Question: A laboratory test shows that a patient has a viral load of 5,000 copies/mL. If the treatment reduces the viral load by 80%, what is the new viral load?

Options:

1,000 copies/mL
2,000 copies/mL
3,000 copies/mL
4,000 copies/mL

Correct Answer: 1,000 copies/mL

Solution:

An 80% reduction means that 20% of the original viral load remains. 20% of 5,000 copies/mL is 1,000 copies/mL.

A laboratory test shows that a patient has a viral load of 5,000 copies/mL. If the treatment reduces the viral load by 80%, what is the new viral load?

Correct Answer: 1000 copies/mL

Step 1: Identify the original viral load, which is 5,000 copies/mL.
Step 2: Determine the percentage reduction, which is 80%.
Step 3: Calculate the percentage of the viral load that remains after the reduction. Since 80% is reduced, 100% - 80% = 20% remains.
Step 4: Calculate 20% of the original viral load. To do this, multiply 5,000 copies/mL by 0.20 (which is 20% in decimal form).
Step 5: Perform the multiplication: 5,000 * 0.20 = 1,000 copies/mL.
Step 6: The new viral load after the treatment is 1,000 copies/mL.
