A nurse is recording subjective information from the family of an aggressive client who was brought to the ED via ambulance. The client is non-compliant with the medication regimen. What statement by the family informs the nurse of their understanding of mental illness? "We know the intention was not to take medications, as it was relayed medication was not longer needed." "Because of mental illness, my brother cannot think clearly or understand the need for meds." "This situation occurs because of thoughts that no one cares and because it is getting attention." "The 'mental illness' has been used as an excuse to get away with his behavior for years."

The statement by the family that informs the nurse of their understanding of the client's mental illness is "Because of mental illness, my brother cannot think clearly or understand the need for meds".

Explanation:

Many mental diseases require the patient to use their medication correctly, to avoid the attacks that occur by omitting the indicated medical treatment. The same mental condition of a patient predisposes him to abandon the medication.

The fact that the family knows that, because of their mental condition and not thinking clearly, their relative is not taking their medication correctly and is having a crisis, lets the nurse know that they understand the client's illness.
