Question

Covid-19 patients may develop acute pulmonary edema (fluid retention in the lungs), and furosemide is often used to treat it. 

Another potential complication of covid-19 is acute kidney damage. Possible causes include hypoxia, blood clots and inflammation. To evaluate a patient for kidney damage, a medical team took blood samples and placed a catheter to collect urine for 24 hrs.

Here are some results:

  • Plasma creatinine: 50 mg/100 mL plasma
  • Urine creatinine: 40.8 mg/mL urine
  • Urine production: 1.5 L in 24 hr

 

1. What was the patient's creatinine clearance in mL/min? (Creatinine clearance = excretion rate of creatinine/plasma concentration creatinine). Show your work.
