solve using dimensional analysis
Homework Answers
ANSWER.
17) Calculation of time required for the infusion to complete.
Rate(ml/hr) = Total volume(ml) / Time(hr).
Time(hr) = Total volume(ml) / Rate(ml/hr).
Calculation of volume(ml).
Formula = Desired dose/Dose in hand *Quantity.
Ordered dose = 0.1 unit/kg/hr.
Weight of the patient = 46 kg.
Desired dose(D) for this patient = 0.1 * 46
= 4.6 unit / hr.
Dose in hand(H) = 100 unit
Quantity(Q) = 500 ml.
As per above formula
Volume required = 4.6 / 100 * 500
= 0.046 * 500
= 23 ml.
Rate = 23 ml /hr.
Time(hr) = Total volume(ml) / Rate(ml/hr)
= 500/ 23
= 21.7
= 22 hr (Time required to complete the infusion).
