Answer 1

Ans 1) Order: Frusemide 80 mg p.o.b.i.d

Supply: Bottle containing 50 tablets of Lasix (Frusemide), 80 mg per tablet

p.o means per oral

b.i.d means twice per day but lasix is not administrated at bed time so timing should be written 8am & 4pm

As 1 tablet= 80 mg & order is 80 mg so 1 tablet should be administered orally at 8am & 1 tablet at 4 pm.

2) Order: Tamoxifen 0.02 g p.o b.i.d, morning & evening

Supply: Nolvadex (Tamoxifen) 20 mg per tablet

1 g = 1000mg

0.02= x mg

x= 20mg

As 1 tablet contains 20 mg & to administer 20mg ordered dose 1 tablet should be administered in morning & 1 tablet in evening.

3) Order: Depakene 375mg p.o. b.i.d

Supply: Depakene 250 mg/5ml

250mg = 5ml so 1ml = 50mg

To administer 375 mg:

50mg = 1 ml

375mg = x ml

x= 375/50 = 7.5 ml

4) Order: Amoxillin 0.375g p.o q8h

Supply: 125mg/5ml

q8h means 8th hrly or t.i.d

1g = 1000mg

0.375g= x mg

x= 375mg

So to administer the ordered dose:

125mg= 5ml

375mg= y ml

y= 15ml thrice in day
