Okay, this question here says, for each of the following doctor's orders, calculate the individual dose of medication.
00:07
It says, dr.
00:08
Jones prescribed plendil, this is question one, plendil 7 .5 milligrams, the drug labelgrids, plendil 2 .5 milligrams per tab.
00:26
So in order to solve these questions, you have to apply just goulos -3s, okay? so you have that in one tab, you have 2 .5 milligrams.
00:36
So if you want 7 .5 milligrams, how many tablets are you going to need? so you apply your goulos -3 here, you have 7 .5 multiplied by one, and divided by 2 .5, and this is equal to 2x, okay? so you have to divide 7 .5 by 2 .5, and this is going to be equal to three.
00:57
So x is equal to three.
00:59
So you have to give three tablets, okay? now let's go for question two.
01:04
It says, the doctor ordered a medication of a diluted 1 .5 milligrams intramuscular from a vial that is labeled 0 .6 milligrams per ml.
01:26
So again, goulos -3, you have that in one ml of solution, you have 0 .6 milligrams, but you want to give 1 .5 milligrams, so how many milliliters of solution are you going to need? you have 1 .5 multiplied by one, divided by 0 .6, and this is going to be equal to x.
01:45
So let me solve this, 1 .5 divided by 0 .6, and this is going to be equal to 2 .5, 2 .5 ml, okay? this is the answer for question two.
01:57
Now let's go for question three.
01:59
It says, a doctor's hand prescribed 20 milligrams of a medication, this is the order, and that you have 10 milligrams in five ml.
02:11
So again, goulos -3, you have that in five ml, you have 10 milligrams.
02:16
So if you want 20 milligrams, how many ml are you going to require? you have 20 multiplied by five, divided by 10, this is going to be equal to 10 ml.
02:30
This is the answer for this question here.
02:34
Now let's go for question four.
02:37
It says, the physician ordered procardia xl, 60 milligrams, this is the order, and the drug on hand is procardia xl, 30 milligrams per tablet.
02:50
So practically one tablet here has, contains 30 milligrams.
02:55
So if you want 60 milligrams, because this is the order, how many tablets are you going to require? you have 60 multiplied by one, divided by 30, this is equal to two.
03:05
So you have two tablets.
03:07
This is the answer, okay? question five says, dr.
03:12
Garza prescribed 30 milligrams of phenobarbital.
03:17
The pharmacy has 15 milligrams capsules available per capsule.
03:24
So practically one capsule contains 15 milligrams.
03:28
If you want 30 milligrams, then how many capsules are going to require? you have 30 multiplied by one, and divided by 15, this is going to be equal to two capsules.
03:40
Okay, so this is the answer for five.
03:41
Now let's move for question six.
03:43
It says, for each of the following prescriptions, calculate the individual dose, the daily dose, and the total amount needed to fill the complete prescription.
03:53
So in this case, you have, for question six, it says, amoxicillin, 500 milligrams, capsules, okay? p -o -t -i -d, it means three times a day, okay? in 14 days.
04:14
On hand, you have 500 milligrams per capsule.
04:20
So the single dose is going to be equal to, i'm going to write that here, single dose is going to be one capsule, because the order is 500 milligrams, capsules, okay? and you have 500 milligrams per capsule.
04:42
So you have one capsule.
04:43
This is a single dose...
