7 Integrated Renal Practice Questions Free Online FlashCards

When can a creatinine rise meet an acute kidney injury criterion?

A rise of at least $0.3\text{ mg/dL}$ within $48$ hours meets an acute kidney injury criterion; the case’s $0.5\text{ mg/dL}$ rise qualifies.

What is the priority with marked hyperkalemia and peaked T waves?

Treat the hyperkalemia as an emergency and stabilize the patient; peaked T waves indicate immediate risk.

How long must kidney abnormalities persist to establish chronic kidney disease?

Kidney abnormalities must persist for at least $3$ months to establish chronic kidney disease.

What is the immediate response to acute urinary retention with hydronephrosis?

Arrange prompt bladder drainage with a catheter to relieve retention, then evaluate the cause of the obstruction.

What can weight gain between hemodialysis sessions indicate?

Weight gain between hemodialysis sessions may largely reflect retained fluid; assess volume status rather than assuming the gain is body fat.

Which complications may occur in advanced chronic kidney disease?

CKD may be associated with anemia, metabolic acidosis, phosphate abnormalities, and hyperkalemia; assess severity and causes and individualize follow-up.

What do abdominal pain, fever, and cloudy peritoneal dialysis fluid suggest?

Abdominal pain, fever, and cloudy peritoneal dialysis fluid are concerning for peritonitis and require prompt assessment and treatment.

What initial approach fits suspected volume-depletion acute kidney injury?

Assess and correct likely volume depletion, review medicines that may worsen kidney injury, and monitor urine output and laboratory results.

What guides urgent dialysis assessment in acute kidney injury?

Urgently involve the renal team to assess for dialysis when dangerous electrolyte disturbance or fluid overload is present; a creatinine number alone does not determine the need.

How is persistent eGFR $38$ with UACR $450$ classified?

The results classify as CKD G3b A3: eGFR $38\text{ mL/min/1.73 m}^2$ is G3b, and UACR $450\text{ mg/g}$ is A3.

What should be done after relieving urinary retention?

Assess the cause of the obstruction as well as relieving the retention; the cause should not be left unexamined.

How should fluid management be adjusted for a hemodialysis patient?

Follow the prescribed target weight and individualized dialysis, sodium, and fluid plan with the dialysis team; recommendations vary by patient and treatment.
