Today we had our second exam of the semester. The very first question was about the chain of infection:
We have been taught that this "chain" is like a cycle that can begin or end at any point
Anyway... The question was (multiple choice) Which of these is the proper sequence for the chain of infection?
A. (something wrong)
B. (wrong order)
C. Susceptible Host; Causative Agent; Reservoir; Portal of Exit; Mode of Transmission; Portal of Entry
D. Causative Agent; Reservoir; Portal of Exit; Mode of Transmission; Portal of Entry; Susceptible Host
Well, I wound up getting the "correct" answer (which they claim was "D") but it still really bothers me.
I said to my instructor while taking the test "these are both correct" to which she replied "well, you'll just have to use your critical thinking skills." :angryfire
Using my critical thinking skills I decided that they usually began with the causative agent when listing them. But I did still spend about 15 minutes on that question. I was sure that "D" must have the wrong order or something and that they wanted to make sure that we understood that the chain could begin or end at any point.
After the test was over, I complained about that question again. My instructor said that "D" was "more right" because "we treat sick people, so you want to trace it back to the causative agent."
Which didn't make a whole lot of sense to me. I told her that I didn't think that option C was any "less right" since prevention is stressed to us, you would want to break the chain at the susceptible host.
I went back to work and complained about this poorly worded question and I heard from another nurse that I needed to use my "critical thinking skills." :angryfire
I am sure that she thought I was just whining and wanted to weasel another point out of the test, but that is not
the point! I did
answer it "correctly" - I am just frustrated with the fact that neither answer was better than the other! Especially when they reinforced to us the fact that it can begin or end at any point!
IF answer "D" was in fact a "better" answer, could somebody explain to me how it is?
Thank you for letting me rant.
