Answer 1

2) ordered : 1.6 mg Pancuronium

In the question, it is given that available dose of Pancuronium is 2 mg/ml

i.e, 2 mg Pancuronium is present in 1 ml.

But the required dose is 1.6 ml

2 mg Pancuronium ➡️1 ml

1.6 mg Pancuronium ➡️ 'X' ml

X = 1.6 mg ×1 ml ÷ 2 mg

= 0.8 ml.

so the required dose of Pancuronium is 0.8 ml.

3) Ordered Heparin dosage = 3500 units, SC

Available Heparin is 5000 units/ml

i.e, 5000 units of heparin in 1 ml.

So the required dosage is :

5000 units ➡️1 ml

3500 units ➡️ 'X' ml

X = 3500 units × 1 ml ÷5000 units

= 0.7 ml.

So the required dose of heparin is 0.7 ml.

4) Ordered dose : 45,000 units in 500 ml D5W.

Available 10,000 units/ml

i.e, 10,000 units in 1 ml of solution.

The amount to be added in IV is :

10,000 units➡️1 ml

45,000 units ➡️ 'X' ml

x = 45,000 units × 1ml ÷ 10,000 units

= 4.5 ml

So 4.5 ml of Heparin should be added to 500 ml D5W.

5) Ordered Augumentin dosage is 200 mg

Available dosage : 125 mg/5 ml

i.e, 125 mg Augumentin is present in 5 ml solution.

The required amount of solution is :

125 mg ➡️ 5 ml

200 mg ➡️ X ml

X = 200 mg × 5 ml ÷ 125 mg

= 8 ml

So 8 ml of Augumentin solution should be administered .

6) Ordered 1000 ml normal saline / 12 hrs.

Drop factor : 15 gtt /ml.

Drip rate.???

1000 ml saline ➡️ 12 hr

X ml saline ➡️ 1 hr

X = 1000 ml × 1hr ÷ 12 hrs

= 83.4 ml /hr.

83.4 ml saline is given for 1 hr.

The amount saline/minute = 83.4 ml /60

= 1.4 ml /min.

Given drop factor is 15 gtt / ml.

i.e, 15 drops ➡️ 1 ml

X drops ➡️ 1.4 ml

X = 1.4 ml × 15 drops ÷ 1 ml

= 21 drops.

So the drip rate is '21 drops/min' which is equal to ' 1.4/ min '

7) Ordered : Vancomycin 1gm in 250 ml NS for 1 hr

Drop factor 10 gtt/ml

Drip rate.????

250 ml NS with 1gm vancomycin ➡️ 60 min (1hr)

X ml. ➡️ 1 min

X = 250 ml × 1 min ÷ 60 min

= 4.2 ml /min.

Given,

Drop factor 10 drops ➡️ 1 ml

'X' drops ➡️ 4.2 ml

X = 4.2 ml ×10 ÷ 1 ml

X = 42 drops.

So the drip rate is '42 drops / min ' which is equal to 4.2 ml/min.

8) Ordered Morphine sulfate 6mg

Available : 10mg /1 ml

i.e, 10 mg morphine sulfate in 1 ml solution.

But the required amount is 6 mg .

So,

10 mg morphine sulfate ➡️1 ml

6 mg Morphine sulfate ➡️ x ml

X = 6 mg × 1ml ÷ 10 mg

= 0.6 ml

So 0.6 ml of morphine sulfate solution is administered.

9)Ordered 450 mg

Available : 250 mg / 15 ml

i.e, 250 mg drug in 15 ml solution.

So,the required amount is :

250 mg ➡️15 ml

450 mg ➡️X ml

X = 15 ml × 450mg ÷ 250 mg

= 27 ml

so 27 ml of the solution is administered.

10) Ordered : 0.25 mg

Available : 0.5 mg in 2 ml

So the amount of solution to be administered is :

0.5 mg ➡️ 2 ml

0.25 mg ➡️ 'X' ml

X = 2 ml × 0.25 mg ÷ 0.5 mg

= 1 ml.

So 1ml of Digoxin should be administered.

11) Ordered : 8 mg Ampicillin

Available : 125 mg Ampicillin in 25 ml solution

So the amount of solution to be administered is :

125 mg Ampicillin➡️ 25 ml

8 mg Ampicillin ➡️ X ml

X = 25 ml× 8mg÷ 125 mg

X = 1.6 ml

So, 1.6 ml of Ampicillin is administered.
