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: Specific gravity is typically increased in clients who have hypovolemia, not decreased, due to the concentration of urine as the body atempts to conserve water.

Choice B reason: Creatinine levels are indeed increased in clients who have acute kidney injury, reffecting decreased kidney function and filtration.

Choice C reason: Potassium levels are not necessarily increased in clients who have polyuria. Polyuria can be associated with a variety of conditions and does not directly indicate high potassium levels.

Choice D reason: BUN, or blood urea nitrogen, is typically increased in clients who have dehydration, not decreased, due to the concentration of blood solutes as the body conserves water.

Choice A reason: Air embolism is a potential complication during hemodialysis, but it would likely present with more acute symptoms such as chest pain or difficulty breathing.

Choice B reason: Septicemia would typically present with fever and hypotension, not necessarily with headache, nausea, and restlessness.

Choice C reason: Dialysis disequilibrium syndrome can occur after hemodialysis, especially after the first treatment, and is characterized by symptoms such as headache, nausea, and restlessness.

Choice D reason: Peritonitis is a complication associated with peritoneal dialysis, not hemodialysis.
