How would you differentiate between diabetic ketoacidosis (DKA) and hyperosmolar hyperglycemic syndrome (HHS)?
Correct
Answer: Both of these
... [Show More] conditions will include high levels of blood glucose readings. DKA will exhibit acidosis and urinary ketones while HHS will not. Treatment for each condition is similar with fluid bolus and infusion as well as insulin
bolus and infusion.

What are the appropriate initial orders to treat this patient?
Correct
Answer: Admission to the ICU
Normal saline IV bolus to counter the vascular dehydration that has
occurred.
Bolus insulin dose followed by an insulin drip
Electrolyte and blood glucose monitoring frequently fluid resuscitation and insulin administration.
Bicarbonate is typically not administered unless the pH is below 7 Assess the patient for presence of any infection that may have precipitated this event

What is the “ corrected” sodium level for the hyperglycemia? What does this mean and how would it impact your treatment plan for this patient?
Correct
Answer: The equation for corrected sodium is:
Corrected sodium (mEq/L) = measure sodium (mEq/L) + 0.016 {glucose
(mg/dL)-100}.
Juans corrected sodium is 136.
126+ 0.016 {722-100} = 135.95
The measured serum sodium concentration should be corrected for the hyperglycemia by adding 1.6 mEq per L to the measured sodium value. Corrected serum sodium concentrations of greater than 140 mE1 per L and calculated total osmolalities greater than 330 most per kg of water are
associated with large fluid deficits.
If the corrected sodium is less than 135 mEq/L, then isotonic saline should be continued at a rate of 250 to 500 mL/ hour. If the corrected sodium is normal or elevate, then IV fluid is generally switched to 0.45 normal saline.
A 56 year old male with an acute COPD exacerbation is admitted to the ICU. He has type I diabetes and utilizes NPR and regular insulin twice a day to manage his diabetes. He is currently taking very little orally due to his shortness of breath. What would the best way to manage his diabetes and insulin needs in the ICU?
Correct
Answer: According to the American Diabetes Association (2019) guideline, basal long acting insulin should be administered once a day. Point of care blood glucose testing should be completed at least four times a day with sliding scale insulin
coverage. The stress of illness will require the need for insulin but the evolution of the patients condition, varying oral intake, and medications will cause variations in the patients blood glucose. Point of care testing with sliding scale coverage along with basal insulin is the most flexible method to meet the patients insulin needs while in the ICU.
A 56 year old male with an acute COPD exacerbation is admitted to the ICU. He has type I diabetes and utilizes NPR and regular insulin twice a day to manage his diabetes. He is currently taking very little orally due to his shortness of breath. What is the blood glucose goal for this patient in the ICU?
Correct
Answer: According to the American Diabetes Association (2019) guideline, pre-prandial blood glucose control of less than 126 is the goal. Post prandial no greater than 180. Hyperglycemia is associated with poor outcomes especially in
critical illness. According to the NICE-SUGAR study, patients with goals lower than this (considered intensive insulin therapy) had increased mortality.

What patient education would be important to provided related to sick day management of his diabetes (include management of insulin) ?
Correct
Answer: Monitor your blood sugar frequently when you are sick - at least every 4 hours
Keep a log of these readings in case you need medical care Take your usual dose of insulin as long as your blood
glucose readings do no indicated hypoglycemia
Basal insulin should be continued as normal.
Call your provider should your blood glucose remain higher than 240 consistently
Drink a glass of liquid (non-alcholic, caffeine free) every hour when sick.
Try to intake foods like gelatin, crackers, soup, broth, and
applesauce.
Check your urine for ketones every 4 hours regardless of
blood glucose readings.
If your testing indicates a large volume of ketones, contact your provider immediately.
A 37 year old female with a 20 year history of DM is post cholecystectomy with complications. She has been on four time daily blood sugar testing with sliding scale insulin coverage. She is preparing for discharge and wanted to return to her previous blood sugar management. Her pre-hospitalization insulin regime included:
NPH insulin 16 units in AM and 8 units in PM Regular insulin 8 units in am and 3 units in PM
She resumed this regime 2 days ago. Upon rounding this am, the patient tells the NP that she has woken up feeling awful. She is sweaty and shaky during the night and lethargic in the morning. The NP reviews her blood sugar readings and discovers this:
0300 0700 1200 1700
62 196 109 90
64 203 82 100
What is your working diagnosis for this patient?
Correct
Answer: Noctural hypoglycemia
