Chapter 18: Problem 15

Optic neuritis is the presenting symptom in what percentage of MS patients? a. \(10 \%\) b. \(20 \%\) c. \(30 \%\) d. \(40 \%\) e. \(50 \%\)

Short Answer

Expert verified
Answer: 20%

Step by step solution

01

Understand the question

The question is asking about the percentage of MS patients who first show optic neuritis as a symptom. We have 5 possible percentage options: 10%, 20%, 30%, 40%, and 50%.
02

Recall the correct value

From a study of the field, it's known that optic neuritis is the presenting symptom in about \(20 \%\) of MS patients.
03

Select the correct option

Since we now know the correct percentage, we can select the correct answer among the given options: a. \(10 \%\) b. \(20 \%\) c. \(30 \%\) d. \(40 \%\) e. \(50 \%\) The correct answer is option b, \(20 \%\).
