(3) When measuring U**-**100 insulin (100 units per ml) in a 1 ml tuberculin

syringe, the number of units ordered will always equal an equivalent number of

hundredths of a milliliter. Therefore, to measure 16 units of U**-**100 insulin, measure to

the 0.16 ml mark on the tuberculin syringe. Be sure to use the cc scale on the syringe.

e. **Calculation of Medication Based on Body Weight. **Medication doses are

often based on the patient's body weight, especially with infants and children. Although

this is primarily a professional responsibility, you may use the manufacturer's

recommendations to determine if a prescribed dose is a reasonable dose to administer.
