Calculation
A nurse is caring for a client who has an NG tube set to low intermittent suction. The nurse irrigates the NG tube twice with 30 mL of normal saline solution during his shift. At the end of the shift, the NG canister contains 475 mL. What amount of NG drainage should the nurse record? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
mL
Explanation & Rationale
Calculation: Identify total measured output in the canister Total NG canister output: 475 mL Calculate total irrigation fluid instilled Irrigation: 30 mL × 2 = 60 mL Subtract irrigation from total output Actual NG drainage = 475 − 60 = 415 mL
