Diabetes - Nursing Case Study

Pathophysiology

• Primary mechanism: In type 1 diabetes, autoimmune destruction of pancreatic β-cells leads to absolute insulin deficiency, impairing glucose uptake and resulting in hyperglycemia and ketoacidosis.

• Secondary mechanism: In type 2 diabetes, insulin resistance in peripheral tissues, coupled with progressive β-cell dysfunction, results in relative insulin deficiency, exacerbating hyperglycemia and increasing risk for metabolic syndrome.

• Key complication: Chronic hyperglycemia causes microvascular damage, leading to nephropathy, retinopathy, and neuropathy, while macrovascular complications heighten risks for cardiovascular disease and stroke.

Section 1

Initial Assessment Findings:

Upon arrival to the emergency department, the 55-year-old male presents with acute respiratory distress and chest pain, prompting an immediate and thorough assessment. His blood pressure remains critically elevated at 190/110 mmHg, suggesting poorly controlled hypertension. The tachycardia with a heart rate of 112 bpm and labored breathing with a respiratory rate of 28 breaths per minute are concerning for a possible cardiac event or exacerbation of heart failure. Oxygen saturation is dangerously low at 88% on room air, indicating significant hypoxemia. The patient exhibits peripheral edema, particularly in the lower extremities, and auscultation reveals bilateral crackles in the lung bases, consistent with pulmonary congestion.

Laboratory tests reveal a blood glucose level of 350 mg/dL, indicating severe hyperglycemia. Hemoglobin A1c is critically high at 10.2%, suggesting chronic poor glycemic control. Renal function tests show a serum creatinine of 2.5 mg/dL and an estimated glomerular filtration rate (eGFR) of 28 mL/min/1.73m², consistent with stage 4 chronic kidney disease. Electrolyte imbalances are noted, with hyperkalemia (potassium level at 5.8 mEq/L) and hyponatremia (sodium level at 130 mEq/L), which further complicate the clinical picture. An electrocardiogram (ECG) demonstrates ST-segment depression in the lateral leads, raising suspicion for myocardial ischemia or a non-ST elevation myocardial infarction (NSTEMI).

These findings necessitate urgent intervention, including stabilization of cardiac and respiratory status, correction of electrolyte imbalances, and optimization of blood glucose levels. The patient's complex interplay of diabetes-related complications, cardiovascular risk factors, and renal impairment presents a challenging case that requires advanced critical thinking to prioritize interventions and anticipate potential complications, such as progression to acute renal failure or decompensated heart failure. The healthcare team must carefully balance the management of these conditions to mitigate further deterioration while considering the patient's history and current medication regimen.

Section 2

New Diagnostic Results:

Following the initial stabilization of the patient, further diagnostic tests were ordered to gain a clearer understanding of the underlying issues and potential complications. A chest X-ray revealed significant cardiomegaly and pulmonary edema, confirming suspicions of heart failure exacerbation. Additionally, a transthoracic echocardiogram was performed, which demonstrated a reduced ejection fraction of 35%, indicating systolic heart failure. The echocardiogram also revealed mild mitral regurgitation, which could be contributing to the patient's pulmonary congestion and peripheral edema.

Further laboratory tests showed elevated cardiac biomarkers, with troponin I levels at 0.8 ng/mL, reinforcing the likelihood of an acute coronary syndrome, specifically NSTEMI. The patient's lipid profile was markedly abnormal, with a total cholesterol of 250 mg/dL, LDL cholesterol at 160 mg/dL, and triglycerides at 300 mg/dL, highlighting the need for aggressive lipid management to address cardiovascular risk. Additionally, a urine analysis indicated significant proteinuria with a protein-to-creatinine ratio of 3.5 g/g, consistent with diabetic nephropathy and further evidence of advanced kidney disease.

These new diagnostic results underscore the complexity of the patient's condition, necessitating a multifaceted approach to management. The healthcare team must carefully prioritize interventions to stabilize heart function, manage fluid overload, and address the acute coronary event while also considering the long-term implications of the patient's poorly controlled diabetes and renal insufficiency. The integration of these findings into the patient's care plan will require advanced clinical judgment and coordination among the multidisciplinary team to balance the immediate needs with the prevention of further complications. This will set the stage for subsequent decisions regarding potential interventions such as diuretics, inotropic support, antiplatelet therapy, and possible revascularization strategies.

Section 3

Change in Patient Status:

In the days following the initial interventions, the patient exhibited a significant change in status, characterized by worsening respiratory distress and decreased urine output. Vital signs indicated a blood pressure of 90/60 mmHg, heart rate of 112 beats per minute, respiratory rate of 28 breaths per minute with labored breathing, and oxygen saturation dropping to 88% on a 4L nasal cannula. The patient appeared diaphoretic and cyanotic, with auscultation revealing bilateral crackles extending to the mid-lung fields, suggestive of escalating pulmonary edema. Despite the administration of diuretics, the patient’s fluid overload persisted, necessitating further evaluation of renal function and potential acute kidney injury.

Laboratory tests revealed a serum creatinine level increased to 3.0 mg/dL from a baseline of 1.8 mg/dL and a blood urea nitrogen (BUN) of 45 mg/dL, indicating a decline in renal function. Additionally, arterial blood gas analysis showed a pH of 7.32, PaCO2 of 55 mmHg, and PaO2 of 60 mmHg, consistent with respiratory acidosis secondary to hypoventilation and impaired gas exchange. The patient’s persistent tachycardia and hypotension, coupled with these lab findings, suggested a possible progression to cardiogenic shock, requiring urgent intervention and reevaluation of the current management strategy.

This change in status demands immediate and critical clinical reasoning to address the intertwined complications of heart failure exacerbation, renal impairment, and potential respiratory failure. The healthcare team must consider escalating to more aggressive interventions, such as intravenous vasopressors for hemodynamic support, non-invasive ventilation to improve oxygenation, and potentially renal replacement therapy if the renal function continues to deteriorate. The evolving clinical picture underscores the need for close monitoring and dynamic adjustment of the treatment plan to stabilize the patient and prevent further deterioration.

Section 4

The healthcare team elected to initiate non-invasive ventilation (NIV) to address the patient's hypoxemia and respiratory acidosis. Within the first hour of applying bilevel positive airway pressure (BiPAP), there was a marginal improvement in oxygen saturation, rising to 92%, and a slight reduction in respiratory rate to 24 breaths per minute. However, the patient continued to exhibit signs of significant distress, with persistent tachycardia and hypotension. The decision was made to commence a low-dose norepinephrine infusion to stabilize blood pressure and support organ perfusion, recognizing the high risk of cardiogenic shock.

Despite these interventions, the patient's urine output remained critically low, averaging less than 10 mL/hour over several hours, pointing towards worsening acute kidney injury. Repeat laboratory tests showed further derangement, with serum creatinine climbing to 4.0 mg/dL and BUN increasing to 60 mg/dL, indicating severe renal impairment. In conjunction with the nephrology team, the possibility of initiating renal replacement therapy was discussed as the patient's fluid overload and electrolyte imbalances became more pronounced, evidenced by a potassium level of 5.8 mEq/L.

Simultaneously, the patient developed new-onset confusion and agitation, raising concerns about possible cerebral hypoxia or metabolic disturbances. A stat CT scan of the head was ordered to rule out any acute intracranial events, while close monitoring of blood glucose levels was maintained to prevent hyperglycemic exacerbations in the context of diabetes. This evolving clinical scenario necessitated a multidisciplinary approach, with continuous bedside evaluation and dynamic adjustments to the management plan to address the complex interplay of heart failure, renal failure, and respiratory compromise. The team prepared for potential escalation to invasive mechanical ventilation and dialysis should the patient's condition continue to deteriorate.

Section 5

As the patient's clinical status continued to evolve, a new diagnostic result added complexity to the situation. The CT scan of the head returned with no acute intracranial abnormalities, effectively ruling out a stroke or hemorrhage as the cause of the patient's confusion and agitation. However, the metabolic panel revealed alarming hypernatremia, with serum sodium levels rising to 155 mEq/L, likely contributing to the patient's neurological symptoms. This finding indicated severe dehydration and prompted immediate adjustments in fluid management. The healthcare team initiated a carefully calculated infusion of 0.45% saline to gradually correct the sodium imbalance, aiming to mitigate the risk of cerebral edema from too rapid a correction.

Meanwhile, the patient's respiratory status showed signs of further compromise. Despite the initial marginal improvement with BiPAP, arterial blood gas analysis revealed persistent respiratory acidosis with a pH of 7.28 and elevated partial pressure of carbon dioxide (PaCO2) at 58 mmHg. The patient's oxygen saturation hovered around 90%, and the work of breathing remained visibly labored, with accessory muscle use and intercostal retractions. These findings indicated that non-invasive ventilation might not be sufficient, and the team deliberated on the urgent need for transitioning to invasive mechanical ventilation to ensure adequate ventilation and prevent respiratory failure.

Compounding the challenge, the patient's cardiovascular status remained precarious. Despite the norepinephrine support, blood pressure readings fluctuated, with systolic levels barely maintaining at 90 mmHg, indicating borderline perfusion. Tachycardia persisted at 115 beats per minute, suggesting ongoing cardiac strain. The decision was made to titrate the norepinephrine infusion carefully and consider additional inotropic support if needed. The interdisciplinary team, including cardiology, nephrology, and critical care specialists, convened to reassess the therapeutic goals and prepare for imminent interventions such as dialysis and intubation. This strategic collaboration underscored the necessity of meticulous clinical reasoning to navigate the patient's complex and rapidly deteriorating condition.
