need help with med math ati

If someone can send me a link to practice questions for those that would help a lot tooo!

I don't know what ATI is, but you are so close to passing, and you can do it. Try to slow down and take some deep breaths, now and when you are taking the test. I failed one of my math tests in nursing school too, and had to re-take, and that was the last chance, so I can relate. Good luck, you're going to pass next time!

ATI is this one lame program that we get at our nursing school. I hope so too but I just wanna know what I did wrong so I could correct my mistakes.

Here, let's try one:

The dosage for drug x is 5-20 mg per kg per day.

The drug should be given every 6 hours. What is the MAXIMUM dosage of drug x that should be given per dose to a 10 kg pt?

20mg x 10kg = 200 x 4 (because 24hr/6hrs = 4hrs) = 800mg maximum per day?

Ok, first....stop and look at what the question is really asking you. It's asking ultimately asking what is the maximum PER DOSE, but first you need to know first what the maximum amount is per day.

The dosage for drug x is 5-20 mg per kg per day. ok so 20 x 10 = 200mg

200mg is your max PER DAY.

Now, you need to give it Q 6hours (4 x per day)

200/4 = 50, so 50mg is the max dose you would give at any one shot when giving in 4 divided doses.

Ohhh i did the opposite.

On my med math question for this term its all about converting g to mg

and the divided into doses question which i need help on

The max daily dose for tylenol is 4grams per day.

If giving four times per day, how many mg per dose?

If giving 6 times per day, how many mg per dose?

ATI is not 'lame'. It prepares you VERY well for NCLEX . If you pass ATI in school , you will pass NCLEX on first try ---99% guaranteed.

All of the class in my cohort did.

20mg x 10kg = 200 x 4 (because 24hr/6hrs = 4hrs) = 800mg maximum per day?

Be mindful of your units. When you divide 24 hours by 6 hours, what you're trying to figure out is how many 6-hour time blocks "will fit into" 24 hours, right? The answer will be that six hours fit into 24 hours a certain number of times. The answer will never be "hours". It will simply be a number (of times). In this specific case, the answer is 4.

Anytime you divide a unit with the same unit they will cancel out.

On my med math question for this term its all about converting g to mg

and the divided into doses question which i need help on

a) Convert 250 mg to g 250 / 1000 = 0.25 Answer: 250 mg equals 0.25 g

b) Convert 80 mg to g

c) Convert 136 mg to g

d) Convert 0.2 mg to g

e) Convert 322 mg to g

f) Convert 2000 mg to g

g) Convert 0.5 g to mg 0.5 * 1000 = 500 Answer: 0.5 g equals 500 mg

h) Convert 0.002 g to mg

i) Convert 3.2 g to mg

j) Convert 0.014 g to mg

k) Convert 500 µg to mg 500 / 1000 = 0.5 Answer: 500 µg equals 0.5 mg

l) Convert 1000 µg to mg

m) Convert 3250 µg to mg

n) Convert 0.51 mg to µg 0.51 * 1000 = 510 Answer: 0.51 mg equals 510 µg

o) Convert 0.09 mg to µg

p) Convert 6.3 mg to µg

(I'm not sure if micrograms (µg) are included in your test, but I added them because many medications come in that strength).

q) 4 tablets each contain 250 mg. What is the total dose in milligrams? In grams?

r) 500 mg is the prescribed dose. Tablets are 250 mg each. How many tablets will you give?

s) 625 mg is the prescribed dose. Tablets are 1.25 g each. How many tablets will you give?

t) 1 mg is the prescribed dose. Tablets are 500 micrograms each. How many tablets will you give?

u) 1.5 g is the prescribed dose. Tablets are 750 mg each. How many tablets will you give?

v) 2.25 g is the prescribed daily dose. If given 3 times per day, hos many mg per dose will you give?

w) 1.2 g is the prescribed daily dose. Tablets are 150 mg each. If given 4 times per day, how many tablets per dose will you give?

OP, if you try figuring out and posting the answers to these (or some of them) I'll try to get back to you as soon as I can. My work schedule is pretty hectic right now so it might not be instantaneous though :) I'm not sure if the level of the questions I wrote are appropriate, but I hope they can be of some help.
