Aggregate the core assignment instructions: analyze the pathophysiology of a diabetes complication, relate its etiology and clinical manifestations, assess the appropriateness of specified treatments, and propose improvements supported by evidence-based research. The case involves a 21-year-old female with poorly managed Type I diabetes, presenting with signs consistent with diabetic ketoacidosis (DKA), including hyperglycemia, dehydration, fruity odor, and altered mental status. The student must summarize these aspects, identify appropriate interventions, and support their findings with scholarly sources.

Diabetic ketoacidosis (DKA) is a serious acute complication predominantly associated with Type I diabetes mellitus, characterized by hyperglycemia, metabolic acidosis, and ketonemia. The pathophysiology of DKA involves an absolute or relative deficiency of insulin coupled with an increase in counter-regulatory hormones such as glucagon, catecholamines, cortisol, and growth hormone. This hormonal imbalance results in increased hepatic gluconeogenesis and glycogenolysis, leading to elevated blood glucose levels. Simultaneously, the deficiency of insulin impairs glucose uptake by peripheral tissues, exacerbating hyperglycemia while promoting lipolysis—breaking down fat stores into free fatty acids, which are converted into ketone bodies in the liver. The accumulation of ketones decreases blood pH, producing metabolic acidosis, which is a hallmark of DKA (Kitabchi et al., 2009).

The etiology of DKA typically involves factors such as missed insulin doses, infections, stress, or other physiological stressors. In the case of A.M., her failure to administer insulin due to her illness and inability to maintain her diet has precipitated her state of uncontrolled hyperglycemia and ketosis. The clinical manifestations align with the pathophysiology, including dehydration (indicated by dry skin and hypotension), rapid deep breathing (Kussmaul respirations linked to metabolic acidosis), fruity odor of the breath (due to acetone), altered mental status, and electrolytic disturbances such as elevated potassium levels (Tosh et al., 2010).

Physiologically, the dehydration resulting from osmotic diuresis occurs due to hyperglycemia exceeding renal reabsorption capacity, leading to glycosuria and water loss. This process accounts for her tachycardia and hypotension, as well as her decreased urinary output. Elevated serum potassium levels, despite total body potassium depletion, occur due to extracellular shifts prompted by acidosis and insulin deficiency (Gosmanov et al., 2012).

The standard treatments for DKA focus on correcting dehydration, electrolyte imbalances, and hyperglycemia. Administration of intravenous fluids such as Lactated Ringer’s solution helps restore circulating volume, improve tissue perfusion, and dilute serum glucose levels. Insulin therapy, typically via continuous infusion, facilitates glucose uptake, inhibits lipolysis, and reduces ketone production. Electrolyte management, especially potassium, is critical because insulin administration can precipitate hypokalemia, despite initial hyperkalemia. In this case, careful monitoring and replacement of potassium are essential as insulin therapy progresses (Umpierrez et al., 2013).

Additional interventions such as bicarbonate therapy are controversial and generally reserved for severe acidosis (pH

Considering the treatment plan prescribed in this case, some orders warrant scrutiny. The administration of 60 mg IV furosemide may be questionable because diuretics can exacerbate dehydration and electrolyte imbalances unless there is concurrent volume overload. The insulin administration, with both NPH and regular insulin, requires careful titration, as rapid onset insulin (regular) is appropriate for acute management, whereas NPH is long-acting and may not be necessary in this context. Moreover, the prescribed blood cultures, stool studies, and other lab testing are appropriate to identify underlying triggers such as infections or gastrointestinal causes, which are common precipitating factors of DKA.

In conclusion, A.M.'s presentation aligns with the classic features of DKA caused by insulin deficiency leading to hyperglycemia and ketosis. Treatment strategies should prioritize rehydration, insulin therapy with close monitoring of electrolytes, and addressing underlying precipitating factors. Evidence-based guidelines emphasize the importance of individualized fluid and insulin management to minimize complications and promote recovery. Future management must carefully balance the correction of dehydration, electrolyte derangements, and acidosis to optimize outcomes for diabetic patients experiencing acute crises.
