A nurse is preparing to infuse a 250-mL unit of packed RBCs over 2 hr. The drop factor of the manual IV tubing is 15 gtts/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.)
Correct answer
2
Rationale
The calculation involves dividing the total volume (250 mL) by the infusion time (120 minutes) and multiplying by the drop factor (15 gtts/mL). Simplified, this yields approximately 2 gtts/minute after rounding to the nearest whole number.
