Renal Function Tests Quiz

Chronic renal failure may have no symptoms until the GFR falls below 15 ml/min.

Acute renal failure can only be caused by intrinsic damage to the kidney.

Post-renal acute renal failure may be due to cancer of the prostate or bladder.

In acute renal failure, the glomeruli filtration pressure is increased due to blockages.

Irreversible CRF can always be prevented with early intervention.

Serum creatinine is affected by diet, unlike urea.

High blood urea level above 80 mg/dl indicates normal renal function.

Low protein diets and dialysis can increase blood urea and serum creatinine levels.

Creatinine clearance is a useful measurement of Glomerular Filtration Rate (GFR).

Urea and creatinine clearances reflect the kidney's ability to filter blood per minute.

Creatinine estimation is not useful for assessing the severity and progress of renal failure in certain conditions.

The normal urea clearance is about 72 ml/min.

A plasma urea lowered by high protein diets is indicative of diminished glomerular function.

Cystatin C reflects glomerular filtration rate more accurately than creatinine.

If CRF is not treated by dialysis or transplant, it will result in death.

Oliguria is a biochemical change seen in chronic renal failure.

A minimum level of creatinine clearance needed to maintain life without renal dialysis is 10 ml/min.

Chronic renal failure can cause an increase in blood urea and plasma creatinine.

The urine concentration test is used to assess renal concentrating ability.

Metabolic alkalosis is common in chronic renal failure due to acid retention.

The urine concentration test is contraindicated in cases of low plasma urea.

Hypercalcemia is a common biochemical change in chronic renal failure.

Chronic renal failure (CRF) can develop over a period of days.

To determine Tm G, a glucose infusion is given to cause glucosurea.

Tg = (GFR * Pg) - (Ug * V) in the context of glucose reabsorption.

Acute renal failure (ARF) usually presents as a sudden improvement in renal function.

In Tm G, all filtered glucose will be excreted in the urine.
