Explanation / Answer

14.Amount of epogen available = 2000units/ml

Amount ordered =1400units/ml

D/H*Q=1400/2000*1=0.7ml D=ordered dosage H=dosage in hand Q=quantity

15.Ordered dosage lasix=25mg

Dosage in hand Lasix=40mg

Quantity=4ml

Desired dosage= 25/40*4=2.5ml

23.Ordered dosage of ampicillin=500mg

Dosage in hand ampicillin=500mg

Quantity =250mg/ml so for 500 mg 2ml

500/500*2=2ml

24.Ordered dosage=500mg

Dosage in hand= 1g and after reconstitution 330mg/ml

Quantity=3ml

500/1000*3=1.5ml

25.Ordered dosage=Zosyn 2.5g

Dosage in hand = Zosyn 3.375 g

Quantity =5ml

2.5/3.375*5=3.7ml
