A nurse is monitoring a client's heart rhythm following the insertion of a permanent pacemaker.
Which of the following images should the nurse expect?
A regular sinus rhythm.
A chaotic, irregular rhythm.
Absence of any electrical activity.
A series of spikes followed by a QRS complex.
The Correct Answer is D
A pacemaker sends electrical signals to the heart to regulate the heartbeat.
On an electrocardiogram (ECG), these signals appear as small spikes followed by a QRS complex, which represents the contraction of the ventricles.
Choice A, A regular sinus rhythm, is not the correct answer because a regular sinus rhythm is a normal heart rhythm that originates from the sinoatrial (SA) node and does not involve a pacemaker.
Choice B, A chaotic, irregular rhythm, is not the correct answer because a pacemaker is designed to regulate the heartbeat and prevent chaotic or irregular rhythms.
Choice C, the Absence of any electrical activity, is not the correct answer because a pacemaker sends electrical signals to the heart to regulate its activity.

Correct Answer is C
Explanation
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 nurse should instruct the client to obtain sterile lancets for blood glucose monitoring.
Lancets are small needles used to prick the skin to obtain a blood sample for testing blood glucose levels.
Choice B is wrong because compression stockings are not necessary for blood glucose monitoring.
Choice C is wrong because toenail clippers are not necessary for blood glucose monitoring.
Choice D is wrong because a hand mirror is not necessary for blood glucose monitoring.
