Figure 1. Patient’s serum sodium level before, during, and after admission. This graph shows the level of the patient’s sodium levels throughout her hospital stay from day 1 to day 3. The patient was discharged on day 3 and was seen again on day 22 for an oncology follow-up. Despite aggressive management of her adrenal insufficiency, her sodium level did not correct appropriately from day 1 to day 3. After being given doxycycline for RMSF on day 3, her sodium level started to improve steadily and returned to normal by the time she was followed up in the oncology clinic on day 22. The normal sodium level of 135 mmol/L on day -8 is her sodium level 8 days prior to the admission obtained by the oncology clinic and used as the baseline for sodium level.
