A 55-year-old woman presents to a physician’s clinic for a diabetes follow-up. She recently lost weight and believes the diabetes is ‘winding down’ because the urinary frequency has slowed down compared to when her diabetes was "at its worst". She had been poorly compliant with medications, but she is now asking if she can decrease her medications as she feels like her diabetes is improving. Due to the decrease in urinary frequency, the physician is interested in interrogating her renal function. Which substance can be used to most accurately assess the glomerular filtration rate (GFR) in this patient?
APara-aminohippurate (PAH)
BGlucose
CInulin
DUrea
ECreatinine
Which factor most strongly influences protein filtration at the glomerulus?
AElectrical charge
BMolecular size
CShape
DTemperature
A 45-year-old man presents with a 3-day history of right-sided flank pain due to a lodged ureteral stone. What changes would be expected to be seen at the level of glomerular filtration?
AIncrease in glomerular capillary oncotic pressure
BIncrease in Bowman's space oncotic pressure
CIncrease in filtration fraction
DIncrease in Bowman's space hydrostatic pressure
ENo change in filtration fraction
