Calculations and formulas for daily practice

[alex_hamilton18]

Hi All,

Aside from medication dosage calculations.. what are the most useful formulas/calculations used by nurses on a routine/not so routine basis?

I want to brush up on my nursing math (because you can't always count on that monitor) before I start consolidation this year.

Thanks!

if i were you, i'll try learning dimensional analysis, i.e. if you haven't done so, because studies have shown that this process increases the accuracy of any calculations particulary dosage calc. i get irk a lot when nursing students use the many step process when doing their dosage calculations. for me, this is prone to many errors. that's the reason i prefer one huge equation which ties all the pertinent information given to solve a particular problem. by doing so also helps in critical thinking and logic.

MAP=sbp+2 (DBP)/3

converting Celsius to Farenheit or vice versa

A lot of conversion tables are on facility computers for handy access

There are several great books like "Math for Nurses" or "Doseage Calculations". Nursing math is not as hard as it seems. There are only a few formulas and once u got -'em-that's it. These two books go over all the different formulas u need. College algebra was more complicated than nursing math.

n/h *ml

[sleepyRN2]

MAP=sbp+2 (DBP)/3

be very careful, i don't mean to nitpick but writing the mathematical equation for mean arterial pressure (MAP) above

as MAP = sbp (systolic blood pressure) + 2 dbp (diastolic blood pressure)/3 is mathematically wrong.

it ought to be MAP = (SBP + 2 DBP)/3, which denotes that SBP is also divided by three and not just twice DBP.

and pls define all parameters so as not to be confusing.
