2 IV Medication b Flashcards
CONCENTRATIONS
Some medications are provided as a “neat” solution (so it is given
without dilution)
Others need to be diluted as they are either too potent or unstable in
plastic (therefore are provided in a glass ampoule and then added
later)
Isotonic crystalloids have a tonicity equal
Isotonic crystalloids have a tonicity equal
When a crystalloid contains fewer electrolytes than the plasma, it is
less concentrated and referred to as
hypotonic
When a crystalloid contains more electrolytes than plasma, it is
referred to as
hypertonic.
CONCENTRATION OF SOLUTIONS
mass of the solute divided by the volume of the solute
RECONSTITUTING MEDICATION
DISPLACEMENT
Some IV medications are provided as powder in a glass
vial that needs to be made up to a form that can be
administered parentally.
Depending on the volume of powder, there will be a
displacement value so adding water to a volume of
powder means you get more volume at the end.
GENERAL RULES

MORE CONSIDERATIONS OF SAFETY
Be diligent and follow all policies related to medication calculations,
preparation, and thorough assessment of patient status before and after an
injection. Medication errors are the most common preventable errors in health
care.
Use a blunt filter needle or blunt needle when preparing injections. Never use a
needle when injecting IV medication. Always use a needleless system.
After preparing the medication, always label the medication syringe with the
patient name, date, time, medication, and dose. Never leave the syringe
unattended.
Administer the post medication saline flush at the SAME RATE as the IV

Assess the patient’s symptoms and need for IV medication prior to
administration.
Assess the patient’s understanding of the medication.
Know the consequences of the medication
