Solutions To Dosages

Clinical

Dosages

Study Guides

Some people are not so happy about this class because it involves numbers and stuff and a lot of people do not like numbers.

And just remember when you're taking those clinical dosage tests, you have FOUR tries. How fun- you get to work yourself into a  nervous frenzy four times (then you fail). Just kidding, I don't actually know anyone who didn't make it at least on time #4. 

Nothing can make me lose sleep like a dosages test and my hands sweat just thinking about it. Once my friend James said as a joke, "Math test today!" (he's a riot). Instant tachycardia and diaphoresis. Then five minutes later, my teacher said FOR REAL , "It's time for the math test." I had to be defibrillated. How did I miss that it was dosage test day?

So in case you just failed test #3 or just want some extra practice for Dosages and Solutions, here are some resources:

Mr. S's Rounding Rules:

That sounds like a kids' show or something

(These are, like, official and stuff)

Zero Rules for Decimals

1.    All numbers less than 1 must have a zero placed before the decimal point.

a.    Example:  .5 should be written 0.5

b.    Example:  .032 should be written 0.032

2.    Leave no trailing zeros after the decimal point.

a.    Example:  3.0 should be written 3

b.    Example:  5.380 should be written 5.38

c.    Example:  6.2003700 should be written 6.20037

Decimal Rounding-Off Rule

1.     Determine to which place value to the right of the decimal point you are rounding off the number.  Look at the digit following that place value.

a.    If that digit is 5 or larger, then drop that digit and add 1 to the previous digit.

                                          i.    Example: 5.26 rounded to the tenths place = 5.3

b.    If that digit is 4 or less, then drop that digit.

                                          i.    Example: 5.234 rounded to the hundredths place = 5.23

2.    Weights and Temperatures should be rounded to tenths.

Syringe Selection

1.    Dosages more than 1 mL in volume should be calculated and rounded off to the tenths place and then administered in a 3-mL syringe.

2.    Dosages less than 0.5 mL in volume should be calculated and rounded off to the hundredths place and then administered in a 1-mL syringe.

3.    Dosages more than 0.5 mL and less than 1 mL in volume can be calculated and administered in either a 1-mL syringe (round calculation to hundredths) or a 3-mL syringe (round calculation to tenths).

IV Rounding

1.  IV rates calculated in drops per minute (gtt/min) should be rounded to the appropriate whole number.

            a. A calculated rate of 12.6 gtt/min is rounded to 13 gtt/min.

            b. A calculated rate of 14.2 gtt/min is rounded to 14 gtt/min.

2.  IV rates calculated in milliliters per hour (mL/hr) should be rounded to the appropriate whole number.

            a. A calculated rate of 84.5 mL/hr is rounded to 85 mL/hr.

            b. A calculated rate of 23.3 is rounded to 23 mL/hr.
