4. Now, what can
you say about
the pictures?

5. How about these
pictures?

6. Did you hear this saying
before? What can you
say about this?

7. 1. How many ml of a medicine are in
three bottles if one bottle has 60 mL?
2. How many mg of a drug are in 8
capsules if 6 capsules contain 3000
mg?
3. How many mg of a medicine are in 3
tablets if 2 contain 10 mg?

8. Oral drugs are administered orally can be in the
form of tablet, capsule or liquid. Oral drugs are
mostly available in a limited number of strengths
or concentrations. It is, therefore, very important
that you have the skill to calculate prescribed
dosages for different drug forms.

9. For you to administer an oral drug
safely, you must make sure that it is
the correct drug with the right
dosage. Therefore, it is very vital that
you would be able to read and
interpret oral drug labels.
1. Identify the drug name.
Pay attention to the active, or generic
name, since too much of an active ingredient can be harmful
if you take more than one product with the same active
ingredient without knowing it.

10. 2. See the dosage strength.
Pay close attention to the labels of two same drugs which may look
exactly aside from that of the dose strength.
Can you
differentiate
the two?

11. For the best shelf life, store all
medications in a cool, dry place.
3. Check the Expiration Date.

12. 1. Use the correct units of measure to
avoid errors in calculating doses.
2. Be careful in placing decimal and zero.
3. Double-check answers.
Remember the rules to
accurately calculate drug
dosages and eliminate errors
as well.

13. 1. Prepare the equation by using ratios in
proportion.
2. Start with the solution by considering that the
product of the means is equivalent to the
product of the extremes. Means being the
middle items and extremes being the external
item.
3. Solve for the value of X.
4. Double check your work by completing the
equation using ratios in proportion.
Now these are the steps in
calculating drug dosages
using ratios and Proportions

14. How many mL of a medicine are in two bottles if one bottle has 60 mL?
1 bottle : 60 mL :: 2 bottles : X
Prepare the equation by using
ratios in proportion.

15. Start with the solution by considering that the product
of the means is equivalent to the product of the
extremes. Means being the middle items and extremes
being the external item.
1 bottle : 60 mL :: 2 bottles : X
Means
Extremes

16. Solve for the value of X.
1 bottle : 60 mL = 2 bottles : X
1 bottle x X = 60 mL x 2
bottles
1 bottle X = 120 mL bottles
bottle bottle
X = 120 mL

17. Double check your work by completing the
equation using ratios in proportion.
1 bottle : 60 mL :: 2 bottles : 120 mL.
Multiply the means
60 x 2 = 120
Multiply the extremes
1 x 120 mL. = 120 mL
If the product of the means is equal to the product of the
extremes, then the answer is correct.

18. How many mg of a drug are in 4 capsules if 3 capsules contain 1500 mg.?
Prepare the equation by using ratios
in proportion.
3 capsules: 1500 mg :: 4 capsules : X

19. Start with the solution by considering that the product
of the means is equivalent to the product of the
extremes. Means being the middle items and extremes
being the external item.
3 capsules: 1500 mg :: 4 capsules: X
Means
Extremes

20. Solve for the value of X.
3 capsules: 1500 mg. = 4 capsules: X
3 capsules x X = 1500 mg x 4 capsules
3 capsules X = 6000 mg capsules
3 capsules 3 capsules
X = 2000 mg
Therefore, the 4 capsules contain 2000 mg .

21. Double check your work by completing the
equation using ratios in proportion.
3 capsules: 1500 mg. :: 4 capsules : 2000 mg.
Multiply the means
1500 x 4 = 6000
Multiply the extremes
3 x 2000 = 6000
If the product of the means is equal to the product of the
extremes, then the answer is correct.

22. If 3 tablets contain 2400 mg, how many mg are there in 2 tablets?
Prepare the equation by using
ratios in proportion.
3 tablets : 2400 mg :: 2 tablets : X

23. Start with the solution by considering that the product
of the means is equivalent to the product of the
extremes. Means being the middle items and extremes
being the external item.
Means
Extremes
3 tablets : 2400 mg :: 2 tablets : X

24. Solve for the value of X.
Therefore, the 2 tablets contain 1600 mg .
3 tablets : 2400 mg = 2 tablets : X
3 tablets x X = 2400 mg x 2 tablets
3 tablets X = 4800 mg tablets
3 tablets 3 tablets
X = 1600

25. Double check your work by completing the
equation using ratios in proportion.
3 tablets: 2500 mg. :: 2 tablets: 1600 mg.
Multiply the means
2400 x 2 = 4800
Multiply the extremes
3 x 1600 = 4800
If the product of the means is equal to the product of
the extremes, then the answer is correct.
