A nurse is caring for a client in the clinic who has a distended bladder with discomfort over the area and a sense of fullness. Which of the following tests should the nurse expect the health care provider to order to determine if the client has urinary retention? (Select all that apply.)

Choice A reason: Diabetes can increase the risk of infection, including peritonitis, due to immune system impairment.

Choice B reason: Obesity may contribute to surgical complications but is not directly linked to an increased risk of peritonitis in the context of peritoneal dialysis.

Choice C reason: Hemochromatosis can affect many organs but is not directly linked to an increased risk of peritonitis in peritoneal dialysis.

Choice D reason: Ulcerative colitis affects the colon and is not directly linked to an increased risk of peritonitis in peritoneal dialysis.

Choice A reason: Aluminum hydroxide does not primarily lower serum calcium levels. Calcium levels are typically managed in CKD patients through other medications and dietary restrictions, as hypercalcemia can occur in these patients.

Choice B reason: Aluminum hydroxide acts as a phosphate binder, which helps to lower serum phosphorus levels in patients with CKD. This is important because high phosphorus levels can lead to bone and heart problems in these patients. The normal range for serum phosphorus is approximately 2.5 to 4.5 mg/dL.

Choice C reason: Aluminum hydroxide does not have a significant effect on serum potassium levels. In CKD, potassium levels are managed through diet and other medications due to the risk of hyperkalemia, which can be life- threatening.

Choice D reason: While magaldrate contains magnesium, which could potentially worsen hypermagnesemia in CKD patients, aluminum hydroxide does not lower serum magnesium levels. Instead, it is less likely to cause elevated magnesium levels compared to magaldrate.
