Scenario 1 The following blood test result contains the measured values of ten blood constituents and their “normal” reference range. Component Value Reference Range Na+ 130 135-145 mmol/L K+ 3 3.5 – 5.5 mmol/L Ca+ 2.31 2.25 – 2.65 mmol/L Cl- 101 95 – 110 mmol/L Cholesterol 190 120 -199 mg/dL Protein 75 60 – 82 g/L Glucose 84 70-120 mg/dL Erythrocyte 5.6 x 1012 4.7-6.1 x 1012/L pH 7.31 7.35 – 7.45 CO2 58 35 – 45 mmHg Question 1. Categorise each of the ten (10) blood constituents in the table above as atom, ion (measurement of ion), molecule, macromolecule, or cell (5 marks) Question 2. a) The concentration of Na+ in the blood test sits outside of the reference range. Considering your understanding of tonicity, which type of solution would this be referred to? (1 mark) b) Referring to BOTH osmosis and diffusion, what is likely to happen to a cell exposed to this type of solution and briefly explain why? (4 marks) Question 3. In response to the pH and CO2 levels (refer to the table above), you have noticed that the patient’s breathing pattern begins to change. This is a physiological response of the body to attempt to maintain blood pH homeostasis. Referring to the specific components of the bicarbonate buffer system in your answer, explain how the patient’s breathing may change as a response to these values (i.e., pH and CO2) and why?
