  1. 1A 34-year-old man who is an intravenous drug user has presented to the emergency department with malaise, abdominal pain, and lethargy. The health care team wants to rule out endocarditis as a diagnosis. Staff of the department would most realistically anticipate which of the following sets of diagnostics?
    1. ACT of the heart, chest x-ray, and ECG
    2. BECG, blood pressure, and stress test
    3. CCardiac catheterization, chest x-ray, electrolyte measurement, and white cell count
    4. DEchocardiogram, blood cultures, and temperature
  2. 2A client has been diagnosed with mitral valve stenosis following his recovery from rheumatic fever. Which of the following teaching points would be most accurate to convey to the client?
    1. AYour mitral valve isn't opening up enough for blood to flow into the part of your heart that sends blood into circulation
    2. BThe valve between your left ventricle and left atria is infected and isn't allowing enough blood through.
    3. CYour heart's mitral valve isn't closing properly so blood is flowing backward in your heart and eventually into your lungs.
    4. DThe normal tissue that makes up the valve between the right sides of your heart has stiffened
  3. 3On a routine physical exam visit, the physician mentions that he hears a new murmur. The patient gets worried and asks, What does this mean? The physician responds,
    1. AIt would be caused by stress. Let's keep our eye on it and see if it goes away with your next visit.
    2. BThis may make you a little more fatigued than usual. Let me know if you start getting dizzy or light-headed.
    3. CThis could be caused by an infection. Have you been feeling well the past few weeks?
    4. DOne of your heart valves is not opening properly. We need to do an echocardiogram to see which valve is having problem.
  4. 4A 13-year-old boy has had a sore throat for at least a week and has been vomiting for 2 days. His glands are swollen, and he moves stiffly because his joints hurt. Throat cultures show infection with group A streptococci. This child is at high risk for
    1. Ainfective endocarditis
    2. Bvasculitis
    3. Cmyocarditis
    4. Dmitral valve stenosis.
  5. 5A physician has ordered the measurement of a cardiac patient's electrolyte levels as part of the client's morning blood work. Which of the following statements best captures the importance of potassium in the normal electrical function of the patient's heart?
    1. AThe reciprocal movement of one potassium ion for one sodium ion across the cell membrane results in the production of an action potential.
    2. BThe impermeability of cardiac cell membranes to potassium allows for action potentials achieved by the flow of sodium ions.
    3. CPotassium is central to establishing and maintaining the resting membrane potential of cardiac muscle cells.
    4. DPotassium catalyzes the metabolism of ATP, producing the gradient that results in electrical stimulation.
  6. 6A 63-year-old male client has been diagnosed with a bundle branch block. How will this client's care team most likely expect his condition to be expressed diagnostically?
    1. AHis ECG will show a flattened P wave as a result of impaired atrial depolarization.
    2. BConduction from the Purkinje fibers to the bundle branches is compromised by inadequate conduction
    3. CHis ECG will show an inordinately wide QRS complex because impulses are bypassing the normal conduction tissue.
    4. DHis AV node will be performing the primary pacemaker role due to inadequacy of the SA node.
  7. 7A client has been diagnosed with mitral valve stenosis following his recovery from rheumatic fever. Which of the following teaching points would be most accurate to convey to the client?

    1. AThe valve between your left ventricle and left atria is infected and isn't allowing enough blood through.
    2. BYour heart's mitral valve isn't closing properly so blood is flowing backward in your heart and eventually into your lungs.
    3. CYour mitral valve isn't opening up enough for blood to flow into the part of your heart that sends blood into circulation.
    4. DThe normal tissue that makes up the valve between the right sides of your heart has stiffened.
  8. 8You are looking after a 61-year-old male client in the hospital who has presented with a new onset of atrial fibrillation. Which of the following courses of treatment would you most likely expect the attending physician to initiate?
    1. AAntihypertensives and constant cardiac monitoring in a high acuity unit
    2. BImmediate cardioversion followed by surgery to correct the atrial defect
    3. CAnticoagulants and beta-blockers to control rate
    4. DDiuretics, total bed rest, and cardioversion if necessary
  9. 9The initial medical management for a symptomatic patient with obstructive hypertrophic cardiomyopathy (HCM) would be administering a medication to block the effects of catecholamines. The nurse will anticipate administering which of the following medications?
    1. ALisinopril, an ACE inhibitor
    2. BLasix, a diuretic
    3. CLanoxin, an inotropic
    4. DPropranolol, a beta-adrenergic blocker
  10. 10The amount of blood pumped by one ventricle in one minute, is called the
    1. Aejection fraction.
    2. Bstroke volume.
    3. Ccardiac output.
    4. Dend-diastolic volume.
