Question

a nurse is preparing to administer dextrose 5% in water (d,w) 1 l iv to infuse over 12 hr. the drop factor of the manual iv tubing is 15 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 volume and time units

First, convert \(1\space L\) to \(mL\) (\(1\space L = 1000\space mL\)) and \(12\space h\) to \(min\) (\(12\times60 = 720\space min\)).

Step2: Apply the IV flow rate formula

The formula for manual IV flow rate (\(gtt/min\)) is \(\text{Flow rate}=\frac{\text{Volume}(mL)\times\text{Drop factor}(gtt/mL)}{\text{Time}(min)}\).
Substitute the values: \(\frac{1000\times15}{720}\).
Calculate \(1000\times15 = 15000\), then \(15000\div720=\frac{15000}{720}=\frac{125}{6}\approx20.83\).

Answer:

\(21\)
