Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice.
From your description, I can deduct that 201 mg/dl is not a fasting blood sugar result. (because she had a long lasting
insulin injection 2 hours ago.)
It is not too high, don't worry. This result is not dangerous for your sister.
My advice is to increase 2 UI her insulin doses (you can start tomorrow with the increased dose) and to check her fasting and post prandial (2 hours after meals) blood sugar again.
If the result do not return to "normal diabetic range", I suggest to consult her treating doctor because your sister may need to change her insulin schedule to control her
diabetes.
About her vitals, her blood pressure is "a little bit" low, but is can be normal for the females. Anyway, if she take anti hypertensive drugs, I suggest to lower the doses of the medication.
Her
heart rate is OK.
Hope i have answered to all your questions. If you have other doubts,feel free and ask.
