A patient is in refractory ventricular fibrillation. High-quality CPR is in
progress. One dose of epinephrine was given after the second shock. An
antiarrhythmic drug was given immediately after the third shock. You are the
team leader. Which medication do you order next?
A. epinephrine 1 mg
B. epinephrine 3 mg
C. sodium bicarbonate 50 mEq
D. a second dose of the antiarrhythmic drug
A. epinephrine 1 mg
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 38 mm 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 confirms a supraventricular tachycardia with
no evidence of ischemia or infarction. The heart rate has no responded to
vagal maneuvers. What is your next action?
A. administer adenosine 6 mg IV push
B. administer amiodarone 300 mg IV push
C. perform synchronized cardioversion at 50 J
D. perform synchronized cardioversion at 200 J
A. administer adenosine 6 mg IV push
A 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 is ordered. Which best describes the guidelines for antiplatelet and
fibrinolytic therapy?
A. give aspirin 160 to 325 mg to be chewed immediately
B. give aspirin 160 mg and clopidogrel 75 mg orally
C. give heparin if the CT scan is negative for hemorrhage
D. hold aspirin for at least 24 hours if rtPA is administered
D. hold aspirin for at least 24 hours if rtPA is
administered
A 35-year-old woman has palpitations, light-headedness, and a stable
tachycardia. The monitor show a regular narrow-complex QRS at a rate of
180/min. Vagal maneuvers have not been effective in terminating the rhythm.
An IV has ben established. Which drug should be administered?
A. adenosine 6 mg
B. atropine 0.5 mg
C. epinephrine 2 to 10 mcg/kg per minute
D. lidocaine 1 mg/kg
A. adenosine 6 mg
Which intervention is most appropriate for the treatment of a patient in
asystole?
A. atropine
