According to USP <797>, appropriate alcohol swabs for the use in the IV room must be individually packaged and presaturated with sterile ___ IPA

Sterile water and normal saline

An IV technician most frequently uses these two solutions as diluents:

SDV (single dose vial) Single-dose vials (SDVs) that do not contain a preservative. The absence of a preservative in an SDV provides an ideal medium for the growth of microorganisms. Therefore, this type of vial is meant only for one-time use and should be discarded after puncturing the top and using the contents.

An ampule, a vial WITHOUT preservatives, and a prefilled syringe are all considred to be which type of container?

Straight draw

Drawing fluid into a syringe is referred to as a:

Six inches

How far inside of the hood must you work in order to maintain adequate sterile airflow and correct aseptic technique?

from NONSTERILE ingredients ø 0.2 µm or smaller ø Used to sterilize solutions that have been prepared using nonsterile ingredients. Filter is attached to the tip of a syringe containing the nonsterile fluid. ø A needle is attached to the other side of the filter, and the fluid is pushed through the sterilizing filter and into the receptacle such as an empty evacuated container (EEC)

Membrane filters are used to sterilize solutions that have been prepared:

sodium or dextrose

Most IV base solutions are made with varying concentrations of ___ mixed with sterile water

dilute parenteral medications in powder form Vented needle: a needle used to dilute powders that simultaneously vents air pressure out of the vial while injecting diluent into the vial

Technicians use vented needles primarily to:

Smallest syringe within which the total volume of the desired fluid will SAFELY fit

The best syringe choice is the:

Lumen

The hollow space of the needle through which fluid moves into or out of a syringe is referred to as the:

Critical site

The part of a supply item that includes any fluid-pathway surface or fluid-pathway opening that is at risk for contamination by touch or airflow interruption is referred to as the:

IV push use

The pre-filled syringes supplied by manufacturers are used in the hospital for:

Vented dispensing pin

This item is inserted into a vial or glass bottle and then attached to a syringe, thus allowing easy withdrawal of a large volume fluid while equalizing the pressure within the container

Syringe cap

This supply item is used as a precaution to allow the safe transport of a syringe to the nursing unit

Shadowing

This type of contamination involves anything that interrupts the airflow from the HEPA filter to a critical site supply item

Filter needle

This type of needle is used to remove particulate matter from a solution

1. helps to decrease the wastage that would result from the relatively short stability of mixed IVPBs. 2. personnel may return unused doses of medication to the pharmacy, where they are relabeled for use with other patients. Such reuse is possible because these systems are stable for up to 30 days, provided that the internal chamber has not been broken and the drug has not been mixed into the IVPB. 3. the nurse breaks a small, internal chamber located at the joint where the vial and IVPB are attached. This action opens the flow of fluid from the IVPB into the vial, which then allows the drug in the vial to mix with the fluid in the IVPB bag 4. This type of IVPB can be mixed just moments before the dose is required 5. This deferred mixing is helpful if the medication is not stable for long periods in its mixed form

What is an advantage of using a vial and bag system?

Clean air zone

What is another name for the direct compounding area?

25- 250 mL

What is the usual volume range for an IVPB solution?

At least six-inches inside the hood

When working in a hood, an IV technician must open the outer package of a supply item ____ to maintain aseptic technique

bevel

Which component of a needle is closest to the needle tip?

small volume (25-250 mL), with additives, run intermittently

Which description reflects the qualities of an IVPB (IV Piggyback) solution?

16 g The size of the gauge corresponds *conversely* to the size of the lumen: the larger the gauge number, the smaller the lumen, and, consequently, the smaller the hole that the needle makes. The smaller the gauge number, the larger the lumen and, consequently, the larger the hole that the needle makes. E.g. a 25-gauge needle makes a very small hole, whereas a 16-gauge needle makes a much larger hole.

Which gauge represents the largest needle opening?

Accidentally touching a syringe tip to your sterile, gloved finger

Which scenario would result in touch contamination?

Vials

___ are sealed, sterile containers made of plastic or glass, with a rubber top through which the IV technician draws fluid
