If 500 mL of D5W is infused at a rate of 60 mL/hr, how long will the infusion take?

To determine how long it will take to infuse 500 mL of D5W at a rate of 60 mL/hr, you need to use the formula:

Time (in hours) = Total Volume (in mL) ÷ Rate of Infusion (in mL/hr)

Plugging in the values:

Time = 500 mL ÷ 60 mL/hr

Calculating this gives:

Time = 8.33 hours

It's important to note that this value is not directly matched with the options given. However, if rounded down to the nearest whole number, it can be misleading to suggest that it's 6 hours, as it clearly takes more time.

Analyzing the option that indicates a duration of 6 hours suggests a misunderstanding of the rate versus total volume; at 60 mL/hr, the infusion can’t possibly complete in 6 hours given the total volume available.

The correct choice reflects a longer duration than initially implied and ensures clarity in interpreting the calculations, which confirms that the answer indicating 8 hours aligns closely with the calculated expectation of the infusion duration.
