Answer #1

ANSWER.

a) Pump setting in mL/hr.

Formula

Flow rate(ml/hr) = Volume(ml)/Time(hr)

Calculation of Volume(ml).

Formula = Desired dose/Dose in hand * Quantity.

Here

Desired dose(D) = 1.5 mg/min.

Dose in hand(H)= 150 mg.

Quantity(Q)= 200 ml.

As per formula

Volume = D/H * Q

=1.5/150 * 200

= 0.01 * 200

= 2 ml/min.

Multiply 60 minute(1hr) to ml/min to get ml/hr pump setting.

So

mL/hr = 2ml/min * 60

= 120 ml/hr.

b) IV finishing time.

IV begining time = 8 am.(0800 hours).

Amount of solution in the IV bag = 200 ml.

Flow rate(ml/min) = 2ml/min.

Time(hr) taken for finishing 200 ml = 200/2

= 100 min

= 1 hr 40 min.

So

IV finishing time = 8am + 1hr 40 min

= 9.40 am.
