Casos clinicos de insuficiencia renal


1. In obstructive uropathy
A. The presence of polyuria rules out obstruction.
B. The absence of hydronephrosis on ultrasound examination rules out urinary tract obstruction.
C.Infection is a frequent complication.
D. Hypertension is uncommon.
E. Renal tubular acidosis (RTA), type IV, can occur.

2. Membranous nephropathy
A. May occur as a result of a systemicillness or be a primary (intrinsic) disorder
B. Merits an evaluation for malignancy when found in a patient older than 50 years
C. Infrequently improves without treatment
D. Does not recur inthe transplanted kidney
E. Is the most common cause of idiopathic nephrotic syndrome in adults

3. Features of magnesium depletion include
A. Hypokalemia
B. High serum parathyroid hormone levelsC. Prolongation of the PR and QT intervals
D. Amelioration of cardiac toxicity of cardiac glycosides
E. Can occur with aminoglycoside administration

4. Which of the following statementsis/are true about the renal hypoperfusion syndromes?
A. Salt avidity and hyperreninemia are usually observed.
B. Effective circulating volume has a greater effect on systemic BP than does reninsecretion in the setting of renal hypoperfusion.

C. Occlusive disease causes renal hypoperfusion, elevated renin secretion, and hypertension in the setting of a normal effective circulatingvolume.

D. Unilateral renal occlusive disease is not associated with azotemia if the contralateral kidney maintains normal function.

E. Nephrotoxic agents (cyclosporine, amphotericin B,radiocontrast dyes) can cause acute renal vasoconstriction with renal hypoperfusion, increased salt avidity, and azotemia.
