A nurse is caring for a client who has a cardiopulmonary arrest. The nurse anticipates the emergency response team will administer which of the following medications if the client's restored rhythm is symptomatic bradycardia?

Choice A: Provide frequent oral and nares care is the correct action for the nurse to take. Oral and nares care can help prevent infection, dryness, and irritation of the mucous membranes, which can be damaged by the pressure and friction of the tube. The nurse should also monitor the tube position, secure it with tape, and keep scissors at the bedside in case of emergency deflation.

Choice B: Keep the client in a supine position is not the correct action for the nurse to take. The supine position can increase the risk of aspiration, regurgitation, and gastric distension, which can worsen the bleeding and compromise the airway. The nurse should elevate the head of the bed to at least 30 degrees and use a semi-Fowler's or high-Fowler's position.

Choice C: Ambulating the client four times per day is not the correct action for the nurse to take. Ambulation can increase abdominal pressure and dislodge the tube, which can cause bleeding and perforation. The nurse should keep the client on bed rest and use passive range-of-motion exercises to prevent complications such as thromboembolism and muscle atrophy.

Choice D: Encouraging the client to consume clear liquids is not the correct action for the nurse to take. Clear liquids can increase gastric volume and acidity, which can aggravate the bleeding and interfere with hemostasis. The nurse should maintain a nothing-by-mouth status and provide intravenous fluids and nutrition as prescribed.

Choice A: Weight gain is not a manifestation of left-sided heart failure. Weight gain is more likely to occur in right-sided heart failure, as the blood backs up in the systemic circulation and causes fluid retention and edema in the body.

Choice B: Anorexia is not a manifestation of left-sided heart failure. Anorexia is a loss of appetite, which can have many causes, such as psychological disorders, infections, medications, or cancer. Left-sided heart failure does not directly affect appetite, but it can cause nausea, fatigue, and weakness.

Choice C: A distended abdomen is not a manifestation of left-sided heart failure. A distended abdomen is more likely to occur in right-sided heart failure, as the blood backs up in the portal vein and causes increased pressure in the liver and spleen. This can lead to hepatomegaly, splenomegaly, ascites, and varices.

Choice D: Breathlessness is a manifestation of left-sided heart failure. Breathlessness, or dyspnea, is a sensation of difficulty breathing or shortness of breath. Breathlessness occurs in left-sided heart failure, as the blood backs up in the lungs and causes pulmonary congestion and edema. This impairs gas exchange and reduces oxygen delivery to the tissues.
