A 40-year-old client is admitted to the hospital after experiencing 3 days of extreme vomiting. The doctor reviews the lab results and notes that the hemoglobin and hematocrit are elevated. What is the likely cause of these abnormal lab findings?

The cause is likely Manifestation of dehydration

Explanation:

The hematocrit measures the red cell mass in a 100-mL plasma volume. The hematocrit may be deceptive because it varies with the quantity of extracellular fluid, rising with dehydration and falling with over expansion of extracellular fluid volume. The client is manifesting an abnormal elevation as a result of fluid loss.
