think blue. think positive!

salam.

just wanna share sumtin that i stumbled upon reading "endless" medical lecture notes. hak3

PRN = per re nata = as needed.

NPO = nil per os / non per os = nothing by mouth (those with acute appendicitis should be NPO pre-operatively, boleh bagi IV jek. antibiotics are most effective when given pre-opt coz they decrease post-opt infection and abscess formation)

lagi satu hint:

think blue, think positive!

in gram staining, gram positive bacteria stained blue.

see, i told ya to think positive kan tadi??? heh heh
