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 B
Explanation
The nurse should consult the client before approaching the dog.
Service dogs are working animals and it is important to respect their role and the handler’s wishes.
Choice A is wrong because petting the dog briefly to demonstrate acceptance could distract the dog from its duties.
Choice C is wrong because offering the dog a bowl of water without consulting the client first could interfere with the dog’s training or schedule.
Choice D is wrong because commanding the dog to sit while talking with the client could confuse the dog and disrupt its training.
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.
