Question
A 68-year-old woman with a history of kidney dysfunction is admitted to your hospital clinic. An arterial blood gas is drawn. You notice that she has a mild acidemia (decreased blood pH). You do a complete review of symptoms and take a thorough diet and exercise history and find nothing out of the ordinary except for her impaired renal function. What best explains her acidemia?She has a metabolic acidosis from increased HCO3- production or intake. She has a metabolic acidosis from increased H+ production or intake. She has a metabolic acidosis from decreased HCO3- excretion. She has a metabolic acidosis from decreased H+ excretion.

Explanation / Answer
If an old patient with a history of kidney dysfunction is admitted in hospital and noticed that patient suffering from mild acidemia(decreased blood pH).
This condition is termed as 'Acidosis' in medical terminology. There are many types of acidosis e.g. Respiratory acidosis. Metabolic acidosis etc. But we have done complete review of her diet and exercise history, there is nothing found abnormal except her (patient) renal dysfunction. So it is the case of metabolic acidosis.
Metabolic acidosis is caused by different factors : (a) decreased HCO3- producton (b) Increased H+ production (c) Increased HCO3- excretion (d) decreased H+ excretion.
Hence, According to given options best explanation of his acidemia is metabolic acidosis that caused by decreased H+ excretion by kidney due to impaired renal function
