Answer #1

Ans: A nurse should give priority for 24hours urine collection of Creatinine clearance test to estimate kidney function of elderly.

Rationale

Blood urea nitrogen test is elevated means there is may be problem with kidney or liver.

Serum creatinine: Even though it is regularly used test to estimate kidney function, for elderly it may be inaccurate. Because elderly has reduced muscle mass which may give incorrect serum creatinine results.

Renal ultrasound: It is best method to evaluate renal structures and its abnormality.

    2. Renal Function and Dialysis Metabolism of protein in your diet produces urea as a byproduct. The rate of urea production (r_u) depends on how much protein you eat and how big you are (measured by your body fluid volume, V). A realistic urea production rate for an average person (\/=40 L) is about r_u= 15 mg/min. Urea produced in the liver is rapidly distributed throughout the body's fluid volume V; the average urea concentration in the body's fluids is...
