So I was speeding through my pharm calculations from my Peds course pack before school starts next week and I found a section that has me stumped. I can't find anything like it in my pharm or Math for Meds book so I can't find a formula or way of solving these. Anyone have some insight on how I am supposed to figure these out? It'd be mighty helpful!
Ticarcillin is stable in solutions at room temperature for 1 hour. It can be give IV bolus over 10 minutes. If administered by burette, the flow rate for pediatric microdrip is: gtt/minute = mL/hour (60gtt = 1mL), Thus 60gtt/minute = 60mL/hour (or 60mL/60 minutes)"
6 - You're about to give the required dose using microdrip tubing. Considering the stability of ticarcillin and the volume to be infused, what's the minimum flow rate for safe administration? (From the previous problem I solved the volume is 12mL.)
7 - Given the time limit for the IV bolus method (10 minutes), what's the maximum flow rate you can use to deliver 12mL of ticarcillin with a concentration of 1Grams/5mL?
Flow rate consideration: You'll determine the appropriate IV flow rate based on several considerations, including the minimum amount of solution needed to infuse the drug, the patient's fluid restrictions, and how quickly the drug must be infused. You'll also take into account the patient's activity, any discomfort at the IV site, and other drug orders.
8 - You must administer 600mg of ticarcillin. What's the range for the IV flow rate?
9 - What's the time restriction on administering 600mg of ticarcillin to this child?
10 - How long would it take to infuse 600mg of ticarcillin in 12mL at a flow rate of 40gtt/minute?
11 - How long would it take to infuse 600mg in 15mL at a flow rate of 40gtt/minute?
12 - If you decide to give 600mg in 12mL over 20minutes, which flow rate would you use?
And they go on and on. Am I missing something? Am I supposed to be able to look up the IV flow rate range and stuff somewhere? There's lots more questions and this is NOTHING we went over in Pharm so I'm lost. Any direction would be helpful and thank you so much in advance!!!
