Correct Answer is ["75"]
Explanation
Step 1: Identify the amount of formula in ounces. Result: 2.5 oz
Step 2: Convert ounces to milliliters using the conversion factor 1 ounce = 30 mL. Calculation: 2.5 oz × 30 mL/oz Result: 2.5 × 30 = 75 mL
Step 3: Round the result to the nearest whole number. Result: 75 mL (no rounding needed)
The nurse should document 75 mL as the intake on the I&O record.
Correct Answer is ["0.6"]
Explanation
Step 1: Determine the amount of enoxaparin in mg per mL. 60 mg ÷ 0.6 mL = 100 mg/mL
Result: 100 mg/mL
Step 2: Calculate the volume in mL needed to administer 55 mg. 55 mg ÷ 100 mg/mL = 0.55 mL
Result: 0.55 mL
Step 3: Round the result to the nearest tenth. 0.55 mL rounded to the nearest tenth = 0.6 mL
Result: 0.6 mL
The nurse should administer 0.6 mL of enoxaparin.
