The doctor writes a prescription for an insufflation for 500 mg of Amoxicillin for an adult. The active ingredient Amoxicillin is combined with a medium of Calcium Carbonate. There is a 1:3 ratio of Amoxicillin to Calcium Carbonate. The same insufflation needs to be created for an infant; the total weight of the new insuffulation is 300 mg. What is weight of Calcium Carbonate for the new insuffulation and what is the weight of Amoxicillin for the new insuffulation?

What is the simple wayto convert 222mcg into ml???

One way is , Let the aamount of amoxicillin be x, then Calcium carbonate is 3x

therefore x + 3x = 300 mg

4x = 300 mg
x = 75 mg Amoxicillin
3x= 225 mg Calcium carbonate.

Let me know if this answer is correct. If not i will try with another method.

Snce KCL is administered 80 ml in 1 hr

hence for 1 l i.e 1000 ml will be given every 12.5 hrs

40 mEq = 12.5 hrs
hence in 1 hr
40 /12.5 = 3.2 mEq /hr
3.2 mEq/ hr is the answer.

This is a dilution problem, (Q1*C1 = Qf*Cf). Let's convert the measurements to friendly appearances: 0.5 L = 500 mL, 1:5000 = 0.02%, 1:1000 = 0.10%; Q1*(0.10%) = (500 mL)*(0.02%), Q1 = 100 mL; Qf = Qh2o + Q1, (500 mL) = Qh2o + (100 mL), Qh2o = 400 mL. You need 100 milliliters of the stock solution with 400 milliliters of sterile water to make half a liter of 0.02% epinephrine solution.

Jayb1 in Merced, California said: How many grams of 1 hydrocortisone cream should be mixed with 30g of 2.5% hydrocortisone cream to make 2% hydrocortisone cream

This is a mixture problem which can also be solved using alligation. Let's solve it first by using the mixture formula, m1*c1+m2*c2=mf*cf with mf=m1+m2, m1*(1.0%)+(30g)*(2.5%)=mf*(2.0%), mf=m1+(30g). We have two equations and two unknowns. Removing all the percentages and solving by substitution, m1*1+75g=m1*2+60g, m1=15g, mf=30g+15g=45g. We need 15 grams of the 1.0% hydrocortisone cream.

Alligation: 1.0% is the lower strength, 2.5% is the higher strength, 2.0% is the desire strength. Place 2.5% in the upper left hand corner of our alligation grid, 1.0% in the lower left corner and 2.0% in the middle. The difference between the desire and lower is 1 part which goes into the upper right hand corner of the grid. The difference between the desire and higher is 0.5 part which goes in the lower right hand corner of the grid. The total parts for the desire strength is the sum of the higher part and the lower part, 1 and 0.5, respectively. Use proportion to find the weights of the lower strength, 0.5:1::X:30g, X=15g. We need 15g of the 1.0% strength hydrocortisone.

donna in Jonesborough, Tennessee said: I need help with this problem.

How much gentian violet is needed to prepare 100ml of a 1:10,000 solutin of gentian violet?

If anyone knows please show how to get the answer.

Use proportion to find the percentage of gentian violet in the 1:10,000 solution. 1:10,000::X:100mL, X=0.01, there are 0.01% of gentian violet in the solution. 100mL of a 0.01% solution is the same as 100mL*(0.01g/100mL) which equals to 0.01g or 10 mg. You need 10 mg of gentian violet to prepare a 100mL solution with concentration ratio of 1:10,000 or a 0.01% percent concentration.

samuel Boucher in Chandler, Arizona said: I am trying to figure this problem. I have to dilute 1g of powder to 330 mg/ml and give a 600 mg dose. I need to know how much diltent to add, how much to withdraw and what size syringe to use. I have never used or do I have a needle to know what size. I can problaby figure out the diluent to add

0.330g:1mL::X:100mL, X=33g, there is 33 grams of the powder in a 330mg/mL concentration. 1g:Y::33g:100mL, Y=3.03mL, you need 3.03 mL of diluent to dissolve the 1 gram powder. (1mL/330mg)*(600mg/dose)=1.8mL per dose, you need to draw out 1.8 milliliters of the diluted solution.

how many 500mg metronidazole tablest will be needed to compound 150ml of 3% meronidazole suspension?

150mL of 3% is equal to 150mL*(3g/100mL) which is equal to 4.5g, you need 4.5 grams of metronidazole to compound the suspension. 4.5g*(tab/0.5g)=9tab, you need nine 500mg tablets.

koolrvr31 in Wichita, Kansas said: Also, I know this is an aligation problem and thought I understand how to plug the numbers, but its not working out

It's not an alligation problem, the ingredients are not similar in type. Caffeine is not the same as aspirin nor is it an inert ingredient. Use alligations when you have the same ingredients but at different strengths. This is a proportional problem. Use proportions to solve ingredients problems containing three or more components in a mixture.

Linda Thompson in Tyler, Texas said: I really need help solving this problem and show me the formula on how you get the answer
a prescription is written for salicylic acid 1%, menthol 1/4% in triamcinolone0.1% cream. How much salicylic acid powder should be used if the prescription is for 240gm?
Thank You

1% of salicyclic acid is equal to 1 gram of salicyclic acid in 100 grams of cream, 1%=(1g/100g). Using proportion, 1g:100g::X:240g, X=2.4g, you need 2.4 grams of salicyclic acid in the 240 gram cream.
