BKAT ICU COMPREHENSIVE POST TEST
REVIEW 2026 QUESTIONS AND SOLUTIONS
◉ First degree block interpretation. Answer: looks like sinus rhythm
but the PR is longer than normal. there will be 1 p for every qrs, but
the PR interval will be greater than 0.20 sec
◉ Type 1 second degree block interpretation. Answer:
"Wenckebach"
"Longer, Longer... drop" prolonged PR intervals and the missing QRS
◉ Type 2 second degree block interpretation. Answer: PR interval is
constant...QRS is missing
"2 small p waves right after each other"
give atropine, dopamine, or epi to increase HR is symptomatic
bradycardic
◉ Third degree AV block interpretation. Answer: a strip of p-waves
laid independently over a strip of QRS complexes. Note that the p
wave doesn't conduct the QRS complex that follows it.
◉ A-flutter interpretation. Answer: abnormal p-waves that produce
a saw-tooth appearance
,◉ Failure to Capture interpreation. Answer: spike without a complex
◉ Failure to Pace interpretation. Answer: no pacemaker activity or
spike at the set rate on an ECG. usually caused by battery or circuit
failure, cracked or broken pacing leads, loose connections,
oversensing, or the pacing output is too low--->can lead to asystole
◉ Failure to Sense. Answer: undersensing: giving help when not
needed; spikes occur on the ECG where they shouldnt
◉ Pacemaker ECG rhythms. Answer: failure to capture: spike
without a p wave or QRS complex following it
failure to pace: no spike on ECG at the rate set
failure to sense:
spike when intrinsic activity already present (undersensing)
no spike when patient needs it
(oversensing)
◉ Which ventricular stimulus is dangerous. Answer: R on T
phenomenon
◉ Indications for a pacemaker?. Answer: symptomatic bradycardia
, higher AV blocks (2nd degree type 2 or Complete)
◉ what is not a treatment for higher degree AV blocks. Answer:
atropine
because of the impaired conduction through the AV node
◉ A-flutter happens because?. Answer: an irritable spot of the
atrium fires rapidly
◉ A-flutter can cause _______. Answer: an increase in ventricular rate
◉ A-flutter is treated by:. Answer: antiarrhythmics (cardizem, beta
blockers)
cardioversion
◉ What do you do if you notice a lethal rhythm on the monitor
(VT/VF)?. Answer: check the patient first
-establish unresponsiveness
call for help
-begin CPR if needed
◉ When defibrillating VT/VF use _____ joules for biphasic
defibrillator or _____ joules for monophasic.. Answer: 200
