answers
An |example |of |inappropriate |treatment |for |head |trauma |would |be:
A. |Head |elevation |
B. |Free |water |restriction |
C. |hypoventilation
D. |Bed |rest |- |correct |answer | |hypoventilation |
***hypoventilation: |
Rationale: |Maintaining |adequate |oxygenation |is |crucial |for |brain |function |and |recovery. |Therefore, |
hypoventilation |is |considered |inappropriate |as |it |can |exacerbate |the |effect |of |head |trauma |
**Head |elevation |and |free |water |restriction |are |appropriate |measure |in |the |measurement |of |head |
trauma, |depend |on |the |type |of |injury.
Clinical |manifestation |of |a |stroke |with |the |right |cerebral |hemisphere. |

Norepinephrine:
Gamma-aminobtyric |acid |(GABA): |reduce |the |conduction |of |singal |transmission |of |CNS |(inhibit)
**Gaba |prevent |electrical |signal |to |go |down
