Q:
# Cephalexin has been ordered for an adult patient; 3 grams are to be given the next 24 hours, divided into 6 equally spaced doses. How many milligrams should be in each dose

Accepted Solution

A:

Answer:I assume you mean 0.5g. This decimal is very important so make sure you are accurate in providing decimals. Ok so here goes the problem.
The order reads:give 0.5g you place this in the problem first:
0.5g | | | | capsule
-------------------------------------------------------
| | | |
then you add how it is supplied:
0.5g | 1 capsule | | | capsule
-------------------------------------------------------
| 250mg | | |
Now you need to convert g to mg:
0.5g | 1 capsule | 1000mg | | capsule
-------------------------------------------------------
| 250mg | 1g | |
cross off and eliminate which leaves you with:
0.5g | 1 capsule | 1000mg | 500 | 2 capsule
-------------------------------------------------------
| 250mg | 1g | 250 |
This eliminates grams, and milligrams and results in capsules. So multiply across and divide. 500 divided by 250 = 2 so 2 capsules (Sorry I couldn't do overstrikes but I hope you can visualize the crossing off.)Step-by-step explanation:
