A 65-year-old male patient presents with sudden onset of oliguria and signs of dehydration His blood pressure is 90/60 mmHg, heart rate is 110 bpm and he has poor skin turgor. Laboratory results show elevated blood urea nitrogen (BUN and creatinine levels. Which of the following is the most likely cause of his acute kidney injury (AKI)?
Hypovolemia leading to decreased renal perfusion
Acute tubular necrosis
Urinary tract obstruction
Chronic kidney disease
The Correct Answer is A
A. Hypovolemia leading to decreased renal perfusion. Hypovolemia from dehydration and low blood pressure reduces blood flow to the kidneys, resulting in pre-renal AKI, characterized by elevated BUN and creatinine.
B. Acute tubular necrosis. Acute tubular necrosis may cause AKI but is often due to prolonged hypoperfusion, nephrotoxic drugs, or ischemia, not the immediate presentation seen here.
C. Urinary tract obstruction. A urinary tract obstruction leads to post-renal AKI, often with symptoms like flank pain or difficulty urinating, not dehydration and low blood pressure.
D. Chronic kidney disease. Chronic kidney disease is a long-term condition and would not cause the acute symptoms or sudden onset of AKI as seen in this patient.

Correct Answer is B
Explanation
A. Keep the patient NPO (nothing by mouth) until the T-tube is removed. Patients are generally kept NPO initially but may resume clear liquids and progress to a regular diet based on tolerance; NPO status is not required until the T-tube is removed.
B. Monitor the tube drainage and document the amount and color. Monitoring and documenting drainage from the T-tube is crucial to assess biliary function and ensure that the bile is draining properly, indicating no obstruction.
C. Ensure the tube is clamped for 8 hours each day. Clamping may be done before tube removal to test the body’s tolerance to bile drainage, but it should be done only as per physician orders, not routinely for 8 hours each day.
D. Flush the T-tube with normal saline every 4 hours. Flushing a T-tube is generally not done routinely as it could disrupt the flow of bile and cause complications.
Correct Answer is C
Explanation
A. Administering pain medication: Pain management is essential, but in this case, the primary concern is potential airway compromise due to inhalation injury, which should be addressed first.
B. Applying a cool, wet cloth to burned areas: Cooling burned areas can help with pain and reduce burn severity but is not the priority in a case of suspected inhalation injury with airway compromise.
C. Administering high-flow oxygen via a non-rebreather mask: This client is at high risk for respiratory compromise due to inhalation injury; administering high-flow oxygen is the priority to ensure adequate oxygenation.
D. Initiating intravenous fluid resuscitation: Fluid resuscitation is essential for burn patients but is not the immediate priority over addressing potential airway and oxygenation issues.
