39. 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?
Answer: D
The total IV fluid the patient should receive is 868.3 mL.
To determine the new total IV fluid amount, the current volume of 755 mL must be increased by 15%. This calculation results in a total of 868.3 mL when rounded to the nearest tenth.
A) 755.75
This option reflects a slight increase over the current volume but does not account for the required 15% increase. It is incorrect because it fails to calculate the correct adjustment based on the physician's order.
B) 770.25
While this option shows an increase, it is significantly lower than the required new total. A 15% increase on 755 mL would result in a much higher amount, rendering this option incorrect.
C) 800.6
This choice indicates an increase, but it still falls short of the necessary total. It does not accurately reflect the 15% increase from the original volume of 755 mL, making it an incorrect option.
D) 868.3
This is the correct answer. It accurately reflects a 15% increase from 755 mL, resulting in a total of 868.3 mL when calculated properly and rounded to the nearest tenth.
Conclusion
The correct answer, 868.3 mL, is derived from a precise calculation of a 15% increase on the original 755 mL. All other options fail to meet the requirement set by the physician's orders, either by being too low or not correctly applying the percentage increase needed. Thus, option D is definitively the right choice.
