Who is Charles Darwin?
Darwin is the first of the evolutionary biologists, the originator of the concept of natural selection. His principal works, The Origin of Species by Means of Natural Selection (1859) and The Descent of Man (1871) marked a new epoch.
What is Visible light wavelength?
Visible light wavelengths are between 400 and 700 nanometers.
Visible light waves are the only electromagnetic waves we can see. We see these waves as the colors of the rainbow. Each color has a different wavelength. Red has the longest wavelength and violet has the shortest wavelength. When all the waves are seen together, they make white light.
When white light shines through a prism, the...

How to calculate tablet dosages:
Posted By: Admin on May 12, 2010 in Nursing Math - Comments: 2 Comments »
How to calculate tablet dosages:
This formula is used to calculate the number of tablets to be administered when given the required dose.
| Desired Dose —————— Available Dose |
= Number of tablets to be given |
N.B. Units for desired dose and available dose must be the same.
Example 1:
A client is ordered 150mg of aspirin. 300 mg aspirin tablets are available. How many tablets would you give?
| 150 mg —————— 300 mg |
= 1/2 tablet |
Example 2:
How many tablets containing 62.5 mcg will be required to give a dose of 0.125 mg?
STEP 1 : CONVERT TO SAME UNITS
Convert 0.125 mg to mcg.
The decimal place is moved 3 places to the right.
0.125 mg = (0.125 * 1000 mcg)
= 125 mcg
STEP 2: CALCULATE
| 125 mcg —————— 62.5 mcg |
= 2 tablets |
