Unfortunately I don't have any fancy way of remembering these values;
you just have to commit them to memory. It will be worth it because you
will use this information everyday.

Nursing Tips:
Remember abnormal lab values require further assessment
May indicate infection, toxicity, or certain medications not being therapeutic
