Question 1 of 5
A patient on the telemetry unit develops atrial flutter with a heart rate of 150, respirations 26, b/p 118/64 and a O2 saturation of 90% while sitting down. Which action should the nurse do FIRST?
Correct Answer: D
Rationale: With an O2 saturation of 90%, the priority is to address hypoxia by administering supplemental oxygen first to improve oxygenation.
Question 2 of 5
A client is experiencing atrial fibrillation for 2 weeks and did not respond to medication therapy. The client is scheduled for an elective (outpatient) cardioversion. Which other procedure or test does the nurse anticipate this client will need?
Correct Answer: B
Rationale: A transesophageal echocardiogram is needed before cardioversion in prolonged atrial fibrillation to rule out atrial thrombi, which could embolize during the procedure.
Question 3 of 5
A nurse is reviewing medications prescribed for a client. For which of the following prescriptions should the nurse contact the provider for clarification?
Correct Answer: C
Rationale: Regular insulin dosing requires clarification on timing and frequency (e.g., how many meals), as vague orders can lead to administration errors.
