Question

a nurse is preparing to administer lactated ringers 2 l iv to infuse over 16 hr. the drop factor of the manual iv tubing is 10 gtt/ml. the nurse should set the manual iv infusion to deliver how many gtt/min? (round the answer to the nearest whole number. use a leading zero if it applies. do not use a trailing zero.)

Explanation:

Step1: Convert liters to milliliters

Since \(1L = 1000mL\), then \(2L=2\times1000 = 2000mL\).

Step2: Calculate the total number of minutes

Given the infusion time is \(16\) hours. Since \(1\) hour \(= 60\) minutes, then the total time in minutes is \(16\times60=960\) minutes.

Step3: Use the formula for gtt/min

The formula for calculating the drip rate (\(gtt/min\)) is \(\text{Drip rate}=\frac{\text{Volume}(mL)\times\text{Drop factor}(gtt/mL)}{\text{Time}(min)}\).
Substitute the values: \(\text{Volume} = 2000mL\), \(\text{Drop factor}=10gtt/mL\), \(\text{Time}=960\) minutes.

Step4: Round to the nearest whole number

Rounding \(20.83\) to the nearest whole number gives \(21\).

Answer:

\(21\)
