A nurse is preparing to administer 400 mL of 0.9% sodium chloride IV over 8 hr. The drop factor of the manual IV tubing is 60 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.)
Correct answer
B
Rationale
Using the formula Flow rate (gtt/min) = (Volume/Time) × Drop factor, 400 mL / (8 × 60) × 60 gtt/mL = 50 gtt/min.
