Answer to Question 1

B
For 100 mL to infuse in 1 hour, divide 100 by 60 (minutes) to equal 1.66 mL per minute. At a drop factor of 15 gtt/mL, multiply 1.66 by 15, = 24.9 gtt/minute; round up to 25.

Answer to Question 2

B
Potassium chloride is an irritant that can traumatize the vein and stimulate the response of phle-bitis. When phlebitis is present, the vein feels hard and cordlike above the IV insertion site.
