assess cardiac, renal, hemodynamic status and monitor BP and ECG closely

18
Q

what class is morphine sulfate

A

opiod analgesic

19
Q

what is the mode of action for morphine sulfate;

A

pain relief, drowsy, mental clouding, reduce anxiety, sense of well being

20
Q

what is important teaching of morphine sulfate

A 
dont admin if RR are low
use caution with head injury pt
don't use with other CNS depressants
*monitor opiod OD
coma, resp depression, pinpoint pupils
21
Q

what does morphine sulfate do for a STEMI

A

(IV) aids ventilation which reduces cardiac preload, modest atrial dilation leading to slight decrease in after load which leads to decrease cardiac O2 demand
