LEQs
Why is knowledge of mathematics essential for the health care worker?
What is Military Time and why do we use it in health care?
What mathematical skills are used most frequently in health care?
What is the relationship between Celsius and Fahrenheit?Slide3
Reading a 24-hour clock
Example
- what is 17.42 in the 12 hour clock?
Start
by taking 12 from the hours
: 17 - 12 = 5.
So
17.42
is the same as
5.42 pm
, which is 42 minutes past 5 in the evening.Slide4
It’s useful to know this time as ‘so many minutes’ to 6 as well, so how do we work out the minutes before 6?
Take the minutes
away from
60, as there are
60 minutes
in 1 hour:
60 - 42 = 18
So it’s 18 minutes to 6 in the evening. Slide5
Look at the opening hours for this shop.
What
time does it close during the week? What about Saturday and Sunday?
Monday to Friday it closes at 18.00 which is 6.00 pm.
On Saturday it’s 17.30 which is 5.30 pm.
On Sunday it closes at 16.30 which is 4.30 pm.Slide6
What about converting a time into the 24 hour system?
For
example what is
3.36 pm
in the 24 hour clock?
If the time
is pm
, add 12 onto the hours (the number in front of the point): 3 + 12 = 15So 3.36 pm will be 15.36 in the 24 hour clock.Slide7

Medical Math Conversion Chart
Punch holes and put it in your notebookSlide22
Medical math
Copy these notesSlide23
Apothecary system – based on 12-ounce pound
Officially replaced by metric system
Standard unit of measure for weight (solid substances) is the grain (gr)
Liquid volumes (fluids) are measured by minim
Rarely used todaySlide24
Common household system
Less accurate
Primarily used by patients who take medication at home
Practitioner’s responsibility to assure consumer is taking correct dose
Necessary for practitioner to know equivalents from “pharmacy language” to every day common household termsSlide25
Conversions
Standard teaspoon established to contain approx. 5 ml
60
gtt
(
gtt
= drops) = 1 teaspoonful
3 teaspoonsful = 1 tablespoon1 teaspoonful = approx. 5 Gm or g (gram)1 teaspoonful = approx. 60 gr (gr = grain; not to be confused w/ g = gram)Slide26
Metric System
Most commonly used system of measurement (globally)
Easy to use since based on parts & multiples of 10
Official system of measure for pharmacy practice
Advantages: simple, brief, adaptable, universalSlide27
Metric Measures
Length = meter (m)
Volume = liter (L)
Mass / weight = gram (g)Slide28
Metric cont
Pharmacies are mainly concerned w/ weights and volumes of drugs
May encounter physician’s orders or prescription requiring conversion
Within the same system
From one system to another
Some physicians may not be aware of various existing system and may write orders that appear to jumble quantitiesSlide29
Liquid drug preparations
Creams & ointments are expressed as percentage concentrations
A certain quantity of the drug is contained in the final quantity of the product
1% hydrocortisone cream contains 1 g of hydrocortisone in 100 g of final product (actual drug plus cream)
5 % sodium chloride solution contains 5 g sodium chloride in 100 ml final product (
NaCl
and distilled water)
1 gram in 100 grams or 1/100 = 0.01 or 1%5 grams in 100 milliliters equal to 5/100 or 0.05 or 5%Slide30Slide31Slide32Slide33Slide34
