unit 1-1 Flashcards
(29 cards)
1
Q
when to call rapid response-5
A
- staff concerned
- change in pt condition
- MEWS score (modified early warning system)
- fy concern
- s/s sepsis
2
Q
first s/s sepsis-2
A
confusion, increase RR
3
Q
keys for ACLS-5
A
- look, listen, feel for resp and pulse
- compression rate 30:2, now 100-120
- continuous compression w advanced airway
- defibrillation part of BLS
- start compressions w/n 10 sec of cardiac arrest
4
Q
BLS overview-4
A
- push at least 2 in for adults, allow complete recoil
- minimize interruptions
- give effective breaths
- avoid excessive ventilation
5
Q
sites for IO-3
A
humeral head (considered central line), tibial plateau, sternum
6
Q
ETT medications-5
A
lidocaine, epinephrine, vasopressin, atropine, narcan
7
Q
defibrillation procedure-5
A
- pads on chest
- charge
- “clear”
- shock
- continue CPR for 2 min then reassess rhythm
8
Q
AED-2
A
rhythm analysis, continue CPR if no shock advised
9
Q
cardioversion-3
A
must have pulse, Vtach, SVT, Afib
- low current and synchronized w R wave
- disrupts ectopic foci
10
Q
ventricular fibrillation
pulseless ventricular tachycardia-3
A
- start CPR and call for defib
- shock, CPR (2 min); shock, CPR, epi (2 min); shock, CPR, amiodorone 300mg (2min); shock, CPR, epi; shock, CPR, amiodorone 150mg (no more)
- other drugs lidocaine, procainamide, sodium bicarb
11
Q
torsades de pointes-3
A
- polymorphic VT
- give magnesium
- caused by prolonged QT plus low mag level
12
Q
pulseless electrical activity (PEA)-5
A
- electricity w/o a pulse-> pump problem
- CPR
- treat cause
- epinephrine only
- may use narcan if suspect opoid overdose
13
Q
asystole-5
A
- CPR
- epi
- confirm in 2 leads to look for vfib
- treat cause
- transcutaneous pacemaker
14
Q
Hs-5
A
- hypoxia
- hydrogen ion (acidosis)
- hypovolemia
- hypo/hyperkalemia
- hypothermia
15
Q
Ts-5
A
- tension pneumothorax
- tamponade
- toxins
- pulmonary thrombosis
- coronary thrombosis
16
Q
symptomatic bradycardia-4
A
- atropine
- treat cause
- transcutaneous pacing
- dopamine or epi drip
17
Q
transcutaneous pacemaker-4
A
- symptomatic brady, asystole
- external pads
- demand mode
- sedation/analgesia as needed
18
Q
tachycardia- 3 questions
A
- is it narrow (SVT) or wide (VT)?
- is it stable (drugs) or unstable (cardiovert)?
- VT vs SVT
19
Q
cardioversion drugs-3
A
adenosine (SVT), cardizem, amiodorone
20
Q
oxygen
A
100% or 15L/min
21
Q
epinepherine-4
A
- vasoconstrictor
- alpha and beta-adrenergic effects
- for VF, pulseless VT, asystole, PEA, bradycardia, hypotension
- 1mg push q 3-5min
22
Q
atropine-3
A
- syptomatic bradycardia
- 0.5-1mg q 3-5min IV push
- not given in PEA or asystole
23
Q
amiodorone (cordarone)-4
A
- reduce membrane excitability
- prolongs action pot and retards refractory period to terminate VT and VF
- alpha and beta adrenergic blocking
- cardiac arrest 300mg then 150mg
24
Q
adenosine-5
A
- slows conduction through AV node
- paroxysmal supraventricular tachycardia
- short pause in rhythm after push-crash cart ready
- half-life 10 sec, duration 1-2min; 6mg, 12mg, 12mg (only 3 given)
- pt must be stable, increased HR, warm
25
dopamine-2
1. vasoconstrictor to increase BP, bradycardia
| 2. consider need for fluids first
26
post-code goals-3
1. optimize cardiopulmonary function
2. transport to critical care unit
3. determine cause of arrest to prevent
27
capnography
if less than 10, compressions not adequate
28
measure core body temp-4
bladder cath w probe, esophageal probe, rectal, pulmonary artery cath
29
hypothermia electrolyte imbalances
cool- K, Mg, Phos, Ca decrease
| warm- K, Mg, Phos, and Ca increase
