Answer 1

18. Solution:

Step 1:

Mannitol 20% in 500mL solution.

Amount of mannitol in 500mL = 500 X 20 / 100

= 100g

Amount of mannitol is 100g in 500mL.

Step 2:

Calculate the Amount of mannitol to be administered

Amount = Ordered dose / Dose on hand X Quantity

Ordered dose = 30g

Dose on hand = 100g

Quantity = 500

Amount = 30 / 100 X 500

= 150mL

The patient's receive 150mL of mannitol.
