Exam 5: Medical Emergencies Flashcards
What causes migraine headaches?
constriction of blood vessels in the brain = increase pressure
What is a symptom associated with migraine headaches?
photophobia
What is a stroke also called?
cerebrovascular accident
What type of headache is associated with a stroke?
“the worst headache of my life”
What causes an ischemic stroke?
embolism in the vessels of the brain
What causes a hemorrhagic stroke?
aneurysm/trauma | rupture of blood vessel = bleed out
Which type of stroke is more fatal?
hemorrhagic = bleed out
What symptom/sign greatly contributes to a stroke?
hypertension
How can you differentiate between the 2 types of stroke?
CT will show if blood is present or not (ischemic)
What does FAST stand for?
facial droop | arm dropping | slurred speech | time to act
How can you assess arm dropping in suspected stroke patients?
have patient hold arms up palms up = if one begins to drop down = stroke
Signs and Symptoms of a Stroke.
headache | hemiparesis/hemiplegia | aphasia | AMS | HYPERTENSION
What is hemiparesis/hemiplegia?
weakness on one side of body
What is an important question to ask bystanders/family/friends about a stroke patient?
when was the last time patient was acting normal
What is the window of time from onset of stroke when a patient has a great chance of survival? What is it for really?
3hrs or less | clot-busting medication
In which stroke patient can receive clot busting medication?
ischemic only
What is a transient ischemic attack (TIA)?
stroke that lasts for a short time and resolves itself
What causes a TIA?
thrombotic particles get stuck in the blood vessel = block the vessel until it breaks free
Signs and Symptoms of TIA
stroke symptoms that last less than 24 hrs
How do you treat TIA?
treat it like a stroke
What are 3 conditions that can mimic a stroke?
hypoglycemia | postictal state | subdural/epidural bleeding
What is syncope?
temporary LOC due to short period of cerebral hypoxia
What are 4 causes of syncope?
hypoglycemia | lack of O2 | vagal stimulation | seizures
How do you transport patients who fainted?
SUPINE
Define seizure.
uncoordinated, random, chaotic electrical charges in the brain
What is a convulsion seizure?
has the tonic/clonic movement
What is tonic and clonic?
tonic = rigid muscles | clonic = jerking of extremities
What is an aura in seizures?
feeling that you know when a seizure is about to happen
What is the post-ictal state of a seizure?
patient is no longer seizing but is still in an altered mental state | doesn’t know what happened but is disoriented | still not normal self
What is Epilepsy?
disorder of having multiple seizures
Stages of a Seizure (Generalized/Convulsion)
Aura > Tonic/Clonic > clenching of jaw/biting of tongue > incontinence > post ictal state
What is a Focal seizure?
patient is conscious | a simple part of body is seizing
What is status epilepticus?
multiple seizures in one episode | patient does not get out of the post-ictal state
What are 4 structural causes of seizures?
tumor | infection | ICP | stroke
What are the 4 metabolic causes of a seizure?
hypoxia | hypoglycemia | overdose | Delirium-Tremens
What is delirium tremens?
people with alcohol abuse = used to having alcohol in system = withdraw = can cause seizures
What is a common type of seizure seen in kids? What is it due to?
febrile seizures = high fevers
What are the 5 things you must do for a Seizure case?
remove anything patient can hurt themselves on during a seizure | NEVER restrain | protect head by padding underneath it | LET them have the seizure | ALS
What is DM Type I also called? What is it?
juvenile onset | immune system attacks beta cells in pancreas = no insulin = insulin dependent DM
What is DM Type II?
have too much insulin in body (not insulin dependent)
What is the range for normal blood sugar?
80-120 mg/dl
What is the blood sugar range for hyperglycemia?
> 200 mg/dl
What is the blood sugar range for hypoglycemia?
60 mg/dl >
Signs and Symptoms of hyperglycemia
hypotension | dehydration | excited
Signs and Symptoms of Diabetic Ketoacidosis (DKA)
300-600 mg/dl | kussmaul respirations (huffing) | sweet, fruity odor
Treatment for diabetic cases
supine | O2 | oral glucose (hypoglycemia)
Treatment for inhaled poisons
move patient to fresh air | O2
How to treat patients who tried to commit suicide by buildup of CO in car?
call additional resources for extrication
Signs and Symptoms of skin contact poisons.
burns | itching | irritation
Removal method for powder poisons
BRUSH off first | RINSE with water
How do we treat poison contact in eyes?
remove contact lenses | irrigate 20 mins
What is used to treat ingested poisons?
Activated charcoal
Contraindications for active charcoal
N/V | corrosives, caustics or petroleum | decreased LOC
What is the dosage for activated charcoal?
1g per 1kg
How to treat injected poisons?
airway/O2 | transport
Signs and Symptoms of Sedative/Hypnotic drugs (barbiturates and benzos)
ataxia | bradycardia | hypotension | respiratory hypoxia
