What is considered a competitive step 1 score for EM residency?

Hell, I barely got 240 on Step I AND II put together. And yet, twice today, patients told me I was a good doc. Go figure.

Speaking of high potassiums, I had a great one last month. K of 8.7. Normal renal function. Na of 123. CC: general weakness.

Exaggerating a little? Passing score for the Steps is around 176, isn't it?

Our Path professor told us that serum Na+ < 120 is pathognomonic for siADH. Any thoughts?

Methinks he is wrong. Extreme psychogenic polydipsia.

No, not polydipsia. Polydipsia causes hyponatremia, but doesn't explain the hyperkalemia. Don't feel bad it you don't get it in a flash. I had to put the chart down, deal with the potassium, then come back to it before it hit me.
BTW, the rest of the routine bloodwork was normal (including bun and creatinine), the EKG had t waves that looked a bit peaked (in retrospect). Urine analysis was also normal, much to my surprise, as I expected an elderly patient with generalized weakness to have a UTI. I'll reserve the rest of the results until somebody comes up with the answer.
Exam was unremarkable except for generalized weakness evident on strength testing, and just appearing very tired.

Adrenal insufficiency? Go off their steroids?

Good thought. After kayexalate, insulin, glucose, and a neb treatment, it was the first thing I thought of too. The redraw was the same.did you repeat the labs? or check to see if it was hemolyzed? just a thought

Is this individual in early renal failure? BUN of 29 and creatinine of 1.7 are both elevated right? Or is that just decreased CO, due to early CHF? Just asking cause we covered azotemias last week.

Probably early renal failure was my guess. She was not clinically in CHF.
Anyway, with her lung mass, my presumptive diagnosis was Addison's Disease secondary to paraneoplastic syndrome.

Were they orthostatic?
Did they end up checking an AM cortisol or did they do a corticotropin stim test?
Did she get an ABG?
Urine pH? and urine lytes for Urine AG.
The IM side of me wants to know if she had a Type 4 RTA (hypoaldosterone associated non-gap acidosis)
