Correcting Sodium for High Glucose Values

When you've got a high glucose, sometimes it's necessary to correct sodium.

You do this by taking the recorded glucose and, if it's higher than 199, add 1 to the recorded Sodium for every additional hundred glucose, to get the actual, corrected Sodium.

So for example, your patient's Glucose is 359, and recorded Sodium is 139. You add 2, since you're in the 300s. So your corrected Sodium is 141.
