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
The nurse should plan to notify the Rapid Response Team first.
The client’s blood pressure is elevated, heart rate is high, respiratory rate is high, and oxygen saturation is low.
These are all signs of potential instability and the Rapid Response Team should be notified immediately.
Choice A is incorrect because while obtaining an ECG may be important, it is not the nurse’s first priority in this situation.
Choice B is incorrect because while calculating the extent of burns using the rule of nines may be important, it is not the nurse’s first priority in this situation.
Choice D is incorrect because while initiating peripheral IV access may be important, it is not the nurse’s first priority in this situation.
