IPP help! 14.An order calls for 0.005% w/v isoproterenol hydrochloride IV injection in 50 mL normal saline.?
The pharmacist has on hand a 1:800 w/v isoproterenol hydrochloride aqueous solution. How many mL of normal saline should be added to the available solution to prepare the prescribed injection?
Asked by Stephine Hoffmeister 2 years ago.
First step: figure out how many g of isoproterenol are needed 0.005% w/v = 0.005 g / 100 mL = X g / 50 mL X = 0.0025 g Next we need to figure out how many mL of our 1:800 w/v isoproterenol HCl will contain the necessary 0.0025 g. To do that, we can convert 1:800 w/v to % w/v: 1 / 800 = X / 100 X = 0.125 g in every 100 mL (0.125% w/v) Once we know the %w/v, we figure out how many mL will contain the necessary 0.0025 g. 0.125 g / 100 mL = 0.0025 g / X mL X = 2 mL (The middle step could alternatively be combined with the third to solve more quickly as 1 / 800 = 0.0025 g / X mL, and we still get X = 2 mL. Including the second step just allows us to reinforce the conversion of ratio strength to % w/v.) While you state that the question asks how many mL of NS to add to the available solution, I'm assuming you meant it the other way around. You could get picky and say that adding this 2 mL to the 50 mL or NS will actually produce a more dilute prep than we want, and you'd technically be correct (0.0025 g / 52 mL = 0.0048% w/v), though this value falls within the acceptable 5% margin commonly used in compounding. In practice, the 50 mL premixes contain overfill anyway, so most preps are slightly less concentrated anyway. For most medications this is without consequence. In those that matter, we precisely measure both components and add to a separate empty IV bag. Answered by Bailey Reasinger 2 years ago.
How many chiral carbon atoms does molecule Isoproterenol have?
Isoproterenol hydrochloride is 3,4-Dihydroxy-a-[(isopropylamino) methyl] benzyl alcohol hydrochloride, a synthetic sympathomimetic amine that is structurally related to epinephrine but acts almost exclusively on beta receptors. The molecular formula is C11H17NO3 · HCl. It has a molecular weight of 247.72 and the...

The molecular formula is C11H17NO3 · HCl. It has a molecular weight of 247.72 and the following structural formula: Answered by Jacquelyne Phillippe 2 years ago.
ONE. If you look at the picture of the molecule, you'll see the one and only chiral carbon is the center carbon with the OH group, (in between the amine and the benzene ring).. Answered by Elizebeth Baites 2 years ago.
Can concerta be mistaken for cocaine in a blood test?
My son was stopped for a traffic violation and could not pass the physicaltest. A blood test was positive for .008 cocaine. He is ADHD and takes concerta daily and has for a long time. I know for a fact that he doesn't do cocaine for several reasons.
Asked by Corine Maffey 2 years ago.
Yes. While I do not know what cocaine measures vs the mg of concerta in the blood, this is definitely possible. For example, some aerosol sprays for sinus issues can lead to a positive amphetamine test. Methylphenidate (component which makes up concerta) is the closest pharmaceutical equivalent to cocaine. Through research, studies have shown that cocaine addicts cannot distinguish between the two drugs when administered intravenously Edit: Kassie: (first, I stand by my answer). I did not say meth, please re-read my answer. Depending on the test administered, false tests can occur. Please reference the following as in indicator of the possible similarties which exists with MANY drugs.

First, "those drugs would never show up on a drug test". I think you may be a little un-aware of how the procedure works. ALL synthesized products will show in a urine drug test; however, it is only those that are tested for that are indicated. Second. "it is the drugs that are in it that cause the meth to come up positive" Im a little unsure (due to wording) what you mean here. When you say it is the drugs that are in it, are you talking about meth (since that is what you thought i said)? If that is the case, EVERYTHING in meth is a what causes a positive test, meaning, meth is the product which is compromised of ingredients, specifically, C10H15N.

No this is not possible. I am a drug and alcohol counselor and drug test people every day, and there are alot of myths that people can test positive for heroine if they eat poppy seeds, or like the person who answered before me some sinus medications will make you test positive for meth. If that were possible alot of people on probation would be going to jail everyday. I give my patiensts in the rehab I work in sinus medication anytime they get sick, and they are drug tested daily and not one has ever failed for meth because of that. So all these rumors are false, there are over the counter cold medications in methamphetamine, and those would never show up on a drug test it is the drugs that are in it that cause the meth to come up positive. So maybe your son is not using cocaine, but you should just be careful and watch out for the signs. Answered by Danna Crummey 2 years ago.
the eximation of blood for cocaine is done by GC its not too hard to test for but it is most unlikely that they would test for this without first saying so. Its only a madical all they are trying to find out is if you are healthy enough to work and not die in their country leasving them with medical costs. Where do you have to have std check to go. I think that may be incorrect Answered by Maryalice Bennard 2 years ago.
no -you are in denial. get some counseling. Answered by Maurine Laclaire 2 years ago.
