Questions on DKA
1-During management of DKA a rapid decline in blood sugar (> 6mmol/L/hr) can result in :-Hyperkalemia
Hypertension
Deterioration in the level of consciousness
Compensatory acidosis
2-We can use insulin subcutaneously during management of DKA whenever :-
RBS reach 300mg/dlPatient starts passing urine
Serum potassium normalized
Vomiting ceased
3-Insuline can not be given subcutaneously during initial management of DKA because of :-
AcidosisSevere hyperglycemia
Dehydration
Electrolytes disturbance
4-Regarding K+ level in DKA which of the followings sentence is true :-
Deficient can be corrected by using either K+ sparing diuretic.
If the serum K+ is normal initially no need to follow serum K+ level later
Replacing K+ during 1st hour of management is not recommended.
KCL should be replaced when RBS is below 200mg/dl
5-Of the followings scenario who can fulfill the criteria for DKA diagnosing :-
12 year old girl recently diagnosed with NHL, starts chemotherapy and developed polyuria, polydypsia, acidosis and his RBS is 460mg/dl, and +++ ketone in urine.
Patient with type 1 DM developed pyloric obstruction, ketones in urine +++
Patient with type 2 DM developed acute MI, RBS 550mg/dl, serum bicarbonate level = 23mmol/C
Patient with diabetic nephropathy, starts peritoneal dialysis, his RBS=330mg/dl, S. bicarbonate =16 mmol/C, ketone in urine +
