FAQ is an acronym for Frequently Asked Question. This page is intended to provide answers to common questions and solutions to common problems, along with some useful tips and tricks that are presented as questions.
| Q. |  |
On the TPN entry, the 24 hour rate is calculated from the base solution volume (for continuous infusion over 24 hours). Would it not be appropriate to divide the TOTAL volume (electrolytes, etc.) by 24 hours? |
 | | |
| A. | |
That is a point of contention for some pharmacists. I am from the school that uses the electrolytes as "overfill", to account for tube/pump priming, and to give a little cushion between bags, so you're not rushed to mixed a new bag if it runs in a little too fast, etc. Really, it's the same thing as using a pre-mixed IV, manufacturers routinely overfill IV bags by 5 to 10%. |

| Q. | |
The system requires patient height/weight before a new patient can be entered, in home care/LTC this info is not initially available. |
| | |
| A. | |
TPNassist© is a clinically-oriented program. You enter the patient data first, then create a nutrition Rx specifically for that patient, based on their estimated nutritional requirements. It's analogous to dosing drugs without knowing ht/wt, and giving every patient the same dose of gentamicin (80mg Q 8 hours). |
| | |
| Q. | |
My patient is bedridden and I cannot obtain his/her height, what should I do? |
| | |
| A. | |
Good question. A patient may also have scoliosis or severe contractions that prevent a true height measurement. There are (at least) three methods that may be used to estimate height when actual measurement is not possible: knee height, forearm length and demi-span. |
| | |
| Q. | |
Does TPNassist© interface with our Pharmacy Information System? |
| | |
| A. | |
TPNassist© may be interfaced with a PIS, using our open interface specification. Please contact your PIS vendor to request implementation. |
| | |
| Q. | |
What label size does TPNassist© require? |
| | |
| A. | |
TPNassist© requires labels which are 5" wide by 5" high (perf to perf). |
| | |
| Q. | |
We need to reinstall TPNassist© on our new computer, how do we transfer our current patient from our old computer? |
| | |
| A. | |
Step-by-step instructions for re-installing TPNassist©:

| Q. | |
I use Windows XP, some of the fields are missing, or difficult to read. |
| | |
| A. | |
Windows XP introduced the theme concept to Windows. Unfortunately the default theme in XP is the "Fisher Price" desktop with cartoon-like icons and a large Arial font. This font is too large for the TPNassist© screens. Change to the "Classic" theme, this uses a smaller font, and it also gives your screen a more professional look and feel. To select a different theme:

| Q. |
| When we print reports, the preview window is blank. The reports print out okay, the only problem is we are unable to preview them before printing. |
| |
|
| A. |
|
There is a known issue with dDoc on some video cards (driver problem) where the card is set to 24-bit or 32-bit color. This issue causes a *blank* preview window to display initially. Clicking on the window to resize the preview will display the previewed document. Also, clicking the print button will print the report just fine (it's a video-only problem). One work around for this is to set the color depth in the video display settings down to 16-bit color (this is a faster mode anyway, with very little difference in video quality). Otherwise, you may download the updated dDoc print engine here: |

|
| Q. | |
Error 0 "Unable to initialize the print/preview engine" |
| | |
| A. | |
This is caused by missing or improperly installed dDoc print preview engine. Please reinstall from the CD, or download from the web site. |
| | |
| Q. | |
Error 20 "Unanticipated error in the object ddoc.bas" |
| | |
| A. | |
This error too is caused by missing or improperly installed dDoc print preview engine. As above, please reinstall from the CD, or download from the web site. |
| | |
| Q. | |
Error 48 "File not found: ddoc32.dll" |
| | |
| A. | |
This error too is caused by missing or improperly installed dDoc print preview engine. As above, please reinstall from the CD, or download from the web site. |
| | |
| Q. | |
Error 91 "Object variable or with block variable not set" |
| | |
| A. | |
Error 91 is caused by a missing or incorrectly installed component required by TPNassist©.
If the error persists, please download the TPNassist component checker program. Clicking the "Register" button on the component checker usually fixes the problem. |
| | |
| Q. | |
Error 339 "Component 'DXDBGRID.DLL' or one of its dependencies is not correctly registered." |
| | |
| A. | |
DXDBGRID.DLL is a "helper" program used by TPNassist©. As stated in the error message, it is either missing or the Windows registry has "misplaced" it. You may download the missing file here: |
| | |
| Q. | |
Installation fails with error message "msdart32.dll is missing" when trying to install the program on my Windows XP system. |
| | |
| A. | |
We have found that some Windows XP Home systems were shipped without the latest data access components from Microsoft. The quickest solution is to copy the file yourself. You will need to be logged in with admin privileges. Next, get the DOS window on screen (you will find the DOS prompt shortcut in your Start menu). Then type the following lines at the DOS prompt, pressing enter after each line:
