A nurse is admitting a client who has pyelonephritis. Which of the following manifestations should the nurse expect to be present during the assessment? (Select all that apply.)

Choice A rationale
Pericardiocentesis is a procedure used to remove fluid from the pericardial sac and is not typically used to treat atrial fibrillation. It is more commonly indicated for conditions such as pericardial effusion or cardiac tamponade.

Choice B rationale
Septal myectomy is a surgical intervention to remove part of the thickened septal wall that separates the ventricles of the heart. It is primarily used to treat hypertrophic cardiomyopathy, not atrial fibrillation.

Choice C rationale
A pericardial window is a procedure that creates an opening in the pericardium to allow fluid to drain into the surrounding chest cavity. This procedure is not a treatment for atrial fibrillation.

Choice D rationale
Synchronized electrical cardioversion is a procedure where a controlled electric shock is delivered to the heart to restore a normal rhythm. It is a common and effective treatment for atrial fibrillation, especially when the condition is causing significant symptoms like palpitations, lightheadedness, and shortness of breath.

Choice A rationale
Storing the medication at room temperature is a practical instruction but does not explain the therapeutic purpose of the medication, which is essential for patient understanding.

Choice B rationale
Epoetin alfa (Procrit) is used to treat anemia associated with chronic kidney disease by supplementing erythropoietin, a hormone the damaged kidneys can no longer produce effectively. This is the most informative statement for the patient's understanding of the medication's purpose.

Choice C rationale
While epoetin alfa can improve anemia and potentially improve quality of life, it does not directly delay the need for dialysis, which is determined by overall kidney function and not solely by the presence of anemia.

Choice D rationale
Epoetin alfa does not have a role in preventing AV fistula clotting. It is specifically used to stimulate red blood cell production and has no direct effect on clotting mechanisms.
