The flashcards below were created by user duboy78 on FreezingBlue Flashcards. What would you like to do?


  1. Afterload

    Stroke Volume
    The amount of resistance to the ejection of blood from the ventricle.

    The amount of blood ejected per heart beat, AVG. 70 ml.

    Increased after load= Decreased stroke volume.
  2. Myocardial Infarction (MI)

    Bowel Regimen
    What happens to the myocardium during infarction?
    Patient is asked to take stool softners, so they dont strain when taking a crap.

    The myocardium is starved for O2 and the tissues dies and damage results.
  3. Troponin
    When do Levels rise?
    • Troponin 1 indicates some amount of cardiac muscle damage with levels above .4 ng/ml.
    • This is an accurate and reliable indicator of an myocardial infarction.
    • Levels increase within hours and can stay elevated for 3 weeks.
  4. ACS (Acute Coronary Syndrome)= Acute Myocardial Infarction

    Atypical Symptoms-
    • Not normal symptoms, can be shown as secondary symptoms.
    • SOB, indigestion, nausea, anxiety, cool/clamy skin, tachycardia, tachypnea, or feeling of doom.
    • Women are not usually diagnosed right off becaue they show these secondary s/s.
  5. Angina Pectoris= Chest Pain=Symptom

    Causes
    Atherosclerosis and increased O2 demand: from exercise stress, cold/vasoconstriction, and heavy meal causing blood to go to guts.
  6. Nitroglycerin= Vasodilator

    Action
    Decreases Myocardial oxygen consumption and are a vasodilator.
  7. Cardiac Rehab

    Phases

    Why is walking part of plan of care?
    • I-Diagnosis of Atherosclerosis
    • II-After discharge, exercise, diet, and eduction. 1-6 months
    • III- Long-term outpatient program.

    Because walking is good for heart health.
  8. Interventions for reducing myocardial oxygen consumption-

    Therpeutic effects for CAD-
    Ca2+ channel blockers= Prevents calcium from entering muscle cells, which prevents muscle contractions, it promotes muscle relaxation.

    Relaxation of smoothe muscle that surrounds the coronary arteries causing them to relax and dilate, which increases blood flow to the heart.

  33. Renin-angiotensin system=

    R/T Hypovolemia and Hypotension
    Renin-Angiotensin system= Vasarecta cells monitor BP for: low blood pressure and low blood volume, which causes the release of renic due to low BP.

    • Renin changes to Angiotensin.
    • Angiotension I converst to Angiotension II, by ace enzyme in the lungs.
    • Angiotension II causes vasoconstriction and alderstrone production with ADH to retain sodium and water to raise fluid levels in the cardio vascular system. Which raises BP.

  36. Difficulty urinating = Dysuria

    Nursing Interventions-
    Interventions- Straight catheter as needed, administer medications as directed, privacy, warm bath, analgesics, and treat infection/ obstruction.
  37. Kidney stones=

    ESWL
    Kidney stones= Nephrolithiasis= Stones in the Kidney.

    ESWL ( Extracorporeal shock wave lithotripsy) Most common treatment for stones.

    Calcium stones are most common stone.
  38. ESRD (End Stage Renal Disease)= Renal Failure

    (Patient teaching)
