Question

8. A doctor orders a patie octor orders a patient to receive Ampicillin IV at a rate of 50 mg/hour. The available solution contains 40 mg Ampicillin in 250 mL NS. (a) Determine the flow rate in drops per minute if the set calibration is 20 gtt/mL. (b) EXTRA CREDIT: Determine the dosage rate of NaCl the patient receives in mg per min.

Answer 1

Patient dose in ml Required dose volume Available dose soms & 250ml Hong = 312.5 melhour

So total 312.5 ml/hour

A) Drop factor fund rate in gts min - Volume & Doopfactor Gox Hass Hours - 31.2.5x20 GOXI = 104. lt stts/min drops - 1o4

How many drops per min,for that we have to apply to this formula,so will get 104 gtts/min.

B.Total 312.5 ml equal to 50 mg

So 1 ml is 50/312.5=0.16 mg

312.5 ml per hour is ns going

So per min 5.2 ml ns going

That means 5.2*0.16 =0.832 mg
