Which of the following statements is not a typical manifestation of SIADH?

A. Anorexia is a common manifestation of SIADH due to the effects of hyponatremia (low sodium levels) and fluid retention.

B. Edema of fluid overload is not a typical manifestation of SIADH. While SIADH leads to fluid retention due to excess antidiuretic hormone (ADH), the excess fluid is typically intracellular and does not cause peripheral edema as seen in conditions like heart failure or nephrotic syndrome.

C. Vomiting is a common manifestation of SIADH, often related to the effects of hyponatremia, which can irritate the gastrointestinal system.

D. Nausea is also a common symptom of SIADH due to the imbalance of electrolytes, particularly low sodium levels, which can affect the brain and lead to nausea.

A. Increased chloride levels, also known as hyperchloremia, can occur in metabolic acidosis as part of the body's attempt to balance acid-base status.

B. All of the options listed contribute to metabolic acidosis. Increased metabolic acids, decreased bicarbonate, and increased chloride levels can all be present in metabolic acidosis, making this the correct answer.

C. Increased metabolic acids, such as lactic acid or ketoacids, are a key feature of metabolic acidosis.

D. In metabolic acidosis, bicarbonate levels decrease as the body compensates by buffering excess acid with available bicarbonate.
