DONE: Emergency Medicine, Injections, and Phlebotomy Flashcards
best when done in order, not random, as the questions build off one another
Identify the initial four steps of BLS
- Assess the scene for safety
- Activate EMS and get AED
- Check for Pulse
- Begin CPR
what components are part of step 1 of BSL - assess the scene for safety?
- look for dangers - electrical wires, fire, weapons, glass, toxins, etc
- shout R U OK to victim
- check to see if they are breathing and call for help if you’re alone
during step 2 of BSL (activate emergency response system and get the AED), what would you do before calling 911 if someone has drowned/suffered asphyxia arrest?
provide 5 cycles or 2 minutes of CPR before calling 911
during step 3 of BSL - pulse check - for how many seconds should you feel the pulse for?
at least 5, no more than 10
what is the CPR ratio and how many BPM should you perform at?
30 compressions : 2 breaths at 100 bpm
allow recoil each time
how many cm or inches should you push down with each compression?
5 cm or 2 inches
which finger(s) should be used to lift the jaw in a head tilt-chin lift?
4 fingers - NOT the thumb
when would we use a jaw thrust instead of a head tilt-chin lift?
if a head or neck injury is suspected, 2 individuals are needed for this
how many seconds should each breath last?
1 second each
the nose should be unplugged during breaths - T/F?
FALSE. plug da nose silly!
you give a rescue breath, but fail to see the chest rise, what are your next steps?
- re-open the airway and attempt 2 breaths (1 sec ea) again
- if it still does not rise, perform a finger sweep to clear any obstruction
- if still unsuccessful, return to chest compressions
in the middle of CPR, the patient begins breathing, what do you do until EMS arrives?
roll them to their side and monitor vitals, provide O2, complete a secondary survey
your pt is now breathing, and we will perform a secondary survey until EMS arrives. what are the components?
SAMPLE S: signs and sxs A: allergies M: medications P: past medical hx L: last meal E: events related to injury
how do you check for responsiveness in a child from 0 yo - puberty?
tap the bottom of their foot
what is the compression : ventilation ratio in 1 yo- puberty if there are 2 rescuers? 1 rescuer? what is the compression depth for someone 1yo - puberty? 0-1 yo?
2 = 15:2 1 = 30:2
same as adults: 5 cm/2 inches
infants: 4 cm/1.5 inches
what is the compression technique for someone 1 yo - puberty?
one hand on chest, one on forehead
which artery(ies) are valid for a pulse check in someone 1yo - puberty? how about someone < 1 yo?
carotid or femoral
brachial or femoral
what are the factors that constitute “no pulse felt”
no pulse, HR < 60 bpm with signs of poor perfusion
call 911 after 5 cycles
what is the compression technique for someone 0-1 yo?
2 fingers just below the nipple line in the center of the chest do not press the bottom of the breast bone
if there are 2 rescuers, they can take both hands around the baby’s abdomen and place both thumbs to compress
infants: 4 cm/1.5 inches
which position should an infant’s head be in for maximal airway?
neck in neutral so the ear canal is level with the top of the infant’s shoulder, can use 1 finger to stabilize the chin if needed
how does rescue breath technique change for an infant
mouth covers infants nose and mouth
T/F: one should still give rescue breaths in someone who has a pulse but is not adequately breathing
TRUE
lone rescue breathing rate/minute in adults? infants? children?
adults: 1 every 5-6 seconds (10-12 bpm)
infants and children: 1 every 3-5 seconds (12-20 bpm)
how often should the pulse be checked in lone rescue breathing?
every 2 minutes
what are the risks of giving breaths too quickly or forcefully or with too much volume?
vomiting, aspiration, or pneumonia
what are the differences between a mild and severe airway obstruction?
good VS poor/no air exchange
can cough forcefully VS weak or no cough present
wheezing might be heard VS increased resp difficulty
severe also has cyanosis, unable to speak, clutching neck
steps to takes when someone has a mild airway obstruction?
encourage continued coughing and breathing efforts, dont interfere with their own attempts, stay with them and monitor conditions, activate EMS
steps to take when someone has a severe airway obstruction?
ask them if they are choking > if nodding yes > heimlich
the heimlich is used in adults and infants, T/F?
false, only adults
T/F - in heimlich, the fist should be placed directly under the sternum
F - it needs to be well below the sternum, but above the navel. Quick, forceful upward thrust in a J motion.
your heimlich patient becomes unresponsive, so you lower them to the ground and beging CPR - what is the first step?
do not check the pulse > start with compressions at 30:2
T/F - every single time you give breaths to someone with a foreign object, you should check for the object and perform a finger sweep?
false: yes, you should check for a foreign object every time, but should only remove something with your fingers if you can see it
how to perform heimlich on a pregnant or obese victim
chest thrusts with backward thrusts
how many back slaps and chest thrusts are performed in relief of choking in infants?
5 back slaps (each is a separate attempt to dislodge), 5 chest thrusts (1/second) until unresponsive
when is it ok to perform a blind finger sweep?
NEVERRRR
you are performing chest thrusts/back blows on an infant and they become unresponsive, what is your next step?
stop giving back slaps and begin CPR starting with compressions
when we are alone, when do we activate EMS? how about when there is someone else?
after 2 minutes of CPR
before starting CPR
what are the two forms of heat exhaustion? what signs/sxs tell us which one?
water depletion: excessive thirst, weakness, headache, LOC
salt depletion: nausea and vomiting, frequent muscle cramps, dizziness
above what body temperature do we enter heat exhaustion and stroke?
> 104 or 40.5 celcius
are coma and seizures seen in heat exhaustion or stroke?
stroke
treatment of heat exhaustion
Tx for orthostatic hypotension
rest in a cool environment, fluid rehydration, IV normal saline if orthostatic hypotension
treatment of heat stroke
cool body with water mist and standing fans, immerse in ice water bath (prepare for hypothermia), apply cold packs to axilla and groin, IV fluids if still hypotensive after previous TXS, monitor vitals and send to hospital
what medication to avoid in heat stroke
antipyretics
can alcohol cause hypo or hyperthermia?
hypo
temps categorizing mild/mod/severe hypothermia
89-94 (32-34.9 C), 82-88 (28-31.9 C), <82(28 C)
in what stage of hypothermia does the pt stop shivering?
moderate (they do shiver in mild)
in what stage of hypothermia do we see muscle rigidity? flaccidity?
moderate > severe
does acidemia or alkalemia occur in severe hypothermia?
acidemia
2 heart signs seen in severe hypothermia
v fib, asystole
hypo or hypertension in severe hypothermia?
hypo
pupils dilated or constricted in moderate hypothermia?
dilated
tx of hypothermia in all classes
fluid replacement with warm drinks and electrolyes
passive external rewarming
cover pt with an insulating blanket (external) so the body can generate its own (passive) heat
active external rewarming
application of warming blankets or heat baths (active and external)
risk associated with active external rewarming
warming the extremities can cause vasodilation > cool pooled blood moves back to the core > drop in core temperature > cardiac arrest
active core rewarming
rewarm with IV fluids and warmed humidified O2
how to transport someone who has hypothermia
head lower than feet
when to NOT do CPR in someone who is hypothermic?
