The client has an order for ketorolac 30 mg IV every 8 hours. The medication available is 80 mg/2 mL. How many mL will the nurse administer for each dose? (If needed, round to the nearest tenth.)
Answer Choices:
Correct Answer:
0.8
Rationale:
Have: 80 mg in 2 mL
Step 1: Find mg per mL
80 mg ÷ 2 mL = 40 mg/mL
Step 2: Use ordered dose
Ordered: 30 mg
Volume (mL) = Ordered dose ÷ Concentration
Volume = 30 mg ÷ 40 mg/mL
Volume = 0.75 mL
Step 3: Round to nearest tenth
0.75 mL ≈ 0.8 mL
