Take a look at some basic labs below.
What’s the next best test to diagnose the etiology of this patient’s presentation (choose 1!)?
Not the best test here, we don’t evidence of nephritic syndrome or immune complex mediated disease. Try again!
Ouch! Not a good idea here. Pick again!
24 hour urine collection for creatinine clearance measurement
This test is helpful in patient’s in whom estimated glomerular filtration rate (GFR) calculations may be inaccurate. A more accurate GFR value won’t help us right now. Try again!
Urinalysis and urine electrolytes
Excellent! Here they are:
Position emission tomography (PET) scan
Though this test may be help to evaluate for metastatic disease in this patient, there is a better test to diagnose the etiology of his current presentation. Pick again!
It’s time to lock in your final diagnosis below. Pick one!
Surreptitious laxative use
Type 1 RTA
Type 2 RTA
Type 4 RTA
Surreptitious diuretic use
Ethylene glycol poisoning
Vomiting due to chemotherapy
Almost there – let’s finish up this case!
