ATI Pharmacology Exam 2 Questions

Extract:


Question 1 of 5

A nurse is preparing to infuse 1 liter of 0.99% sodium chloride IV over 8 hr with a tubing set that delivers 15 gtt/mL. The nurse should set the manual IV infusion to deliver how many drops/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, we first find the total volume in mL to be infused per minute: 1 liter over 8 hours is 125 mL/hr. Next, we convert this to drops using the drop factor (15 gtt/mL): 125 mL/hr multiplied by 15 gtt/mL equals 1875 gtt/hr. Finally, we divide by 60 to get gtt/min: 1875 gtt/hr divided by 60 min/hr equals 31.25 gtt/min. Since we must round to the nearest whole number, the correct answer is B (31 drops/min). Other choices are incorrect as they do not result from the correct calculation.
