A nurse is reviewing a client's cardiac monitor. Which of the following findings should the nurse identify as an indication for synchronized cardioversion?
Asystole
Ventricular fibrillation
Pulseless ventricular tachycardia
Atrial fibrillation
The Correct Answer is D
A. Asystole: Synchronized cardioversion is ineffective for asystole because there is no electrical activity to reset. The appropriate intervention for asystole is immediate CPR and administration of epinephrine.
B. Ventricular fibrillation: Defibrillation, not synchronized cardioversion, is the appropriate treatment for ventricular fibrillation because it is a pulseless, chaotic rhythm that requires immediate high-energy shocks.
C. Pulseless ventricular tachycardia: Pulseless ventricular tachycardia is treated with defibrillation rather than synchronized cardioversion, as there is no coordinated cardiac activity to synchronize with. CPR and advanced cardiac life support (ACLS) protocols should be initiated.
D. Atrial fibrillation: Synchronized cardioversion is indicated for atrial fibrillation, particularly when it is associated with hemodynamic instability. Cardioversion helps restore a normal sinus rhythm by delivering a shock synchronized to the R wave of the QRS complex.

Correct Answer is C
Explanation
A. "I cook my partner's favorite foods.": Preparing meals can be a way to show love and care, but it does not necessarily indicate effective coping. It may serve as a distraction, but it does not address emotional or social well-being.
B. "I make a list of all the things I need to do.": Creating lists can help with organization, but it does not directly reflect emotional coping. It may indicate a focus on tasks rather than emotional processing or seeking support.
C. "I have lunch with my friends once a week.": Maintaining social connections is a sign of effective coping, as it provides emotional support and an opportunity to share feelings. Engaging in enjoyable activities outside of caregiving responsibilities helps reduce stress.
D. "I am unable to fall asleep right away.": Difficulty sleeping is a common response to stress but suggests ongoing emotional distress rather than effective coping. Persistent sleep disturbances may require further assessment and support.
Correct Answer is D
Explanation
A. "I should use a heating pad when my feet are cold.": Clients with diabetes mellitus may have reduced sensation due to peripheral neuropathy. Using a heating pad increases the risk of burns or injury due to the inability to perceive excessive heat.
B. "I should plan to remain barefoot while I am at home.": Walking barefoot increases the risk of foot injuries, which can lead to infections and complications such as diabetic ulcers. Clients should always wear well-fitting shoes, even at home, to protect their feet.
C. "I should apply lotion between my toes twice a day.": Moisturizing the feet is important to prevent dryness and cracking, but applying lotion between the toes can create excess moisture, increasing the risk of fungal infections.
D. "I should file the edges of my toenails after trimming them.": Filing the edges helps smooth sharp corners, reducing the risk of ingrown toenails and foot injuries, which can be difficult to heal in individuals with diabetes.
