THE SCREENSHOT IS NOT CLEAR,
THE QUESTION WILLBE RE-TYPED
YOU MUST UNDERSTAND HOW EACH
QUESTIONIS SOLVED, FOR THAT I
INCLUDED THE WAY OF SOLVING IT,
YOU MIGHT FIND DIFFERENT
NUMBERS IN THE EXAM. 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
1 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!
