Show the answer and rationales

Answer: C

Intake includes IV fluids, piggybacks, flushes and all liquids, including foods that are liquid at room temperature such as gelatin. Ice chips count as half their volume. 1 oz = 30 mL.

  • A. Incorrect. This omits the two IV piggybacks (200 mL).
  • B. Incorrect. This omits the NG tube flushes (120 mL).
  • C. Correct. Correct. IV 600 + piggybacks 200 + coffee 240 + gelatin 120 + ice chips 120 (half their volume) + flushes 120 = 1,400 mL.
  • D. Incorrect. This counts the ice chips at their full volume (240 mL) instead of half.
