Here is a summary of the technique that we've developed based on several sources, the main one being the one listed below. Perhaps you can just share a link to this thread with the nurses so that they have the patient experiences, this summary, and an additional reference all in one place..
The technique is as follows:
- Attach a fresh needle (4-6 millimeter) to syringe with prepared medication
- Do not purge needle (air in needle)
- Draw the Velcade into the syringe for a maximum volume of 2 ml medication per site for subcutaneous injection
- Pull 0.5-1.0 ml air into syringe, so that the is behind the drug when the syringe is inverted
- Using the index finger and thumb, "pinch an inch" in the selected site for injection; avoid pinching the underlying muscle
- Invert syringe, inject at 90 degree angle for needles 4-6 millimeter, and at 45 degree angle for needles 8 millimeters or longer, including air behind the drug, which effectively seals the drug into the subcutaneous fat (preventing it from leaking into the surrounding tissue)
- Remove needle promptly
- Apply gentle pressure to site.

which also has a helpful table summarizing the technique and related information. However, additional information from other sources also has been used to make the summary above as clear as possible.
Just tell 'em you have a friend who's a nurse.
