00:00	Good day and welcome to Tech Mouth Channel in this
00:02	video that we're looking at some more are nursing calculations
00:05	. Now . With this particular video , I'm interested
00:08	in looking at some video . Some calculations where we're
00:12	gonna be looking at uh where doses are prescribed either
00:16	you know , to be given three or 4 times
00:18	a day , three times a day , four times
00:20	a day . Um or every six hours or something
00:23	like this . And how we deal with those .
00:25	Okay , so where medication is prescribed over a period
00:28	of time . Okay . Um and or two of
00:32	these as we go along , I think examples of
00:33	the best way to deal with these and I'll give
00:35	you an example of where this might occur . Um
00:37	a child weighing 23 kg has prescribed dioxin uh 8,000,008
00:45	micrograms per kilograms per day . 12 Alley . Okay
00:49	. So beginning of every 12 hours , how much
00:51	should he be given or how much should be given
00:53	in a single dose . Now , the way we
00:55	deal this first is we have to work out how
00:57	much medication they have to get for the day .
01:00	Okay ? So this child weighs 23 kg . Okay
01:04	? Uh , and they're getting eight million mark programs
01:08	kilograms . So this if we multiply this a 23
01:16	we're going to get the answer of 100 and 84
01:20	. So during the day , this kid should get
01:22	100 84 micrograms of this medication , dioxin , dioxin
01:29	and whatever . Um , yeah , They're going to
01:33	get this 12 hours . So , if you get
01:34	this 12 valley , you can imagine this . There
01:37	are 24 hours in a day and Tall Valley .
01:43	That means they're going to get it twice for the
01:45	day . Okay , That makes sense . Maybe you're
01:47	giving at six o'clock in the afternoon , in the
01:49	evening and then six o'clock in the morning , but
01:52	12 hours every 12 hours is twice a day .
01:54	Hopefully you see that because 24 divided by 12 equals
01:59	two . Okay , this is really important little thing
02:02	to get . So if you're working out how much
02:04	should be given in a single dose , you should
02:06	realize in this , that the kids getting uh Two
02:09	doses all up beginning of every 12 hours . We
02:11	divide our answer here by two . Okay , so
02:15	that means the kid should get 92 micrograms Every our
02:21	dose . Okay , let's be very , very careful
02:23	with this because there's a tendency of people I've noticed
02:26	to actually divide by 12 automatically , but that's not
02:29	the case . Okay , Okay , a child weighing
02:34	18.5 kg has subscribed sodium val pride 10 mg per
02:39	kilogram per day . In three doses , how much
02:41	should be given in a single dose . So first
02:44	off , we're going to work out how much this
02:46	kid should get for the day , okay , 18.5
02:49	kg 10 mg per kilogram , you might be able
02:52	to work that out And then we're going to split
02:54	this over three doses . Okay , So the way
02:57	we do this is as follows . First , let's
02:59	let's work out their medication for the day . So
03:01	they're getting 10 mg and they're getting this every kilogram
03:05	they have , so they have 18.5 kg . So
03:08	all up this kid is getting 100 and 85 mg
03:13	of this sodium Valparaiso it , so we're splitting this
03:16	over three dosages . So to do that , we're
03:20	dividing our answer by three . Okay . Before ,
03:23	and the other question we had , we were asked
03:25	it was by the hour . This is actually already
03:27	split into the amount of dosage is getting . So
03:29	just dividing by 31 85 divided by three is 61.67
03:36	milligrams . Okay , let's have a look at another
03:41	one . A 75 kg patient is ordered medications ,
03:46	six mg per kilogram per day to be given every
03:50	four hours , what medications should they get each dose
03:54	? So first off again , work out how much
03:55	medication they're getting for the day , they're getting six
03:59	mg and they're getting this for every kilogram , there's
04:03	75 kg . So all up , they should be
04:05	getting 450 mg of said medication . Uh and this
04:11	is to be given every four hours . Now ,
04:13	this for every four hours . Uh this is not
04:16	telling us the amount of doses are getting , it's
04:17	just telling us how often they're getting it . So
04:19	the amount of doses per day is going to be
04:23	24 divided by How many four hour lots are ,
04:28	are the answer is 6 ? Okay , so 450
04:33	divided by six . This Each one of these six
04:37	doses this are person should be getting 75 mg .
04:44	Okay , lucky . Last question , a child weighing
04:48	18.5 kg is prescribed . I can't even say this
04:52	one . Every throw Meyssan 30 mg per kilograms per
04:57	day . Six early . How much should be given
04:59	in a single dose ? Okay , let's again work
05:01	out how much this kitchen be given per day .
05:03	So we go 30 mg Where times in this by
05:09	18.5 because that's how much kg they are and we
05:14	get this answer of um 555 mg array . So
05:22	this is how much this kid's getting per day ,
05:25	they're getting this much every six hours , so Every
05:29	six hours you might be able to already work this
05:31	out in your head , every six hours 24 divided
05:34	by six , means they're going to get four doses
05:37	for the day . So we're doing it over four
05:40	doses . So we divide this number by four ,
05:42	We get the answer of 138.8 mg for every dose
05:49	. Okay , how did you go with those ?
05:50	Okay . They're not too bad . It's just a
05:51	little tweak our little something which was worth knowing .
05:54	I hope you did really good with those anyway ,
05:56	I'll see you next time .
