It really aggravates me when I am
trying to study and actually read the review answers and I get something like
this horse squeeze:
“Laboratory
tests are ordered for two hospitalized patients. During the phlebotomy
procedure, the Vacutainer tubes drawn from these patients are mislabeled. One
of the patients receives a blood transfusion later that day. Within 1 hour
after the transfusion of RBCs begins, the patient becomes tachycardic and
hypotensive and passes pink-colored urine. Which of the following statements
best describes how this reaction is mediated?”
I had it
narrowed down between:
B)
Antibody-dependent cellular cytotoxicity by natural killer cells
D)
Complement-mediated lysis of RBCs
Needless to say I got it wrong,
and chose B, but that’s not what aggravates me, because I usually LEARN from
answering questions incorrectly. I proceed to the explanations and this is what
I get RE: answer B:
“…Natural killer cell lysis is
seen with antibody-mediated diseases.” You don’t say, Sherlock! Obviously I
should have known that the process was complement-mediated, but I thought
differently. C’est la vie, I can get
over that. I’m kvetching because that
is a completely USELESS statement. Yeah I’m making something out of nothing,
but it’s these “DUH!” circular statements that make me wonder how much the schmucks who wrote this got paid…
