Correct Answer is ["12.8"]
Explanation
Step 1: Patient weight = 75 kg
Step 2: Current order = 15 units/kg/hr
→ 15 × 75 = 1125 units/hr
Step 3: Adjustment based on aPTT = 43 sec (range 35–45 sec)
→ Rebolus with 40 units/kg and increase rate by 2 units/kg/hr
Step 4: New rate in units/kg/hr
15 + 2 = 17 units/kg/hr
Step 5: Convert to total units/hr
17 × 75 = 1275 units/hr
Step 6: Concentration of solution
25,000 units ÷ 250 mL = 100 units/mL
Step 7: Convert to mL/hr
1275 ÷ 100 = 12.75 ≈ 12.8
Final Answer:12.8
