Question

The physician ordered Calcium Gluconate 2,000 mg IVPB to infuse over 2 hours. The patient currently has an IV of D5 1/2NS infusing @ 50 gtt/min. The drop factor is 20 gtt/ml. The IVPB bag to which you will add the Calcium Gluconate is Normal Saline and has a volume of 50 ml. The 10 ml multidose vial states, “Calcium Gluconate 25%.”

A. What is the flow rate (ml/hr) of the D5 1/2NS?

B. What volume of medication will you remove from the multidose vial to add to the IVPB solution?

C. What is the drip rate (gtt/min) for the Calcium Gluconate?

Answer 1

The patient currently has an IV of D5 1/2NS infusing @ 50 gtt/min.

The drop factor is 20 gtt/ml

A.

/min

So, per hour it will be

Answer - The flow rate of D5 1/2NS is 150ml/hr

B.

The IVPB bag to which you will add the Calcium Gluconate is Normal Saline and has a volume of 50 ml. The 10 ml multidose vial states, “Calcium Gluconate 25%.”

Order dose =  Calcium Gluconate 2,000 mg IVPB to infuse over 2 hours.

2000mg=2g

So,

We need 8 ml of Calcium gluconate from the multidose vial.

C.

Now, we have to administer 58ml in 2 hour

The drop factor is 20 gtt/ml

So,

(10 drops per/min)

Answer - drip rate for the Calcium Gluconate is 10gtt/min
