level questions: Level 3 (Needles to Vials)

Question	Answer
the smallest needles have a gauge of __, the largest needles have a gauge of __.	27, 13
corresponds to the diameter of a needle bore	Gauge
The LARGER the gauge a. the smaller the needle bore. b. the larger the needle bore.	a. THE SMALLER THE NEEDLE BORE.
Length: the needle shaft is measured in inches and usually ranges from __ inches	3/8 to 3 ½ inches.
Components of a simple needle:	1 Hub 2 Shaft
ATTACHED THE NEEDLE TO THE SYRINGE and is often color-coded to correspond to a specific gauge.	Hub
1 the tip of the needle __ is slanted to form a point. 2 The SLANT is called the __ 3 the POINT is called the __. 4 The OPPOSITE END OF THE SLANT is termed __	1 shaft 2 bevel 3 bevel tip 4 bevel heel
No part of the needle itself should be touched. Needles should be manipulated by their __ only. The protective cover should be left in place until the needle and/or syringe are ready to be used.	over-wrap and protective covers
1 A needle shaft is usually __ and is lubricated with a sterile __ coating. 2 - For this reason, needles should never be swabbed with __ Some needles have built in filters and are meant to be used with products requiring frequent such as drugs removed from a glass ampule.	1 metal, silicone 2 alcohol.
Composed entirely of glass and once broken (opened) BECOME OPEN-SYSTEM CONTAINERS	Ampules
Ampules - Since air or fluid may now pass freely in and out of the container, it is not necessary to replace the volume or fluid to be withdrawn with air. - Before an ampule is opened, any solution visible in the top portion (head) should be moved to the bottom (body) by swirling the ampule in an upright position, tapping the ampule with your finger or inverting the ampule and then quickly swinging it into an upright position.	.
Ampules To break an ampule properly, the head must be broken from the body of the ampule. To make the break properly, the ampule neck is cleansed with an alcohol swab and the swab should be left in place. To withdraw medication from an ampule, the ampule should be tilted and the bevel of the needle placed in the corner space (or shoulder) near the opening. To withdraw the solution, either use a filter needle and change to a regular needle BEFORE expelling the contents.	.
Ampules Usually the medication is withdrawn from the ampule with a regular needle and then the needle is changed to a filter needle before pushing drug out of the syringe.	.
Is a glass or plastic container with a RUBBER STOPPER SECURED TO ITS TOP, usually by an aluminum cover. They are USED TO HOLD POWDERS AND LIQUIDS.	Vials
VIALS 1 The rubber stopper is usually protected by a __ 2 Most protective covers do not guarantee sterility of the rubber stopper; therefore, before the stopper is penetrated, it must be swabbed with __ and allowed to dry.	. 1 flip-top cap or aluminum cover. 2) 70% isopropyl alcohol
VIALS Swabbing helps achieve sterility in two ways:	1 the alcohol acts as a DISINFECTING AGENT 2 the physical act of swabbing in one direction REMOVES PARTICLES.
Vials are __ since air or fluid cannot pass freely in or out of them.	closed-system containers
Vials In most cases, air pressure inside the vial is similar to that of room air. In order to prevent the formation of a vacuum inside the vial (less pressure inside the vial than room air) the used should normalize pressure by first injecting into the vial a volume of air equal to the volume of fluid that is going to be withdrawn. If the drug is in powdered form, it has to be reconstituted. Inject the desired volume of sterile diluting solution (the diluent), such as sterile water for injection, into the vial containing the powdered drug.	.
Vials with drugs in solution are classified as __	multiple-dose (also called multiple use) or single-dose.
1 contain a SMALL AMOUNT OF A PRESERVATIVE agent, added to retard the growth of bacteria or other organisms that inadvertently contaminate a product. 2 have NO PRESERVATIVE and are intended to be USED ONE TIME ONLY. Once a vial is entered with a needle, it should be discarded.	1 Multiple-dose vials 2 Single-dose vials
