Final answer:
Mrs. Anderson's heightened nervous excitability does not make her permanently unfit, as her condition is seen as temporary and recoverable by Drayton, her doctor. Her doctor's plan suggests consistency in treatment, aiming for full recuperation.
Step-by-step explanation:
The question pertains to determining whether Mrs. Anderson's mood swings make her unfit and if her doctor is suggesting a similar treatment approach as previously mentioned. Based on the provided excerpts, Mrs. Anderson exhibits heightened nervous excitability and restlessness. Drayton, presumably her doctor, notes these nervous natures recover swiftly and anticipates that the illness will leave no lasting impact. Furthermore, another excerpt reveals that a patient improved significantly with rest, bolstering the belief in recuperative powers. The provided text shows an understanding of the temporary nature of such ailments and suggests a level of competence in dealing with them.
The doctor's treatment plan seems to be consistent, aiming to stabilize the patient's condition with hopes of a full recovery. Mrs. Anderson's condition does not necessarily render her unfit, as the doctor anticipates a swift comeback to normalcy. Therefore, a sudden bout of ill mood or a mental disorder does not equate to permanent unfitness, and the doctor is offering a regimen that he believes will result in a complete recuperation.
