NCLEX RN Dosage Calculation Questions Questions
Question 1 of 5
The nurse is calculating intake for a client. The client received: ,¢ One 100 mL intravenous antibiotic ,¢ One eight-ounce cup of ice chips ,¢ One eight-ounce cup of coffee ,¢ One eight-ounce cup of ice cream ,¢ Three eight-ounce cups of water. The nurse should calculate the client's total intake as how many mL? Fill in the blank.
Correct Answer: 1080 mL
Rationale: Convert ounces to mL: 8 oz = 240 mL. Ice chips count as half volume: 240 mL ÷ 2 = 120 mL.
Total: 100 mL (antibiotic) + 120 mL (ice chips) + 240 mL (coffee) + 240 mL (ice cream) + 720 mL (3 cups water) = 1080 mL.
