Question

The nurse receives an order for Medication F 5 mg intramuscularly, every 4hours as needed. The medication label states Medication F 10 mg/mL. Howmany mL total should be administered in 24 hours?

Answer 1

At first, we have to find how many mg needed for 24 hours

Since she needs 5 mg every 4 hours, then

Let us find how many 4 hours in 24 hours?

Divide 24 by 4 to find that

`(24)/(4)=6`

That means we need 5 mg for 6 groups of 4 hours

The total of mg for 24 hours = 5 x 6 = 30 mg

Now, the medication F is 10 mg/ml

That means 10 mg given with 1 ml

We need to find how many ml for 30 mg, we will use the equal ratios

`(10)/(1)=(30)/(x)`

By using cross multiplication

`\begin{gathered} 10* x=30*1 \\ 10x=30 \end{gathered}`

Divide both sides by 10

`\begin{gathered} (10x)/(10)=(30)/(10) \\ x=3 \end{gathered}`

The total for the 24 hours should be 3 ml
