A 51 year old male has been diagnosed with alcohol-induced liver disease. He admits to the nurse he does not understand what the liver does in the body. Which of these statements best explains the liver's function?

A. Optimizing pain: While pain management is important in any patient care plan, acute kidney injury typically does not cause significant pain unless associated with another condition such as obstruction or infection. It is not a primary focus unless the patient reports discomfort requiring intervention.

B. Protecting from falls: Fall prevention is a general safety measure but is not a specific priority related to AKI management unless the patient has associated risks like altered mental status, weakness, or dialysis-related hypotension. It is not a primary priority in early AKI care planning.

C. Monitoring electrolyte levels: AKI commonly leads to imbalances in potassium, sodium, calcium, and phosphorus due to impaired renal clearance. Hyperkalemia in particular poses serious cardiac risks, making electrolyte monitoring a top priority to prevent complications such as arrhythmias.

D. Assessing fluid balance: AKI affects the kidneys’ ability to excrete or conserve fluid, resulting in potential fluid overload or dehydration. Accurate intake and output tracking, daily weights, and edema assessment are essential to guide treatment and prevent respiratory or cardiovascular compromise.

E. Promoting infection control: Infection is both a potential cause and a complication of AKI, especially in hospitalized or catheterized patients. Maintaining strict aseptic technique, monitoring for signs of infection, and preventing sepsis are critical components of AKI management.

A. Imaging tests are likely to reveal scarring and deformation of the renal calices and pelvis: These findings are more typical of chronic pyelonephritis, which results from repeated or persistent kidney infections. Acute pyelonephritis usually presents with more subtle imaging changes.

B. Most cases of acute pyelonephritis are attributable to poorly controlled hypertension: While hypertension can complicate kidney disease, it is not a common cause of acute pyelonephritis. Most cases are due to ascending urinary tract infections, particularly from organisms like E. coli.

C. Flank pain, dysuria and nausea and vomiting are likely assessment findings: These are hallmark symptoms of acute pyelonephritis. Flank pain results from inflammation of the renal capsule, while dysuria and systemic symptoms like nausea, vomiting, and fever indicate infection.

D. The infection in the kidney is most likely a manifestation of a systemic infection: Acute pyelonephritis is typically caused by local ascending infections from the lower urinary tract, not systemic bacteremia. Though it can lead to systemic illness if not treated, its origin is usually localized.
