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.
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 A
Explanation
“The client’s capillary refill in the left toe is 6 seconds.” Capillary refill time is the time it takes for blood to return to the capillaries after pressure has been applied to the skin.
A normal capillary refill time is less than 2 seconds.
A capillary refill time of 6 seconds indicates poor blood flow to the left toe and requires immediate intervention by the nurse.
Choice B is not the correct answer because while a pain level of 7 on a scale from 0 to 10 at the operative site is concerning, it does not require immediate intervention by the nurse.
Choice C is not the correct answer because an oral temperature of 38.3° C (100.9° F) is only slightly elevated and does not require immediate intervention by the nurse.
Choice D is not the correct answer because while 100 mL of blood in a closed-suction drain may be concerning, it does not necessarily require immediate intervention by the nurse.

Explanation
A pericardial friction rub is highly specific for acute pericarditis and is generally heard over the left sternal border.
It is often louder at inspiration but sometimes can be better heard on forced expiration while the patient bends forward.
Choice A is not the answer because it does not correspond to the left sternal border.
Choice B is not the answer because it does not correspond to the left sternal border.
Choice D is not the answer because it does not correspond to the left sternal border.
