an increase in glomerular filtration rate [GFR]. Explanation: The client's increase in blood glucose results in an increase in blood flow and GFR. These increases allow sodium excretion to be maintained at a near-normal level while increasing the excretion of the waste products of protein metabolism, such as urea. The same mechanism is thought to explain the large increases in renal blood flow and GFR that occur with high blood glucose levels in persons with uncontrolled diabetes mellitus.

AKI 4 phases

onset phase: tubular injury is induced oliguric phase: GFR falls, nitrogenous wastes accumulate, and urine output decreases diuretic phase: the kidneys try to heal and urine output increases recovery phase: tubular edema resolves and renal function improves. During recovery, there is normalization of fluid and electrolyte balance.

The initiating event in the development of nephrotic syndrome is a derangement in the glomerular membrane that causes increased permeability to which substance?

plasma proteins

An 86-year-old client is being treated for dehydration and hyponatremia after curtailing fluid intake to prevent urinary incontinence. Given these findings, the nurse recognizes that this client is likely in what phase of acute kidney injury?

prerenal

Which component of glomerular filtrate can passively cross the tubular epithelial cell membrane?

urea
