Unless you're real good at interpreting arrhythmias you're not going to do well in ACLS and PALS. BLS for sure, (isn't that required for nursing school
?), but I would wait until you learn rhythm strips, which will hopefully be part of your ICU classes during your orientation. There's the added bonus they will pay for it and might even teach it.
Rhythm strips are part of the test in ACLS. It's nice to be ambitious, but there's no harm in waiting. Most places don't require them of new grads.
opps, I see someone else said the same thing. My point being this is all hard to do while you're taking other classes, and you want to do ACLS and rhythms justice.
Good luck in whatever you decide.
