A client is prescribed 1000 mL of normal saline to infuse over 24 hours. At what rate should the nurse
set the pump (mL/hr) to deliver this infusion? (Record your answer using a whole number.) ____ mL/hr -
Answer 42
XmL/hr=
1000 mL ÷ 24 hours = 41.6 rounded to 42 mL/hr
A client is prescribed 250 mL of normal saline to infuse over 4 hours via gravity. The facility supplies
gravity tubing with a drip factor of 15 drops/mL. At what rate (drops/min) should the nurse set the

Xdrops/min=
4 hours x 60 mins = 240 mins
250 mL ÷ 240 mins = 1.04166666667 x 15 drops=15.625 rounded to 16 drops/min
A nurse assesses a 66-year-old client who is attempting to quit smoking. The client states, "I started

(Record your answer using a whole number, and rounding to the nearest drop.) _____ drops/min -
Answer 31
