Correct Answer is ["26"]
Explanation
Step 1: Calculate the total dose per hour. 1.7 mg/min × 60 min/hr = 102 mg/hr Step 2: Determine the concentration of the solution. 1 g = 1000 mg 1000 mg = 250 mL 102 mg = (102 mg × 250 mL) ÷ 1000 mg = 25.5 mL/hr Step 3: Round to the nearest whole number. 25.5 mL/hr ≈ 26 mL/hr The IV pump should be set to deliver 26 mL/hr.
Correct Answer is ["12"]
Explanation
Step 1 is… (2 mcg/min) × (60 min/hr) = 120 mcg/hr Step 2 is… 1 mg = 1000 mcg, so 120 mcg/hr ÷ 1000 mcg/mg = 0.12 mg/hr Step 3 is… 0.12 mg/hr ÷ (1 mg/100 mL) = 12 mL/hr The final calculated answer is 12 mL/hr.
