10. Dignostic findins
Use Nitro at home and if nitro doesn’t work go to hosp to adm strptokinase within 6 hrs of MI
In a MI very severe crushing severe chest pain, bld is divt away from skin, cold sweat, grey in color, as bld is shunted away from periphery, Jaw, down left arm and to the back
If nitro q5min x3 doses relieves pain it is prob angina
If pain not relieved then it is probl a MI

Client at hight risk, put on low dose hep 5000 u bid sq, or lovenox, due to allegeric rxn to hep, given based on wt. Give inch around umbilicus. DO NoT asp or masg area.
If clint asks about dose, tell the they hav a chng in act level, ie bedrest, to prvt clots. At home they would be on coumadin

14. manga
We can give Nitro, sling, or run a nitro drip is chst pain unrelved with nirto sling, as paste is used for mang or acute episds of chest pain, so it is very rapid on set revesr myo car ishch.
If chest pain cont give mcg per minute of nitro. Usually 10mcg per minute for chest pain to titrate drip.
Give MS for cardiac client/drug of choice/has advngts, dec anxiety,CNS deprst, slow hypervetn and RR, relv Cest pain, and good give q15min 2-3mg IVP and repeat for pain releif. And dec preload and afterload(dec myo O2 demand ,Hrt doesn’t have to pump as hard) which is why they get low BP so monitor BP.
Nitrates also dec prelod and aft load

15. Beta Blck Always give as protocal: Lopressor
Beta Bcks and Nitrates to dec injury, pt are prophylatically placed on both. To save myocardl tissue.
So when the client comes in put them on telemrty/o2/meds
If its anginal pain alone, nitrats will work if not give IV drip

If client doesn’t chang lifestyle they come back, so there has sto be a lot of lifestyle changes, Nurse must use motivational teaching,
Pat should be follwd up by cariologys and go to rehap,
Client can go back to sexual act with 1 wk after uncomplicated MI
Healing time is from 4-6 weeks, stages, ischmeia, injurgy, then necrosis
Alt,ASt,LDH, in system for 6-8 days, if a pat has had chest pain for 1 week they can remain high, if EKG is showing damage use old enzymes.
