61. Miss N, a 12 year old girl is suffering with diarrhoea for which the doctor
recommends she takes Dioralyte rehydration therapy with the following instructions:
Reconstitute the contents of one sachet with 200ml of water and take after every loose bowel motion.
Dioralyte sachets contain potassium chloride, sodium chloride, disodium hydrogen citrate and glucose and, when reconstituted with 1 litre of water, provide Na+ 60mmol, K+ 20mmol, Cl 60mmol, citrate 10mmol and glucose 90mmol. Over a period of three days, Miss N uses a total of 12 Dioralyte sachets.
The molecular weight of sodium is 23g/mol, chlorine is 35.5g/mol and potassium is 39g/mol.
Over the three days, what percentage of Miss N’s total sodium intake from Dioralyte is from sodium chloride? Give your answer to one decimal place.
