Practice Questions Fully Solved with Explanations
In which situation does bradycardia require treatment? - ANSWER Hypotension
Which intervention is most appropriate for the treatment of a patient in asystole? -
ANSWER Epinephrine
You arrive on the scene with the code team. High-quality CPR is in progress. An
AED has previously advised "no shock indicated." A rhythm check now finds
asystole. After resuming high-quality compressions, which action do you take
next? - ANSWER Establish IV or IO access
A monitored patient in the ICU developed a sudden onset of narrow-complex
tachycardia at a rate of 220/min. The patient's blood pressure is 128/58 mm Hg, the
,PETCO2 is 38mm Hg, and the pulse oximetry reading is 98%. There is vascular
access in the left arm, and the patient has not been given any vasoactive drugs. A
12-lead ECG confirm a supraventricular tachycardia with no evidence of ischemia
or infarction. The heart rate has not responded to vagal maneuvers. what is your
next action? - ANSWER Administer adenosine 6mg IV push
A patient has sinus bradycardia with a heart rate of 36/min. Atropine has been
administered to a toal does of 3 mg. A transcutaneous pacemaker has failed to
capture. The patient is confused, and her blood pressure is 88/56 mm Hg. Which
therapy is now indicated? - ANSWER Epinephrine 2 to 10 mcg/min
A patient is in cardiac arrest. Ventricular fibrillation has been refractory to a
second shock. Which drug should be administered first? - ANSWER Epinephrine 1
mg IV/IO
62-year-old man suddenly experienced difficulty speaking and left-sided weakness.
He meets initial criteria for fibrinolytic therapy, and a CT scan of the brain si
ordered. Which best describes the guidelines for antiplatelet and fibrinolytic
therapy? - ANSWER Hold aspirin for at least 24 hours if rtPA is administered
,A patient is in refractory ventricular fibrillation and has received multiple
appropriate defribillation shocks, epinephrine 1 mg IV twice, and an initial dose of
amiodarone 300mg IV. The patient is intubated. Which best describe the
recommended second does of amiodarone for this patient? - ANSWER 150 mg IV
push
A patient with sinus bradycardia and a heart rate of 42/min has diaphoresis and a
blood pressure of 80/60mm Hg. What is the initial does of atropine? - ANSWER
0.5mg
, A 35-year-old woman has palpitations, light-headedness, and a stable tachycardia.
The monitor shows a regular narrow-complex QRS at a rate of 180/min. Vagal
maneuvers have not been effective in terminating the rhythm. An IV has been
established. Which drug should be administered? - ANSWER Adenosine 6mg
A patient is in cardiac arrest. Ventricular fibrillation has been refractory to an
initial shock. If no pathway for medication administration is in place, which
method is preferred? - ANSWER IV or IO
What is the indication for the use of magnesium in cardiac arrest? - ANSWER
Pulseless ventricular tachycardia-associated torsades de pointes
A patient has a rapid irregular wide-complex tachycardia. The ventricular rate is
138/min. He is asymptomatic, with a blood pressure of 110/70 mm Hg. He has a
history of angina. What action is recommended next? - ANSWER Seeking expert
consultation
A patient is in cardiac arrest. High-quality chest compressions are being given. The
patient is intubated, and an IV has been started. The rhythm is asystole. What is the
first drug/dose to administer? - ANSWER Epinephrine 1mg IV/IO
