Quiz :Which of the following is not a standard method for measuring the
specific gravity of urine:
A. Urine reagent strips
B. Osmolality
C. Refractometry
D. Hydrometry - Answer :B. Osmolality
Osmolality is dependent on the number of particles of solute in a unit of
solution and is often measured by freezing point depression. Specific gravity is
usually directly related to osmolality, but is more easily measured. It provides a
rough measure of the urine concentration power of the kidney. The other
methods are used to measure specific gravity in urine samples.

Quiz :Which of the following are indicators of sepsis? (more than one is
correct)
A. Erythrocytosis
B. Increased heart rate
C. Leukocytosis
D. Increased body temperature - Answer :B. Increased heart rate
C. Leukocytosis
D. Increased body temperature
Sepsis results in an immune response by the body.
This response includes increasing body temperature and leukocytes in order to
help fight off the infection, and increased heart rate in order to get more blood
and oxygen to the tissues. Erythrocytosis is not part of the immune response.
Quiz :A traveler is being evaluated at a local hospital for gastrointestinal pain,
fever and diarrhea. The patient has recently returned from a month-long visit
to South Asia. The patient has no recent history of sexual activity of IV drug use
but did describe conditions of poor sanitation where they were visiting. If liver
function test results were elevated and bilirubinuria was noted, which of the
following would be the next logical test to oder?
A: ELISA for HBsAg
B. Recombinant Immunoblot Assay (RIBA) for Hep C
C. Western Blot test for HIV
D. ELISA for Hep A antigens in the stool - Answer :Hep B, C, and HIV are spread
primarily through sexual contact or IV drug use and needle sharing. While it is
possible to contact these viruses through other means, the patient history of
