1. A nurse is describing the process by which blood is ejected into circulation as the chambers of the
heart become smaller. The instructor categorizes
... [Show More] this action of the heart as what?
- Systole
2. During a shift assessment, the nurse is identifying the clients point of maximum impulse (PMI). Where
will the nurse best palpate the PMI?
- Left midclavicular line of the chest at the fifth intercostal space
3. The nurse is calculating a cardiac patients pule pressure. If the patients blood pressure is 122/76 mm
Hg, what is the patients pulse pressure?
- 46 mm Hg
4. The nurse is caring for a patient admitted with unstable angina. The laboratory result for the initial
troponin I is elevated in this patient. The nurse should recognize what implications of this assessment
finding?
- This is an accurate indicator of myocardial injury
5. The nurse is conducting patient teaching about cholesterol levels. When discussing the patients
elevated LDL and lowered HDL levels, the patient shows an understanding of the significance of these
levels by stating what?
- Increased LDL and decreased HDL increase my risk of coronary artery disease
6. The physician has placed a central venous pressure (CVP) monitoring line in an acutely ill patient so
right ventricular function and venous blood return can be closely monitored. The results show decreased
CVP. What does this indicate?
- Possible hypovolemia
7. While auscultating a patient’s heart sounds, the nurse hears an extra heart sound immediately after
the second heart sound (S2). An audible S3 would be considered an expected finding in what patient?
- A 20-year-old patient
8. The physical therapist notifies the nurse that a patient with coronary artery disease (CAD) experiences
a much greater than average increase in heart rate during physical therapy. The nurse recognizes that an
increase in heart rate in a patient with CAD may result in what?
- Myocardial ischemia
9. The nurse is caring for a patient who has a history of heart disease. What factor should the nurse
identify as possible contributing to a decrease in cardiac output?
- A heart rate of 54 bpm
10. The nurse is caring for an 82-year-old patient. The nurse knows that changes in cardiac structure and
function occur in older adults. What is a normal change expected in the aging heart of an older adult?

lOMoARcPSD|25111999
- Widening of the aorta
11. A resident of a long-term care facility has complained to the nurse of chest pain. What aspect of the
resident’s pain would be most suggestive of angina as the cause?
- The pain occurs immediately following physical exertion
12. The critical care nurse is caring for a patient with a central venous pressure (CVP) monitoring system.
The nurse notes that the patients CVP is increasing. Of what may this indicate?
- Hypervolemia
13. The critical care nurse is caring for a patient with a pulmonary artery pressure monitoring system.
The nurse is aware that pulmonary artery pressure monitoring is used to assess left ventricular function.
What is an additional function of pulmonary artery pressure monitoring systems?
- To assess the patient’s response to fluid and drug administration
14. The cardiac care nurse is reviewing the conduction system of the heart. The nurse is aware that
electrical conduction of the heart usually originates in the SA node and then proceeds in what
sequence?
- SA node to Av node to bundle of His to Purkinje fibers
15. A patient has had a myocardial infarction and has been diagnosed as having damage to the layer of
the heart responsible for the pumping action. You are aware that the damage occurred where?
- Myocardium [Show Less]
