Q & A
What is acute kidney injury (AKI)?
-Acute kidney injury, also known as AKI, is a sudden change in kidney function that typically occurs within about 48 hours. It can lead to a buildup of electrolytes and waste in the body, which are normally filtered out by the kidneys.
What are the three types of injuries associated with acute kidney injury?
-The three types of injuries associated with AKI are pre-renal, intrarenal, and post-renal. Pre-renal involves issues before the kidney, such as decreased blood flow. Intrarenal refers to damage occurring within the kidney itself. Post-renal involves issues after the kidney, such as blockages in the ureters or bladder.
What is the role of kidneys in the body?
-Kidneys are vital organs that filter blood to remove excess fluid, waste products, and electrolytes that the body doesn't need. They maintain a balance of these substances in the body and return necessary components back into circulation.
What are some causes of pre-renal AKI?
-Pre-renal AKI can be caused by hypovolemia (low blood volume), third spacing (fluid accumulation in the body's tissues), hemorrhage (blood loss), blockages in the renal artery, and systemic vasodilation (widening of blood vessels).
How can one identify if a patient is experiencing AKI?
-Patients with AKI may exhibit symptoms such as decreased urine output, increased blood urea nitrogen (BUN) and creatinine levels, changes in electrolytes, hyperkalemia (high potassium levels), edema (fluid retention), and fatigue.
What are the phases of AKI?
-The phases of AKI include the onset phase (hours to days), oliguric phase (one to three weeks), diuretic phase (variable duration), and recovery phase (which can last from months to years).
What diagnostic tests are used to evaluate a patient with suspected AKI?
-Diagnostic tests for AKI include blood tests to check BUN and creatinine levels, urinalysis, EKG for hyperkalemia, and imaging studies such as X-rays, CT scans, or ultrasounds to identify any structural issues. In some cases, a renal biopsy may be performed.
What are the nursing interventions for a patient with AKI?
-Nursing interventions for AKI include monitoring vital signs, EKG, and telemetry, checking blood and urine work, managing fluid intake and output, providing a high-calorie, low-protein diet, and monitoring for signs of improvement or complications.
Why is it important to monitor a patient's electrolyte levels during treatment for AKI?
-Electrolyte levels are crucial to monitor because AKI can cause imbalances such as hyperkalemia. Treatment with diuretics can also lead to changes in electrolyte levels, which can affect heart function and other bodily processes.
What is the significance of urine output in managing a patient with AKI?
-Urine output is a key indicator of kidney function. A decrease in urine output can signal impaired kidney function, while an increase during the diuretic phase of treatment can indicate that the kidneys are starting to eliminate excess fluid and waste.
How does the treatment for AKI differ based on the underlying cause?
-Treatment for AKI is patient-specific and targets the underlying cause. This may include fluid replacement for hypovolemia, diuretics for fluid overload, antibiotics for infections, or surgical intervention to remove blockages. The goal is to restore normal kidney function.
Outlines
😀 Understanding Acute Kidney Injury (AKI)
The first paragraph introduces the topic of acute kidney injury (AKI), emphasizing its sudden onset within approximately 48 hours. It explains the kidney's role in filtering waste and maintaining electrolyte balance. The potential progression from AKI to chronic kidney disease is mentioned, and the paragraph outlines three types of kidney injuries: pre-renal, intrarenal, and post-renal, relating to issues before, within, or after the kidney, respectively.
💡 Pre-Renal and IntraRenal Causes of AKI
The second paragraph delves into pre-renal conditions, which involve decreased blood flow to the kidneys, often due to hypovolemia, third spacing, or hemorrhage. It also discusses blockages in the renal artery and systemic vasodilation as causes. Intrarenal issues are then explored, which can stem from pre-renal conditions leading to ischemic damage, or from nephrotoxic medications, infections, and other kidney impairments.
🚨 Post-Renal Obstructions and AKI Phases
The third paragraph focuses on post-renal problems, which occur after the kidney, often due to blockages like renal calculi, trauma, or issues with the bladder and urethra. It also draws an analogy between the kidney's function and an IV pump setup to explain pre-renal, intrarenal, and post-renal issues. The paragraph concludes by outlining the phases of AKI, including onset, oliguric, diuretic, and recovery phases, and touches on the signs and symptoms patients may exhibit.
📉 Symptoms and Diagnostics of AKI
The fourth paragraph details the symptoms of AKI, such as decreased urine output, increased BUN and creatinine levels, and electrolyte imbalances like hyperkalemia. It also discusses diagnostic methods, including urinalysis, blood work, EKG, X-rays, CT scans, ultrasounds, and potentially a renal biopsy. The importance of monitoring vital signs, EKG, and the patient's response to treatment is emphasized.
🩺 Treatment and Nursing Interventions for AKI
The final paragraph addresses the treatment and nursing interventions for AKI, which are tailored to the patient's specific needs. It highlights the importance of treating the underlying cause, monitoring vital signs, EKG, blood work, urine output, and daily weight. The nursing care includes providing a high-caloric, low-protein diet, managing edema, and preparing the patient for potential dialysis if kidney function does not recover. The lecture concludes by encouraging feedback and further discussion on the topic.

Highlights
Acute kidney injury (AKI) is a sudden change in kidney function that can lead to a buildup of waste products and electrolytes in the body.
AKI is categorized into three types: pre-renal, intrarenal, and post-renal, each affecting different structures of the urinary system.
Pre-renal AKI is caused by a decrease in blood flow or volume to the kidney, often due to hypovolemia, third spacing, or hemorrhage.
Intrarenal AKI involves damage within the kidney itself, which can be due to ischemic damage, nephrotoxic medications, or infections.
Post-renal AKI occurs when there is a blockage after the kidney, such as from renal calculi, tumors, or trauma affecting the ureters, bladder, or urethra.
The phases of AKI include onset, oliguric, diuretic, and recovery, with symptoms and treatment varying between each phase.
Diagnostic tests for AKI include blood tests for BUN and creatinine levels, urinalysis, and imaging studies like X-ray, CT scan, or ultrasound.
Treatment for AKI is patient-specific and focuses on addressing the underlying cause, such as fluid replacement, diuretics, or antibiotics.
Nursing interventions for AKI patients include monitoring vital signs, EKG, daily weights, edema, and dietary management.
Patients with AKI may require emotional and psychological support due to the potential for chronic kidney disease or the need for dialysis.
An IV pump setup analogy is used to help understand the differences between pre-renal, intrarenal, and post-renal AKI.
Hypotension and systemic vasodilation can lead to decreased kidney perfusion and contribute to pre-renal AKI.
Nurses play a crucial role in monitoring and managing AKI patients, including the assessment of urine output and electrolyte balance.
The recovery phase of AKI can last from months to years, with the goal of returning the patient to their baseline kidney function.
Nephrotoxic drugs and medication dosages require careful monitoring in AKI patients due to the kidney's reduced ability to metabolize them.
The importance of early detection and intervention in AKI is emphasized to prevent progression to chronic kidney disease.
Patients with AKI may exhibit symptoms such as decreased urine output, fatigue, edema, and changes in mental status.
An EKG may reveal a peaked T wave in AKI patients, indicating hyperkalemia, which is a critical electrolyte imbalance.
