Q

What is the chain of survival?

A
  • Early recognition and call for help - to prevent cardiac arrest
  • Early CPR - to buy time
  • Early defibrillation - to restart the heart
  • Post resuscitation care - to restore quality of life

If any step in the chain missed out, cannot proceed to next step

25
What are the 3 classifications of burn?
* Superficial burns * Partial thickness burns * Full-thickness burns
26
What are superficial burns?
* Involves only epidermis
27
What are some features of superficial burns?
* Red * Painful - tender * Blanches under pressure * Possible swelling, no blisters * Heals in ~7 days
28
What are partial thickness burns?
* Extend through epidermis into dermis
29
What are some features of partial thickness burns?
* Salmon pink * Moist/shiny * Painful * Blisters usually present * Heals in 7 - 21 days
30
What are full thickness burns?
* Through epidermis, dermis into underlying structures
31
What are some features of full thickness burns?
* Thick, dry * Pearly grey or charred black * May bleed from vessel damage * Painless * Require skin grafts to heal
32
How are burns and scalds managed?
* Monitor ABC as shock is likely * Pour cool running water over affected area for 10 minutes (has cooling effects, stops burning process) * Remove clothing and jewellery (if able) * Burnt area should be covered with clingfilm * Airway burns/smoke inhalation (intubation)
33
Why should cool water be poured over burns for 10 mins?
* Has cooling effect | * Stops burning process
34
What is the rule of nines used to assess?
Percentage of total body surface area affected by burns
35
What is the burn percentage value of head, arms, front, back, genitals, legs and hands?
``` Head - 9% Arms - 9% each Front - 18% Back - 18% Genitals - 1% Legs - 18% each Hands - 1% each ```
36
By which routes can poisons enter the body?
* Inhalation through lungs * Absorption through skin * Ingestion through mouth * Injection
37
How are poisons managed?
* ABC and ambulance * Find out cause of poisoning * If poison absorbed through skin, remove all clothing and irrigate * Collect vomited material/medications * Get time of poison ingestion * Find out how much has been taken * Rinse mouth
38
What should NOT be done in poison management?
DO NOT make casualty vomit to give fluids
39
What is hypovolaemic shock?
Shock caused by blood loss
40
What can cause hypovolaemic shock?
Haemorrhage
41
What are types of haemorrhage?

42
What should be done to manage haemorrhages?
PEPE
43
What is PEPE?
Used for haemorrhage control * Position casualty * Expose wound and check for foreign bodies * Pressure applied followed by firm dressing * Elevate limb if possible * (Tourniquets if trained)
44
How can pressure be applied to a wound with a foreign object embedded?
I ring bandage can be placed around foreign object and pressure applied
45
What are symptoms of shock?
* Nausea and vomiting * Thirst * Rapid breathing * Sweating * Fast and weak pulse * Pale, cold, clammy skin * Reduced consciousness * Confused and anxious

49
What are signs and symptoms of anaphylaxis?
* Collapse and unconsciousness * Swelling of throat and mouth * Difficulty in breathing * Alterations in heart rate * Drop in blood pressure * Abdominal pain, nausea and vomiting * Sense of impending doom * Nettle rash (hives), urticarial rash

51
What is the treatment of epilepsy?
* Maintain airway * Try to ease fall * Loosen tight clothing * Look for med alert tag * Monitor time of seizure - if more than 5 minutes or first seizure call 999
52
What should not be done during an epileptic fit?
Do not put anything in the mouth
53
What are the symptoms of hypoglycaemia?
* Shaking * Sweating * Anxiety * Dizziness * Hunger * Fast heartbeat * Impaired vision * Weakness, fatigue * Headache * Irritable

What are the symptoms of hyperglycaemia?
* Extreme thirst * Frequent urination * Dry skin * Hunger * Blurred vision * Drowsiness * Nausea
55
Why is hypoglycaemia an emergency?
It kills rapidly
56
What is the treatment for hypogylcaemia?
Glucose or glucagon
57
What is the treatment for hyperglycaemia?
Treat for shock/dehydration | insulin in hospital
58
What is acute coronary syndrome?
When coronary arteries that supply the heart muscle become blocked
59
What does partial blockage of coronary arteries cause?
Angina
60
What do fully blocked coronary arteries cause?
Myocardial infarction
61
What are signs and symptoms of acute coronary syndrome?
* Collapse, often without any warning * Breathlessness and cyanosis * Faintness and dizziness * Pale, cold and clammy skin * Nausea and vomiting * Sense of impending doom
62
What is done to manage acute coronary syndrome?
* ABCDE * 999 * Loosen clothing * Oxygen if breathless * GTN spray (angina) * Aspirin * Monitor and record vital signs * Reassure and keep calm
63
What is the early treatment for a suspected MI?
MONA * Morphine analgesia * Oxygen (high flow) * Nitroglycerin (sublingual) * Aspirin (300mg)
64
What is meningitis?
An infection of the mininges
65
