____________________________________________________
Lab equipment and other inanimate objects serve as what in the chain of
infection
Fomites
The chain of infection includes
Infectious agent, Reservoir, portal of exit, means of transmittion, portal of entry,
susceptible host
Why will a supervisor be concerned about a cut in your hand
Provides a point of entry
What I centrifuging an uncapped tube of urine most likely to produce?
Aresols
Which guidelines tell laboratory personnel to consider all patients as possible
carriers of blood-borne pathogens?
Standard precautions
When does the CDC recommend that universal precautions be followed?
With every patient
,What is the approx. number of nephrons contained in each kidney?
1-1 1/2 million
What is the order of blood flow through the nephron?
Afferent arteriole, efferent arteriole. paratubular capillaries, vesa recta
The total renal blood flow is
1200mL per min
Describe glomerular filtrate
Protein-free ultra filtrate of plasma
Clearance tests used to determine the glomerular filtration rate must measure
what kind of substance
neither reabsorbed or secreted by the tubules
The most routinely used laboratory method for measuring the GFR is
Estimated GFR
What is he renal function that is most frequently the first affected by early renal
disease?
Tubular reabsorption
Why is measurement of urine osmolality is a more accurate measure of renal
concentrating ability than specific gravity?
Osmolality is influenced by both small and large particles
The pigment responsible for a pink precipitate in refrigerated urine
,Uroerythrin
The addition of dilute acetic acid to a cloudy urine specimen will dissolve
Amorphous phosphate
Slightly warming a turbid urine specimen may dissolve
Amorphous urates
The SG of urine is directly proportional to
dissolved solids
Bacterial decomposition of urea produces urine that has an odor resembling
ammonia
Are clear red urine and red plasma associated with myoglobinuria
False
Cause of prerenal proteinuria
Multiple myloma
When using the reagent strip micro albumin method, false-negative results may
occur in the presence of
Highly dilute urine
The albumin to creatinine ratio may be elevated in patients whose urine
contains
Glucose
Galactose will react with
, Clinitest but not chemstrip
The recommend centrifugation setting for preparation of the urine sediment is
RCF of 400 for 5 minutes
The number of fields that should be examined when quantitating urinary
sediments constituents is
10
The purpose of including glucose as a significant chemical parameter by a
laboratory that performs macroscopic screening is
to check for Candida Albicans
To detect the presence of casts, the sediment is examined using
Low-power, reduced light
Identification of oval fat bodies can be verified using
Polarized light
The presence of crenated RBCs in the urine sediment is associated with
Hypersthenuria
Dilute alkaline urine should be examined carefully for the presence of
Ghost cells
Urine sediments containing increased WBCs should be observed closely for the
presence of
Bacteria
