Hello, So, I'm a new student. I was spiking and priming an IV bad and noticed some small bubble --- Is it concerning if I inserted the spike without filling the drip chamber halfway first, as in I ran the line first and then filled the chamber? I'm pretty sure I cleared out bubbles but would bubbles keep coming and hurt the patient? I'm such a paranoid student! Also, I got some patients blood on my arm - I didn't note any compromised skin but still...? I washed it off right away with soap and water.
