Cardiovascular Exam Questions Questions
Question 1 of 5

Correct Answer: B
Rationale: Auricles are specific structures that extend from the atria but are not synonymous with them.
Question 2 of 5
The period between the filling of the ventricles and the opening of the semilunar valves is called:

Question 3 of 5
A patient has recently started on digoxin (Lanoxin) in addition to furosemide (Lasix) and captopril for the management of heart failure. Which assessment finding by the home health nurse is a priority to communicate to the health care provider?
Correct Answer: C
Rationale: Hypokalemia can predispose the patient to life-threatening dysrhythmias (e.g., premature ventricular contractions) and potentiate the actions of digoxin. Hypokalemia also increases the risk for digoxin toxicity, which can also cause life-threatening dysrhythmias. The other data indicate that the patient's heart failure requires more effective therapies, but they do not require nursing action as rapidly as the low serum potassium level.
