What this question is testing

Objective: Measurement and Documentation

Prompt focus: A nursing assistant is recording a resident's intake and output. The resident drank a 240 mL carton of milk and 120 mL of juice, and voided 350 mL of urine. How should this be documented?

Why the correct answer works

Intake 360 mL and output 350 mL

Adding the milk and juice gives 360 mL intake, and the voided urine of 350 mL is the output.

Why the tempting wrong answer fails

This reverses the intake and output values; intake is 360 mL and output is 350 mL.

Plain-language takeaway

Intake includes all fluids the resident consumed, so 240 mL of milk plus 120 mL of juice equals 360 mL of intake. Output includes fluids the body eliminates, so the 350 mL of voided urine is recorded as output.

Simple analogy

Think of measurement and documentation like following a short checklist: identify the clue, confirm the rule, and then make the move that fits this exact scenario.

How to review it before a retake
