KROK 1 2014 – Question 44 · KROK (Medicine) · Physiology
Urine analysis has shown high levels of protein and erythrocytes in urine. This can be caused by the following:
- A. Hydrostatic blood pressure in glomerular capillaries
- B. Renal filter permeability
- C. Effective filter pressure
- D. Hydrostatic primary urine pressure in capsule
- E. Oncotic pressure of blood plasma
Hint
Normally blood cells and large proteins stay in the blood, so ask which factor must have changed for them to cross into the urine, rather than which one merely changes how much fluid is formed.
The answer, the explanation and a note on every option are available once you log in. The account is free: topic tests, a mock exam, mistake review and statistics.
