What is the standard medical abbreviation for subcutaneous injection?  SQ, SC, Subq  
Where is the medicine deposited when you give a subcutaneous injection?  in the fatty layer of tissue beneath the skin and above the muscle  
What is the standard medical abbreviation for intramuscular injection?  IM  
Where is the medicine deposited when you give an intramuscular injection?  into the layers of the muscle  
List three classifications of medications that might be given via intramuscular injections  analgesics; antiemetics; antibiotics; antipsychotics; nonsteroidal anti-inflammatory (Toradol);anticholinergics  
What standard medical abbreviations are used medications administered intravenously  IV  
List two types of medication given via subcutaneous injections  insulin; heparin; calcitonin  
Where does the medication go when intravenous medications are administered?  directly into the bloodstream  
List injection routes in order from the most rapidly absorbed to the least rapidly absorbed.  IV, IM, SC, ID  
List three factors that influence the selection of needle length and gauge. Explain the significance of each.  type of medication to be injected\u2014how deeply it needs to be injected; type of injection to be given\u2014intradermal, subcutaneous, or intramuscular; size of the patient\u2014amount of adipose tissue to inject into or for needle to penetrate past; consistency of me  
What range of needle lengths and gauges would you use for a subcutaneous injection?  1/2 to Scinch needles; 25, 26, 27 gauges  
What range of needle lengths and gauges would you use for an intramuscular injection?  1, 1 1/2, or 2-inch needles; 20, 21, 22 gauges  
What are the two most common sizes of syringes used for  1 cc and 3 cc  
What is the difference between an insulin syringe and a tuberculin syringe?  An insulin syringe is marked in units, usually 100 units per 1 cc. A tuberculin syringe is calibrated in tenths of a cc and equals 1 cc.  
What is a cartridge syringe (Tubex, Carpuject)?  A cartridge syringe is a pre-filled glass syringe barrel with needle attached. It loads into a reusable plastic or metal holder.  
What is the difference between a vial and an ampule?  An ampule is a glass container with a narrow neck, containing a single dose of medication. The top must be broken at the neck to open the ampule. A vial is a small glass bottle that may contain one or more doses of a medication. It is sealed with a remova  
How is a pre-fillea cartridge loaded into a cartridge syringe?  The pre-filled cartridge drops into the metal or plastic cartridge syringe and screws into place. The plastic or metal plunger screws into the top of the cartridge.  
What type of needle should be used when drawing medication , ^TA. from an ampule into a syringe?  a filter needle to filter out any tiny shards of glass left from breaking the top of the ampule  
Under what circumstances would yow change the needle after drawing up a medication for injection?  the gauge is large enough to cause a core of rubber to be cut out of the stopper on; a vial the needle has touched a different medication, such as when two medicines are; mixed in same syringe if needle penetrates a rubber stopper on vial more than once  
How do you know if a medication for injection is too old to USe?  check the expiration date on the ampule or vial  
What is the purpose of injecting air into the medication vial before drawing up the medication?  to displace the amount of medication needed with air, preventing a vacuum  
What is the Z-track method for giving intramuscular injections?  a method designed to keep irritating medicines from being dragged through the subcutaneous tissue as the needle enters or exits the muscle  
Under what circumstances would you use the Z-track method?  when the medication is irritating to the subcutaneous tissue  
What is the purpose of creating an airlock when drawing up medication for Z-track injection?  the airlock pushes the medicine completely through the needle and into the muscle  
List four-ractors to assess when choosing a site for injection  amount and type of medication to be injected; size of patient; location of bruises, scars, dressings; site of previous injection  
When you give an intramuscular injection, at what area should you insert the needle?  90\u00B0 angle  
What is the purpose of using this angle?  to be sure the bevel of the needle is completely within the muscle  
What angle is used for giving a subcutaneous injection?  45\u00B0 angle when using a 5/8-inch needle; 90\u00B0 angle when using a 1/2-inch needle  
What is the maximum amounr of medication that can be given in one intramuscular site?  3cc  
What should you do if the dose ordered is larger than the maximum amount?  divide the dose and give in two different sites  
If a medication reference book states that a medication should be given deep IM, what site(s) might you choose to inject?  dorsal gluteal, vastus lateralis  
What is the purpose of rotating subcutaneous injection sites for insulin?  to prevent over-injection in one area and to promote absorption  
Where is the preferred site for heparin injection?  abdomen  
What type of syringe and size of needle are used to administer heparin?  tuberculin syringe and 1/2-inch 23 or 25 gauge needle  
How does the angle of injection for heparin differ from the usual subcutaneous injection?  it is given at a 90\u00B0 angle  
List two sites used for intradermal injection  inner surface of the forearm; upper back  
At what angle is the needle inserted for an intradermal injection?  15\u00B0 angle  
How is the result of an intradermal injection read?  by the amount of induration around the injection site  
Explain how you would select a syringe and needle to give an injection to a child  age and body size of child; type and amount of medication to be injected; shorter needle than used for adult; may need a tuberculin syringe to measure very small amounts of medication accurately  
Which intramuscular injection site would you choose when the patient is an infant or young child?  vastus lateralis, because it is the largest muscle at that age; Invite a pediatric nurse to discuss administering injections to children  
How would you evaluate the effectiveness of heparin  PTT & mouth and vaginal bleeding, SQ bleeding, blood in urine  
How can the effectiveness of an insulm injection be evaluated?  FSBS and listen to the ot.  
How can you tell if an antibiotic injection is effective against infecting microorganisms?  Cultures- signs and symptoms or infection
