A nurse is assisting with obtaining an electrocardiogram (ECG) for a client who has atrial fibrillation. Which of the following actions should the nurse take? (Select all that apply.)
A. Inspect the electrode pads
Choice A: Inspectingthe 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.
B. Instruct the client not to talk during the test
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.
C. Administer an analgesic prior to the procedure
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.
D. Wash the skin with plain water before placing the electrodes
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.
E. Keep the client NPO after midnight
None

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.

Similar Questions
A nurse in the emergency department is caring for a client who reports chest pressure and shortness of breath. Which of the following laboratory tests should the nurse anticipate the provider to prescribe?
A. Troponin I
Troponin I is a laboratory test that the nurse should anticipate the provider to prescribe. Troponin I is a protein that is released into the blood when the heart muscle is damaged. Troponin I levels are elevated in clients who have acute myocardial infarction (AMI), which is a heart atack caused by a blockage of blood flow to the heart. Chest pressure and shortness of breath are common signs and symptoms of AMI. Troponin I is a specific and sensitive marker of cardiac injury and can help diagnose AMI and guide treatment.
B. Aspartate aminotransferase (AST)
Aspartate aminotransferase (AST) is not a laboratory test that the nurse should anticipate the provider to prescribe. AST is an enzyme that is found in various tissues, such as the liver, heart, skeletal muscle, and kidneys. AST levels are elevated in clients who have liver damage, hepatitis, cirrhosis, or alcohol abuse. AST levels can also be elevated in clients who have AMI, but they are not as specific or sensitive as troponin I. AST is not a reliable indicator of cardiac injury and can be influenced by other factors.
C. B-type natriuretic peptide (BNP)
B-type natriuretic peptide (BNP) is not a laboratory test that the nurse should anticipate the provider to prescribe. BNP is a hormone that is secreted by the heart when it is stretched or overloaded. BNP levels are elevated in clients who have heart failure, which is a condition in which the heart cannot pump enough blood to meet the body's needs. Shortness of breath can be a sign of heart failure, but chest pressure is not. BNP is not a specific or sensitive marker of cardiac injury and can be influenced by other factors.
D. Lipase
Lipase is not a laboratory test that the nurse should anticipate the provider to prescribe. Lipase is an enzyme that is produced by the pancreas and helps digest fats. Lipase levels are elevated in clients who have pancreatitis, which is an inflammation of the pancreas. Pancreatitis can cause abdominal pain, nausea, vomiting, and fever. Chest pressure and shortness of breath are not signs of pancreatitis. Lipase is not a specific or sensitive marker of cardiac injury and has no relation to AMI.

A nurse is performing a neurological assessment for a client who has head trauma. Which of the following assessments will give the nurse information about the function of cranial nerve III?
A. Ask the client to shrug his shoulders against passive resistance
Ask the client to shrug his shoulders against passive resistance is not an assessment that will give the nurse information about the function of cranial nerve III. This assessment will test the function of cranial nerve XI, which is the accessory nerve. The accessory nerve innervates the trapezius and sternocleidomastoid muscles, which are involved in shoulder and neck movements.
B. Instruct the client to look up and down without moving his head
Instruct the client to look up and down without moving his head is an assessment that will give the nurse information about the function of cranial nerve III. Cranial nerve III is the oculomotor nerve, which innervates four of the six extraocular muscles that control eye movements. The oculomotor nerve also controls pupil size and lens shape. By instructing the client to look up and down without moving his head, the nurse can assess the ability of the oculomotor nerve to move the eyes vertically and adjust to different distances.
C. Observe the client's ability to smile and frown
Observe the client's ability to smile and frown is not an assessment that will give the nurse information about the function of cranial nerve III. This assessment will test the function of cranial nerve VII, which is the facial nerve. The facial nerve innervates the muscles of facial expression, which are involved in smiling, frowning, blinking, and other facial movements.
D. Have the client stand with his eyes closed and touch his nose
Have the client stand with his eyes closed and touch his nose is not an assessment that will give the nurse information about the function of cranial nerve III. This assessment will test the function of cranial nerve VIII, which is the vestibulocochlear nerve. The vestibulocochlear nerve innervates the inner ear and is responsible for hearing and balance. By having the client stand with his eyes closed and touch his nose, the nurse can assess the ability of the vestibulocochlear nerve to maintain equilibrium and coordination.

A nurse is observing the closed chest drainage system of a client who is 24 hr post thoracotomy. The nurse notes slow, steady bubbling in the suction control chamber. Which of the following actions should the nurse take?
A. Check the tubing connections for leaks
Check the tubing connections for leaks is not an action that the nurse should take. Leaks in the tubing connections can cause continuous or intermitent bubbling in the water seal chamber, not in the suction control chamber. The water seal chamber is the part of the closed chest drainage system that prevents air from entering the pleural space and allows air to escape from the chest tube. The nurse should check the tubing connections for leaks if there is bubbling in the water seal chamber and tighten them if necessary.
B. Check the suction control outlet on the wall
Check the suction control outlet on the wall is not an action that the nurse should take. The suction control outlet on the wall is the source of negative pressure that helps drain fluid and air from the pleural space and maintain a patent chest tube. The suction control chamber is the part of the closed chest drainage system that regulates the amount of negative pressure applied to the chest tube. The nurse should check the suction control outlet on the wall if there is no bubbling in the suction control chamber and adjust it as prescribed.
C. Continue to monitor the client's respiratory status
Continue to monitor the client's respiratory status is an action that the nurse should take. Slow, steady bubbling in the suction control chamber is an expected finding that indicates that suction is working properly and that there are no leaks in the system. The nurse should continue to monitor the client's respiratory status and assess for signs of respiratory distress, such as dyspnea, tachypnea, cyanosis, or decreased oxygen saturation.
D. Clamp the chest tube
Clamp the chest tube is not an action that the nurse should take. Clamping the chest tube can cause a tension pneumothorax, which is a life-threatening condition characterized by a buildup of air in the pleural space that compresses the lung and shifts the mediastinum. The nurse should only clamp the chest tube temporarily and briefly for specific purposes, such as changing or troubleshooting the drainage system, or as prescribed by the provider.
