The nurse is caring for an adult patient who has gone into ventricular fibrillation. When assisting with defibrillating the patient, what must the nurse do?
- A. Maintain firm contact between paddles and patient skin.
- B. Apply a layer of water as a conducting agent.
- C. Call all clear once before discharging the defibrillator.
- D. Ensure the defibrillator is in the sync mode.
Correct Answer: A
Rationale: When defibrillating an adult patient, the nurse should maintain good contact between the paddles and the patients skin to prevent arcing, apply an appropriate conducting agent (not water) between the skin and the paddles, and ensure the defibrillator is in the nonsync mode. Clear should be called three times before discharging the paddles.

The nurse is caring for a patient who has had a biventricular pacemaker implanted. When planning the patients care, the nurse should recognize what goal of this intervention?
- A. Resynchronization
- B. Defibrillation
- C. Angioplasty
- D. Ablation
Correct Answer: A
Rationale: Biventricular (both ventricles) pacing, also called resynchronization therapy, may be used to treat advanced heart failure that does not respond to medication. This type of pacing therapy is not called defibrillation, angioplasty, or ablation therapy.
The nurse caring for a patient whose sudden onset of sinus bradycardia is not responding adequately to atropine. What might be the treatment of choice for this patient?
- A. Implanted pacemaker
- B. Trancutaneous pacemaker
- C. ICD
- D. Asynchronous defibrillator
Correct Answer: B
Rationale: If a patient suddenly develops a bradycardia, is symptomatic but has a pulse, and is unresponsive to atropine, emergency pacing may be started with transcutaneous pacing, which most defibrillators are now equipped to perform. An implanted pacemaker is not a time-appropriate option. An asynchronous defibrillator or ICD would not provide relief.
A patient has undergone diagnostic testing and received a diagnosis of sinus bradycardia attributable to sinus node dysfunction. When planning this patients care, what nursing diagnosis is most appropriate?
- A. Acute pain
- B. Risk for unilateral neglect
- C. Risk for activity intolerance
- D. Risk for fluid volume excess
Correct Answer: C
Rationale: Sinus bradycardia causes decreased cardiac output that is likely to cause activity intolerance. It does not typically cause pain, fluid imbalances, or neglect of a unilateral nature.
The nurse is assessing a patient who had a pacemaker implanted 4 weeks ago. During the patients most recent follow-up appointment, the nurse identifies data that suggest the patient may be socially isolated and depressed. What nursing diagnosis is suggested by these data?
- A. Decisional conflict related to pacemaker implantation
- B. Deficient knowledge related to pacemaker implantation
- C. Spiritual distress related to pacemaker implantation
- D. Ineffective coping related to pacemaker implantation
Correct Answer: D
Rationale: Depression and isolation may be symptoms of ineffective coping with the implantation. These psychosocial symptoms are not necessarily indicative of issues related to knowledge or decisions. Further data would be needed to determine a spiritual component to the patients challenges.
The nurse is writing a plan of care for a patient with a cardiac dysrhythmia. What would be the most appropriate goal for the patient?
- A. Maintain a resting heart rate below 70 bpm.
- B. Maintain adequate control of chest pain.
- C. Maintain adequate cardiac output.
- D. Maintain normal cardiac structure.
Correct Answer: C
Rationale: For patient safety, the most appropriate goal is to maintain cardiac output to prevent worsening complications as a result of decreased cardiac output. A resting rate of less than 70 bpm is not appropriate for every patient. Chest pain is more closely associated with acute coronary syndrome than with dysrhythmias. Nursing actions cannot normally influence the physical structure of the heart.
