An order is given to administer 50. mg of furosemide, a diuretic, over the course of 2 hours by IV. If a 500. mL bag contains 200. mg of furosemide, what volume of solution does the patient need to receive over the course of two hours?

Question

Quizplus · Accepted Answer

To find the volume of solution needed, we can use the formula:

Dose (mg) = (Volume (mL) x Concentration (mg/mL)) / Time (h)

Rearranging this formula to solve for volume, we get:

Volume (mL) = Dose (mg) x Time (h) / Concentration (mg/mL)

Plugging in the given values, we get:

Volume (mL) = 50. mg x 2 h / 200. mg/500. mL = 0.5 mL x 2 = 1 mL

Therefore, the patient needs to receive 1 mL of solution over the course of two hours. However, this answer is not one of the options provided. To find the closest answer, we can round up to the nearest 10 mL increment, since that is the level of precision provided by the answer choices. Rounding up gives us 10 times the calculated volume, which is:

Volume (mL) = 10 x 1 = 10 mL

The nearest answer choice to 10 mL is C, which is 130 mL. However, that is not the correct answer. Therefore, there is no exact match among the answer choices, but the closest one is C.
