1. You receive an order for Tylenol grains 15. You have available Tylenol 160 mg. in 1.6 ml. Rx? And S? Show all work

Answer 1

To solve this problem, we need to find the conversion factor that will allow us to convert the given unit (mg) to the desired unit (grains).

1 grain is equivalent to 64.799 milligrams (mg). Therefore, the conversion factor is:

1 grain / 64.799 mg

Now let's use this conversion factor to solve the problem.

Given:
Tylenol: 160 mg in 1.6 ml

To find the number of grains in 15 mg of Tylenol, we can set up a proportion:

160 mg / 1.6 ml = 15 mg / X grains

To solve for X (number of grains), we cross multiply and divide:

160 mg * X grains = 1.6 ml * 15 mg
160X = 24
X = 24 / 160
X = 0.15 grains

Therefore, the order for Tylenol in grains would be 0.15 grains. The prescription (Rx) would state "Tylenol grains 0.15" and the supply (S) would be "Tylenol 160 mg in 1.6 ml."
