3ий курс / English / test AKI, CKD (1)

Acute kidney injury and chronic kidney disease

1. The preferable method of assessing renal filtration function (glomerular filtration rate):

1. Rehberg test

2. MDRD

3. CKD-EPI

4. Cockcroft formula

2. Which of the following is a diagnostic criterion for CKD:

1.↓GFR < 90 ml/min/1,73 m² within > 3 months

2.↓GFR < 60 ml/min/1,73 m² within > 3 months

3.↓GFR < 90 ml/min/1,73 m² within >1 months

4.↓GFR < 60 ml/min/1,73 m² within>1 months

3. Normal range of GFR is as follows:

1. 40 – 60 ml/min

2. 80 – 120 ml/min

4. Which of the following is an indication for assessing albuminuria in patients with diabetes mellitus:

1. proteinuria >3.5 g/24 hours

2. proteinuria >1 g/24 hours

3. no proteinuria

5. AKI can be caused by:

1. Renal arteries thrombosis

2. Urinary tract obstruction

3. Chronic pyelonephritis

4. Cardiogenic shock

6. AKI is characterized with:

1. Decrease in urine gravity

2. GFR < 60 ml/min/1,73m² within > 3 months

3. Increase in serum creatinine > 26,5 mcmol/l within 48 hours

4. Diuresis <0,3 ml/kg/h for >24 hours or anuria > 12 hours

7. Which of the following can be used for GFR assessment:

1. urea clearance

2. creatinine clearance

3. uric acid clearance

4. potassium clearance

5. sodium clearance

8. 75 – year old patient:

History: 4 months ago creatinine level was 400 mcmol/l, GFR – 12 ml/min/1,73m²

Blood chemistry: creatinine – 480 mcmol/l, GFR – 9 ml/min/1,73m²

24 hour proteinuria – 600 mg

Urinalysis: leucocytes – 0-2 per HPF, specific gravity is 1006

Ultrasound: decreased kidney size (70х40 mm), parenchema – 10 mm

What’s the presumptive diagnosis?

1. AKI

2. Renal amiloidosis

3. CKD

4. Nephrotic syndrome

9. 60-year old patient with preserved kidney function, diabetes mellitus type 2, urolithiasis complains of nausea, vomiting, dyspnea, decreased amount of urine. These symptoms appeared after excretory urography.

Blood chemistry: creatinine 109→500 mcmol/l, GFR 63→3ml/мин/1,73m², potassium 6.5 mmol/l.

Ultrasound: normal kidney size.

What’s the presumptive diagnosis?

1. Acute nephritic syndrome

2. Nephrotic syndrome

3. AKI

4. CKD

5. Upper urinary tract infection

10. 55-year old patient with long history of chronic glomerulonephritis (latent course) complains of fatigue, nocturia, headache.

General assessment: pale skin, BP 170/110 mmHg

CBC: Hb – 103 g/l

Blood chemistry: creatinine – 200 ml/min/1,73m², GFR 33 ml/min.

Urinalysis: leucocytes – 0-1 per HPF, specific gravity is 1005, erythrocytes 8-10 per HPF.

Ultrasound: decreased kidney size.

What’s the presumptive diagnosis?

1. Acute nephritic syndrome

2. Nephrotic syndrome

3. AKI

4. CKD

5. Lower urinary tract infection
