Question

CS # 16-2

The test results on the blood drawn before the subject went into cardiac arrest show that his glucose and galactose levels were within the normal range, as were his insulin and phenylalanine levels. Some of the values in the lipid panel were slightly above the normal range. Most concerning was his arterial blood pH, which was 7.0 ( normal range: 7.35 – 7.45 ) . Select all the substances for which a high blood concentration could result in acidosis.

a. Na +

b. CO 2

c. alanine

d. ketone bodies

e. lactic acid

Answer 1

b.Increased CO2 in blood , reacts ith ater to form carbonic acid which lowers the pH of blood and causes acidosis.

d.High concentrations of ketobodiies formed from fattyacids can lead to decrease n blood pH.

e.High lactic acid content in blood also decreses blood pH.

High sodium on concentraton increases blood volume and decreases proton concentration thus blood doesn't become acidic.Alanine is an activator of pyruvate kinase and may not lead to acidic conditions unless there is a decrease in oxygen concentration.
