Having the same osmotic pressure as another solution Isotonic
1/2 NS = 0.45% Sodium Chloride
Sodium Chloride/NS is isotonic with _____. blood
Used for reconstitution Sodium Chloride, Sterile Water
Hypotonic solutions have a ______ osmotic pressure than red blood cells. lower
Used for patient fluid replenishment. Ringer's Solution
Drug is injected in the loose tissue beneath the skin: Subcutaneous (SC or SQ)
Drug is injected into muscle mass: Intramuscular
Drug is administered into the veins: Intravenous (IV)
With the exception of lipids, IV injections of solutions that are "_____________" should not be administered. cloudy in appearance
When should you disinfect the hood? At the beginning and end of work shift, hourly during operation, and after spills or known contaminaiton
The Laminar Air Flow Hood should be running for at least _____ minutes before using. 30
You must work at least _____ inches within the hood. six
Avoid working over _________ to prevent contamination fall into preparation area. open containers
Blocking areas of preparation that must remain sterile from the air flow, thus allowing for contamination is called: Shadowing
Areas behind objects in the airflow. Dead spaces
Sterile product preparation room should be free of ______, especially _____ as a source of particles. dust, cardboard
Sterile room should be kept away from ___________. common routes of personnel traffic
While laminar air flow hoods prevent airborne contamination, they do not __________. guarantee a sterile products
Prior to compounding, remove rings, watches, and bracelets which are ideal for _______ to hide. bacteria
While working in the hood, do not introduce items that are not _________ for the preparation (ex. papers, pencils). essential
For drugs in a vial in powder form. it is necessary to reconstitute with a suitable ______. diluent
Prior to compounding, wash hands and forearms to the elbows with the appropriate ________ agent. This should be done for at least ______. germicidal, 30 seconds
When introducing liquid into a plastic IV bag, the needle must be at least _____ inches to penetrate the diaphragm. 1/2
Containers made entirely of glass. Ampule
When withdrawing liquid from a vial, remove the cover of the vial and wipe rubber surface with an ______________. alcohol swab
Before withdrawing necessary amount of liquid from a vial, you should withdraw the same volume of __________ into the syringe, air
What should you do when there are air bubbles in the syringe? Tap the syringe to make all of the bubbles go to the top, then pull down and back up to remove it
Do not _____ needles. clip, bend, or recap
How should you open an ampule? Hold the ampule neck with a gauze and snap it open quickly.
A _______ should always be used when withdrawing from an ampule to prevent glass particles from getting into the liquid. filter straw/needle
In preparation of parental products, do not ______, thoroughly _____ instead. shake, rotate (or tilt or roll)
Why is isotonicity important? Because the injectable solution needs to be isotonic with the blood.
Important characteristics of parenteral products are: acid content of the pH of the solution, and color and clarity of an IV
What should you do to detect particles in an IV bag? Hold the product in the light or a dark background
What is Total Parenteral Nutrition (TPN)? An IV nutritional solution
TPNs that contain lipid emulsions are not clear, therefore: precipitation cannot be seen
_____ is a protein source. Amino Acid
IVPB is the administration: of a second solution into an already established primary line
High concentrations of _______ is a carbohydrate source. dextrose
An IVPB must be hung ______ than the primary solution. higher
______ emulsions are a fat source. Lipid
Used to bathe or flush open wounds or body cavities. Irrigation

If a vial is _________ with air, a spray or spill may occur when removing the needle. over pressurized
Hazardous waste container should be: removed from the work area and destroyed.
Why are antineoplastic agents a special concern? Because of their mutagenic and carcinogenic effects
