1. Basic Math Why is Math Important in Health Care?

2. Military Time  Based on 24 hour clock  No am or pm  Expressed in 4 digits  0000  1 st 2 numbers = hour  Last 2 numbers = minutes

4. Graphs:

5. Systems of measurement  Household  Metric

6. Household:  Used in home  Teaspoon, tablespoon, pint, quart, gallon  Pound, inch, foot, yard  Can convert to metric by simple math

7. Metric system:  Most widely used in health care  Decimal system; based on # 10  Monetary system in U.S. is based on metric

8. Metric system basic units:  Based on meter, gram & liter  Meter (m): length  Gram: (G), g, OR gm): Weight  Liter (l): liquid

9. GREEK AND LATIN PREFIXES:  Centi - 1/100  Milli - 1/1000  Kilo - x 1000

10. Metric System Uses:  Medications  Measure fluid intake  Measure urinary output  Measure newborn weight & length

11. Common equivalents:  Distance:  1 meter =  100 centimeters = 3.28 feet  2.54 cm = 1 inch

12. Weight:  1 Kilogram (kg) =  1000 gram (g)  = 2.2 pounds (lb)  500 g = 1 lb

13. Volume:  1000 milliliters (ml) = 1 liter (l)  1 ml = 1 cubic centimeter (cc)

14. Memorize these Metric & household Equivalents:  1 liter = 1 quart  30 ml = 1 ounce (2 tbsp)  15 ml = 1 tablespoon  5 ml = 1 teaspoon

15. 1 kg = 2.2 pound  1 ml = 15 drops  1 inch = 2.5 cm

16. So…. 1 mm = meter 1cm=meter 1km=meter 1ml=liter 1L=liter 1000ml=liter 2000mg=grams 1000mcg=grams

17. 250ml=L 0.5L=ml 2G=mg 500mg=G 0.0300G=mg 0.05mg=G 1mcg=mg 2kg=lbs 60mg=G

18. 0.005L=ml 200ml=L 0.0065G=G 3.5cc=L 4KG=G 1ml=L 0.05mg=G

19. Temp conversion you must remember: F to C F-32 x 5/9=C Example:98.6F 98.6-32= 66.6

20. 66.6 x 5 = 1 9 333 9 =37C

21. C to F C x 9 / 5 + 32 = F Example:37C 37 x 9 = 333 333 / 5= 66.6 66.6 + 32 = 98.6

22. Practice: 95F=C 40C=F 94F=C 38C=F 101F=C 10C=F

24. I.The Scientific Method A. An organized approach to learn how the natural world works. 1. Ask a question

25. 2. Form a hypothesis (a proposed explanation)

26. 3. Perform an experiment

27. 4. Analyze the data

28. 5. Make your conclusion

29. II. The Importance of the Scientific Method A. Continues to allow science to grow B. Is testable by anyone else, and the outcome should be the same.
