Question 1 of 5
A nurse is calculating the fluid intake for an infant at the end of an 8-hr shift. For oral intake, the infant had 10 mL of medication, 3 oz of formula, and 2 oz of juice. In addition, the infant had IV fluid infusing at 20 mL/hr via an IV pump. The nurse should record how many mL of intake on the clients record? (Round the answer to the nearest whole number.)
Correct Answer: C
Rationale: Formula = 3 × 30 = 90 mL, Juice = 2 × 30 = 60 mL, Oral = 10 + 90 + 60 = 160 mL, IV = 20 × 8 = 160 mL.
Total = 320 mL.
