A 32 yr old male limps into the emergency department with complaints of general malaise with severe myalgias and arthralgias. He had run the Boston marathon two days ago and began feeling sick yesterday with headache, myalgias, nausea and vomiting.
His vitals signs are normal, but he appears clinically dehydrated and does describe a decrease in urine output over the past 12 hours. He appears very uncomfortable and you begin IV rehydration and decide to check his electrolytes.
The urine is dipped in the ED:
1. What additional labs should be ordered?
2. What diagnosis should you be concerned about?
3. What is the treatment?
4. What are the possible complications?
