Michael has been diagnosed with frontal lobe abnormalities. As part of his care and evaluation, it is important to understand the specific functions that the frontal lobe is responsible for.

A. Esophageal: Esophageal variceal bleeding is the most common and serious complication of portal hypertension. Increased pressure in the portal venous system leads to the formation of varices in the esophagus, which can rupture and cause life-threatening hemorrhage.

B. Intestinal: While portal hypertension can cause changes in intestinal blood flow, it is not the most common site for clinically significant bleeding. Intestinal bleeding related to portal hypertension is much less frequent than esophageal variceal bleeding.

C. Duodenal: Duodenal bleeding is more commonly associated with peptic ulcer disease rather than portal hypertension. It is not a typical manifestation of increased portal venous pressure.

D. Rectal: Rectal bleeding may occur due to hemorrhoids or portal hypertensive colopathy, but it is less common and less life-threatening compared to esophageal varices in portal hypertension.

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.
