Extract:
Question 1 of 5
A nurse is assessing a patient with known mitral valve regurgitation. The nurse should expect to hear which of the following heart sounds?
Correct Answer: A
Rationale: Mitral regurgitation causes a holosystolic murmur due to backflow into the left atrium.
Question 2 of 5
A nurse is caring for a client diagnosed with heart failure and atrial fibrillation. The client reports feeling palpitations and shortness of breath. The nurse is aware that clients with atrial fibrillation are at risk for which complication?
Correct Answer: C
Rationale: Atrial fibrillation increases the risk of embolic stroke due to blood pooling in the atria, leading to clot formation that can travel to the brain.
Question 3 of 5
A nurse is caring for a client who reports shortness of breath and heart palpitations. An ECG confirms the client is experiencing ventricular tachycardia (VT). The nurse palpates a rapid carotid pulse with a blood pressure of 70/30, and the client reports feeling dizzy. The nurse should anticipate the need for which priority action?
Correct Answer: D
Rationale: Synchronized cardioversion is used for unstable VT with a pulse to prevent inducing ventricular fibrillation.
