying? These things are hard to think about Facilitation Keeps the conversation going "Tell me more about..." Encourages a patient to continue talking without controlling the direction of the conversation ○ Verbal and nonverbal communication that encourages the patient to keep talking ○ Go on, Tell me more, uh huh, And then Interpretation Based on inference "It sounds as if you are afraid...." Based on inference rather than observation ○ The provider interprets the patient's behavior, encouraging the patient to observe their own role in the problem. ○ You seem happy about that, Are you afraid you've done something wrong?, I wonder if your ____ is related to _____ Reflection Repeat part of the statement made by the patient Pt: "I haven't worked since 2016" APRN: "You haven't worked since 2016? Lets talk about that" A response that mirrors what the patient has just expressed ○ Patient: I am nervous about starting a new medication ■ Provider: Nervous about starting a new medication? Support Build a trusting relationship with the patient by using reassurance and empathy Shows an interest in or understanding of a patient ○ I understand ■ Reassurance ● A response that conveys to the patient that the interviewer understands what has been talked about ● That's great you were able to stop smoking, I am glad you came in today - we are going to help you ■ Empathy ● Response that recognizes a patient's feelings and does not criticize ● It's an understand, not an emotional state of sympathy ● I know it is not easy ______, I'm sure ______ has caused you a large amount of anxiety Transitions "Now I am going to ask you questions about..." Used as guides to allow the patient to better understand the logic of the interviewers questions in order to have a good flow to change the topic ○ I am now going to ask you questions about ______, Now let's talk about______ What does a past medical hx all include?

Lecture InfoSpeaker / Instructor: InstructorCourse / Subject: Histology / Epithelial tissueMain ThemeEpithelia are cellular sheets that protect, secrete, and absorb; structure (cellularity, polarity, surface specializations) determines function and clinical behavior.Key TakeawaysBarrier principle: "Nothing gets into the body unless it crosses an epithelium." Epithelium is the primary barrier to entry.Polarity: Apical vs basal surfaces differ in structure and function (apical: cilia, microvilli, secretions; basal: attachment to connective tissue).Naming framework: First word = number of layers (simple vs stratified vs pseudostratified); second word = cell shape (squamous = flat, cuboidal, columnar).Special types: Endothelium (lines blood/lymph vessels), mesothelium (lines serous cavities).Function vs structure examples: Simple squamous for fast gas diffusion (alveoli); simple columnar with microvilli for absorption/secretion (intestine); pseudostratified ciliated for mucus clearance (trachea).Regeneration & cancer: Epithelia regenerate very fast; about ~90% of cancers are epithelial in origin (carcinomas).Microvilli vs cilia: Microvilli = plasma membrane extensions increasing surface area for absorption; cilia = motile projections that move mucus/particles.Topics CoveredEpithelium as a barrierStatement: only crosses epithelium enter the body.Example: Swallowed glass passes through lumen but does not enter body tissues unless epithelium breached.Clinical: Paper cut vs deep cut — bleeding indicates breach past epithelium and potential bacterial entry.Cellularity and extracellular spaceCells are tightly packed with almost no extracellular space in epithelial layers.Contrast: connective tissue has abundant extracellular matrix; epithelium lacks ECM and sits on connective tissue for support.Junctions and attachmentsTight junctions / adhesive junctions / desmosomes glue cells together to prevent leakage and maintain integrity.Hemidesmosomes attach epithelial basal surface to connective tissue to prevent lifting.Polarity: apical vs basalApical surface: free surface; may have cilia, microvilli, or secretory specializations; where function (secretion/absorption/movement) occurs.Basal surface: attaches to connective tissue; provides physical support and nutrient supply because epithelium is avascular.Nutrient source: epithelium obtains oxygen/nutrients by diffusion from the vascular connective tissue (areolar connective tissue with capillaries) beneath.Naming system and shapesFirst word = layers: "simple" = one layer; "stratified" = >1 layer; "pseudo(stratified)" = nuclei at different heights but all cells touch basal lamina.Second word = shape of apical cells: squamous = flat (thin for diffusion), cuboidal, columnar = tall (larger volume for secretion/storage).Combined examples: simple squamous, simple columnar, stratified cuboidal, pseudostratified ciliated columnar.Functional relationships and organ examplesSimple squamous: alveoli — minimal thickness for rapid O2/CO2 exchange.Simple columnar (nonciliated, microvilli): small and large intestine — microvilli massively increase surface area for absorption and secretion (mucus, enzymes).Pseudostratified ciliated columnar: trachea and some large bronchi — cilia move mucus ("ciliary escalator") to trap and clear inhaled particles; fallopian tubes use cilia to move egg.Mesothelium: visceral/parietal layers lining serous cavities (pleura, pericardium) — secretes small amount of serous fluid to reduce friction.Surface specializationsMicrovilli: extensions of the plasma membrane that increase apical surface area; abundant in absorptive epithelia (tons of microvilli in intestine).Cilia: motile, pair-like projections that move mucus or fluid along the epithelial surface (trachea, bronchi, fallopian tube).Regeneration, pathology, and clinical relevanceHigh regeneration rate of epithelia allows rapid repair but increases cell division risk; most cancers (~90%) are epithelial (carcinomas).Chronic irritation increases proliferation and mutation risk: e.g., chronic acid reflux / heartburn → repeated esophageal epithelial damage → increased risk of esophageal cancer.Functional tradeoffs: thin epithelia (simple) allow fast crossing of substances but provide less physical protection; stratified epithelia provide greater protection (uppercase P for emphasis when multiple layers).Pseudostratified vs stratified clarificationPseudostratified: nuclei at different levels create appearance of layers; all cells contact basal surface (not truly stratified).True stratified: cells stack and only basal layer contacts basal lamina; apical cells may be dead (e.g., outer keratinized skin layers).Practical/teaching notes and exam focusInstructor emphasized understanding structure → function instead of rote memorization of locations.Naming rules and visual recognition (apical shape, number of layers, presence of cilia/microvilli) are frequent exam targets.Instructor called out key test points: pseudostratified vs stratified distinction, simple squamous in alveoli, simple columnar in gut, pseudostratified ciliated in respiratory tract, epithelial regeneration and cancer risk.

