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 correct answer is choice B: Insert an NG tube.
Choice A rationale: Inserting an indwelling urinary catheter may be necessary for monitoring urine output in some cases, but in this situation, the priority is to insert an NG tube. This will help prevent aspiration during surgery due to the client's high blood alcohol level, which increases the risk of vomiting.
Choice B rationale: Inserting an NG tube is the priority action for the nurse because a high blood alcohol level increases the risk of vomiting and aspiration during surgery. An NG tube can help reduce this risk by keeping the stomach empty and minimizing the chance of aspiration.
Choice C rationale: Obtaining consent for surgery is important, but in emergency situations, consent may be implied, or a designated surrogate decision-maker may provide consent. It is not the priority action for the nurse in this scenario.
Choice D rationale: Applying antiembolic stockings is a preventive measure for deep vein thrombosis, but it is not the priority action in this case. Ensuring the client's safety during surgery, specifically by preventing aspiration, takes precedence due to the client's high blood alcohol level.
Correct Answer is B
Explanation
The priority action for a nurse caring for an older adult client who is suspected of having septicemia is to obtain a blood specimen for culture and sensitivity testing.
This test will help identify the specific microorganism causing the infection and determine the most effective antibiotic treatment.
Choice A is incorrect because while a WBC count with differential can provide information about the presence of an infection, it does not identify the specific microorganism causing the infection.
Choice C is incorrect because while obtaining a history to determine recent injuries can provide useful information, it is not the priority action.
Choice D is incorrect because while administering a broad-spectrum antibiotic may be necessary, it should not be done before obtaining a blood specimen for culture and sensitivity testing.
