How would you differentiate between diabetic ketoacidosis (DKA) and hyperosmolar hyperglycemic syndrome (HHS)? Correct Answer: Both of these 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. Juan is a 42 year old male with complaints of nausea and vomiting for 3 days and has been unable to keep anything down in that time. He has not taken any of his medications due to the nausea and vomiting. Your assessment reveals the following data: Significant History Type 2 DM x 4 years, HTN Medications Lisinopril 10 mg daily Metformin 1000 mg po daily Glipizide 5 mg po daily Physical Exam Pale, lethargic gentleman Skin is very dry VS 94/64 P 112 RR 30 T 99.4 wt 195 pounds ht 5’11 » Lungs clear bilaterally, rapid respiration CV : RRR, no murmurs or gallops Abd: soft, non-tender, positive bowel sounds Labs: Hb 146 Hct 58% Cr 4.9 Bun 53 Cholesterol 238 Na 126 K 5.6 CL 95 Ca 8.8 Gluc 722 Phosphorus 5.8 Ketone Moderate AST 248 Alk Phos 132 ABG’s ph 7.01 Pco2 20 Po2 100 Sat 98% (on room air) HCO3 7.5 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 Juan is a 42 year old male with complaints of nausea and vomiting for 3 days and has been unable to keep anything down in that time.

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. Juan is a 42 year old male with complaints of nausea and vomiting for 3 days and has been unable to keep anything down in that time. He has not taken any of his medications due to the nausea and vomiting.

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. ................................................................................................CONTINUE
