The physician has ordered an IV infusion of 1000 mL DSW 45% normal saline (NS) to be administered over 8 hours. Tubing drop factor is 10 gtts/ml. How many gtts/min will the nurse administer? (Round answer to whole number: LABEL CORRECTLY)
The Correct Answer is ["21"]
Total volume = 1000 mL over 8 hr → mL/hr = 1000 ÷ 8 = 125 mL/hr.
Drops/min = (mL/hr × drop factor) ÷ 60 = (125 × 10) ÷ 60 = 1250 ÷ 60 = 20.833…
Rounded to whole number = 21 gtts/min.
Correct answer: 21 gtts/min.
