Verbal

Restless legs syndrome also known as Willis-Ekbom disease is characterized by an irresistible urge to move one’s legs, particularly during sleep. Several widely consumed pharmaceutical agents have been shown to reduce symptoms of restless leg syndrome, but those same agents are also associated with a range of side-effects, many of which are quite common, and some can be quite serious. While offsetting treatments can reduce or even eliminate the side effects associated with pharmaceutical agents designed to treat restless leg syndrome, some form of side effect is unlikely to be prevented.

The information above most strongly supports which one of the following?

Ⓐ All restless leg syndrome patients taking a pharmaceutical agent should also take an offsetting treatment.

Ⓑ Side effects suffered by a restless leg syndrome patient can be attributed to a failure to also take an offsetting treatment.

Ⓒ At least some restless leg syndrome patients suffer from side effects as a result of a pharmaceutical agent.

Ⓓ Restless leg syndrome patients who want to avoid side effects from a pharmaceutical agent should take an offsetting treatment.

Ⓔ Doctors and specialists should refrain from prescribing a pharmaceutical agent to treat restless leg syndrome if that patient could contract a side effect as a result.
