单选题 A client is prescribed 1000 mL of an antibiotic solution to be given over 6 hours. What would be the flow rate? The infusion set administers 15 gtts/mL.

A. 28 gtts/min.
B. 35 gtts/min.
C. 42 gtts/min.
D. 45 gtts/min.

【正确答案】 C

【答案解析】The IV flow rate is determined by the rate of infusion and the number of drops/mL of the fluid being administered. Flow Rate = (Volume×Calibration) /Time (minutes). In this case, the Rate=15gtts/mL×1000mL/360min=42gtts/min.
