Safe range 3.6 g/d - 4.5 g/d
No, the dose ordered is not within the safe range9. Patient weight 34 kg
Ordered dose 1200 mg/d
Safe range 1020 mg/d - 1700 mg/d
Yes, dose ordered is within the safe range10. Patient weight 30 kg
Ordered dose 200 mg loading dose
Safe dose 150 mg maximum loading dose
No, the ordered dose is not safe, it is 50 mg above the maximum loading dose.11. 14.5 kg * 40 mg = 580 mg/day ÷ 4 doses/day = 145 mg per dose
12. Convert oz to lb: 3 oz ÷ 16 oz/lb = 0.19 lb
Convert wt. to kg: 12.19 lb ÷ 2.2 = 5.5 kg
5.5 kg * 20 mg/day = 110 mg/day ÷ 3 doses = 36.67 mg per dose13. 3000 g = 3 kg
3 kg * 40 mg = 120 mg/day ÷ 4 doses = 30 mg per dose14. 8 kg * 100 mg/day = 800 mg/day ÷ 3 doses = 266.67 mg per dose
15. 20 kg * 1 mg/day = 20 mg/day ÷ 4 doses = 5 mg per dose is safe low dose and is dose ordered
Yes, the dose is in safe range.16. 10 kg * 80 mg/day = 800 mg/day ÷ 6 doses = 133.33 mg per dose (low safe dose)
10 kg * 160 mg/day = 1600 mg/day ÷ 6 doses = 266.67 mg per dose (high safe dose)
Yes, ordered dose falls within safe range.17. 72 lb ÷ 2.2 = 32.7 kg * 8 mg/day = 261.6 mg/day ÷ 4 doses = 65.4 mg per dose
18. Calculate mEq/hr being administered per order
mEq = 10 mEq = 2.5 mEq per hour hour 4 hours Calculate safe hourly dose
44 lb ÷ 2.2 = 20 kg * 3 mEq/24 hours = 60 mEq/24 hours
60 mEq : 24 hours = x mEq : 1 hour
x = 2.5 mEq per hourYes, the dose is safe because the hourly dose ordered is the same as the safe hourly dose.
19. 29.5 kg * 4 mg = 118 mg (low safe dose)
29.5 * 5 mg = 147.5 mg (high safe dose)
No the dose ordered is much higher and is not safe.20. 73 kg * 5 mcg = 365 mcg
