Ever wonder when you would use a 14G IV vs a 16G IV?I LOVE starting IVs. Ā Nothing would get me more excited than having someone page me to help with a difficult stick.Seeing that flash and slowly advancing the catheter and getting a nice flush is one of the best feelings in the world (am I crazy).But you know what? Ā That confidence didnāt come overnight . . . nope. Ā In fact, I remember sweating bullets while trying to start an IV on the sweetest elderly lady. Ā She was clearly not enjoying having a new nurse ālearnā on her but obliged. Ā . Ā . the IV blew and I relented and called in my preceptor.
