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.

A pneumothorax is a collapsed lung that occurs when air leaks into the space between the lung and the chest wall.
This can cause diminished breath sounds on the affected side. Distended neck veins are not a symptom of pneumothorax.
B) Itching over the incision is not a symptom of pneumothorax.
C) Irregular heart rate is not a symptom of pneumothorax.
Correct Answer is A
Explanation
This can help prevent dizziness and loss of balance, which are common symptoms of Ménière’s disease.
Choice B is not correct because range-of-motion exercises to the client’s neck every 4 hours are not a standard intervention for Ménière’s disease.
Choice C is not correct because aspirin is not always the recommended medication for headaches associated with Ménière’s disease.
