A nurse is caring for a 78-year-old client who was recently admitted from the emergency room and is reporting weakness. Exhibits Drag words from the choices below to fill in each blank in the following sentence The nurse has reviewed the client's medical record. The client is at risk for developing dropdown and dropdown.

Rationale for Correct Answers: Metabolic acidosis: The client’s ABG shows a low pH of 7.33 and bicarbonate (HCO3) of 19 mEq/L, indicating primary metabolic acidosis, likely due to prolonged diarrhea and bicarbonate loss through the GI tract. Hypernatremia: Serum sodium is elevated at 149 mEq/L, likely resulting from fluid loss due to persistent diarrhea and poor fluid intake, which concentrates serum sodium. Rationale for Incorrect Answers: Hypermagnesemia: The magnesium level is 1.8 mEq/L, which is within the normal range. There is no indication of magnesium excess, and the client has not received supplements or renal impairment. Hypervolemia: The client shows signs of volume depletion, including hypotension, dry mucous membranes, and poor skin turgor. Urine output is low, supporting fluid loss rather than overload. Hyperkalemia: Although potassium is at the upper normal limit (5.0 mEq/L), there’s no current evidence of cellular lysis, renal failure, or acidosis severe enough to cause clinically significant hyperkalemia. Metabolic alkalosis: The client’s ABG values do not support metabolic alkalosis. There is no vomiting or gastric suction to suggest bicarbonate retention; instead, the client has diarrhea leading to acid loss.
