Calculation
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.)
gtt/min
Explanation & Rationale
Calculation: Total volume (mL) = 400 mL Total time (hr) = 8 hr = 480 min Drops per minute (gtt/min) = (Total volume × Drop factor) / Total time gtt/min = (400 mL × 60 gtt/mL) / 480 min = 50 gtt/min
