SW:  social worker, staff trained to assist the family in adjusting to illness, obtaining services, and works with other staff in the hospital to provide care

T:  temperature

TPO: Thyroid peroxidase is an enzyme normally found in the thyroid gland, TPO plays an important role in the production of thyroid hormones. A TPO test detects antibodies against TPO in the blood

TPR: temperature, pulse, respiration rate

TX:  treatment

WB:  whole blood

WBC:  white blood cell

Metric System Measurements

Regarding medications, the metric system is used in the hospital.  In liquid form milliliters to liters are used, for weight milligrams, grams, kilograms are used in the hospital as opposed to teaspoons or tablespoons or ounces.

Pharmacies can provide syringes or medicine cups that have both teaspoon and metric measurements on them to correctly measure liquid medications at home. If the hospital uses kilograms for weight 1 kilogram is equal to 2.2 pounds, but they often use a scale that has both pounds and kilograms on it.
