2.5L of water

40mmol of potassium, sodium and chloride

150g of glucose
QuestionChoice
NICE guidance suggests for maintenance fluids alone patients should receive:

- 25 to 30ml/kg/day of water

- 1mmol/kg/day of potassium, sodium and chloride

- Approximately 50 to 100g/day of glucose to limit starvation ketosis

This therefore means this is the most accurate representation of the patient’s maintenance fluid requirements in a 24-hour period.

2.5L of water

80mmol of potassium, sodium and chloride

50g of glucose
QuestionChoice
This is an insufficient quantity of potassium, sodium and chloride for an 85kg patient in one day.

c
2.0L of water

20mmol of potassium, sodium and chloride

50g of glucose
QuestionChoice
This is over the patient’s daily water requirement and the potassium amount is incorrect as potassium only comes in 20 and 40mmol bags, therefore the option has to be 60mmol or 80mmol.

Maintenance fluid requirements for adults are approximately 25-30 ml/kg/day of water, alongside electrolytes and glucose to prevent starvation ketosis.
A 57-year-old male is kept nil-by-mouth prior to an elective knee replacement.

The patient weighs 85 kilograms and he has no known heart failure or renal impairment.

Which of the following is the closest to his maintenance fluid requirements in a 24-hour period?