CHARACTER Character A character is a person, animal, or being that takes part in a story. Characters help move the plot and experience conflicts. --- VI. TYPES OF MAJOR CHARACTERS 1. Protagonist ➡️ The main character of the story. The story usually focuses on their goals, struggles, and experiences. 🧠 Protagonist = MAIN CHARACTER --- 2. Antagonist ➡️ The character or force that opposes the protagonist. The antagonist creates obstacles or conflict for the protagonist. 🧠 Antagonist = OPPOSING FORCE Easy to remember: PROtagonist → PRO = main character you're following ANTagonist → ANTI = against the protagonist --- VII.

Latitude & Longitude THIS is important. Imagine Earth has an invisible grid around it. The grid helps us say exactly where a place is. There are two main directions: LATITUDE = up and down on a map Latitude tells you how far NORTH or SOUTH you are from the Equator. 🌎 Equator = 0° latitude Think: LATITUDE = LADDER 🪜 The lines look like they go across Earth, but latitude tells you NORTH or SOUTH. Examples: * Equator = 0° * North Pole = 90° N * South Pole = 90° S So: 40° N = 40 degrees north of the Equator. ⸻ 📍 4. Longitude Longitude tells you how far EAST or WEST you are from the Prime Meridian. The Prime Meridian is: 0° longitude It runs through Greenwich, England. Think: LONGITUDE = LONG lines that go from pole to pole Longitude goes: 0° → 180° East 0° → 180° West A ⸻ 🧠 EASIEST WAY TO REMEMBER. What does it measure? Starting point Latitude North ↕ South Equator = 0° Longitude East ↔ West Prime Meridian = 0° Memory trick: LAT = flat Latitude lines look flat/horizontal on most maps. LONG = long Longitude lines go long from pole to pole. ⸻ 🌎 5. Hemispheres “Hemi” means half. So a hemisphere is simply half of Earth. There are 4: Northern Hemisphere Above the Equator. Southern Hemisphere Below the Equator. Eastern Hemisphere East of the Prime Meridian. Western Hemisphere West of the Prime Meridian. ⸻ ⭐ 6. POLARIS QUESTION Your professor asks: If Polaris is 39° above the horizon, what is your latitude? Don’t panic. 😭 The rule: Polaris’s angle above the horizon = your latitude BUT this works in the Northern Hemisphere. So: Polaris = 39° Therefore: ✅ Latitude = 39° N That’s literally it. Why? Polaris is basically lined up with the North Pole. If you’re: * At the Equator → Polaris is about 0° above the horizon. * At 39° N → Polaris is 39° above the horizon. * At the North Pole → Polaris is about 90° above the horizon. So: Polaris angle = latitude Quizlet Q: Polaris is 39° above the horizon. What is your latitude? A: 39° N ⸻ 🕘 7. THE LONGITUDE MATH QUESTION This one looks scary because your professor wrote a bunch of stuff. But it’s really just two steps. Question: You set your watch to Greenwich Mean Time (GMT). You travel somewhere else. When the Sun is directly overhead, your watch says 9 AM. What is your longitude? First understand: ☀️ “Sun directly overhead” This means: It is local solar noon. In other words: The place you’re standing = NOON But your watch says: 9 AM GMT So: Noon - 9 AM = 3 hours You’re 3 hours behind Greenwich. ⸻ 🧮 Now the important math Earth rotates: 15° every hour This is something you should memorize. So: 3 hours × 15° = 45° Therefore: ✅ 45° West Why WEST? Because your location is experiencing noon later than Greenwich. Think: Greenwich already reached noon. Your location is still behind Greenwich’s time. So you’re WEST. The whole problem: 12 PM − 9 AM = 3 hours 3 × 15° = 45° Answer: ⭐ 45° W ⸻ ☀️ SUN ANGLE HIGH/DIRECT ANGLE ☀️ ⬇️ ⬇️ 🌎 Energy is concentrated → stronger heating 🔥 LOW ANGLE ☀️ ↘️ ↘️ ↘️ 🌎 Energy spreads out → weaker heating 🥶 🧠 Remember: STRAIGHT = STRONG ☀️ TILTED = WEAKER ☀️ ⸻ 📐 PERPENDICULAR Perpendicular = 90° Think: ⊥ One line is standing straight on another.
