I'm in my third semester of nursing school
.Tonight at clinical my patient had cellulitis caused by MRSA from a neglected PICC line. Go ahead and laugh at/berate me for my ignorance, but i was confused by her arm that seemed totally fine, but she had 3+ pitting edema that was hot to the touch. BP 90/50, HR in the 80's while on oxycodone, RR 14, temp 97F. Can someone tell me why the cellulitis is in her lower extremities instead of the arm the PICC line had been in?
