Chapter 25 : Assessment of Cardiovascular Function Questions
Question 1 of 5
The nurse is calculating a cardiac patients pulse pressure. If the patients blood pressure is 122/76 mm Hg, what is the patients pulse pressure?
Correct Answer: A
Rationale: Pulse pressure is the difference between the systolic and diastolic pressure. In this case, this value is 46 mm Hg (122 - 76 = 46).
Question 2 of 5
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 implication of this assessment finding?
Correct Answer: C
Rationale: Troponin I, which is specific to cardiac muscle, is elevated within hours after myocardial injury. Even with a diagnosis of unstable angina, this is an accurate indicator of myocardial injury.
Question 3 of 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?
Correct Answer: A
Rationale: Elevated LDL levels and decreased HDL levels are associated with a greater incidence of coronary artery disease.
Question 4 of 5
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?
Correct Answer: A
Rationale: Hypovolemia may cause a decreased CVP. MI, valve regurgitation, and heart failure are less likely causes of decreased CVP.
Question 5 of 5
While auscultating a patients 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?
Correct Answer: B
Rationale: S3 represents a normal finding in children and adults up to 35 or 40 years of age. In these cases, it is called a physiologic S3. It is an abnormal finding in a patient with an artificial valve, an older adult, or a patient who takes a beta blocker.
