When caring for a patient with Alzheimer's disease, the nurse would assess the patient for which two common infection-related complications due to chronic dementia?

Choice A reason: Liver cirrhosis is characterized by chronic liver damage leading to scarring and liver failure. The typical lab findings for liver cirrhosis would include elevated liver enzymes (ALT, AST), bilirubin, and low albumin levels, which are not mentioned in the given test results.

Choice B reason: Acute hepatitis refers to the inflammation of the liver, usually caused by viral infections or toxins. Lab results consistent with acute hepatitis would show elevated liver enzymes (ALT, AST) significantly higher than normal, which are not provided in the text.

Choice C reason: Cholecystitis is the inflammation of the gallbladder, often due to gallstones. Lab findings for cholecystitis may include elevated white blood cell count and sometimes mild elevation of liver enzymes, but not the specific elevated levels of serum amylase and lipase.

Choice D reason: Acute pancreatitis is an inflammation of the pancreas, and the hallmark lab findings include significantly elevated serum amylase and lipase levels. The test results show serum amylase of 920 units/L (reference: 30-220 units/L) and serum lipase of 704 units/L (reference: 0-160 units/L), which are highly indicative of acute pancreatitis. Elevated serum glucose and low serum calcium levels are also consistent with this diagnosis.

Choice A reason: Checking the patient's temperature is important for assessing the severity of the pneumonia and monitoring for fever, but it is not the priority action before administering the first dose of vancomycin.

Choice B reason: Obtaining sputum cultures is the priority action because it allows for the identification of the causative organism and determination of its antibiotic susceptibility. This helps ensure that the prescribed antibiotic is appropriate for the patient's infection. Cultures should be obtained before starting antibiotic therapy to avoid interference with culture results.

Choice C reason: Checking the patient's blood pressure is important for overall patient assessment and monitoring, especially considering potential side effects of vancomycin. However, it is not the primary action needed before the first dose of the antibiotic.

Choice D reason: Drawing a blood specimen to evaluate the white blood cell count is useful for assessing the severity of the infection and the patient's immune response. However, this can be done after obtaining the sputum cultures and is not the immediate priority before administering the antibiotic.
