D. platelets

E. blood clot

Your response:
plasma, serum, blood clot
Correct response:
serum, blood clot
Rationale: A centrifuged sample in a red top tube will have a liquid portion at the top and a solid
portion on the bottom. Since the red top contains no anticoagulant, the blood will clot. This
means the top liquid portion is serum and the bottom portion is the blood clot. Conversely,
centrifugation of an anticoagulated specimen will have plasma as the top liquid part of whole
blood, and red cells, white cells and platelets on bottom (no blood clot forms because the
specimen has anticoagulant).
The physician’s office sets aside Monday afternoons for high school sports physicals. This is an
example of which method of scheduling?

A. single-booking

B. double-booking

C. clustering

D. streaming wave

Your response:
streaming wave
Correct response:
clustering
Rationale: Clustering is a method of grouping or categorizing similar type appointments. The
best type of scheduling to accommodate unforeseen situations is wave scheduling. Wave
scheduling allows for a group of patients to be assigned to appointment times at the beginning of
each other. Double booking is also typically used when only one practitioner is available;
multiple patients are scheduled for the same time. Single booking is when each patient has a
specific time slot. Single-booking, double-booking and streaming wave would not be used for
efficiency in this type of situation.
