Q

how is diabetes managed if ketonuria is present?

Q

general algorithm for DM diagnosis?

A

random plasma glucose over 6.1 > symptoms of hyperglycaemia

  • if present > single plasma glucose measurement (random or fasting)
  • if no > 2 separate plasma glucose measurements at least 4 weeks apart (fasting >7 on both tests or fasting >7 and random >11.1)

Q

describe the initial management of type 2 diabetes?

A
register with SCI-DC
retinopathy screening
give support and information
refer for education
check baseline measures (BMI, BP, urine etc)

Q

recommendations for food and fluids in acutely unwell type 1 diabetics?

A

100-200 ml (1 glass every hr)
regular carb intake regardless of blood glucose (means you can give insulin which treats the ketosis)
- take in the form of high sugar/nutrient drinks

Q

when do you monitor blood glucose and ketones in an acutely unwell patient?

A

blood glucose = every 4 hrs

ketones = check regardless on blood glucose in acutely unwell/vomiting and pregnant patients

17
Q

at what ketone level must action be taken and what is done?

A

above 0.6 mmol/L
increase insulin dose by 10% if elevated BG or dose of rapid acting insulin
recheck BG and ketones in 1-2 hrs

18
Q

how is insulin delivery modified in illness?

A

NEVER OMIT INSULIN
often more is required if BG is high or to correct ketosis
extra insulin can be given 2-4 hourly to address elevated BG in addition to routine insulin

19
Q

how is ketosis managed if BG is low or normal?

A

IV fluid and insulin and patient should be admitted to hospital

20
Q

how do you calculate correct dosage of extra rapid acting insulin?

A

increase usual dose by 10% if recent BG trend = >10
use short acting isulin for STAT dose
calculate STAT dose as 10-20% of the patients daily dose of insulin

21
Q

when should a diabetic be admitted to hospital?

A
inability to swallow or keep fluids down
persistant vomiting
persistent diarrhoea
ketonuria/ketonaemia with or without hyperglycaemia
when ketoacidosis is clinically abvious
22
Q

how would you advice a type 2 diabetic who has been unwell with vomiting and diarrhoea during previous day/night?

A

oral diabetes tablets should be continued apart from metformin if there is severe infection or dehydration
increase oral fluids and take carbs if possible and maintain insulin delivery
