Diabetic Ketoacidosis The American diabetes association (2011) defines diabetic ketoacidosis (DKA) as a medical emergency that can progress to a diabetic coma and death if not rapidly diagnosed and treated (American diabetes association (ADA), 2011). DKA is a complication associated with diabetes mellitus (DM) and is characterized by hyperglycemia due to a deficiency in insulin (Urden, Stacey, & Lough, 2010). Rapid diagnosis and aggressive treatment of DKA is crucial because it is potentially life threatening (Kitabchi, Rose, 2011). Nurses in the critical care setting are responsible for understanding the disease process of DKA as well as identifying its signs and symptoms so that patients can receive prompt treatment early before it progresses. This paper will discuss DKA and explore its epidemiology, etiology, pathophysiology, assessment, diagnosis, treatment, and nursing and interventions associated with it.
Epidemiology and Etiology DKA is a complication of type-one and type-two DM and is typically seen more in type-one diabetics because of they are deficient and lack the ability to produce insulin (Urden et al., 2010). Type-two diabetics can develop DKA but it is very rare and is usually precipitated in a patient who is severely ill (Diabetic ketoacidosis, 2011). Those most likely to develop DKA associated with type-two DM include Hispanics and African Americans (Diabetic ketoacidosis, 2011). The parameters that must be met for a positive diagnosis of DKA are a blood glucose greater than 250, pH less than 7.3, serum bicarbonate less than 15mEq/L, and moderate to severe ketonemia and or ketonuria (Urden et al., 2010). The yearly totals for patients diagnosed with DKA range from 4.6-8 incidences per 1000 patients and hospital costs for treatment of DKA are more

...assessment should take no more than a quick 10 second initial visual assessment upon seeing the patient when the patient first arrives into the ER. This is a quick head to toe visual assessment. Head: does the patient have any noticeable signs of trauma to it, what size and shape are the patient’s pupils, is her face symmetrical, is her tongue dry or moist, is she breathing normal through her nose and mouth? Chest: does the patient have any noticeable signs of trauma to the chest, are her shoulders symmetrical, is she breathing normal or rapidly, is she breathing with her chest or abdomen? Extremities: what is the color of her extremities, are they pink, pale, cyanotic, or blue; are there any noticeable signs of trauma to her extremities; is her skin moist or dry; what is the color of her nail beds? Abdomen: is there any noticeable sign of trauma to her abdomen, is she using her abdominal muscles to breathe, is her stomach flat or round? General: she is an elderly female, is she showing signs of pain or guarding any particular part of her body? The next part of the assessment parallels the Visual Assessment; this would be an assessment of what the RN hears from the patient from head to toe upon first initial arrival to the ER. Head: what does the patient’s breathing sound like, can the patient speak in clear sentences or is she dysphasic or slurred in her speaking, can the patient state her name, birthday, todays date, and where she is? Chest: Is there noticeable wheezing...

So feel free to shoot me any questions/comments! A little background: This study guide is the culmination of years of my own research. And after careful thought, I put into the study guide what I feel are the most important concepts you need to know for the RD/DTR exam. If you notice, I spent much time teaching you in detail the concepts you need to know, not just “spitting” you questions with little or no explanation. I believe this is important. I know you might be thinking “oh, how am I going to absorb and learn all this material?” I say, just read and answer the questions at your own pace. Simply test yourself and of course take some breaks along the way. Just take it one concept at a time. After you have mastered one concept, then move on to the next.
