A client with atrial fibrillation is scheduled for an elective cardioversion.

The nurse prepares for the procedure by inserting two intravenous (IV) catheters and connecting the monitoring lead wires to the client.
Which action is most crucial for the nurse to take before initiating the cardioversion?

Activate the synchronization mode.

Choose a monitor lead with a tall R wave.

Administer the prescribed sedative.

Verify the prothrombin time (PT).

Answer and Explanation

The Correct Answer is C

Choice A rationale
Activating the synchronization mode is important during cardioversion to avoid delivering a shock during the vulnerable period of cardiac repolarization, which could potentially cause a life-threatening arrhythmia. However, it is not the most crucial action.
Choice B rationale
Choosing a monitor lead with a tall R wave can help ensure that the cardioverter-defibrillator can sense the patient’s intrinsic cardiac activity. However, this is not the most crucial action.
Choice C rationale
Administering the prescribed sedative is the most crucial action before initiating cardioversion. Sedation is necessary to ensure patient comfort and cooperation during the procedure, as cardioversion can be painful.
Choice D rationale

Verifying the prothrombin time (PT) is important in patients receiving anticoagulation therapy, as atrial fibrillation increases the risk of thrombus formation. However, it is not the most crucial action before initiating cardioversion.

Correct Answer is ["D","E","F"]

Explanation

Choice D rationale
Involving the mother in the decision-making process can help alleviate some of the stress associated with caregiving. It allows the mother to maintain some control over her care and ensures that her needs and preferences are being met.
Choice E rationale
It is normal to have mixed feelings when caring for a loved one. Acknowledging these feelings can be an important part of managing caregiver stress.
Choice F rationale
Taking time for oneself and maintaining other relationships is crucial for caregiver well-being. It can help prevent burnout and improve the quality of care provided to the mother.

A. Respiratory alkalosis. B. Respiratory acidosis. C. Metabolic alkalosis. D. Metabolic acidosis.

Correct Answer is A

Explanation

Choice A rationale
Hyperventilation leads to a decrease in the amount of carbon dioxide (CO2) in the blood. This causes the pH of the blood to increase, resulting in respiratory alkalosis.
Choice B rationale
Respiratory acidosis is caused by a buildup of CO2 in the blood, typically due to hypoventilation (under-breathing). This is not consistent with the patient’s symptoms of hyperventilation.
Choice C rationale
Metabolic alkalosis is typically caused by a significant loss of acid from the body, such as from prolonged vomiting. This is not consistent with the patient’s symptoms.

Choice D rationale
Metabolic acidosis is typically caused by an increase in acid production within the body or a loss of bicarbonate from the body, such as in diabetic ketoacidosis or kidney disease. This is not consistent with the patient’s symptoms.
