Help me please, med math problem with IV

[BrendaKarenMorgul]

I have been trying to figure out a med math problem, please help me understand this.

my exam is Thursday

Doctors order: 50 mg IV STAT

I have a vial of DimenhyDRINATE that reads 50mg/ml. What is the withdrawable amount of fluid you would need for this order?

I put 1o mL

Which type of solution will I use to mix this medication?

I put 0.9% NaC1

what is the minimal amount of time to infuse the medication?

I put 30min

then the question goes onto say Using an IV pump, my pt has NS 1 L on the primary line infusing at 250 mLs/hr. The secondary line is for me to hang my Gravol, describe what I would set the following to on my pump:

Mode: Piggy Back or Concurrent and describe what means?

Rate:

VTBI:

Duration:

Using gravity, calculate the drip rate of my primary line (250 mL/hr of NS) and secondary Line (Gravol).

please help I am so frustrated I've been trying to figure this out for over 2 hours now...

thank you all....

Kind Regards

they let LVNs do IVs? anyways i will try to help u out.

its order/hand so that would be order= 50mg and what u hav in hand is = 50mg/1ml (vial). so its 50mg/50mg per 1 ml. so both 50mg cancel out u get 1 ml. so u would draw 1 ml. in that 1 ml there is DimenhyDRINATE 50mg mixed in with it which is what the doctor wanted. the minimal amount time u can find that in ur drug book i think. now u put this 1 ml in ur secondary line (piggy back). now for the rate it depends on what the drug book tells u. lets says the drug book said 30 mins. so its 1 ml in 30 mins. the rate is usually set per hour. so to figure out the rate u can simply multiply it by 2 because 30 mins x 2 = 1 hr so 2 x (1ml in 30 mins) would be 2ml in 1 hr. so that would be ur rate 2ml/hour. VTBI (volume to be infused) would be 1ml. duration would be 30 mins i think
