Dose Calculator screen

The Dose Calculator screen displays with the following:

•	Medication Name: This field displays the Item Master Description for the ordered medication.

•	Dose: Enter the formula in mg/kg that will be used to calculate the dose. The default unit is mg/kg/DOSE if the frequency is X1 or PRN and mg/kg/day for all other frequencies.

•	Frequency: This field will default to the frequency predefined on the item. Other options include:

▪	The magnifying glass icon may be selected to choose from the frequency table.

▪	The drop-down menu may be used to select one of the acceptable frequencies available on the item.

•	Concentration: This field displays the amount of medication per volume provided by Truven® and is based on the NDC number on page 1 of Pharmacy Information.

•	Rounding Option: This field defaults to a whole number. Other options are one decimal (x.x) place and two decimal (x.xx) places.

•	The Administer Dose and Administer Amount fields will display the calculated dosage/unit of the medication.

If the Administer Amount is less than zero, a message will display, "Administer amount must be greater than 0." In this case, the Rounding Option may be adjusted to display more digits to the right of the decimal point.

The Override Administer Dose field defaults to blank and may be edited to enter a different dose from the calculated Administer Dose field above. The dose value may be entered in MG with the format xxxxx.xxxx in numeric characters.

The Formulas section will display the formula that is being used to calculate the dose. The Formula box will change based on the selected units from the drop-down.
