In trying to gain employment as an RN, just having the certifications alone is not likely to be of much help. Particularly the ECG cert. However, having some significant experience actually working as a CNA or EMT would be helpful in that it demonstrates experience working with patients and would be a great opportunity to build references as well as network with employers that based on your performance as a CNA, tech, etc., would be more likely to hire you on as an RN rather than someone they can really only evaluate on paper and brief interview.
BLS/ACLS/PALS/ATLS, etc.... You should already be BLS certified as a student. All RNs should also be ACLS certified as well, but your employer will send you through that class when you get hired. I don't whether it is of much value in making yourself a more desirable candidate for employment. Who knows? Perhaps it may demonstrate that you show initiative. PALS/ATLS/TNCC are population specific and not worth spending money on if they aren't relevant to your position.
Again with the wound care/ostomy cert.- well it may demonstrate initiative, but I don't know to what degree it will really increase your value. And certain certs (wound/ostomy may even be one of them, I don't really know) require a certain amount of experience working as an RN with a certain population- not something a nursing student or newgrad would be eligible for- but those types of certs are very valuable and helpful in advancing your career.
These are just my thoughts, however, and I've never been involved in the hiring process. Your best source of information are the recruiters that work in HR. Get it straight from the source.
