Dosage Calculations Final Exam Study
Guide
_____ capsules cannot be opened and mixed with food or fluid - ANS-sustained-release
\_____ tabs cannot be crushed - ANS-enteric-coated
\1 mL syringe calibrated in - ANS-0.01 mL increments
(0.257 to 0.26)
\3mL syringe would be calibrated to - ANS-0.1 mL increments
\accidental overdose of insulin may result in - ANS-irreversible insulin shock or death
\Advantages of IV Med Administration - ANS--Rapid onset of action
-Decreased drug loss to tissues
\Always label vials after reconstitution if they will be used again with the following..... -
ANS-*Name of medication
*Dosage strength
*Storage directions
*Date and time of reconstitution
-Initialed by the nurse
*Expiration date
*Route of administration
\amounts of 0.5 mL to 1mL calculate in tenths and measured in - ANS-1mL or 3mL syringe
\amounts of 0.5 to 1mL calculated in - ANS-tenths
\Calculate: - ANS-dosage on hand = dosage desired
amount on hand = X amount desired
\Central line - ANS--Accommodates larger concentrations and volumes of fluid
\Check every 30 min to 1 hour: - ANS--Fluid volume remaining -Infusion rate -Signs of
complications
•Phlebitis •Infiltration •Infection
\Check institutional policy regarding - ANS-correction of off-schedule IV rates and percentage of
variation allowed
-Should not exceed 25 percent
\Check the Six Rights at 3 Different Points During Med Administration: - ANS-1. Check meds
against MAR before/during administration and also check for med allergies
2. Check meds AFTER preparation
3. Check meds at the bedside: also check blood pressure and/or pulse or blood sugars if
needed BEFORE giving meds that affect the BP, pulse, or blood sugars. AND always check
allergy band.
***You will check patient name and DOB as well as check MR # on armband against MAR
before giving meds at bedside as well***
\Choice of Solvent is based on.... - ANS--the pH
-the physical properties of the product
, (medication)
\Clear to cloudy rule - ANS-draw up clear insulin (regular) first then draw up cloudy (NPH)
insulin
\Common drop factors: - ANS-10 gtt/mL - macro-drip tubing
15 gtt/mL
20 gtt/mL
60gtt/mL- pedi-drip tubing or micro-drip tubing
\continuous infusions - ANS-used when patient needs to receive continuous (around the clock)
or maintenance IV fluid therapy.
\Convert: - ANS-- all units of measurement must be in same system and all units must be in
same size
-if not, convert before proceeding
\D - ANS-Dextrose
\Disadvantages of IV Administration - ANS-Phlebitis
Air emboli
Infiltration
Sepsis
\Displacement Factor: - ANS-amount of space that is taken up by the medication in the powder
or crystal form
\Dosage Strength/Concentration: - ANS-Reconstitution does not change the amount of
medication in the vial; it changes the concentration or dilution of the drug
Displacement factor is noted by manufacturer on label
The label on the medication vial states the strength (amount) of medication in the vial. That
amount never changes. The only thing that can change is the amount of diluent (liquid) that is
added
\dosages for oral liquids: - ANS-calculated in mL
\Drop Factor: - ANS-Sometimes, a pump is not available
Some meds are given without using a pump
Gravity is used to allow medication to "drip" in
Drip rates must be calculated as gtt/min
You must know the drop factor of the tubing that is being used in order to calculate a drip rate
for a gravity infusion
This is found on the IV tubing package
Or, it will be given to you in a problem on a test
\Drops per Minute (gtt/min) - ANS-•Carry calculations to one decimal
•Round drops per minute to nearest whole number
•Can watch-count only whole drops
Calculated as= gtt/min
