Question

A person that weighs 179 lbs needs an IV Drip in mL. The drug only comes in powder form but can be converted as 10 mg is equal to 2 mL. How much should the patient be given if they need at least 60 mg for each kg they weigh?

Answer 1

Solution:

Weight of person = 179 lbs

As given person needs IV Drip in m L.

Also,→ 10 mg = 2 m L

Now, you must remember , → 1 lbs = 0.453 Kg (approx)

→179 lbs = 179 × 0.453 Kg = 78.47 Kg (approx)

The person needs at least 60 mg for each Kg they weigh.

⇒ 1 Kg → 60 mg

⇒ 78.47 × 1 Kg → 78.47 × 60 mg

⇒ 78.47 Kg →  4708.2 mg

Also, 10 mg → 2 m L

⇒ 1 mg → $\frac{1}{5}$  m L

⇒ 4708 . 2 mg → $\frac{1}{5} \times 4708.2$  m L

⇒ 4708 . 2 mg → 941. 64 ml
