A nurse is preparing to administer 0.9% sodium chloride (NSS) 3000 mL IV to infuse over 24 hr. The drop factor on the manual IV tubing is 10 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.)
The Correct Answer is ["21"]
Total volume in mL: 3000 mL
Time in hours: 24 hours
Total volume to be infused in minutes: We need to convert hours to minutes. There are 60 minutes in 1 hour. Therefore, total time in minutes = 24 hours * 60 minutes/hour = 1440 minutes
Drop factor: 10 gtt/mL
Rate in mL/min: We can divide the total volume (mL) by the total time (minutes) to find the flow rate in mL per minute. Rate (mL/min) = 3000 mL / 1440 minutes = 2.08 mL/min (rounded to two decimal places)
Rate in gtt/min: To find the rate in gtt/min, multiply the rate in mL/min by the drop factor. Rate (gtt/min) = 2.08 mL/min * 10 gtt/mL = 20.8 gtt/min
Rounding the answer to the nearest whole number: 20.8 gtt/min rounds off to the nearest whole number to 21 gtt/min.

Correct Answer is B
Explanation
A. Developing atrial fibrillation can be a complication of hypothermia, but rewarming is still necessary to address the underlying condition.
B. Active rewarming should be discontinued if the patient's core temperature reaches 94°F (34.4°C), as further active rewarming could lead to complications. It's important to transition to passive rewarming methods to allow the patient's temperature to normalize gradually.
C. A decrease in blood pressure may indicate hypovolemia or shock but does not necessarily require discontinuation of rewarming.
D. Shivering is a normal response during rewarming and does not indicate a need to discontinue rewarming efforts unless other complications arise.
Correct Answer is ["5"]
Explanation
To calculate the infusion time for a 1-L bag of 0.9% sodium chloride at a rate of 200 mL/hr, you would divide the total volume of the IV bag by the hourly infusion rate. Since there are 1000 mL in a 1-L bag, you would calculate 1000 mL divided by 200 mL/hr, which equals 5 hours.
