A nurse is reviewing a cardiac rhythm strip of a client who has atrial flutter.

Which of the following findings should the nurse expect?

Progressively longer PR durations.

Undetectable P waves.

A saw-tooth pattern with an atrial rate of 250 to 400/min.

Absent PR intervals with a ventricular rate of 40 to 60/min.

Answer and Explanation

The Correct Answer is C

A saw-tooth pattern with an atrial rate of 250 to 400/min is a characteristic finding on a cardiac rhythm strip of a client who has atrial flutter.
Choice A is incorrect because progressively longer PR durations are characteristic of a Mobitz type I second-degree AV block, not atrial flutter.
Choice B is incorrect because undetectable P waves are characteristic of atrial fibrillation, not atrial flutter.
Choice D is incorrect because absent PR intervals with a ventricular rate of 40 to 60/min are characteristic of third-degree AV block, not atrial flutter.

Correct Answer is C

Explanation

The nurse’s priority for immediate intervention is tachypnea, which is rapid breathing.
Tachypnea can be a sign of respiratory distress and requires immediate intervention.
Choice A is wrong because while a fever may indicate an infection, it is not the priority for immediate intervention.
Choice B is wrong because while blood-tinged secretions may indicate bleeding, it is not the priority for immediate intervention.
Choice D is wrong because while IV infiltration may cause discomfort and require attention, it is not the priority for immediate intervention.

A. Use an aseptic technique when changing the dressing. B. Cleanse the site with povidone-iodine. C. Flush the catheter using a 10-mL syringe. D. Change the dressing every 24 hours.

Correct Answer is A

Explanation

The aseptic technique is important to prevent infection when changing the dressing of a central venous access device.
Choice B is not correct because povidone-iodine is not always the recommended cleansing agent for central venous access devices.
Choice C is not correct because a 10-mL syringe may generate too much pressure and damage the catheter.
Choice D is not correct because the dressing does not always need to be changed every 24 hours; the frequency of dressing changes depends on the type of dressing and the condition of the site.
