Extract:
Question 1 of 5
A nurse is interpreting a client's ECG strip. Which of the following components of the ECG should the nurse examine to determine the time it takes for ventricular depolarization and repolarization?
Correct Answer: B
Rationale: The QT interval measures the total time taken for both ventricular depolarization and repolarization.
Question 2 of 5
A nurse is admitting a client who has acute heart failure following a myocardial infarction (MI). The nurse recognizes that which of the following prescriptions by the provider requires clarification?
Correct Answer: A
Rationale: Administering 0.9% normal saline IV at 50 mL/hr continuously in acute heart failure can exacerbate fluid overload, worsening symptoms like pulmonary edema.
Question 3 of 5
A nurse in a cardiac care unit is caring for a client with acute right-sided heart failure. Which of the following findings should the nurse expect?
Correct Answer: C
Rationale: Ascending dependent edema results from increased venous pressure and fluid retention in the lower extremities, common in right-sided heart failure due to impaired venous return and fluid overload.
Question 4 of 5
A nurse is providing teaching for a client who has a new diagnosis of angina pectoris. Which of the following information should the nurse include about anginal pain?
Correct Answer: B
Rationale: Exertion increases myocardial oxygen demand, while anxiety triggers a sympathetic response, both of which can precipitate anginal pain due to the heart's inability to meet increased oxygen requirements.
Question 5 of 5
Examine the attached ECG image and identify the type of arrhythmia present. The ECG shows a series of wide QRS complexes occurring at a rapid rate.
Correct Answer: B
Rationale: Ventricular tachycardia is characterized by a rapid rate and wide QRS complexes. This rhythm originates in the ventricles and can lead to a decrease in cardiac output and possible deterioration into ventricular fibrillation.
