Which factors predominantly determine probable diagnosis of multiple sclerosis (MS)?
Muscle biopsies revealing characteristic lesions
Blood tests revealing identifiable MS markers
Lumbar puncture results revealing inflammatory response
Signs and symptoms assessed and reported by the patient
The Correct Answer is D
A. Muscle biopsies are not used to diagnose MS; they are more relevant in diagnosing muscle disorders, not central nervous system demyelination.
B. There are no definitive blood markers specific to MS; blood tests are mainly used to rule out other conditions.
C. A lumbar puncture may support a diagnosis by revealing oligoclonal bands or inflammatory markers, but it is not the primary determinant.
D. The diagnosis of MS is largely clinical, based on a combination of the patient’s history, reported symptoms (such as vision problems, weakness, and numbness), and neurological examination findings, often supported by MRI and other tests.

Correct Answer is A
Explanation
- Convert weight to kilograms:
82 lb ÷ 2.2 = 37.27 kg - Calculate safe dose range:
Minimum dose:10 mg × 37.27 kg = 372.7 mg/day
Maximum dose:12 mg × 37.27 kg = 447.24 mg/day
- Compare with ordered dose:
Ordered dose = 500 mg/day
Safe range = 372.7 mg to 447.24 mg/day
→ 500 mg exceeds the maximum safe dose (447.24 mg)
Final Answer:No, the order is not safe.
