Question

A patient presents with fever, N/V, diarrhea, decreased urine output for 48 hours, orthostatic hypotension, tachycardia, dehydration on physical examination, abdominal pain, high serum glucose, high white blood cells count, high blood urea nitrogen, and high creatinine. What is the most likely diagnosis?

1) Diabetes mellitus
2) Acute kidney injury
3) Gastroenteritis
4) Urinary tract infection

Answer 1

The most likely diagnosis for a patient presenting with the mentioned symptoms is acute kidney injury. The correct option is 2.

Step-by-step explanation:

The most likely diagnosis for a patient presenting with fever, N/V, diarrhea, decreased urine output for 48 hours, orthostatic hypotension, tachycardia, dehydration on physical examination, abdominal pain, high serum glucose, high white blood cells count, high blood urea nitrogen, and high creatinine is Acute kidney injury.

Acute kidney injury is characterized by a rapid decline in kidney function, which leads to decreased urine output, electrolyte imbalances, and elevated levels of blood urea nitrogen and creatinine. The symptoms described, such as orthostatic hypotension and tachycardia, are common manifestations of hypovolemia and dehydration secondary to acute kidney injury. The high white blood cell count is suggestive of an underlying infection, which can be a complication of acute kidney injury.
