Question

question 1 of 10
an iv solution of 570 ml at a drip rate of 20 gtt/min using a tubing factor of 15 gtt/ml has been ordered to be initiated at 1745. calculate the infusion time. (round your answer to the nearest tenth of an hour.)

Explanation:

Step1: Calculate total drops

Total drops = Volume × Tubing factor = \(570 \, \text{mL} \times 15 \, \text{gtt/mL} = 8550 \, \text{gtt}\)

Step2: Find infusion time in minutes

Infusion time (min) = Total drops / Drip rate = \(8550 \, \text{gtt} / 20 \, \text{gtt/min} = 427.5 \, \text{min}\)

Step3: Convert to hours

Infusion time (hr) = \(427.5 \, \text{min} / 60 = 7.125 \, \text{hr}\)

Step4: Round to nearest tenth

Rounded time = \(7.1 \, \text{hr}\)

Answer:

7.1 hr
