Show Answers:

  1. Decrease blood volume can lead to an elevated 1.can result from 2
    • hematocrit value
    • vascular volume depletion.
  2. Decreases in hematocrit and hemoglobin values can indicate
  3. Low potassium (Hypokalemia) causes increased
    abnormal heart electrical impulses
  4. Hypokalemia can be detected through-----reading that show flattening and inversion of the----
    • electrocardiogram
    • T wave
  5. Phosphorus levels should be interpreted with
    calcium levels
  6. Blood urea nitrogen (BUN): and creatinine level is used to
    detect the effect of heart disease on the kidney.
  7. The BUN level is elevated in
    heart disorders that adversely affect renal circulation
  8. Sedimentation rate (ESR): Nonspecific test indicating
    inflammatory response somewhere in the body.
  9. Clients with low HDL and high LDL levels are at high risk for
    coronary artery disease and myocardial infarction.
  10. -----is required for synthesis of prothrombin
    Vitamin K
  11. Partial Thromboplastin Time (PTT)- Normal:
    60-70 seconds
  12. The level of prothrombin can be used to monitor the response of patient on anticoagulant therapy specifically
    warfarin (Coumadin)therapy.
  13. Partial Thromboplastin Time (PTT)- Normal: 60-70 seconds Can be used to detect deficiencies in all clotting factors except VII and XIII hence can be used to monitor
    heparin dosage
  14. Coagulation Time (Lee White Clotting Time)-
    Normal:----------Can also be used to monitor-----
    • 5-15 minutes.
    • heparin therapy.
  15. enzymes are released from the damage cells and they include-
    CPK, LDH, AST (SGOT); and Troponin
  16. Serum lipids Before the test client must be

  19. CKP-BB is from the
  20. CKP-MB is the specific lab test Normal value
    Male: 55-170 U/ml ; Female: 30-135 U/L
  21. When the LDH I becomes higher than the LDH II, an----has occurred and is diagnostic of an----
    • enzyme flip"
    • MI.
  22. LDH Normal value in conventional units is
    140 to 280 international units/L.
  23. a myocardial muscle protein released into circulation
    after heart injury.
    Troponin I and Troponin T
  24. Troponin I and Troponin T Normal level is
    < 1.0ng/mL.
  25. An oxygen-binding protein found in cardiac and skeletal muscle.
  26. Remove jewelry or any metal object on the way of
  27. diagnostic test that evaluates the heart's function by record­ing electrical activity.
    Electrocardiography (ECG)
  28. Evaluates efficiency of the heart during exercise such as bike riding or treadmill walking.
    Exercise EKG (stress test
  29. During stress EKG Coffee, cigarettes , caffeine, alcohol and theophylline products are held for---before the test and calcium channel blockers and beta blockers may be held for---
    • 12 hours
    • 24 hours per physician's order
  30. Post-procedure care for stress EKG If performed on an
    outpatient basis, the client should
    not leave the premises until the physician has interpreted the results.
  31. Post-procedure care for stress EKG Instruct the client
    to avoid
    avoid taking a hot bath or shower for at least 1 to 2 hours.
  32. It is a portable equipment which the client can carry around. It is used to monitor dysrhythmias
    Holter monitoring
  33. The client will wear the Holter monitoring for the prescribed length of time and should not get the recorder----or----
    wet or have x-rays
  34. A non-invasive ultrasound of the heart used to examine the heart and provides information about the position, size, and movements of the valves and chambers.
  35. it is a dye can help outline blood flow in the heart.
    Thallium Imaging
