Which is a likely cause of elevated blood urea nitrogen bun in a client?

Increased blood urea nitrogen (BUN) may be due to prerenal causes (cardiac decompensation, water depletion due to decreased intake and excessive loss, increased protein catabolism, and high protein diet), renal causes (acute glomerulonephritis, chronic nephritis, polycystic kidney disease, nephrosclerosis, and tubular ….

Which is the most common condition associated with the formation of renal calculi?

Calcium-containing stones Factors that promote the precipitation of oxalate crystals in the urine, such as primary hyperoxaluria, are associated with the development of calcium oxalate stones. The formation of calcium phosphate stones is associated with conditions such as hyperparathyroidism and renal tubular acidosis.

25%In humans, the kidneys together receive roughly 25% of cardiac output, amounting to 1.2 – 1.3 L/min in a 70-kg adult male. It passes about 94% to the cortex. RBF is closely related to renal plasma flow (RPF), which is the volume of blood plasma delivered to the kidneys per unit time.

What is the normal range for eGFR in blood tests?

A normal eGFR for adults is greater than 90 mL/min/1.73m2, according to the National Kidney Foundation. (Clinical laboratories that use the MDRD equation to calculate eGFR will only report actual values that are less than 60 mL/min/1.73m2 because MDRD works best for estimating reduced kidney function.
