Question:
What tests should be performed for a patient with a suspected stroke within 2 hours of arrival?
Answer:
non contrast CT scan of the head
Question:
SVT types
Answer:
1) Atrial fibrillation (A-fib);
2) Paroxysmal Supraventricular Tachycardia (PSVT):
3) Atrial Flutter (A-flutter);
4) Wolff-Parkinson-White syndrome;
Question:
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?
Answer:
*Epinephrine 1 mg IV/IO*
Question:
*Transcutaneous Pacing*
Answer:
,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.
Question:
Which intervention is most appropriate for the treatment of a patient in *asystole*?
Answer:
*Epinephrine*
Question:
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*?
Answer:
*0.5 mg* of *Atropine*
Question:
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?
Answer:
*Epinephrine infusion: 2-10 mcg/min*.
Question:
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?
Answer:
Administer *adenosine 6 mg* IV push
Question:
A patient with possible STEMI has ongoing chest discomfort. What is a *contraindication to
nitrate* administration?
Answer:
Use of a *phosphodiesterase inhibitors* (eg. Viagra) within the previous 24 hours
Question:
A patient is in *pulseless V-tach* (PEA). 2 shocks and 1 dose of epinephrine have been given.
Which drug should be given next?
Answer:
*Amiodarone 300 mg* (first dose)
Question:
What is the indication for the use of *magnesium* in cardiac arrest?
Answer:
Pulseless V-tach associated with *Torsades des pointes*
Question:
Which is one way to minimize interruptions in chest compressions during CPR?
Answer:
Continue CPR while the defibrillator charges
