Correct Answers
3 mL syringe is calibrated in 0.1 mL increments - ANSWERSround to nearest tenth
*If math calculation does not work out evenly to the tenths place, then carry division to
the hundredths place (two decimal places) and round to the nearest tenth.
1 mL tuberculin syringe is calibrated in 0.01 mL increments - ANSWERSround to
nearest 100th
*If the math calculation does not work out evenly to the hundredths place, then the
division is carried to the thousandths place and rounded to the hundredths place.
Large syringes (5-, 6-, 10-, and 12-mL) are calibrated in 0.2-mL increments -
ANSWERSDosages are expressed to the nearest tenth
maximum volume to administer by IM injection - ANSWERS*Average adult = 3 mL (for
deltoid muscle, 1 mL) *Children ages 6 to 12 years = 2 mL
*Children 0 to 5 years = 1 mL
maximum volume for subcutaneous injection - ANSWERSadult: 1mL
maximum volume for IV - ANSWERSInjectable solutions that are added to an IV
solution may have a volume greater than 5 mL
It is critical to choose the correct size of syringe to ensure accurate measurement -
ANSWERSConsider the type of syringe being used.
*The cardinal rule should always be that any dosage given must be able to be
measured accurately in the syringe you are using.
DO NOT ROUND - ANSWERSHEPARIN
if the dosage is more than the available strength - ANSWERSan amount greater than
the available quantity is going to be administered
when mixing compatible medications - ANSWERSround to the nearest 10th for each of
the meds ordered and then add the results to find the total volume to be administered
there is no conversion for - ANSWERSunits and milliequivalents
