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 C
Explanation
A. Pediculicide lotions are used to treat lice, not ticks. They are not effective or appropriate for tick removal.
B. Twisting a tick during removal can cause the mouthparts to break off and remain embedded in the skin, increasing the risk of infection.
C. Grasping the tick as close to the skin as possible with fine-tipped tweezers allows for complete removal without squeezing the tick's body.
D. Using a hot ember or match tip can cause the tick to regurgitate into the skin, increasing the risk of disease transmission.
Correct Answer is B
Explanation
A. Reviewing the client's medical record is important for understanding their health status but is not directly related to investigating an injury claim at the workplace.
B. Reviewing the workplace procedures and protocols manual is crucial to understanding the standards and practices relevant to the injury claim.
C. The Occupational Safety and Health Act provides guidelines and regulations for workplace safety but does not provide specific details about individual injury claims.
D. The client's attendance record at health and safety seminars may be informative but is less directly relevant to investigating the injury claim compared to reviewing workplace protocols.
