The healthcare provider has ordered 1000 mL of 0.9% sodium chloride to be administered intravenously over 5 hours. The drop factor on the tubing is 15 drops/mL. How many milliliters per hour and how many drops per minute will you administer?
Correct answer
1000 mL ├â┬À 5 hr = 200 mL/hr. 200 mL/hr ├â┬À 60 min = 3.33 mL/min ├âÔÇö 15 drops/mL = 49.95 drops/min, rounded to 50. Thus, 200 mL/hr and 50 drops/min.
Rationale
The correct answer is D: 200 mL/hr and 50 drops/min. To calculate the mL per hour, you divide the total mL by the total hours (1000 mL ├À 5 hr = 200 mL/hr). To find the mL per minute, you divide the mL per hour by 60 minutes (200 mL/hr ├À 60 min = 3.33 mL/min). Next, to determine the drops per minute, you multiply the mL per minute by the drop factor (3.33 mL/min ├ù 15 drops/mL = 49.95 drops/min, rounded to 50 drops/min). Therefore, the correct administration rate is 200 mL/hr and 50 drops/min.
Choices A, B, and C are incorrect because they do not align with the correct calculation based on the given parameters. Choice A and B have incorrect mL per hour values, and Choice C has an incorrect drops per minute value.
