Which of the following findings should the nurse
identify as metabolic acidosis. A pH below 7.35 is an indication of acidosis. An HCO3- below 22 mEq/L is
an indication of metabolic acidosis.
The nurse is reviewing the laboratory report of a Hct 34%
client who has fluid volume excess. Which of the
following laboratory values should the nurse The nurse should identify that a client who has fluid volume excess can
expect? have a Hct level that is below the expected reference range of 37% to
47% for females or 42% to 52% for males. Fluid volume excess can cause
hemodilution and a decreased hematocrit level.
The nurse should identify that a client who has 12 to 16 g/dl for females or 14 to 18 g/dl for males.
dehydration can have a Hgb level that is above the Fluid volume excess can cause hemodilution and a decreased
expected reference range of: hemoglobin level.
The nurse should identify that a client who has 10 to 20 mg/dL. Fluid volume excess can cause a decrease in BUN.
dehydration can have a BUN that is above the
expected reference range of:
