CPSS Exam 1
Small bottle that contains the drug - Answer-Ampule
Diameter of the needle - Answer-Gauge
Enlarged base by which a hollow needle may be attached to a device (as a syringe) - Answer-Hub
Cylindrical container that holds liquids - Answer-Barrel
A small container, usually with a closure, used especially for liquids - Answer-Vial
What are the reasons to give an injection? - Answer-- if drug is poorly absorbed or degraded by GI
system
- if pt is uncooperative, unconscious, unable to take PO
- used when localized therapy is desired
- preferred when rapid & predictable drug response is desired in ER situations
What is the needle size used for blood withdrawal? - Answer-18 g
,What is the needle size used for IM injections? - Answer-22g
What is the needle size used for SubQ injections? - Answer-25-27g
What needle size is used for ID injections? - Answer-26-27g
What type of injection has the fastest rate of absorption? - Answer-IV > IM > SQ
When are IM injections indicated? - Answer-- drugs are not easily absorbed PO
- when you want an intermediate rate of onset & duration of action
- when parenteral delivery is necessary
What are the 3 main sites of IM injections? - Answer-- gluteal (upper outter quadrant)
- deltoid (lateral & 3-4cm below the acromion)
- vastus lateralis (antero-lateral, upper thigh)
Which IM site is preferred in infants & kids under 3? - Answer-Vastus lateralis
*painful due to fascia lata
*lack of nerves and vessels
Which IM site is preferred in kids over 2? - Answer-Gluteus maximus
*higher risk of hitting siatic nerve in kids under 2
Which IM site is preferred in adults? - Answer-Deltoid
*watch for radial nerve in kids
, What is an important technique to use when giving an IM injection? - Answer-Draw about 0.2ccs of air
into syringe (air lock)
Hold syringe like a dart at 90 degree angle
Max amount injected is 3ccs
*DO NOT MASSAGE- will break seal*
What are the complications associated with IM injections? - Answer-- inject into vessel
- inject into nerve
- needle breaks off
- sterile/septic abscess
Which type of injection is used for drugs requiring slower absorption and longer duration of action? -
Answer-SubQ
*drugs must be soluble and potent in small concentrations
What are the 3 common sites used for SC injections? - Answer-- upper outer arm
- anterior thigh
- lower abdomen
What are the MC SC injections given? - Answer-Heparin & Insulin
*refrigerate insulin
*Do NOT aspirate or massage heparin injections
How is insulin mixed? - Answer-Rolled between palms of hands - gently!
