A nurse is caring for a child who is postoperative following surgical correction of Tetralogy of Fallot. Which of the following findings should the nurse identify as an indication of heart failure?

Choice A reason: Constipation is not typically associated with nephrotic syndrome. It may be related to dietary factors, dehydration, or other gastrointestinal issues.

Choice B reason: Increased abdominal girth can be an indication of nephrotic syndrome due to the accumulation of fluid in the abdomen (ascites) as a result of low albumin levels in the blood, which is a characteristic of this condition.

Choice C reason: Irritability can be a non-specific symptom and may be caused by a variety of factors. It is not a direct indication of nephrotic syndrome.

Choice D reason: Increased urinary output is not characteristic of nephrotic syndrome. In fact, decreased urine output may be observed due to the loss of protein in the urine and subsequent fluid retention in the body.

Choice A reason: Contact precautions are used for infections that spread by direct or indirect contact with the patient or the patient's environment. While important, they are not the primary precaution for pertussis.

Choice B reason: Airborne precautions are used for diseases that are transmitted through the air over long distances, such as tuberculosis. Pertussis does not typically require airborne precautions.

Choice C reason: Protective precautions are used to protect immunocompromised patients from being infected by others. This is not applicable for a child with pertussis, who is the source of infection.

Choice D reason: Droplet precautions are used for diseases that are transmitted through large droplets expelled during coughing, sneezing, or talking. Pertussis, also known as whooping cough, is primarily spread through respiratory droplets, making droplet precautions the appropriate choice.
