A nurse is preparing to administer 0.9% sodium chloride 1,200 mL IV to infuse over 24 hr. The drop factor of the 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.)
Correct answer
B
Rationale
To calculate the drops per minute (gtt/min) for the IV infusion, we first need to determine the total drops needed over 24 hours.
1200 mL to infuse over 24 hr = 1200 mL/24 hr = 50 mL/hr.
Convert 50 mL/hr to drops: 50 mL x 15 gtt/mL = 750 gtt/hr.
Now, convert gtt/hr to gtt/min: 750 gtt/hr ├À 60 min/hr Ôëê 12.5 gtt/min.
Rounded to the nearest whole number, the correct answer is B: 13 gtt/min.
Other choices are incorrect because they do not reflect the accurate calculation based on the drop factor and infusion rate.
