Correct Answer is ["415"]
Explanation
To calculate the amount of NG drainage, the nurse should subtract the amount of irrigation fluid from the amount of fluid in the NG canister. The irrigation fluid is not part of the drainage, but rather a way to keep the NG tube patent and prevent clogging.
The amount of irrigation fluid is 30 mL x 2 = 60 mL.
The amount of fluid in the NG canister is 475 mL.
Therefore, the amount of NG drainage is 475 mL - 60 mL = 415 mL.
The answer should be rounded to the nearest whole number and use a leading zero if it applies. Do not use a trailing zero.
Therefore, the final answer is 415 mL.
