A nurse is reinforcing teaching with an older adult client who has had a newly inserted permanent pacemaker. Which of the following manifestations should the nurse include in the teaching as a pacemaker malfunction that the client should report to the provider?
Fatigue
Increased urine output
Sneezing
Rapid pulse
The Correct Answer is A
A. Fatigue: Fatigue may indicate that the pacemaker is not working effectively to maintain an appropriate heart rate and cardiac output, which can lead to symptoms such as weakness or tiredness.
B. Increased urine output: Increased urine output is not typically a sign of pacemaker malfunction. It could be related to other conditions but not directly linked to pacemaker issues.
C. Sneezing: Sneezing is not related to pacemaker function and would not indicate a malfunction.
D. Rapid pulse: A rapid pulse may occur in other cardiac conditions but is not commonly associated with pacemaker malfunction unless it is sustained and irregular.

Correct Answer is A
Explanation
A. "Warfarin helps prevent strokes in clients who have atrial fibrillation." Atrial fibrillation increases the risk of blood clots forming in the atria, which can travel to the brain and cause a stroke. Warfarin helps reduce this risk by thinning the blood and preventing clot formation.
B. "This medication will help maintain a normal heart rhythm." Warfarin is an anticoagulant and does not affect heart rhythm. Medications like beta-blockers or antiarrhythmics are used to control rhythm.
C. "Warfarin dissolves clots in the bloodstream." Warfarin prevents new clots from forming and existing clots from growing, but it does not dissolve clots. Clot-dissolving medications, like thrombolytics, are used to dissolve clots.
D. "This medication slows the response of the ventricles to the fast-atrial impulses." Warfarin is not used to control ventricular response. Medications like beta-blockers or calcium channel blockers are used to slow the heart rate.
Correct Answer is C
Explanation
A. Complete heart block: In complete heart block (third-degree heart block), the P waves are present, but there is no communication between the atria and the ventricles. This does not match the given scenario.
B. Ventricular Fibrillation: Ventricular fibrillation involves chaotic, rapid, and irregular electrical activity in the ventricles and is life-threatening. P waves are not present, but the description in the question points more to atrial fibrillation than ventricular fibrillation.
C. Atrial fibrillation: In atrial fibrillation, P waves are absent, and the ventricular rhythm is irregular. This matches the ECG description given in the question.
D. Sinus tachycardia: Sinus tachycardia involves a fast heart rate but still retains identifiable P waves and a regular rhythm, which is not the case here.
