Some medication labels or inserts will provide more than one volume of diluent to use for the purpose of mixing different concentrations of the medication. Safety: It is always your responsibility to read the label and accompanying insert to determine the type and volume of diluent to use for reconstitution and the strength of the medication once it has been reconstituted. Vials A vial is a glass or plastic container of medication with a rubber stopper that must be punctured with a needle for medication removal (Fig. 37.10). If the label or insert indicates that the rubber stopper is designed for use with needleless systems, a needleless piercing device may be used in place of a needle MULTIPLE-DOSE VERSUS SINGLE-DOSE VIALS. Vials of parenteral solutions may be labeled as single-dose or single-use as well as multiple-dose or multiple-use vials. All multiple-dose vials contain bacteriostatic preservatives that reduce the risk of microorganism growth, while the single- dose vials do not. Safety: Avoid using single-dose vials more than once. Upon opening a multiple- dose vial, write the date, time, and your initials on the label. Some medications are good for only 24 hours; others vary in the length of time for which the drug may safely be used after opening. WITHDRAWING MEDICATION FROM A VIAL. Wash your hands before handling medication and supplies. Remove the plastic cap from the top of the vial and then wipe the rubber stopper of the vial with an alcohol wipe. Using two hands, remove the needle cover from the needle attached to your syringe and lay the cover down or stand it in a needle-recapping device. Hold the syringe in your nondominant hand, and use your dominant hand to grasp the plunger, holding it only by the flange. Pull the plunger back, filling the syringe reservoir with air equal to the amount of solution to be drawn up. For example, if you are to draw up 1.7 mL of medication, pull back on the plunger to fill the syringe reservoir with 1.7 mL of air. With the needle, pierce the rubber stopper of the medication vial at a 90-degree angle, allowing the pointed tip (the long side of the bevel) to enter the stopper first. Keep the needle tip above the fluid level and slowly inject the air from the syringe into the air space above the medication in the vial (Fig. 37.12). This slightly pressurizes the vial so that the medication can be drawn out easily. Safety: Do not inject air directly into the medication; doing so may introduce bubbles that will take up some of the space in the syringe and prevent you from drawing an exact dose of medication. After instilling the air into the vial, leave the needle inserted into the vial; invert both the vial and the syringe and carefully draw up the appropriate volume of medication by slowly pulling the plunger

back. Safety: Be certain to maintain sterility of the entire needle and the plunger that enters into the syringe barrel. Draw up the exact amount and inspect the syringe carefully for bubbles. If bubbles

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
