Calculate the following dosage using the ratio and proportion method. Round the answer to the nearest tenth. Order: Heparin 17,000 units sub-cut daily
Available: Heparin labeled 20,000 units per mL
10ml
0.5ml
2.5 ml
0.9 ml
The Correct Answer is D
To solve this problem using the ratio and proportion method, we must set up a proportion with the ordered dose on one side and the available dose on the other. Then we cross-multiply and solve for the unknown quantity, which is the volume of heparin to be administered.
The proportion is:
17,000 units / x ml = 20,000 units / 1 ml Cross-multiplying gives:
17,000 * 1 = 20,000 * x
Solving for x gives:
x = 17,000 / 20,000
x = 0.85 ml
Therefore, the volume of heparin to be administered is 0.85 ml.
