Front (Question)

What are the 3 categories of Azotemia?

Back (Answer)

Pre-renal Azotemia Renal Azotemia Post-renal Azotemia

Front (Question)

This category reduces blood flow to the kidneys, increase protein catabolism or degradation and increase urea w/o an increase in creatinine.

Back (Answer)

Pre-renal Azotemia

Front (Question)

What happens if less urea is excreted?

Back (Answer)

More urea is retained in the blood

Front (Question)

Under Renal Azotemia, what is the problem?

Back (Answer)

There is a defect in the glomerular filtration rate and there are lesions along renal parenchyma.

Front (Question)

What happens in the Post-renal azotemia?

Back (Answer)

Obstruction of Urine flow

Front (Question)

What is the normal BUN:CREATININE RATIO?

Back (Answer)

10-20:1

Front (Question)

What is the other name of CREATININE?

Back (Answer)

Anhydride of creatine

Front (Question)

How is creatinine produced?

Back (Answer)

• Creatine loses water • Creatine phosphate loses phosphoric acid (dephosphorylation)

Front (Question)

What is the end product of muscle metabolism?

Back (Answer)

Creatinine

#10

Front (Question)

What can be used to assess the completeness of a 24-hr urine specimen since this is excreted at a constant rate?

Back (Answer)

Creatinine

#11

Front (Question)

The principal waste product of muscle metabolism is derived from?

Back (Answer)

Creatine

#12

Front (Question)

This is used as an accurate monitor of kidney function.

Back (Answer)

Creatinine

#13

Front (Question)

How is the formation of Creatine?

Back (Answer)

Transamination of Arginine and Lysine forming guanidinoacetic acid. As well as the methylation of guanidinoacetic acid.

#14

Front (Question)

What is the muscles’ energy source?

Back (Answer)

Creatine Phosphate

#15

Front (Question)

The Renal handling of Creatinine is via?

Back (Answer)

Glomerular filtration

#16

Front (Question)

What is done to obtain the value of creatinine?

Back (Answer)

apply Jaffe reaction to trichloroacetic acid filtrate of serum

#17

Front (Question)

What would be the product if Creatinine is reacted with Alkaline picrate?

Back (Answer)

Creatine picrate (red/yellow)

#18

Front (Question)

What is the composition of Alkaline picrate?

Back (Answer)

Picric acid + sodium hydroxide

#19

Front (Question)

What is the product measured under colorimetric: Jaffe’s reaction?

Back (Answer)

Red-orange complex known as Janovsky complex

#20

Front (Question)

At what wavelength is Janovsky complex measured?

Back (Answer)

490 - 505 nm

#21

Front (Question)

What is the preferred than the end point Jaffe reaction?

Back (Answer)

Kinetic Jaffe reaction

#22

Front (Question)

In this reaction, most interfering substances require longer time before contributing significantly to the absorbance which happens in the end point.

Back (Answer)

Kinetic Jaffe Reaction

#23

Front (Question)

This uses hydrated aluminum silicate to absorb interfering substances.

Back (Answer)

Lloyd’s reagent / Fuller’s earth

#24

Front (Question)

What is the absorbent that Lloyd’s reagent use?

Back (Answer)

Sodium Aluminum silicate
