Front 14

myoglobin normal level

Back 14

<90

Front 15

thallium scans

Back 15

show ischemia & necrosis as cold spots (radioisotopes cannot reach these areas)

Front 16

ptca

Back 16

percutaneous tranluminal coronary angioplasty

Front 17

ptca complications (3)

Back 17

bleeding, acute vessel closure, dysrhthmias

Front 18

angina precipitated by

Back 18

exertion or stress

Front 19

when MI's are likely to occur

Back 19

no cause, often in morning after rest

Front 20

angina relieved by

Back 20

nitro, rest

Front 21

mi relieved by

Back 21

opioids

Front 22

MI ischmia duration

Back 23

>30 minutes

Front 24

associated sx with MI (4)

Back 24

nausea, epigastric distress, dyspnea, diaphoresis

Front 25

significance of 30ml/hr urine output

Back 25

sufficient renal perfusion

Front 26

oxygen given for MI

Back 26

4 - 6L

Front 27

vasodilators effects

Back 27

reduce preload and afterload -> decreases o2 demand

Front 28

analgesic of choice given for MI

Back 28

morphine

Front 29

beta-blockers fx on heart (3)

Back 29

1) antidysrhythmic 2) antihypertensive 3) reduce afterload

Front 30

thrombolytic post MI window

Back 30

6 hrs.

Front 31

pt education re chest pain (3)

Back 31

1) stop activity/rest 2) nitro SL - 5 min - nitro - 5 min - nitro - 5 min 3) call 911

Front 32

what is cardiogenic shock

Back 32

usu after MI, sustained hypotension and hypoperfusion

Front 33

how do you distinguish angina from MI

Back 33

if it's not relieved by rest and nitro, assume it's MI

Front 34

ST segment elevation indicates

Back 34

ischemia

Front 35

positive inotropic agent does what?

Back 35

increases force and strength of contraction

Front 36

positive chronotropic drug does what?

Back 36

increases cardiac rate

Front 37

iso-osmolar fluid volume deficit is r/t and why

Back 37

hemorrhage (fluids and solutes are lost in proportionally

Front 38

s/sx prostate cancer (hint - think enlarged prostate gland)

Back 38

urine problems r/t impingement on urethra leading to UTI

Front 39

important factor re d/c'ing tpn

Back 39

gradual tapering so that hypoglycemia doesn't occur

Front 40

why are cushingoids at risk for infection

Back 40

cortisol excess decreases immunity

Front 41

DKA occurs in which type of DM?

Back 41

1 IDDM under stress

Front 42

deep and rapid respirations are called

Back 42

kussmaul's

Front 43

peak time of NPH insulin and intervention

Back 43

6 - 12 hours. insulin pushes glucose and potassium into cells, lowering BG. so a snack is needed to prevent hypoglycemia

Front 44

characteristic symptoms of non-hemolytic transfusion reaction

Back 44

sudden onset of chills and fever, headache, flushing, anxiety. body is rejecting donor's blood

Front 45

chronic renal failure diet goal

Back 45

protein restriction

Front 46

acute respiratory failure criteria

Back 46

acidosis, PO2 <50 PCO2>50

Front 47

calcium channel blockers have what affect on coronary BV's?

Back 47

dilation so used for angina

Front 48

key sign for fluid volume deficit

Back 48

postural hypotension
