Exam 3: Renal Function

A patient showing symptoms of impaired renal function has a battery of tests performed.Results are: Serum creatinine: 2.0 mg/dL Urine creatinine: 150 mg/dL Serum osmolality: 270 mOsm Urine osmolality: 100 mOsm 24-hour urine volume: 2000 mL -Using the information provided,calculate the creatinine clearance.

Which of the following tests should be used to determine the ability of the kidneys to respond to filtrate osmolality?

The renal function that is most frequently the first affected by early renal disease is:

Normal functions of the kidney include all of the following except:

John White donates one of his two healthy kidneys to his twin brother.His glomerular filtration rate can be expected to:

The total renal plasma flow is approximately:

A patient showing symptoms of impaired renal function has a battery of tests performed.Results are: Serum creatinine: 2.0 mg/dL Urine creatinine: 150 mg/dL Serum osmolality: 270 mOsm Urine osmolality: 100 mOsm 24-hour urine volume: 2000 mL -Based on the information provided,calculate the free water clearance.

The primary chemical affected by the renin-angiotensin-aldosterone system is:

Water is passively reabsorbed in all parts of the nephron except the:

A 12-hour urine specimen with a volume of 360 mL is collected for a creatinine clearance.What is the volume (V)used to calculate the clearance?

Total acidity of a urine specimen is a combination of:

The enzyme renin is produced by the kidney:

A free water clearance of -2.5 could be indicative of:

Given the following laboratory data,calculate the free water clearance: Volume = 2800 mL/24 hour; Urine Osmo = 1200 mOsm,Plasma Osmo = 400 mOsm

Following a 2-hour infusion of p-aminohippuric acid (PAH),during which 200 mL of urine is collected,the urine PAH is 260 mg/dL,and the patient's plasma PAH is 0.8 mg/dL.Calculate the renal plasma volume.

Following injection of ADH,a patient has a serum osmolality of 290 mOsm and a urine osmolality of 450 mOsm.The patient:

The filtrate leaving the ascending loop of Henle is highly concentrated.

All of the following are endogenous clearance test substances except:

All of the following substances are reabsorbed from the glomerular filtrate by active transport except:

Hydrogen ions are filtered by the glomerulus and reabsorbed and secreted by the renal tubules.
