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.)
Inspect the electrode pads
Instruct the client not to talk during the test
Administer an analgesic prior to the procedure
Wash the skin with plain water before placing the electrodes
Keep the client NPO after midnight
Correct Answer : A,B
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.

Correct Answer is D
Explanation
Choice A Reason: This is incorrect because these values indicate respiratory alkalosis, which is caused by hyperventilation or excess loss of carbon dioxide (PaCO2). Respiratory alkalosis increases the blood pH and decreases the HCO3- level.
Choice B Reason: This is incorrect because these values indicate metabolic alkalosis, which is caused by excess intake or retention of bases or loss of acids. Metabolic alkalosis increases the blood pH and the HCO3- level.
Choice C Reason: This is incorrect because these values indicate respiratory acidosis, which is caused by hypoventilation or excess retention of carbon dioxide (PaCO2). Respiratory acidosis decreases the blood pH and increases the HCO3- level.
Choice D Reason: This is correct because these values indicate metabolic acidosis, which is a common complication of chronic kidney disease. These values indicate metabolic acidosis, which is a common complication of chronic kidney disease. Metabolic acidosis occurs when the kidneys are unable to excrete excess acids or retain enough bicarbonate (HCO3-), which is a base that buffers the blood pH. As a result, the blood pH decreases and becomes more acidic. The normal range for blood pH is 7.35 to 7.45, for HCO3- is 22 to 26 mEq/L, and for PaCO2 is 35 to 45 mm Hg.
Correct Answer is D
Explanation
Choice A: Carvedilol is not a medication that interacts with contrast material and places the client at risk for acute kidney injury. Carvedilol is a beta-blocker that lowers blood pressure and heart rate by blocking the effects of adrenaline on the heart and blood vessels. Carvedilol does not affect kidney function or contrast excretion, but it can cause hypotension, bradycardia, or heart failure in some clients.
Choice B: Nitroglycerin is not a medication that interacts with contrast material and places the client at risk for acute kidney injury. Nitroglycerin is a vasodilator that relaxes the smooth muscles of the blood vessels and increases blood flow to the heart. Nitroglycerin does not affect kidney function or contrast excretion, but it can cause hypotension, headache, or flushing in some clients.
Choice C: Atorvastatin is not a medication that interacts with contrast material and places the client at risk for acute kidney injury. Atorvastatin is a statin that lowers cholesterol levels by inhibiting an enzyme that produces cholesterol in the liver. Atorvastatin does not affect kidney function or contrast excretion, but it can cause liver damage, muscle pain, or rhabdomyolysis in some clients.
Choice D: Metformin is a medication that interacts with contrast material and places the client at risk for acute kidney injury. Metformin is an oral antidiabetic drug that lowers blood glucose levels by decreasing hepatic glucose production and increasing insulin sensitivity. Metformin can accumulate in the kidneys and cause lactic acidosis, a life-threatening condition characterized by high levels of lactic acid in the blood. Contrast material can worsen kidney function and increase the risk of lactic acidosis in clients taking metformin. Therefore, metformin should be discontinued before and after the procedure as prescribed.
