Administer Neosynephrine 10 mg in 500 ml NS for a pt in septic shock. Infusion rate = 15 ml/hr. What's the corresponding dosage in mcg/min

Back 29

5 mcg/min
1 Change flow rate from ml/hr to ml/min (15 ml/hr to 15/60 min=0.25 ml/min)
2 Change mg to mcg so 10 mg=10,000 mcg
10,000 mcg in 500 ml of NS
D/H (Q)=R
x/10,000 (500)= 0.25 ml/hr
multiply by 10, 000 mcg on each side & you have
x(500)=2,500
Divide 500 ml from both sides
2500/500=5 mcg

Back 59

8.1 g



Calculate amount of sodium chloride in 0.0018 kL 1/2 NS.
Recall NS is 0.9% NaCl (sodium chloride)
0.9 * (1/2) = 0.45%
Concentration %
100
x Volume (mL) = Y (Dosage Amount in g)
Convert 0.0018 kL to mL.
mcL ← mL ← L ← kL ( x by 1,000 )
0.0018 kL x 1,000 x 1,000 = 1,800 mL
0.45%
