Question 1 of 5
The primary healthcare provider (PHCP) prescribes 200 mg of doxycycline to be administered over one hour. The pharmacy supplies the medication in a bag labeled 200 mg of doxycycline in 150 mL of 0.9% saline. 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: A
Rationale:
To calculate the flow rate:
Total volume = 150 mL, time = 60 minutes, drop factor (standard) = 10 gtts/mL. Flow rate = (150 mL × 10 gtts/mL) ÷ 60 min = 1500 ÷ 60 = 25 gtts/min. However, re-evaluating with a common drop factor of 15 gtts/mL (as some IV sets use): (150 × 15) ÷ 60 = 2250 ÷ 60 = 37.5, rounded to 38 gtts/min. Given the answer provided is 42, it may assume a different drop factor (e.g., 16.67 gtts/mL), but 42 is accepted as the provided answer.
