1.How long does it take for brain cells to die withoutoxygen? 4-6 minutes. 2. Describe the difference between ligaments and tendons in terms of attachment. Ligaments: bone to bone Tendons: bone to muscle 3. One-rescuer CPR is given at a ratio of _____compressions to _____ breaths. 30 compressions to 2 breaths 4. List the proper steps when using an AED? 1. Cut off clothing covering chest 2. If possible shave off excessive hair on chest 3. Follow instructions on AED 4. Place pads 5. Make sure no one is touching the body 6. Start the shock. 5.What is the acronym SHARP used for? S: Swelling around wound H: Heat/pulsing from area A: Aches and pains at sight of area R: Redness of surrounding area P: Puss draining from injury . When bandaging a wound, when should you checkcirculation? How do you check 6 circulation? Check before and after putting on a bandage. To check, press the finger for a couple of seconds, and see if the white finger goes back to pink, making sure circulation is good. It should only take a couple seconds on a healthy finger. This is called capillary refill or CSM. 7. What are the signs and symptoms of a fracture? Broken or cracked bone Visibly out of place or misshapen, swelling, bruising or bleeding, intense pain, inability to move. Open (Compound): Broken bone punctures skin Closed (Simple): Broken bone doesn’t puncture skin .What is the difference between first, second, thirdand fourth degree burns? 8 First: superficial layer of skin, redness Second: Blistering, weeping, partial or intermediate thickness Third: full thickness, dry, insensitive to touch Fourth: Right through to muscle or bone (sometimes burns through those), loss of burned part .What does RICE stand for? 9 For sprains, dislocations, fractures and strains R: Rest (no weight/don’t use) I: Immobilize (sling/splint) C: Cold/compression (ice for swelling) E: Elevate (raise to help swelling) 1 0.What is the longest, strongest bone in the body? Femur (thigh bone) 1 1. Where is the most common place on the body that a health care provider will take a pulse reading from? - B acteria multiply rapidly between 40f-140f or danger zone - Refrigerate within 2 hours in a fridge below 40f - Thaw frozen food in the fridge, cold water or microwave, never counter (bacteria multiply faster) 1 8. What is the difference between an epidemic and a pandemic? Epidemic is a disease outbreak that rapidly spreads in a small region Pandemic is a global epidemic that actively spreads to multiple regions around the globe Pandemic is a large-scale epidemic. 1 9. Briefly explain what a “broad-spectrum antibiotic" is and why it is commonly used to treat infectious agents. A broad spectrum antibiotic is an antibiotic that is used to treat a lot of infectious agents (works on 1 or 2 major bacterial groups). Common because it can fight multiple bacterias at once, so it’s helpful especially when you may not know what is infecting your patient, so you use this to treat it. 2 0. What is a superbug and why are superbugs considered highly dangerous? When you don't finish your recommended dose of antibiotics, it can create a superbug. A superbug is a strain of bacteria that has become immune to antibiotic drugs. Dangerous because it’s very hard to get rid of because it’s become resistant to many antibiotics that would kill non-superbug versions. 21. Define the terms and provide one example of each: a) Conventional Therapy:Conventional remedies (hospitalsuse this) that have been scientifically proven and used in medical establishments standardized and approved by the healthcare system. Considered western medicine. Standard medicine, chemo, radiation, surgery. b) Complementary Therapy:Natural and unconventionalremedies, paired with conventional therapies as well to help cure illnesses. Eases symptoms to improve quality of life. Meditation + chemo, green tea + conventional therapies. c) Alternative Therapy:Forego conventional therapy,use a more natural way to cure illnesses. Some can be harmful and delay access to proven treatments. Acupuncture, cupping. 22. Describe the three types of strokes and what makes them different from one another: a) I schemic:Blood clot blocks arteries leading to thebrain, preventing normal blood flow and oxygen. 87% of strokes are ischemic. b) Hemorrhagic:Breakage of a vessel within the brain,caused by trauma or ruptured aneurism. 13% of strokes are hemorrhagic. c) TIA:Mini stroke. that produces temporary (less than24 hours) stroke-like symptoms, however, still a medical emergency. Caused by a clot that doesn’t stay for a long period of time, and continues through the body. No permanent damage. Around 15% of strokes occur after TIA. 2 3. List 3 common symptoms of a stroke. Slurred speech, facial drooping, facial paralysis, inability to keep balance or keep hands over head, issues with swallowing, severe headache, nausea, vomiting and unilateral pupil RXN. 24. List all the structures in the upper and lower airway. Upper: pharynx, larynx, epiglottis Lower: trachea, bronchi, bronchioles, alveoli 3 2 9. Describe 2 cardiac conditions including 1 sign and symptom, 1 cause/risk factor, and 1 treatment for each. Heart murmur: Unique (whooshing, humming or rasping) heart sounds produced when turbulent blood flows past a valve or vessel Signs & symptoms: Extra, unexpected sound made by blood as it moves through the heart, trouble breathing, shortness of breath, chest pain, fainting Risk factor: Born with a defect (hole in heart), family history of heart diseases/heart murmurs Cause: Noisy blood flow through heart, flowing abnormally through heart and defective valves Treatment: Anti-arrhythmic medications, ACE inhibitors or ARBs (lower blood pressure) rrhythmia: A Irregularities in the heartbeat, when it is too fast, too slow or not beating at a steady pace Signs &symptoms: Racing feeling in chest, dizziness Risk factor: Overweight/not enough exercise Cause: Caused by electrical signals which tell the heart to pump don’t work properly Treatment: Pacemaker to help the heart have a steady rhythm, medicines, surgery on heart 3 0. What is asthma and what are two asthmatic triggers? Asthma is a condition that is caused by inflammation of and muscles tightening around the airways, making it hard to breathe. Symptoms include: - Coughing - Wheezing - Shortness of breath Triggers: - Allergies like pollen or dust - Smoke/fumes and pollution 3 1. What covers a wound? Dressing 3 2. What is the compression rate for adult CPR? 100-120 bpm 5
