Which of the following statements best describes the significance of the time delays
between cardiac arrest and defibrillation?
a) As long as CPR is effective prior, there is no change in outcomes based on time
from cardiac arrest to defibrillation.
b) The longer the time delay from CPR initiation to defibrillation the poorer the patient
outcomes.
c) Survival decreases by 1% every extra minute delay to defibrillation after CPR
initiated.
Give this one a try later!
b) The longer the time delay from CPR initiation to defibrillation the poorer
the patient outcomes.
Medications that decrease preload used in treating chest pain includes all except:
1) nitro patch
2) nitro infusion
,3) morphine
4) ASA
Give this one a try later!
4) ASA
Which of the following assessment findings would indicate a patient may be
developing cardiogenic shock? Select all that apply.
a) Weak, rapid pulse
b) Crackles on auscultation
c) Restlessness and anxiety
d) Delayed peripheral cap refill
e) Worsening chest pain
f) Increased urine output
Give this one a try later!
Weak, rapid pulse
Crackles on auscultation
Restlessness and anxiety
Delayed peripheral cap refill
Worsening chest pain
A 70-year old patient presents to the ED with dizziness and chest pressure. Her
respirations are 28/min and labored. Her 02 sats are 88% on RA so you apply oxygen.
Her skin is pale, cool, and clammy. Her radial pulse is very rapid and weak. You insert
an 18-gauge IV in her left ACF. You place her on the monitor and note following
rhythm:
Her blood pressure is 80/40 and she keeps muttering "I think I am going to pass out, I
am so dizzy..." What is the priority intervention for this patient at this time?
a) Obtain a 12-lead ECG and determine if her QRS complexes are wide or narrow.
b) Give 12 mg of Adenosine IVP
, c) Perform Vagal maneuvers
d) Prepare the patient for synchronized cardioversion
Give this one a try later!
The correct answer is D. This patient has presented with an
unstable tachycardia so the priority is to get her out of the
tachyarrhytmia as quickly as possible. While Adenosine may
be used for an unstable narrow-complex tachycardia, the
first dose is 6 mg, not 12 mg. A 12-lead would be obtained
eventually, but it is not a priority as we can already
determine her QRS complex is narrow from her rhythm
strip. Vagal maneuvers are reserved for stable patients with
a narrow-complex tachycardia.
Atropine is best indicated for which of the following?
1) Wide complex AV blocks
2) Second-degree type 1 AV block
3) First degree AV block
4) Sinus bradycardia with no symptoms
Give this one a try later!
2) Second-degree type 1 AV block
Which of the following is not a likely potential cause of cardiogenic shock?
a) Valvular disease
b) Cardiac tamponade
c) Acute decompensation of chronic heart failure
d) Myocarditis
e) Acute myocardial infarction
