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 A
Explanation
Place two-bed pillows between the legs when in bed.
To prevent hip dislocation after total hip arthroplasty, the nurse should place two-bed pillows between the client’s legs when in bed.
This helps maintain proper alignment and prevent the hip from dislocating.
Choice B is incorrect because leaning forward when attempting to stand can increase the risk of hip dislocation.
Choice C is incorrect because removing the wedge device when turning can increase the risk of hip dislocation.
Choice D is incorrect because elevating the knees higher than the hips when sitting can increase the risk of hip dislocation.
