HEEEELLLLLLPPPPPP!!!!!!! dosage and calculations

[brains090]

I have been working on these problems for 3 hours now. The professors did not go over drops per minute calculations. Please help!

The label states to add 10ml sterile water for 1g of cefamandole for IV solutions

Order: cefamandole 500mg, IV, q6h

Set and solution: Calibrated cylinder with drop factor, 60 gtt/mL. 500ml of D₅W.

Instruction: Dilute cefamdole 500mg reconstituted solution in 50 mL of D₅W and infuse in 30 minutes. Determine gtt/min.

There's a lot of information in the question that you don't need. So let's start by eliminating the unnecessary words.

What is the total volume of the drug you're going to administer? The question did that math for you: 500mg of drug in 50mL of fluid. So 50mL is the volume you're going to give.

How quickly will you administer the drug? Again, this is provided for you: over 30 minutes.

Your tubing has a drop factors of 60gtt/mL. That means for every 60 drops, 1mL of medication will be given.

So now you can use the formula: (Volume in mL/time in minutes) x drop factor = drops per minute.
