Please help with this problemThe patient is ordered levofloxacin 750 mg in 150 ml of d5w to infuse over 90 minutes. The client weighs 150lbs. Calculate the dosage in ml/hr.

Lipoma, BSN, RN 262 Posts Specializes in CEN | CCRN | ED and CICU. Has 5 years experience. Jul 14, 2018 Always read what the question is asking you to solve for. Skip the beginning so you don't confuse yourself with the distractors.For this example, you are solving for mL per hour or mL/hr. Now read the entire question. Now set up the equation in the order of what you are solving for (mL on top hr on bottom) with this being the first part of your equation. So: 150mL OVER 90 minutes (150mL/90 mins)...get rid of mins and convert to hr.150mL/90 mins x 60 mins/hr = 150 ml/90 x 60/hr = 9000 mL/90hr = 100 mL/hr

How have they tried to solve the problem rather than just to solve it for them.

Horseshoe, BSN, RN 5,879 Posts Jul 25, 2018 It's usually most helpful to ask what the student already knows. How have they tried to solve the problem rather than just to solve it for them.I agree. I really think it should be a TOS violation to just give someone the answer to a question.This is a pretty good example of how "help" should go:https://allnurses.com/general-nursing-student/i-cant-figure-1168609.html

TheDudeWithTheBigDog, ADN, RN 678 Posts Jul 25, 2018 Giving them the answer but walking them through how it's done is a good way to teach them how to do it though. Then knowing the answer, they can always go back and see if they're doing it right because they know what the answer should be.
