Which of the following scenarios would MOST likely result in a falsely elevated platelet count using an electronic cell counter?

A patient presents with fatigue and pallor. Lab results show a hemoglobin level of 9 g/dL and a mean cell hemoglobin concentration (MCHC) of 30 g/dL. Which condition is MOST consistent with these findings?

A patient's anion gap is calculated to be 30 mmol/L. Which of the following conditions is LEAST likely to be the cause of this elevated anion gap?

A jaundiced patient has the following bilirubin results: Total bilirubin: 5.0 mg/dL, Direct bilirubin: 4.0 mg/dL, Calculated Indirect bilirubin: 1.0 mg/dL. These results suggest which condition?

Following significant muscle trauma, a patient's creatine kinase (CK) level is markedly elevated at 2000 U/L. Which CK isoenzyme is MOST likely responsible for this elevation?

A patient's electrolyte panel reveals the following: Sodium 125 mmol/L, Potassium 6.0 mmol/L, Chloride 90 mmol/L. Which of the following conditions would LEAST likely contribute to this electrolyte imbalance?
