Question:

Serum bio markers of renal function

Answer:

BMP- includes serum glucose, electrolytes, and metabolic waste products

CMP - includes BMP test plus measurements of liver function and blood proteins.

Question:

Serum BUN

Answer:

6-20mg/dL 1 / 4

Question:

Serum Creatinine

Answer:

About 0.6-1.2 mg/dL

0.7-1.3mg/dL in males 0.5-1.1mg/dL in females

Question:

BUN/creatinine ratio

Answer:

10:1-20:1

>30:1 indicative of UGIb

Low ratio indicative of LGIB

• / 4

Question:

Renal Function Tests

Answer:

Urinalysis and microscopy (urine examination) Electrolytes and metabolic waste (serum chemistry) Serum chloride and carbon dioxide (acid - base balance) Urine concentration and dilution (tubular function) Filtration of functioning nephrons (glomerular filtration)

Question:

Urine dipstick/urinalysis

Answer:

Differentiating etiology of urinary symptomology (i.e. dysuria, polyuria, hematuria, etc.) in conjunction with P. E.

Question:

Urine microscopy

Answer:

Urine is centrifuged to cause sediment to precipitate. This sediment is then resuspended in a small volume of urine and put onto a glass slide for analysis to visualize cells, casts, crystals.Casts are highly suggestive of renal disease. 3 / 4

Question:

blood urea nitrogen (BUN)

Answer:

10-20 mg/dL Derived from breakdown of dietary proteins that are removed by kidneys.Rough index of glomerular function.Less reliable than creatinine in estimating kidney function.

Question:

What causes an increase in BUN?

Answer:

Impaired renal function, CHF due to decreased renal perfusion, salt and water, depletion, shock, G.I. hemorrhage, acute MI, stress, exercise, excessive protein intake

Question:

What causes a decrease in BUN?

Answer:

Liver failure, acromegaly, malnutrition, anabolic, steroids, over hydration, mature, absorption, syndrome of inappropriate antidiuretic hormone release

(SIADH).
