16. A 6-year-old girl is brought to the physician because of a 4-week history of headache, fatigue, and decreased appetite. During this period, she has had nausea and vomiting. At the age of 4 years, she was diagnosed with poststreptococcal glomerulonephritis. She is at the 15th percentile for height and the 10th percentile for weight. Examination shows no abnormalities. Her serum urea nitrogen (BUN) level is 50 mg/dL. Which of the following is most likely to limit progression of this patient's renal failure?

A
) Increased potassium and sodium bicarbonate intake

B
) Decreased sodium and daily calorie intake

C
) Low-protein diet

D
) Strict fluid restriction

E
) Dialysis

ccc

explanation pls

A low-protein diet initially reduces the single-nephron glomerular filtration rate but subsequently slows the progression of renal disease. Since this patient has underlying renal disorder, low protein diet places less stress on the kidneys.

i thought psgn so sodium restriction helps to improve kidney failure.but they ask rx of CRF.got it.
thanks cgoose

for sure

it seems to be dehydrate. what about D?
