Answer 1

9

1mg=100mcg

0.25mg = 0.25*1000 = 250 mcg

Each dose = 250 micrograms

10

1 inch = 25.4 mm

1.7 inch = 1.7*25.4 = 43.18 mm

Wound diameter = 43.18 millimeters

11

1 cup ~ 240 to 250 mL

1 hour = 60 minutes

4mL/min = 4*60 mL/hour = 240mL/hour ~ 1 cup/hour

Answer = 1 cup /hour

12

Dose = 50mg

Available compositions = 10mg, 20mg & 30mg

Though many combinations are possible, the easiest would be one 20mg and one 30mg tablet

13

Total dose = 50mg/kg * 40kg = 2000mg

Each dose = 2000/2 = 1000mg

Each tablet = 500mg

Hence each dose = 1000/500 = 2 tablets

14

t.i.d = 3 doses a day

Total dose = 50*3 = 150mg

150 mg is lesser than 225 mg

Hence the prescribed dose is Safe.
