Which treatment will the physician write an order for? The physician will most likely write an order for which treatment? A client is admitted with nausea, vomiting, and diarrhea. His blood pressure on admission is 74/30 mm Hg. The client is oliguric and his blood urea nitrogen (BUN) and creatinine levels are elevated.

When creatine levels are higher than normal, ACEI drugs (Angiotensin-converting enzyme inhibitor) can help control blood pressure. They can reduce protein in the urine to stop the further elevation of creatine. Ketosteril may also be used to provide the person with essential amino acids and also reduces the blood urea nitrogen, and it may help to lower the overall BUN levels.

High creatine levels indicate possible chronic kidney disease or kidney failure, or the kidneys not functioning properly. High creatine levels can also cause dehydration. Oliguria is one of the symptoms of renal failure, and it is frequently acute.

Start i.v. fluids with a normal saline solution bolus followed by a maintenance dose.-rationale: the client is in prerenal failure caused by hypovolemia. i.v. fluids should be given with a bolus of normal saline solution followed by maintenance i.v. therapy. this treatment should rehydrate the client, causing his blood pressure to rise, his urine output to increase, and the bun and creatinine levels to normalize. the client wouldnt be able to tolerate oral fluids because of the nausea, vomiting, and diarrhea. the client isnt fluid-overloaded so his urine output wont increase with furosemide, which would actually worsen the clients condition. the client doesnt require dialysis because the oliguria and elevated bun and creatinine levels are caused by dehydration.
