Calculation
A nurse is preparing to infuse 250 mL of packed RBCs over 2 hr. The drop factor of the IV tubing is 15 gtt/mL. The nurse should adjust the flow rate to deliver how many drops per minute? (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
Step 1: mL ÷ 2 hr = 125 mL/hr Step 2: (125 mL/hr × 15 gtt/mL) ÷ 60 min/hr = 31.25 gtt/min Step 3: Round to the nearest whole number = 31 gtt/min. Final answer: 31 gtt/min.
