Maths Formula

Can someone please help me solve these problems please.

13. An infusion of 500ml of Glucose 5% is to be given over 6 hours.
If using an infusion pump what rate would you set this at?.

Answer is in mls/hour.

14.Mr Jones requires a blood transfusion and has been prescribed one unit over 4 hours. The bag received contains 250mls.

Calculate the drops per minute. Remember: the drop factor when administering blood is 15 drops per ml.

15. Mr Jones requires a blood transfusion and has been prescribed one unit over 4 hours. The bag received contains 250mls.

If using an infusion pump what rate would you set this at?

For Infusion Pump the answer is in mls/hour.

16. A patient weighing 7kg needs 20mcg of Atropine per kg. The ampoule has 0.6mg in 1ml.

How many ml are required?

17. Vancomycin IV has been prescribed.

Calculate the volume required to reconstitute 250mg of dry powder Vancomycin, with a
displacement value of 0.2ml, to give a final concentration of 250mg/5ml?

18. Benzylpenicillin 600mg powder is to be reconstituted with 5ml of sterile water. The displacement value is 0.4ml/600mg.

What is the final volume if the displacement value is not taken into account?

19. Following on from the previous question, what then is the concentration in mg/ml?

20. If the displacement value was taken into account, the final volume would be 5ml. What then is the concentration in mg/ml?

21. A newborn baby weighing 3.4kg is to receive 25mg/kg of Cefotaxime every 12 hours. Cefotaxime 500mg is reconstituted with 2ml of sterile water. The displacement value for Cefotaxime is 0.2ml for a 500mg vial.

What dose of Cefotaxime does the baby need?

22. How much sterile water is needed to reconstitute a 500mg vial?

23. How much of this reconstituted solution do you need to administer to the baby?

24. Dopamine 200mg is diluted in 50ml of Glucose 5%. How many ml per hour is needed for a 30kg patient so that they receive 5mcg/kg/min?
These are really basic maths questions. I'll start with the first one, but you really do need to attempt them yourself, or we cannot see where you're stuck.

Answer is in mls/hour.

You want to give 500ml of fluid over 6 hours. How many ml per hour is that? (Hint: It's a sixth of the rate required to give it over 1 hour)
