|
Term
in what order is MONA given |
|
Definition
ONMA oxygen before morphine because when you come in with chest pain, it is supply and demand, readily available, nitrates next you want to see what happens following nitrate admin. morphine may change action of heart so given next, vasodilation reduces preload, helps with anxiety aspirin is given last because it helps to prevent problems in the future. |
