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 A
Explanation
Administering IV fluids can help maintain blood flow to the kidneys and prevent acute kidney failure.
Choice B is incorrect because inserting a urinary catheter does not prevent acute kidney failure.
Choice C is incorrect because an intravenous pyelogram is a diagnostic test and does not prevent acute kidney failure.
Choice D is incorrect because beta-blocker therapy is not used to prevent acute kidney failure.
