Apatient has been ordered medication cat a dosage of 3680 mg/day. the dosage available is 425 mg each scored tablets. • how many tablets will the nurse administer per day? if the nurse is to administer 1 tablet every 2 hours and the first dose is given at 7am, when is the last dose given?

Step-by-step explanation:

The required dosage in terms of tablets is ...

  3680 mg = (3680 mg)/(425 mg/tab) = 8.66 tabs

We don't know how the tablets are "scored", but in my experience they have a groove that facilitates them being cut in half.

We expect the nurse will administer 8 1/2 tablets per day, for a dose of 3613 mg, slightly short of the ordered 3680 mg.

9 doses will be administered over 8 time intervals of 2 hours, so will take until 16 hours after 7 am. The last (1/2) dose will be at 0700 +1600 = 2300 hours, or 11 pm.

let's cover over the formula of the vertex:

y = a(x – h)^2 + k

in this formula, (h,k) are the vertex, always remember that the positive or negative value of the vertex is based on the sign it has.

for example, if the vertex is -3,-6 then both the x and y value would have the positive sign attached to it and if it were a positive x and y value, then a negative sign would be attached to it.

with that being said, for our problem the x value is a positive one so we are looking for a number with a negative sign next to it, in this case the first and second choice.

however, for the first answer choice it isn't quite part of the formula so we know that the answer choice correctly displays the x value.

to confirm, we can see if the -1 fits correctly with the second answer choice, and as mentioned above a negative number will have a positive sign attached to it. so, for our problem we can see that -1 has been changed to +1, so we can confirm that the second answer choice is correct.

hence, our final answer is y=(x - 1)^2 + 1
