Answer 1

19. Prescription of heparin 1250 units/hour

Solution to be infused is 50,000 units/ 1000 ml

1 ml solution = 50,000 $\div$ 1000

                    1 ml = 50 units heparin

Volume of solution = 1250 $\div$ 50

                              = 25 ml

Drop factor is 60 gtt/ ml

Rate of drops per minute = 25 ml $\div$ 60 minutes $\times$ 60 gtt = 25 gtt/min

The patient should be administered with 25 drops per minute

20. Prescription of Magnesium sulfate 4 gm intravenously for 20 minutes

Availability of medicine is 40 gms/ 1000 ml

Per hour 12 grams of magnesium sulfate to be infused

Each gram of magnesium sulfate is present in 25 ml of solution (1000$\div$40)

The patient needs 12 grams per hour that is 12gms $\times$ 25 ml = 300 ml

The infusion pump should be set to 300 ml/ hr

21. Prescription of Pitocin infusion 16 mu/min

Availability of medicine is 10 units in 500 ml of D5LR

1 unit = 1000 milliunits (10,000 mu in 500 ml D5LR)

Per hour 16 mu $\times$ 60 min that is 960 mu of Pitocin to be infused in one hour

One milliunit of Pitocin is present in 0.05 ml of D5LR (500 $\div$10,000)

The patient needs 960 mu per hour that is 960 $\times$ 0.05 = 48 ml

The infusion pump should be set to 48 ml/hr

22. Prescription of Pitocin infusion 6 mu/min

Availability of medicine is 10 units in 500 ml of D5LR

1 unit = 1000 milliunits (10,000 mu in 500 ml D5LR)

Per hour 6 mu $\times$ 60 min that is 360 mu of Pitocin to be infused in one hour

One milliunit of Pitocin is present in 0.05 ml of D5LR (500 $\div$10,000)

The patient needs 360 mu per hour that is 360 $\times$ 0.05 = 18 ml

The infusion pump should be set to 18 ml/hr
