WorksheetsAcid-Base Balance and Metabolic Disorders Worksheet
Total questions: 10
Worksheet time: 11mins
The kidneys contribute to acid base balance by
Secretion of ammonia
Retention of bicarbonate
Increased ketogenesis
Increasing the pCO2
Metabolic acidosis can result from
Reduction of H+ excretion by the kidneys
Increase in HCO3- reabsorption
Hyperventilation
Respiratory depression

A 10-year-old child with a known case of type 1 DM presents with confusion. The blood glucose level is 353 mg/dl and pH=7.0. What is the metabolic abnormality?
Respiratory acidosis
Metabolic alkalosis
Metabolic acidosis
Respiratory alkalosis
A patient with COPD has the following blood gases: pH 7.26, PCO2 59mmHg, HCO3- 42. Which of the following conditions is presenting?
Partially compensated Respiratory alkalosis
Partially compensated Respiratory acidosis
Fully compensated Metabolic alkalosis
Fully compensated Metabolic acidosis
All of the following are examples of HAGMA except?
DKA
Diarrhoea
AKT
Inborn error of metabolism
Which of the following is not done before drawing blood for arterial blood gas analysis?
Allen's test
Rinse syringe with heparin
Flexion of wrist
Placing needle at 45 degree angle
A patient with CKD has a pH of 7.21 and elevated serum bicarbonate levels. Which is the most likely acid base disorder?
Respiratory alkalosis
Respiratory acidosis
Metabolic acidosis
Metabolic alkalosis
Renal compensation in metabolic acidosis takes time because:
Initially the pH of tubular fluid increases
Low pH normally decreases bicarbonate excretion
It takes hours to days for kidney to synthesize enzymes that produce NH4+
Other ions in the tubule interfere with buffer action
The kidney excretes H+ in the form of titratable acid. Which of the following is a buffer that forms a titratable acid excreted in urine?
Ammonium
Bicarbonate
Histidine
Phosphate
