Respiratory infections

The CD is a 28-year-old administrative hospital worker who presented to the emergency room complaining of headaches and shortness of breath. She was admitted to the hospital for evaluation when she was found to have a blood pressure of 170/110 mm Hg and mild congestive heart failure (CHF) by chest X-ray. CD reports that over the past year, her weight has increased by about 10  pounds (4.5 kg), although her dietary intake has remained unchanged or even lower due to her desire for weight loss.

and has no knowledge of a family history of renal disease. She is currently not taking any medications, vitamins, minerals, or herbal supplements and has no known drug or food allergies.

Dialysis Treatment Plans

The CD received a temporary dialysis catheter and underwent two hemodialysis treatments in the hospital. During her hospitalization, she was educated on all dialysis modalities available and chose

peritoneal dialysis (PD). She was discharged from the hospital with plans for a peritoneal dialysis

catheter to be inserted the following week. She was educated on a “renal” diet by the hospital dietitian and medications were prescribed as well. She was to dialyze in the in-center dialysis facility

close to the hospital.
