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

Metformin should be withheld for a minimum of 48 hours after the procedure.

This is because metformin can increase the risk of contrast-induced acute kidney injury (CI-AKI) when undergoing contrast imaging.
Choice A, Clopidogrel, is not an answer because it is not mentioned in the search results as a medication that needs to be withheld after a CT scan with contrast media.
Choice B, Furosemide, is not an answer because it is not mentioned in the search results as a medication that needs to be withheld after a CT scan with contrast media.
Choice D, Carvedilol, is not an answer because it is not mentioned in the search results as a medication that needs to be withheld after a CT scan with contrast media.

A. Place pillows under the client's knee. B. Perform range-of-motion exercises on the client's knee. C. Apply an ice pack to the client's knee. D. Gently massage the area around the client's incision.

Correct Answer is C

Explanation

Applying an ice pack can help reduce pain and swelling after total knee arthroplasty.
Placing pillows under the client’s knee (choice A) is not recommended as it can hinder circulation and delay healing.
Performing range-of-motion exercises to the client’s knee (choice B) may be part of the rehabilitation process but should be done under the guidance of a physical therapist and may not be appropriate for immediate pain relief.
Gently massaging the area around the client’s incision (choice D) may not be appropriate as it can cause discomfort and disrupt the healing process.
