  1. The objective evaluation of the ______ ______ includes the RBCs, hematocrit, hemoglobin, and the WBCs.
    hematological system
  2. The four types of WBC granulocytes are:
    Neutrophils, Eosinophils, basophils, lymphocytes
  3. The heart works as two pumps with the right side of the heart pumping blood to the ______, and the left side pumping blood to the ______ ______.
    Lungs; systemic circulation
  4. True or False: Blood pressure is measured indirectly.
    True
  5. True or False: The systemic circulation supplies blood to the organs and tissues of the body.
    True
  6. The heart is supplied with blood via the right and left ______ ______ that originate at the base of the aorta.
    Coronary arteries
  7. The ______ ______ reflects the contraction and relaxation of the heart.
    Cardiac cycle
  8. ______ ______ is an index that estimates contractile function of the left ventricle.
    Ejection fraction (expected EF is 60-70%)
  9. What two histories are assessed to determine previous heart conditions and risk factors for heart disease?
    Medical and family
  10. Heart sounds are assessed by which of five positions:
    Aortic, pulmonic, Erb’s point, tricuspid, and mitral
  11. True or false: Cardiac catheterization and coronary angiography is non-invasive.
    False: It is invasive. A catheter is placed in the vascular system and threaded to the heart, where dye is injected to assess chamber function and visualize the coronary arteries.
  12. True or False: Nursing management for cardiac system diagnostic tests relies on patient education.
    True
  13. Which of the following blood products or proteins are used in blood clotting? Choose all that apply.
    a. Platelets
    b. Fibrinogen
    c. Basophils
    d. heparin
    A and B – these two are used in hemostasis
  14. Which of the following areas are best used to assess pallor due to anemia?
    a. Mucous membranes and conjunctivae
    b. Inner aspects of the forearm, fingernails, and lips
    c. Nasolabial fold, palpebral conjunctiva, and lips
    d. Lips, behind the ears, and fingernails
    A
  15. In general, which of the following causes normal heart sounds?
    a. Blood filling the left ventricle
    b. Blood entering the left atrium
    c. Closing of the heart valves
    d. Opening of the heart valves
    C
  16. What is the phase of the cardiac cycle during which the ventricles relax and the decreased intraventricular pressure causes the mitral valve to open?
    a. Systole
    b. P wave
    c. Diastole
    d. T wave
    • C
    • diastole is correlated with ventricular filling
  17. What is the extra heart sound, normal in some clients, that occurs early in diastole during a period of rapid ventricular filling and which in the older adult signifies heart failure?
    a. S1
    b. S2
    c. S3
    d. S4
    D
  18. Which normal heart sound is produced when the pressure in the ventricle drops below aortic pressure and the aortic valve closes?
    a. S1
    b. S2
    c. S3
    d. S4
    B
  19. Which heart sound is produced when the ventricle contracts, and the ventricular pressure rapidly exceeds left atrial pressure, causing the mitral valve to close?
    a. S1
    b. S2
    c. S3
    d. S4
    A
  20. A physiologically split S2 sound is best auscultated over which area?
    a. The cardiac apex near the fifth and sixth ICS
    b. The area of apical impulse near the fifth ICS
    c. The cardiac apex near the second ICS
    d. The left second ICS close to the sternum
    D
  21. Which of the following is the appropriate auscultation site for the mitral valve area in the client?
    a. Second ICS to the left of the midsternal line
    b. Fourth ICS, 2 to 3 cm to the right of the midsternal line
    c. Fifth ICS, approximately at the left midclavicular line
    d. Third ICS at the left midsternal border
    • C
    • the mitral area and the apical pulse are the fifth ICS midclavicular line
  22. What is the scale used to assess heart murmurs?
    a. I to IV
    b. I to VI
    c. A to E
    d. I to III
    B
