1. A patient has a rapid *irregular wide-complex tachycardia*;
The ventricular rate is 138/min.;
It is asymptomatic, with a BP of 110/70 mmHG;
He has a h/o angina;
What action is recommended next?: a) Giving Adenosine: 6 mg IV bolus; b)
Giving Lidocaine: 1.5 mg IV bolus;
c) Performing synchronized cardioversion;
d) *Seeking expert consultation *;
2. What tests should be performed for a patient with a suspected stroke
within
2 hours of arrival?: non contrast CT scan of the head
3. SVT types: 1) Atrial fibrillation (A-fib);
2) Paroxysmal Supraventricular Tachycardia (PSVT):
3) Atrial Flutter (A-flutter);
4) Wolff-Parkinson-White syndrome;
,4. The patient is in *cardiac arrest*.
High-quality chest compressions are being given.
The patient is intubated, and an IV is being started.
The rhythm is *asystole*.
What is the first drug/dose to administer?: *Epinephrine 1 mg IV/IO*
5. *Transcutaneous Pacing*: Aka external pacing: is a temporary means of
pacing a patient's heart during a medical emergency.
It is accomplished by *gradually delivering pulses* of electric current (*50-100 mA*)
through the patient's chest until capture is reached (usually at a selected rate of 70),
which stimulates the *heart to contract* at a regular pace.
6. Which intervention is most appropriate for the treatment of a patient in
*asystole*?: *Epinephrine*
7. A patient with sinus *bradycardia* and a heart rate of 42/min is diaphoretic
and with a blood pressure of 80/60 mm Hg.
What is the *initial dose of atropine*?: *0.5 mg* of *Atropine*
8. A patient has sinus *bradycardia* with a heart rate of 36/min. *Atropine*
has been administered to a total dose of 3 mg. A *transcutaneous pacing*
, has failed to capture. The patient is confused, and her BP is *88/56
mmHg*. Which therapy is now indicated?: *Epinephrine infusion: 2-10
mcg/min*.
9. A monitored patient in the ICU developed a sudden onset of *regular
narrow-complex tachycardia* at a rate of 220/min.
The patient's BP is 128/88 mm Hg, the PETCO2 is 38 mm Hg, and the pulse
oximetry reading is 98%.
There is a vascular (IV) access in the left arm, and the patient has not been
given any basic active drugs.
A 12-lead ECG confirms *SVT* with no evidence of ischemia or infraction.
The HR has not responded to vagal maneuvers.
What is your next action?: Administer *adenosine 6 mg* IV push
10. A patient with possible STEMI has ongoing chest discomfort. What is a
*contraindication to nitrate* administration?: Use of a *phosphodiesterase
inhibitors* (eg. Viagra) within the previous 24 hours
