A nurse is caring for a client who reports heart palpitations. An ECG confirms the client is experiencing ventricular tachycardia (VT). The nurse should anticipate the need for taking which of the following actions?
Elective cardioversion
Defibrillation
CPR
Radiofrequency catheter ablation
The Correct Answer is A
The correct answer is: A. Elective cardioversion
Choice A reason:
Elective cardioversion is a medical procedure that is used to restore a normal heart rhythm in patients experiencing certain types of arrhythmias, including ventricular tachycardia (VT), when they are stable. It involves the delivery of a controlled electric shock to the heart, which is synchronized with the heart's electrical activity to convert the abnormal rhythm back to a normal sinus rhythm. This procedure is typically performed when VT is not causing hemodynamic instability and the patient is not in immediate danger.
Choice B reason:
Defibrillation is an emergency treatment for life-threatening cardiac arrhythmias, particularly ventricular fibrillation (VF) or pulseless ventricular tachycardia. It involves delivering a high-energy electric shock to the heart unsynchronized to the heart's electrical cycle, aiming to reset the heart's electrical state and allow it to reestablish an effective rhythm. In the scenario provided, where the patient is experiencing VT but not VF, defibrillation would not be the first line of action unless the VT deteriorates into VF or the patient becomes pulseless.
Choice C reason:
CPR, or cardiopulmonary resuscitation, is a lifesaving technique useful in many emergencies, including heart attack or near drowning, in which someone's breathing or heartbeat has stopped. In the case of VT, if the patient is conscious and has a pulse, CPR is not indicated. CPR would only be necessary if the patient's heart stops beating (cardiac arrest) as a result of the VT.
Choice D reason:
Radiofrequency catheter ablation is a procedure used to treat some types of arrhythmias, including VT, by destroying the area of heart tissue that is causing the abnormal heart rhythm. This treatment is generally considered when medication is ineffective or not tolerated, or in recurrent VT. It is not typically the first line of treatment in an acute setting where the patient is stable and experiencing VT.

Correct Answer is B
Explanation
Choice a) is incorrect because vesicles on the skin are a sign of cutaneous anthrax, not inhalation anthrax. Cutaneous anthrax is caused by direct contact with anthrax spores through a break in the skin. It causes a painless, black, necrotic lesion on the affected area.
Choice b) is correct because respiratory failure is a sign of inhalation anthrax, which is the most deadly form of anthrax. Inhalation anthrax is caused by breathing in anthrax spores that enter the lungs and spread to the bloodstream. It causes severe breathing problems, chest pain, shock, and death.
Choice c) is incorrect because sloughing of skin is a sign of necrotizing fasciitis, not inhalation anthrax. Necrotizing fasciitis is a rare bacterial infection that destroys the soft tissue under the skin. It causes severe pain, swelling, redness, blisters, and gangrene.
Choice d) is incorrect because flu-like symptoms are not specific to inhalation anthrax. Flu-like symptoms can be caused by many other conditions, such as influenza, common cold, or COVID-19. Flu-like symptoms include fever, cough, sore throat, headache, and muscle aches.
Correct Answer is ["A","B"]
Explanation
Choice A: Inspecting the electrode pads is an action that the nurse should take. The electrode pads are adhesive patches that atach to the skin and connect to the ECG machine. The nurse should inspect the electrode pads for expiration date, cleanliness, and stickiness, and replace them if necessary. The nurse should also check for any signs of skin irritation or allergy from the electrode pads.
Choice B: Instructing the client not to talk during the test is an action that the nurse should take. Talking during the test can interfere with the ECG recording and cause artifacts or false readings. The nurse should instruct the client to remain still and quiet during the test, and avoid any movements or activities that can affect the heart rate or rhythm, such as coughing, deep breathing, or shivering.
Choice C: Administering an analgesic prior to the procedure is not an action that the nurse should take. An analgesic is a pain reliever that can be given orally, intravenously, or topically. An analgesic is not necessary for an ECG, as it is a noninvasive and painless procedure. An analgesic can also alter the heart rate or rhythm and affect the ECG results. The nurse should only administer an analgesic if prescribed by the provider for another reason.
Choice D:It is more common to use alcohol swabs, and not water, to clean the skin as they are better at removing oils and ensuring good adhesion of the electrodes.
Choice E: Keeping the client NPO after midnight is not an action that the nurse should take. NPO means nothing by mouth, which is a restriction of food and fluids before certain procedures or surgeries. NPO is not required for an ECG, as it does not involve any anesthesia or sedation. The nurse should allow the client to eat and drink normally before and after the test, unless instructed otherwise by the provider.
