Correct Answer is A

Explanation

To solve this problem, we need to find the concentration of heparin in the solution and then multiply it by the infusion rate. The concentration of heparin is the amount of heparin divided by the volume of the solution. In this case, the concentration is:

100,000 units / 1,000 ml = 100 units/ml

The infusion rate is given as 50 ml/hr. To find the flow rate in units/hr, we multiply the concentration by the infusion rate:

100 units/ml * 50 ml/hr = 5000 units/hr

Therefore, the flow rate in units/hr is 5000 units/hr.

Correct Answer is C

Explanation

Step 1: Identify the given information

  • Ordered dose = 1.0 mg
  • Available concentration = 0.4 mg per 1 mL

Step 2: Use the ratio and proportion method
Required dose ÷ Available concentration = Volume to administer

Step 3: Plug in the values
= (1.0 ÷ 0.4)

Step 4: Solve step by step

  • 1.0 ÷ 0.4 = 2.5 mL

Step 5: Round to the nearest tenth

  • 2.5 mL (already rounded)
