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).
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 B
Explanation
Choice A rationale
Gastric lavage is a procedure that involves the insertion of a tube into the stomach to remove its contents and is typically used in cases of poisoning or drug overdose. However, it should not be the first action taken. The type of chemical exposure needs to be determined first to guide appropriate treatment.
Choice B rationale
Determining the type of chemical exposure is crucial as it guides the subsequent steps in management. Different chemicals can have different effects on the body and require different treatments.
Choice C rationale
While assessing for altered sensorium is important in a child exposed to chemicals, it is not the first action. The nurse needs to identify the type of chemical the child was exposed to in order to anticipate potential complications and guide treatment.
Choice D rationale
Calling the poison control emergency number is an important step in managing a case of chemical exposure. However, having information about the type of chemical the child was exposed to can make this call more effective.
Correct Answer is A
Explanation
Choice A rationale
Inquiring about the frequency of falls in recent months is an important part of a functional assessment for an older adult patient reporting decreased strength in knees and handgrips. Falls can be a sign of decreased muscle strength and balance, which can be associated with aging and certain medical conditions.
Choice B rationale
Sundowning, or increased confusion and agitation in the late afternoon and evening, is a symptom often associated with dementia, not necessarily with decreased strength in knees and handgrips.
Choice C rationale
While discussing end-of-life care options is an important aspect of comprehensive patient care, it is not directly related to the patient’s reported symptoms of decreased strength.
Choice D rationale
Requesting the patient to lie as still as possible for the assessment may not provide comprehensive information about the patient’s functional mobility and strength.
