Dose is 0.5 mg x kg
Child’s weight is in pounds, so we have to convert it to
kg
1 Kg = 2.2 pounds (lb)
X kg = 42 lb
X = 42*1/2.2 = 19 kg
So the dose is 0.5 mg x 19 kg = 9.5 mg
---------------- that’s the 1st part to get into the final part
of the question which is how many ml should be
administered? In other words, to get 9.5 mg delivered,
how many mL should be given?
The key answer is how much solution, ampule, syrup ….
you have (in other words, the fixed amount of medicine
that would be supplied for you from the pharmacy)
So here we have 25 mg / mL in each ampule, and we
need to give 9.5 mg, if you arrange it in an equation, it
will be:
25 mg ---- 1 mL
9.5 mg ---- x mL (x is always the missing amount that you need to know)
X = 9.5 x 1/25 = 0.381 --> round to nearest tenth = 0.4
,Question: the healthcare provider prescribes captopril 37.5 mg
PO daily. The medication is available in 25 mg tablets. How
many tablets should the nurse administer? (Enter numeric only,
if rounding is required, round to the nearest tenth).
This should be the easiest questions and sometimes you don’t
even need to use the calculator, imagine you have a medicine
regardless of its name, and it comes in strength of 25 mg, you
need to give 37.5 mg, both are same units, so your main
concern is how to get 37.5 out of 25? just divide them! And you
will get 1.5 tablets! Easy and straight!
After you have the answer, just double check yourself, and
imagine you have the medicine next to you, and you have 1
tablet of 25 mg and half tablet of 25 mg which is 12.5mg, add
them together, 25 + 12.5 = 37.5, which what we need! So your
answer is correct!
Let’s move to the next question!

Question: The PN administers amoxicillin/clavulanate 500 mg
PO every 8 hours to a client with a staphylococcus infection. In
a 24 hour period. How many mg of amoxicillin/clavulanate
should the client receive?
(Enter the numerical value only. If rounding is required, round
to the whole number.)
If you don’t have a good pharmacology/microbiology
background, don’t freak out! Just ignore the name of
medications/bacteria. 99% they have nothing to do in
calculation questions!
Just understand the question and you will have the answer by
your self!
You are talking a medicine with a strength of 500 mg every 8
hours, how many mg you will take in 24 hours?
So in other word, how many 8 hours are there in 24 hours? 3!
500 mg x 3 = 1500 mg!
Easy!
