Chapter 25 : Assessment of Cardiovascular Function Questions
Question 1 of 5
A nurse is describing the process by which blood is ejected into circulation as the chambers of the heart become smaller. The instructor categorizes this action of the heart as what?
Correct Answer: A
Rationale: Systole is the action of the chambers of the heart becoming smaller and ejecting blood. This action of the heart is not diastole (relaxations), ejection fraction (the amount of blood expelled), or repolarization (electrical charging).
Question 2 of 5
During a shift assessment, the nurse is identifying the clients point of maximum impulse (PMI). Where will the nurse best palpate the PMI?
Correct Answer: B
Rationale: The left ventricle is responsible for the apical beat or the point of maximum impulse, which is normally palpated in the left midclavicular line of the chest wall at the fifth intercostal space.
Question 3 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 4 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 5 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.
