Converting ounces to lbs?
Divide the ounces by 16 oz., then round that number to the tenth and place it in the equation and don't round again till the end

Round everything to tenth at the end of the equation on the quiz except for...?
When converting ounces to lbs, round when dividing ounces by 16oz, and then not again till end of equation. One question on quiz will state not to round at all!

Reading from right to left, each place is 10 times larger in
value. For example, 100 is 10 times larger than 10 & 1 is 10 times larger
than 0.1

The basic unit of weight in
the metric system is the gram (G or gm). The basic length is the meter (m) and
the basic volume is the liter (L or l). Metric measurements use the decimal
system as the basis for its units. The prefix of the unit identifies its
decimal location and value.

Successful Math for
Nurses
1.
I, as the nurse, am responsible for the accuracy
of medication math and administration and can not assume that the pharmacy and
physician will always be correct.
2.
Check and recheck medication orders and doses
along with labels.
3.
Label all answers with correct unit of
measurement
a.
Exp: 4mg;
4mL; 4 units; 4mcg; 4 teaspoons
these are all VERY different amounts of medication and could KILL
someone if administering the wrong dose due to label error.
4.
Think about the test question and what it is
asking. Does your answer even make sense?
a.
Capsules
will be whole number. Do not crush, do not divide
b.
Tablets
will either be whole or half number
c.
Liquid/suspension
in OZ or mL whole numbers down to tenths
d.
Syringe
whole number down to hundredths
e.
Insulin
ONLY in Units
f.
IV Drops
Whole number; Pump Whole numbers to hundredths with Peds and special
medication drips.
g.
Temperature
Do not round. Can be whole or to the tenth (98.8 F)
h.
Weight
Whole numbers in Lbs or kg with OZ. Be sure and do your conversion to and from
OZ in your equations.
5.
Do not round in the middle of an equation, only
at the end if indicated.
6.
Plug your answer into the equation to check your
answer.

Write unit instead of U
Write international unit instead of IU
Write daily, every other day instead of QD, QOD
Never trail 0 after a decimal, always put 0 before a decimal
Write morphine sulfate or magnesium sulfate instead of MS, MSO_{4}, MgSO_{4}

Write mcg or microgram when using mcg
Use half strength or bed time instead of HS
Write 3 times a week or three times weekly instead of TIW
Write SubQ, subQ, or subcutaneously instead of SC or SQ
Write Discharge instead of D/C
Write mL or milliliters instead of cc
Write left ear, right ear, or both ears instead of AS, AD, AU
