KROK 1 2017 – Question 78 · KROK (Medicine) · Physiology
A man presents with glomerular filtration rate of 180 ml/min., while norm is 125±25 ml/min. The likely cause of it is the decreased:
- A. Hydrostatic blood pressure in the glomerular capillaries
- B. Effective filtration pressure
- C. Permeability of the renal filter
- D. Renal blood flow
- E. Plasma oncotic pressure
Hint
Filtration rate is above normal, so ask which of the listed decreases would actually raise it, and think about the forces that favour and oppose fluid movement across the glomerular filter.
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.
