This patient with unintelligible but fluent speech most likely has Wernicke aphasia secondary to a stroke. Tissue plasminogen activator (tPA) is given to stroke patients as a form of tertiary prevention.

Prevention refers to interventions that decrease either the incidence, progression, morbidity, or mortality of a disease. These interventions can therefore be used in a public health perspective in order to mitigate the adverse effects of disease in a population. In particular, tertiary prevention refers to measures that are taken after the onset of symptoms for a disease and generally seek to decrease the morbidity associated with that disease. Good examples are the administration of medications after the onset of pathological states such as stroke, heart disease, and diabetes.

Incorrect Answers:
Answer 1: Primary prevention refers to measures taken in order to prevent the development of disease such as giving vaccinations to children before they have gotten an infection.

Answer 2: Secondary prevention refers to measures taken in order to detect a disease earlier before the onset of symptoms such as screening for cancer in all patients who fit certain demographic parameters.

Answer 4: Quaternary prevention refers to measures taken in order to decrease the adverse events associated with overtreatment of disease such as taking unnecessary biopsies.

Answer 5: Giving medications to reduce morbidity from a disease represents tertiary prevention.

Bullet Summary:
Tertiary prevention refers to measures that reduce morbidity from a disease after the onset of symptoms.
