Question

A resident's chart asks for her fluid intake in milliliters for the day shift. She drank 8 oz of water at the bedside and 12 oz of tea during an afternoon visit. The unit nurse had already written down a 250 mL supplement drink. What is the resident's total fluid intake for the shift? Use 1 fl oz = 30 mL. Give the total in mL.

  1. 270 mL✗ Incorrect

    Incorrect. This answer adds ounces and millilitres without converting.

  2. 600 mL✗ Incorrect

    Incorrect. This answer leaves out the amount already in mL.

  3. 750 mL✗ Incorrect

    Incorrect. This answer uses 25 mL per ounce.

  4. 850 mL✓ Correct

    Correct. (8 + 12 + 0) oz × 30 mL/oz + 250 mL = 850 mL.

Answer

D. 850 mL

Rationale

Intake is charted in one unit so the nurse can add shifts together and compare intake with output. Amounts measured in ounces are converted first, and the amount already recorded in milliliters is carried over as it is. Adding ounces and milliliters together without converting is a common slip that makes the total wrong.

Worked solution: (8 + 12 + 0) oz × 30 mL/oz + 250 mL = 850 mL.

RememberChart fluids in mL: convert any ounces, then add what is already in mL.
