19. A s s standing s s order s s of s s platelets s s was s s shipped s s to s s your s s facility s s by s s your s s supplier. s s It
s s was s s inadvertently ssleft s s in s s the s s corner of the s s department s s until s s discovered s s 36 s s hours
mm mm
s s later. s s What s s would s s the s s appropriate ssaction s s be ssfor s s the blood s s banker? mm
a. If s s the s s temperature s s in s s the s s box s s was s s 22 s s +/- s s 2°C s s and s s the s s platelet

s s inventory.
b. The s s platelets s s have s s fallen s s outside s s the s s supplier’s s s quality s s assurance.
s s The s s unit ssshould s s be s s discarded s s because s s the s s pH s s has s s probably
s s dropped s s too s s low s s and s s platelet ssactivation s s has s s been s s compromised.
