The physician has ordered a patient's IV fluid to be increased by 0.15 (15%). The individual is currently receiving 755 mL every six hours. How much total IV fluid should the patient receive under these new orders, rounded to the nearest tenth?

Rationale

The patient should receive a total of 868.3 mL of IV fluid under the new orders.

To calculate the new total IV fluid amount, first, we determine the increase by finding 15% of the current 755 mL. This results in an additional 113.25 mL, which, when added to the original volume, gives a total of 868.25 mL, rounded to 868.3 mL.

A (755.75) YOUR ANSWER

This choice does not account for the 15% increase in IV fluid. It merely reflects a slight increase over the original 755 mL, but fails to include the full 15% increase required by the physician's orders.

B (770.25) YOUR ANSWER

This option incorrectly calculates the increase as 15% of 755 mL. The increase of 15% should yield 113.25 mL, leading to a total of 868.25 mL, not the lower value suggested here. Therefore, this choice is significantly less than the required total.

C (800.6) YOUR ANSWER

While this value is an increase from the original volume, it does not correctly reflect the 15% increase of the original 755 mL. This underestimates the required total as well, as the accurate increase leads to a total much higher than 800.6 mL.

D (868.3) CORRECT

This is the correct calculation. After determining that 15% of 755 mL is 113.25 mL and adding that to the original 755 mL, we find that the new total is indeed 868.25 mL, which rounds to 868.3 mL.

Conclusion

To summarize, the physician's order requires a calculation of a 15% increase on the patient's current IV fluid, leading to a total of 868.3 mL. The other options fail to appropriately calculate this increase, reflecting either miscalculations or insufficient increases. Understanding the arithmetic involved is essential for ensuring proper patient care.
