A) National Fire Protection Association (NFPA)
B) Joint Commission (JC)
C) Centers for Disease Control and Prevention (CDC)
D) OSHA

2. Creatinine clearance tests are utilized to estimate the glomerular function of the kidney. The creatitine clearance calculation is defined as the volume of plasma that is cleared of creatinine by the kidney per unit of time and uses the following formula:
creatinine clearance = Urine creatinine conc x Volume / Plamsa creatinine conc Creatinine clearance measurements have a recommended specimen requirement = 24-hour urine collection.
Which of the following tests would be useful in the assessment of glomerular filtration:

A) 24 hour urine protein
B) Creatinine clearance
C) PSP test
D) Urea clearance

3. Plasma concentrations of creatinine are used to assess renal function. Creatinine clearance is based on the serum creatinine level and is used to measure glomerular filtration rate, or GFR.
An increased serum level of which of the following analytes is MOST commonly associated with decreased glomerular filtration?

A) Glucose
B) Ammonia
C) Uric acid
D) Urea
E) Creatinine

4. Anything that can cause significant turbidity in a blood sample, such as high leukocyte count or lipemia can potentially interfere with the accuracy of a spectrophotometric hemoglobin assay.
Hematology
Which of the following may interfere with the accurate measurement of hemoglobin:

A) Leukocytosis and lipemia
B) Heparin
C) Leukocytosis
D) EDTA

5. The primary mechanism responsible for glomerular filtration is:

A) Concentration of blood components
B) Osmotic gradient
C) Rate of blood flow through the kidneys
D) Hydrostatic differential in glomerular tufts
