Upon completion of the PAT, you'll be invited to participate in one of the upcoming 'assessment centers.' On the day of your assessment, you and your fellow applicants (perhaps a dozen or so per 'class') will perform in a four part evaluation (in no particular order): An online multiple choice...

IV Haldol is generally prohibited because the FDA does not approve its use for intravenous administration. Adverse effects of Haloperidol include: Torsades, elongated QT, tardive dyskinesia, neuroleptic malignant syndrome, et. al. The frequency and/or severity of such complications are...

Dimensional analysis practice (if you enjoy that sort of thing): A jewelry manufacturer is provided 50 lb blocks of silver. One of these blocks will be drawn into a silver wire that is 2.25mm in diameter. If its density measures 10.49 g/cm³, how many feet of wire can be obtained from the...

Robbins and Cotran is a great pathophys text, and a pretty easy read for anyone who's taken the basic bio, chem, and microbiology college courses. Bate's Guide to Physical Examination and History Taking is first-rate I have an enormous(!) copy of Tintinalli's Emergency Medicine; it's really...

Take a close look at her initial ECG morphology—awesome example of long QT syndrome triggering a Torsades event.

Im currently in paramedic school finishing up AAS degree. The students in my class are a pretty diverse bunch in terms of age and experience—for many, EMS will be their second career. As a college student, I was previously pursuing degrees in philosophy and sociology before my sudden transition...

Atropine will not affect the rate in a 3rd degree block, for better or worse. In the case of a CHB, the automaticity foci in the ventricles have assumed the role as pacemaker due to a conduction failure of the AV node. The SA and AV nodes are the only parts of the heart with parasympathetic...
