Diabetes Mellitus (DM) is a prevalent, chronic metabolic condition characterized by the body’s impaired ability to process carbohydrates, fats, and proteins effectively due to insulin resistance or deficiency. This dysfunction leads to hyperglycemia, or elevated blood glucose levels, which, if poorly managed, can result in severe health complications. Effective nursing care is crucial in managing diabetes, focusing on accurate diagnosis and comprehensive care plans tailored to individual patient needs. This article provides a detailed guide to diabetes nursing diagnosis and care plan development, essential for healthcare professionals aiming to deliver optimal patient outcomes.
Understanding Diabetes Mellitus: Types, Hypoglycemia, and Hyperglycemia
Diabetes Mellitus encompasses several types, each with distinct etiologies and management approaches.
Type 1 Diabetes, often considered an autoimmune condition, involves the destruction of insulin-producing beta cells in the pancreas. Genetic predisposition and viral infections are believed to contribute to its development.
Type 2 Diabetes, the most common form, is characterized by insulin resistance, where the body’s cells do not respond effectively to insulin. This type typically develops gradually and is strongly linked to lifestyle factors.
Gestational Diabetes occurs during pregnancy in women who have not previously been diagnosed with diabetes. While it usually resolves after childbirth, it increases the mother’s risk of developing type 2 diabetes later in life and poses risks to the newborn.
Prediabetes is a precursor to type 2 diabetes, marked by blood glucose levels higher than normal but not yet meeting the criteria for diabetes diagnosis. It is a critical stage for intervention to prevent progression to type 2 diabetes.
Hypoglycemia, or low blood glucose, is defined as levels below 70 mg/dL. It is a potentially dangerous condition requiring immediate intervention. Causes include excessive insulin, insufficient carbohydrate intake, strenuous physical activity, or alcohol consumption.
Hyperglycemia, conversely, refers to high blood glucose levels. It occurs when there is insufficient insulin in the bloodstream. Hyperglycemia is indicated by a fasting blood glucose level exceeding 125 mg/dL or a level of 180 mg/dL or higher one to two hours post-meal. Factors contributing to hyperglycemia include dietary indiscretions, inactivity, illness, stress, and improper medication management.
Nursing Assessment for Diabetes Mellitus
A thorough nursing assessment is the cornerstone of effective diabetes care. It involves gathering comprehensive data across physical, psychosocial, emotional, and diagnostic domains.
Review of Health History
1. General Symptom Assessment: Nurses should be adept at recognizing the signs and symptoms of both hypoglycemia and hyperglycemia.
Hypoglycemia symptoms may include:
- Palpitations
- Tremors
- Diaphoresis
- Anxiety
- Confusion
- Dizziness
- Hunger
Hyperglycemia symptoms can manifest as:
- Polyuria (frequent urination)
- Polydipsia (increased thirst)
- Polyphagia (increased hunger)
- Blurred vision
- Paresthesia in extremities
- Fatigue
- Headaches
- Balanitis in men
- Nausea and vomiting in gestational diabetes
2. Diabetes Duration and Treatment History: Understanding the duration of the patient’s diabetes and their past and current treatments is vital. Long-term diabetes complications are directly linked to the degree of glycemic control.
3. Age at Diagnosis: The age of onset can provide clues about the type of diabetes. Type 1 often manifests in childhood or adolescence, while type 2 is more common in adults over 40.
4. Risk Factor Investigation: Assessing both non-modifiable and modifiable risk factors is crucial for personalized care and risk reduction strategies.
Non-modifiable risk factors:
- Family history: Genetic predisposition significantly increases diabetes risk.
- Race/Ethnicity: Certain ethnicities, including Black, Hispanic, American Indian, and Asian Americans, have a higher prevalence of type 2 diabetes.
- Age: Risk increases with age, particularly for prediabetes and type 2 diabetes.
- Autoimmune conditions: Conditions that trigger autoimmune responses can lead to type 1 diabetes and LADA.
- Hormonal imbalances: Can contribute to gestational and type 2 diabetes by causing insulin resistance.
Modifiable risk factors:
- Obesity and unhealthy diet: High-fat, high-calorie diets and obesity are major contributors to insulin resistance and diabetes.
- Smoking: Smokers have a significantly higher risk of type 2 diabetes and experience greater difficulty managing their condition.
- Excessive alcohol consumption: Can impair insulin sensitivity.
- Sedentary lifestyle: Physical inactivity increases insulin resistance.
- Chronic conditions: Hypertension and hyperlipidemia elevate the risk of diabetes and its complications.
5. Yeast Infection History: Recurrent yeast infections can be indicative of poorly controlled diabetes due to elevated glucose levels promoting yeast proliferation.
6. Complication Assessment: Assess for existing diabetes-related complications, as early detection and management are critical. Potential complications include:
- Cardiovascular disease: Hyperglycemia damages blood vessels, increasing the risk of heart disease, stroke, and peripheral artery disease.
- Neuropathy: Nerve damage from prolonged hyperglycemia can cause pain, numbness, and increase the risk of foot ulcers and amputations.
- Renal disease (Nephropathy): Damage to kidney blood vessels can lead to kidney failure.
- Retinopathy: Damage to retinal blood vessels can cause vision impairment and blindness.
- Foot damage: Neuropathy and poor circulation increase the risk of foot ulcers and infections.
- Depression: The chronic nature of diabetes management can contribute to depression.
7. Blood Glucose Monitoring Records: Reviewing patient-maintained blood glucose logs helps identify patterns of hypo- and hyperglycemia and assess the effectiveness of current management strategies.
Physical Assessment
Physical examination findings can vary, particularly in patients with well-managed diabetes.
1. Blood Pressure and Respiratory Rate Monitoring: Hypertension is common in diabetic patients. Orthostatic hypotension may indicate autonomic neuropathy. Kussmaul respirations may suggest diabetic ketoacidosis (DKA).
2. Lower Extremity Pulse Palpation: Assessing dorsalis pedis and posterior tibialis pulses is vital to evaluate for peripheral vascular disease.
3. Foot Assessment: Comprehensive foot exams are essential to identify neuropathy and signs of potential ulceration. Use monofilament testing, reflex testing, and vibration perception tests to assess sensory neuropathy.
4. Weight Assessment: Unexplained weight loss can occur in type 1 diabetes due to glycosuria and dehydration. Weight gain is common in type 2 diabetes and can exacerbate insulin resistance.
Diagnostic Procedures
Blood glucose tests are central to diabetes diagnosis and monitoring.
1. Blood Glucose Testing:
Type 1 DM Diagnostic Criteria:
- Fasting plasma glucose ≥ 126 mg/dL
- Random plasma glucose ≥ 200 mg/dL in patients with symptoms
- HbA1c ≥ 6.5%
Type 2 DM Diagnostic Criteria:
- Similar criteria to Type 1 DM, often diagnosed via fasting glucose and HbA1c.
Prediabetes Diagnostic Criteria:
- Fasting blood sugar 100-125 mg/dL
- 2-hour post-oral glucose tolerance test (OGTT) glucose 140-200 mg/dL
Gestational Diabetes Screening:
- Typically screened at 24-28 weeks gestation.
- 1-hour glucose challenge test; if positive (>140 mg/dL), a 3-hour OGTT is performed for confirmation.
2. Additional Lab Tests:
- Urine albumin: To detect early diabetic nephropathy, especially in type 1 DM.
- Serum lipids: Routine monitoring as diabetes increases cardiovascular risk.
- Thyroid function tests: Annual screening recommended due to increased hypothyroidism prevalence in diabetic patients.
