Question 1 of 62

The primary healthcare provider (PHCP) prescribes 500 mL of 0.45% saline to be administered over one hour. The drop factor is 10 gtts/mL. How many drops per minute should the nurse set the flow rate at? Fill in the blank. Round your answer to the nearest whole number.

Correct Answer: 83 gtts/minute

Rationale: To calculate drops per minute, use the formula: (volume in mL × drop factor) ÷ time in minutes. Here, 500 mL × 10 gtts/mL = 5000 gtts, divided by 60 minutes = 5000 ÷ 60 ≈ 83.33, rounded to 83 gtts/minute.
