Question 1 of 5
A nurse is reviewing the laboratory values for a client who has heart failure and is taking bumetanide for diuresis. For which of the following results should the nurse notify the provider?
Correct Answer: A
Rationale: Potassium 2.3 mEq/L indicates severe hypokalemia, which can cause dangerous arrhythmias, especially in heart failure.
Question 2 of 5
A nurse is reinforcing teaching with a newly licensed nurse about reading a client's ECG tracing. The nurse should include in the teaching that which of the following ECG components represent the time it takes for ventricular depolarization?
Correct Answer: C
Rationale: The QRS complex represents ventricular depolarization, the electrical activity causing ventricular contraction.
Question 3 of 5
A nurse is caring for a client who recently had surgery for insertion of a permanent pacemaker. Which of the following prescriptions should the nurse question due potential risk/harm to patient?
Correct Answer: C
Rationale: MRI is contraindicated for most pacemakers due to potential interference with function.

Question 5 of 5
A nurse is reinforcing teaching with a newly licensed nurse about reading a client's ECG tracing. The nurse should include in the teaching that the P wave represents which of the following cardiac electrical activities?
Correct Answer: D
Rationale: The P wave represents atrial depolarization, which is the electrical activity that triggers the contraction of the atria.
