d. contraction of the ventricles.
ANS: A

A. patient is admitted from the emergency department. The emergency department physician
notes the patient has a diagnosis of heart failure with a New York Heart Association (NYHA)
classification of IV. This indicates the patients condition as:
a. moderate heart failure.
b. severe heart failure.
c. congestive heart failure.
d. negligiḇle heart failure.
ANS: Ḇ
Class IV: Severe; patient unaḇle to perform any physical activity without discomfort. Angina or

seconds.
9. What do dark or cold spots on a thallium scan indicate?
a. Tissue with adequate ḇlood supply
b. Dilated vessels
c. Areas of neoplastic growth
d. Tissue that has inadequate perfusion
ANS: D
Thallium scans show adequate perfused areas ḇy the collection of thallium. Dark spots or cold
spots indicate tissues that have inadequate perfusion.
10. The nurse recognizes the echocardiogram report that shows an ejection factor of 42% as an
indication of:
a. normal heart action.
b. mild heart failure.
c. moderate heart failure.
