Explanation / Answer

16) The 0.25g of medication has to be given PO four times a day. The medication available is 150 mg/5ml.

5ml contains 0.15 mg. Therefore, the volume needed for 0.25g

= 0.25 x 5 / 0.15

= 8.33 ml

1 tsp contains 5ml

So, to make 8.33 ml, we need

= 1 x 8.33 / 5

= 1.67 tsp

17) The patient has to take medication for 2 weeks (14 days).

1 tablet contains 200mg of drug

So, inorder to have 400mg of drug per day, the patient has to take 2 tablets.

Therefore, in 14 days, the patient requires 28 tablets.

18) 1500 ml to be delivered in 12 hours

So, in 1 hour, it has to deliver 125 ml.

19) the drip factor is 60 gtt/ml

1 liter in 8 hours

So, 125 ml in 1 hour

2.08 ml per minute

1 ml contains 60 gtt

So, for 2.08 ml, 125 gtt is needed

Therefore, 125 gtt/min is needed.

20) The patient has to take tetracycline 0.75g PO

The medication is available in 250 mg tablets.

Therefore, the patient has to take 3 tablets to make 0.75 g.
