Q

nitrates/nitroglycerin action

A

reduce myocardial oxy demand, so ischemia and pain decreased, dilate veins and arteries, relax alveoli so increase oxy

30
Q

serum cardiac markers appear

A

released in circulation after stress like myocardial infarction or ischemia/decreased oxy to heart

31
Q

serum cardiac markers purpose

A

diagnose size and severity of MI

32
Q

serum cardiac markers: 2 types

A

CK - Creatinine Kinase: CK-MB specific to heart tissue

Troponin

33
Q

CK - Creatinine Kinase

A

enzyme in heart, skeletal system and brain, high level indicate damage or MI. CK-MB specific to myocardium

34
Q

troponin

A

a protein in blood of heart muscle. damaged cells release troponin. needed for contractions,

35
Q

coronary artery disease lipid profile

A

total cholesterol <200
triglycerides <150
cholesterol: LDL <100 HDL >60

36
Q

coronary artery perfusion imaging

A

spect or pet; radioactive isotopes injected intravenously; patient urine radioactive for 24 hours post testing

37
Q

cardiac catherization CAD

A

evaluate patency of coronary arteries, catheter insert into radial/femoral artery, NPO

38
Q

PTCA post procedure complications

A

bleeding, cardiac, perfusion, acute kidney injury

39
Q

maintenance nitrates

A

extended release capsule and transdermal daily use for angina prevention

40
Q

2 type transdermal nitrates

A

paste/ointment and patch

41
Q

acute use nitrates

A

sublingual: powder and tablet under tongue at onset of angina

42
Q

transdermal nitrates nursing care

A

wear gloves

43
Q

nitrates goal

A

vasodilation of blood vessels/coronary arteries

44
Q

PQRST

A

pain measurement; Provokes, Quality, Radiates, Severity and Timing

45
Q

beta blockers effect

A

reduce HR, BP and force of contractions so decrease the amt of oxy needed to pump blood

46
Q

calcium channel blockers effect

A

dilate arteries, decrease force of heart contractions so lower BP

47
Q

vein dilation effect

A

dilated veins reduce amt of blood flow back to heart so reduce heart workload

48
Q

artherosclerosis is

A

fatty streaks, cholesterol, calcium and fibrin (a clotting material)

49
Q

PQRST P is what?

A

provokes; what causes pain? what makes it better or worse?

Q

PQRST Q is what?

A

quality: describe it? what does it feel it? sharp, stabbing, dull, burning

Q

PQRST S is what?

A

severity: rate on scale of 1-10

53
Q

PQRST T is what?

A

timing? when does pain occur? how long does it last?

54
Q

troponin stays elevated how long?

A

up to 3 weeks
