Question

13 of 15
cva mortality rates have declined over the past 15 years. more than 75 percent of patients who have a cva(1 ) 1 year, and more than 50 percent survive for 5 years. some patients recover at least part of their lost faculties because undamaged (2 ) spread into areas where neurons have died and take over some lost functions. indeed, most of the recovery seen after brain (3 ) is due to this phenomenon
not all strokes are \completed\. temporary brain ischemia, or restricted blood flow, is called a transient (4 ) attack (tia). tias last from 5 to 50 minutes and are characterized by symptoms such as numbness, temporary paralysis, and impaired speech. although these (5 ) are not permanent, they do constitute
ed flags\ that warn of impending, more serious cvas.

1 injury 2 ischemic 3 defects 4 survive 5 neurons

1 ischemic 2 defects 3 survive 4 neurons 5 injury

1 neurons 2 injury 3 ischemic 4 defects 5 survive

1 defects 2 survive 3 neurons 4 injury 5 ischemic

1 survive 2 neurons 3 injury 4 ischemic 5 defects

Explanation:

1. "More than 75 percent of patients who have a CVA" implies we are talking about patients' survival status, so "survive" fits for (1).
2. Undamaged nerve - cells (neurons) can spread into damaged areas and take over functions, so "neurons" for (2).
3. Recovery is seen after brain "injury", which is a general term for the damage caused by CVA, so "injury" for (3).
4. "Transient ischemic attack (TIA)" is the correct medical term for temporary brain ischemia, so "ischemic" for (4).
5. Numbness, temporary paralysis, and impaired speech are "defects" or symptoms, so "defects" for (5).

Answer:

1. survive 2. neurons 3. injury 4. ischemic 5. defects
