A nurse in an urgent care center is assessing a client who reports a sudden onset of irregular palpitations, fatigue, and dizziness. The nurse finds a rapid and irregular heart rate with a significant pulse deficit. Which of the following dysrhythmias should the nurse expect to find on the ECG?
Sinus bradycardia
Sinus tachycardia
Atrial fibrillation
First-degree AV block
The Correct Answer is C
Choice A Reason: This is incorrect. Sinus bradycardia is a slow and regular heart rate that originates from the sinus node. It does not cause irregular palpitations, fatigue, or dizziness, unless the heart rate is very low or the client has underlying cardiac disease.
Choice B reason: This is incorrect. Sinus tachycardia is a fast and regular heart rate that originates from the sinus node. It may cause fatigue or dizziness, but not irregular palpitations or pulse deficit.
Choice C Reason: This is correct. Atrial fibrillation is a fast and irregular heart rate that originates from multiple foci in the atria. It causes irregular palpitations, fatigue, dizziness, and pulse deficit due to ineffective atrial contractions and variable ventricular response.
Choice D Reason: This is incorrect. First-degree AV block is a delay in the conduction of impulses from the atria to the ventricles. It does not affect the heart rate or rhythm, and does not cause any symptoms.

Correct Answer is D
Explanation
Choice A Reason: This is incorrect. Opioids are not indicated for a client who is emerging from a coma, as they can cause respiratory depression, sedation, and confusion. They may also mask the signs of increased intracranial pressure or neurological deterioration.
Choice B Reason: This is incorrect. Darkening the room may not be helpful for a client who is emerging from a coma, as it may increase their disorientation and agitation. The nurse should provide adequate lighting and orient the client to time, place, and person frequently.
Choice C Reason: This is incorrect. Applying restraints may worsen the restlessness and agitation of a client who is emerging from a coma, as they may perceive them as a threat or a restriction. Restraints may also increase the risk of injury, infection, or skin breakdown. The nurse should use restraints only as a last resort and with a physician's order.
Choice D Reason: This is correct. Reducing stimuli is an appropriate intervention for a client who is emerging from a coma, as it can help calm them and prevent sensory overload. The nurse should limit noise, visitors, and unnecessary procedures, and provide a quiet and comfortable environment.
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.
