blood glc and urinalysis Flashcards
blood glc procedure
consent ensure pt has washed hands turn on monitor and put in test strip use lancet to prick side of finger blood to strip read result test ketones if hyperglycaemic
hypoglycaemia
<3
hyperglycaemia
> 11
normal range BG
4.2-6.3
fasting plasma glc values
normal: <6
intermediate: 6 - 6.9
diabetes: >7
random plasma glucose - what result what indicate diabetes
> 11
diabetic ketoacidsosis features
hyperglycaemia raised ketones (>3) acidosis
urinalysis procedure
- hand hygiene + gloves
- observe sample: clarity, colour, smell
- exp date reagent strips and take one out
- emerse in urine
- remove and start timer
- read results at corresponding tiem
urinalysis: leucoytes
UTI
urinalysis: nitrites
UTI (gram negative)
urinalysis: protein
proteinuria
nephrotic syndrome, UTI, PET
urinalysis: acidic pH
<4
uncontrolled diabetes
starvation, dehydration
DKA
urinalysis: alkaline pH
> 8
UTI
urinalysis: blood
UTI
nephritic syndrome
urinalysis: specific gravity low
renal abnormalities
high fluid intake
urinalysis: specific gravity high
dehydration
urinalysis: ketones
uncontrolled diabetes
DKA
starvation
urinalysis: glucose
diabetes –> blood Glc, HbA1c
cushings
renal tubular disease
urinalysis: leukocytes and nitrites
UTI
follow up urine culture
urinalysis: DKA signs
glucose
ketones
low Ph
urinalysis: high specific gravity and proteinuria
nephrotic syndrome
what do to if capillary blood glucose comes back hyperglycaemic
test for ketones
